[00:38:52] <XXCoder> hey
[00:47:59] <PetefromTn_> man I swear this couch has some sort of magical suction holding my ass down on it today. I can't seem to get out in the shop to do much of anything LOL
[00:49:45] <Tom_itx> after raking the yard, i'm kinda with ya there
[00:51:07] <ssi> I have days like that
[00:51:12] <ssi> fortunately lately I haven't been
[00:51:14] <ssi> I've been coding my ass off
[00:51:16] <ssi> in the hangar
[00:51:22] <ssi> sitting on a stool, wishing I had a real chair
[00:51:28] <ssi> my ass is literally getting coded off :(
[00:51:32] <Tom_itx> ssi, how's the sserial code coming?
[00:51:36] <ssi> it's getting there
[00:51:48] <PetefromTn_> all the money you spend on Schtuff and you can't bring yourself to buy a nice shop chair? ;)
[00:51:51] <ssi> I'm hunting down bugs in the way we pack/unpack and scale signed vals
[00:51:59] <ssi> PetefromTn_: I'm working at a 30" bench, so a regular chair won't work
[00:52:06] <ssi> I need like a high office chair
[00:52:10] <ssi> or a proper low bench to code at :)
[00:52:32] <ssi> coding in the shop isn't ideal, but this is where all the servo electronics are set up
[00:54:39] <PetefromTn_> I got parts to make but my eye is still bothering me and I feel kinda crappy so I am here watching Alexander on netflix and hoping tomorrow my eye feels fully healed and I can get on with it.

[00:57:55] <zeeshan> whats wrong with eye
[00:59:05] <PetefromTn_> got some cast iron grinding swarf in it accidentally yesterday at Addicted blowing out the ports with compressed air
[00:59:53] <malcom2073> You should get that looked at, buddy of mine had that happen, it rusted and got really gross
[01:00:02] <Tom_itx> yeah make sure you got it out
[01:00:20] <Tom_itx> it can feel like it's still there if you scratched it
[01:00:28] <PetefromTn_> I'm pretty sure it's out but it usually takes a day or three to fully heal
[01:01:49] <zeeshan> doh
[01:02:13] <Tom_itx> zeeshan, what have you gotten done with your lathe?
[01:03:05] <zeeshan> 0
[01:03:56] <Tom_itx> got the hydraulics figured out yet?
[01:04:10] <zeeshan> 0
[01:04:52] <ssi> Tom_itx: are you just going around asking everyone the status of their projects?
[01:05:02] <ssi> heads up everyone, looks like we have a damn project manager in our midst ;)
[01:05:10] <ssi> if he asks us to scrum, I vote mutiny
[01:05:24] <zeeshan> hehe
[01:05:38] <PetefromTn_> MUTINY!!!!
[01:05:43] <Tom_itx> well i don't have anything to work on so i ask
[01:05:47] <ssi> :D
[01:05:52] <ssi> get a job, hippie!
[01:06:00] <Tom_itx> i got a full time job
[01:06:06] <PetefromTn_> RAGE INTO THE NIGHT!!!!!
[01:06:09] <Tom_itx> no time to play with the fun stuff
[01:06:18] <PetefromTn_> sorry I got carried away ;)

[01:09:59] <ssi> sweeeeet
[01:10:05] <CaptHindsight> how many cubic feet of iron are in a typical cnc lathe with 12" swing and 40" centers?
[01:10:25] <ssi> CaptHindsight: dunk one in a bathtub and use archimedes' principle to figure it out :D
[01:10:27] <malcom2073> ssi: Have you met Joe Justice?
[01:10:31] <malcom2073> the scrum inc guy

[01:10:54] <CaptHindsight> ssi: do you gave a tub big enough that I can borrow?
[01:11:10] <ssi> malcom2073: I know there was a guy named joe that came around and gave mandatory scrum training
[01:11:11] <malcom2073> CaptHindsight: About 1000lbs worth?
[01:11:14] <ssi> might have been him
[01:11:15] <ssi> but I skipped those :)
[01:11:18] <malcom2073> ssi: Did he say "Awesome" a lot?
[01:11:24] <malcom2073> Like... a LOT
[01:11:27] <ssi> dunno
[01:11:29] <malcom2073> heh
[01:11:50] <ssi> yea I think that was him
[01:11:52] <ssi> found a pic
[01:11:57] <malcom2073> Heh
[01:12:07] <malcom2073> I worked with him for a weekend on his wikispeed project last year
[01:12:09] <malcom2073> He's uh....
[01:12:13] <malcom2073> Excited.
[01:12:16] <ssi> :D
[01:12:26] <ssi> it's good to be passionate I guess?
[01:12:30] <malcom2073> I suppose
[01:12:35] <ssi> although he could have picked something less terrible to be passionate about :D
[01:12:38] <malcom2073> Lol
[01:12:40] <CaptHindsight> Cast iron 6800 - 7800 Density (kg/m3) but I need lbs/ft^3 :)
[01:12:40] * ssi is not a big fan of agile
[01:12:42] <malcom2073> He's passionate about everything
[01:13:00] <malcom2073> I told him we should go get burgers for lunch, and he said "Dude that's AWESOME!" and high fived everyone
[01:13:08] <ssi> CaptHindsight: if only there were a hyper intelligent search engine that you could just ask for that answer
[01:13:18] <ssi> malcom2073: ahahaha
[01:13:21] <CaptHindsight> or some sort of converter
[01:14:00] <ssi> https://www.google.com/?gws_rd=ssl#q=convert+7800+kg%2Fm3+to+lb%2Fft3
[01:14:09] <ssi> google is surpristingly smart about that shit
[01:14:16] <CaptHindsight> nah too much gobbtygook
[01:14:24] <ssi> um
[01:14:26] <ssi> 487
[01:14:27] <ssi> is the answer
[01:14:39] <ssi> I know clicking a link is tough
[01:14:55] <malcom2073> So... 2.5 cubic feetish
[01:15:14] <malcom2073> At least, that's what in my 12x36
[01:15:26] <malcom2073> Assume a 40 would have a bit more, so there's the weight of the motor/spindle

[01:16:42] <Crom> ARGH#*&$()#&)_*(#$#^$)_#($*+#($*#$%#*($
[01:16:54] <Tom_itx> that good?
[01:16:58] <malcom2073> Well yeah, mine is a lightweight gap bed
[01:17:20] <Crom> the 3040 is SOOOO flexy.. 0.030 any whichway!
[01:17:28] <malcom2073> Well.... yeah
[01:17:28] <malcom2073> heh
[01:17:33] <malcom2073> It is made of aluminum
[01:17:36] <ssi> you expected what exactly?
[01:17:47] <ssi> my buddy dennis is just getting into machine stuff
[01:17:55] <Crom> the Reprap is setup for 3mm, and it handles it badly..., the K40 laser cutter IS WORKING! YEAH!
[01:17:56] <ssi> he started with reprap, then he built a shapeoko engraver
[01:18:04] <ssi> and he was talking to me about 3040 type machines the other day
[01:18:07] <ssi> called it a mill
[01:18:12] <ssi> I said "it's not a mill, it's a router"
[01:18:18] <ssi> "but they call it a mill on the website!"
[01:18:25] <PetefromTn_> jeez man is it me or do all the movies on netflix and at redbox suck azz lately?
[01:18:26] <ssi> "... it's not a mill, it's a router"
[01:18:30] <Crom> it's not a router, it's a cheap engraver
[01:18:37] <ssi> yeah that's probably more accurate :P
[01:18:46] <ssi> it's definitely not a mill :)
[01:18:48] <malcom2073> Eh, the runout on the spindles make it not an engraver either
[01:18:51] <CaptHindsight> 0.030 thats nothing, I had one that had 0.125" lash out of the box
[01:18:53] <Tom_itx> PetefromTn_, speaking of... saw 007 last night
[01:19:09] <PetefromTn_> the new one?
[01:19:13] <Tom_itx> yeah
[01:19:17] <Tom_itx> true bond form
[01:19:18] <CaptHindsight> Tom_itx: how was it?
[01:19:22] <PetefromTn_> I like craig
[01:19:34] <Tom_itx> i like bond so i'm gonna say it was good
[01:19:37] <CaptHindsight> he looks like a plumber to me
[01:19:45] <Tom_itx> first time in imax for me though so it was pretty awesome
[01:19:48] <PetefromTn_> ?
[01:19:48] <CaptHindsight> "ok I am here to fix toilet"
[01:20:04] <Tom_itx> yeah he has that look...
[01:20:04] <ssi> meine dispatcher said there is something wrong with deine cable?
[01:20:22] <PetefromTn_> to me he looks a lot more like a real agent might look instead of a pretty boy
[01:20:31] <Tom_itx> seems the first ones he wasn't much of a lady's man
[01:20:35] <Tom_itx> that changed
[01:20:37] <Crom> went thru 3 melzi boards on the reprap, then said screw it and stuck a mega2560 and ramps 1.4 in it.. with the 20x4 lcd, and on the K40 laser also stuck a mega2560/ramps 1.4 with graffic lcd
[01:20:53] <malcom2073> yeah the melzi baords are crap
[01:21:03] <malcom2073> ramps is crap too, but at least they don't fry randomly
[01:21:05] <PetefromTn_> so it was good then?
[01:21:17] <Tom_itx> yeah i though so
[01:21:47] <Tom_itx> the intro is in true bond form
[01:22:25] <CaptHindsight> what's a theater ticket cost in Kansas?
[01:22:26] <PetefromTn_> like I said I like Daniel Craig as Bond, I like them all but he seems to be more genuine somehow
[01:22:30] <Crom> malcom2073, true.. already fried 2 A4988 drivers, but it's easy to swap them out
[01:22:38] <Tom_itx> CaptHindsight, afternoon imax was 10
[01:22:42] <malcom2073> Flaky wiring?
[01:22:45] <Tom_itx> 13 regular iirc
[01:22:52] <malcom2073> That'll fry them pretty quick
[01:22:55] <Crom> helper stuck them in backwards
[01:22:55] <Tom_itx> 7 & 10 for normal seats
[01:22:57] <PetefromTn_> man its crazy how they have gone up
[01:23:10] <malcom2073> Heh
[01:23:12] <malcom2073> that'll do it too
[01:23:19] <Tom_itx> we don't go that often
[01:23:20] <PetefromTn_> movies and some popcorn and candy and you are in for over $70

[01:33:59] <zeeshan> i work man :"(
[01:34:00] <zeeshan> no vacation
[01:34:03] <ssi> booooo
[01:34:10] <ssi> yesterday was day 1 of my 22 day weekend :D
[01:34:11] <Tom_itx> zeeshan, get off your arse and git r dun
[01:34:17] <zeeshan> hehe
[01:34:24] <zeeshan> i think the project manager name suits tom
[01:34:29] <ssi> agreed
[01:35:16] <Tom_itx> if i had one to build you wouldn't see me for a while
[01:36:21] <malcom2073> ssi: I won one of the kurt vises
[01:36:49] <ssi> nice :D
[01:36:56] <malcom2073> My dad got one too
[01:37:04] <malcom2073> Mine looks real nice on the machine :)
[01:37:38] <ssi> what size
[01:37:42] <zeeshan> if you got 40 of some stainless parts
[01:37:48] <ssi> D60?
[01:37:49] <zeeshan> that you wanna countersink on the drrill press
[01:37:55] <zeeshan> but theylre only 1" by 1"
[01:37:55] <malcom2073> 6"
[01:37:57] <zeeshan> how do you hold em
[01:37:57] <malcom2073> yeah D 60
[01:38:01] <zeeshan> without cutting your finger
[01:38:17] <ssi> zeeshan: make a fixture plate that they drop into that keeps them from spinning
[01:38:23] <zeeshan> a lotta work
[01:38:24] <zeeshan> :P
[01:38:29] <ssi> wear gloves
[01:38:31] <zeeshan> haha
[01:38:38] <malcom2073> zeeshan: clamp them in a vise
[01:38:40] <ssi> clamp a fence on the table
[01:38:44] <zeeshan> malcom2073: too much work
[01:38:46] <ssi> but then alignment suffers somewhat
[01:38:49] <zeeshan> i think ill do what ssi said
[01:38:50] <malcom2073> So is getting your finger replaced
[01:38:51] <zeeshan> make a small fixture plate
[01:38:55] <zeeshan> i got the program for it already
[01:38:59] <XXCoder> just do it in hand
[01:39:06] <zeeshan> i did one in hand
[01:39:06] <XXCoder> with drill press
[01:39:09] <zeeshan> but it was pretty sketchy
[01:39:19] <XXCoder> it is when parts is small
[01:39:21] <zeeshan> you know when you can anticipate youre about to slice your hand open?
[01:39:25] <zeeshan> i get that feeling when i do it
[01:39:28] <zeeshan> cause iknow itll spin out
[01:39:30] <ssi> heheh
[01:39:35] <malcom2073> Grip it harder
[01:39:42] <malcom2073> Like Bull
[01:39:42] <ssi> the worst is that eternity between when you slice yourself open and when it starts to bleed
[01:39:43] <XXCoder> make a hand thing that clamos on part
[01:39:45] <zeeshan> someone can you please make me a robotic arm
[01:39:49] <zeeshan> so i can do dumb shit like this
[01:39:53] <zeeshan> without taking my own arm out
[01:39:54] <ssi> it doesn't hurt yet, you just look at it going "oh hell, this is going to suck"
[01:39:58] <XXCoder> use the ring clamp and wood rod something
[01:40:00] <zeeshan> hey, maybe i will build one
[01:40:01] <XXCoder> im sure you can figure
[01:40:02] <zeeshan> i think this is a good idea
[01:40:07] <zeeshan> an assistant hand
[01:40:10] <ssi> the other one that sucks is when you weld a bunch of aluminum
[01:40:12] <zeeshan> for the drill press!
[01:40:15] <ssi> then you wait a minute and then pick it up barehanded
[01:40:19] <zeeshan> haha
[01:40:21] <ssi> and it falls out of your hands like it's sippery
[01:40:26] <ssi> which is just your flesh melting off
[01:40:27] <zeeshan> dude my assistant hand would work for that too !
[01:40:28] <Tom_itx> zeeshan, you didn't like my idea on that part?
[01:40:38] <ssi> the first indication you've done something wrong is all of a sudden your skin feels tight
[01:40:38] <zeeshan> which idea
[01:40:38] <Tom_itx> mill it all from the countersink side?
[01:40:43] <ssi> then you get that "uh oh" feeling :)
[01:40:55] <malcom2073> I hate that "How much am I going to regret this tomorrow" feeling
[01:40:55] <zeeshan> i cant Tom_itx
[01:40:58] <Tom_itx> use an undercut mill for the bottom part
[01:40:59] <ssi> osha loves me
[01:41:10] <Tom_itx> you could
[01:41:23] <zeeshan> seriously though
[01:41:27] <Tom_itx> i was
[01:41:28] <zeeshan> think an assistant hand would be a good tool? :D
[01:41:32] <ssi> haha no
[01:41:34] <zeeshan> cmon
[01:41:34] <ssi> it'd be too hard to use
[01:41:36] <malcom2073> Get a vise
[01:41:39] <malcom2073> stick it on a robotic arm
[01:41:40] <malcom2073> boom
[01:41:40] <zeeshan> what if i make it very friendly
[01:41:41] <malcom2073> assistant hand
[01:41:49] <XXCoder> zeeshan: not too friendly lol
[01:41:51] <zeeshan> iwill dedicate time and effort
[01:41:59] <zeeshan> you can even use it to replace a woman
[01:42:05] <XXCoder> seriously make a hand part holder. not robot arm whatever
[01:42:07] <Tom_itx> zeeshan, cut a pocket for the part to fit in and one of those rubber tipped clamps
[01:42:08] <ssi> zeeshan: now you have my attention ;)
[01:42:21] <malcom2073> We got one of these at work:
http://www.rethinkrobotics.com/baxter/
[01:42:23] <Tom_itx> hand clamps
[01:42:34] <zeeshan> see !
[01:42:36] <malcom2073> You grab its hand, show it how to do what you want it to do, and then click" go" and it does it
[01:42:36] <zeeshan> assistant hand!!!!!!11
[01:42:53] <zeeshan> that lcd screen with eyes is a bit freaky though
[01:42:53] <zeeshan> wtf
[01:43:09] <malcom2073> Yep
[01:43:21] <zeeshan> Tom_itx: wont need a clamp
[01:43:29] <zeeshan> cause counter sink wont really pull it up
[01:43:31] <XXCoder> those machnes will replace us
[01:43:39] <malcom2073> XXCoder: Maybe you.....
[01:43:40] <malcom2073> :P
[01:43:59] <malcom2073> As a robotics technician, I'm all for replacing simple jobs with robots, means more jobs for me
[01:44:10] <XXCoder> lol
[01:44:15] <zeeshan> i thought you were a programmer
[01:44:17] <zeeshan> !
[01:44:22] <ssi> malcom2073: agreed
[01:44:26] <malcom2073> I wear many hats
[01:44:31] <malcom2073> Depending on how much people want to pay me
[01:44:34] <ssi> my argument about the minimum wage crap people have been clamoring for
[01:44:36] <XXCoder> makes it hard to enter buildings
[01:44:37] <malcom2073> That job doesn't pay much, so I'm a robotics tech
[01:44:39] <XXCoder> but otherwise cool
[01:44:44] <ssi> forget $15/hr minimum wage, let's go straight for $150/hr
[01:44:52] <ssi> I'll get it
[01:45:00] <ssi> they'll pay me to automate everyone else out of a job :)
[01:45:04] <malcom2073> XXCoder: I just duck
[01:45:08] <XXCoder> lol
[01:45:12] <CaptHindsight> meat robots
[01:45:13] <ssi> I want to start "Ian's Discount Robot Emporium"
[01:45:19] <ssi> "(for all your $15/hr minimum wage needs)"
[01:45:31] <XXCoder> CaptHindsight: once a while I do feel like a meat robot at work lol
[01:45:35] <malcom2073> ssi: Burger makers, and automated oil change robots
[01:45:37] <Tom_itx> zeeshan, cut a U in one end of the pocket so you can easily get them out
[01:45:51] <ssi> malcom2073: yep, all these things are feasible
[01:46:04] <zeeshan> yes
[01:46:05] <ssi> whether or not they're cost-practical depends on the cost of the labor you're trying to replace :)
[01:46:18] <Tom_itx> zeeshan, like i did here:
http://tom-itx.no-ip.biz:81/~webpage/boards/USBTiny_Mkii/Stencils/stencil_form1.jpg
[01:46:20] <malcom2073> Higher the minimum labor rate, the more cost-practical it becomes
[01:46:23] <ssi> exactly
[01:46:27] <CaptHindsight> DMV counter person
[01:46:37] <ssi> CaptHindsight: those jobs will never go away at any price
[01:46:44] <ssi> the government doesn't obey supply/demand curve
[01:46:48] <CaptHindsight> Comcast phone sales and tech support
[01:46:54] <ssi> they've already automated a lot of that
[01:46:56] <Tom_itx> zeeshan, for stenciling these:
http://tom-itx.no-ip.biz:81/~webpage/boards/USBTiny_Mkii/Stencils/stencil_form3.jpg
[01:47:09] <ssi> they have remarkably convincing sounding customer service voice AI now
[01:47:15] <ssi> sometimes it's hard to tell when you're talking to a human or not
[01:47:15] <XXCoder> CaptHindsight: if they did that there would be easy to bypass. just replace tailpipe with fake one that just blows air n(assuming older car)
[01:47:23] <ssi> we were talking about that at work the other day
[01:47:26] <XXCoder> human would notice. robot wont.
[01:47:42] <ssi> surefire robot test: when they start talking and tell you their name
[01:47:44] <XXCoder> just pipe tiny amount from real pipeline so it has small amount of polluants
[01:47:49] <ssi> interrupt them by saying their name loudly
[01:47:54] <ssi> a robot won't notice, a human will geht startled
[01:48:16] * malcom2073 makes a note to have his robots startled at such an occurance
[01:48:21] <ssi> malcom2073: ;)
[01:48:38] <ssi> keep coming up with smarter robots, I'll keep finding better turing tests :)
[01:48:47] <ssi> they call me 'edge case boy' at work
[01:49:16] <malcom2073> That's ok, fortunatly, the majority of the population are idiots
[01:49:20] Tom_itx is now known as project_manager
[01:49:26] <malcom2073> So you really don't have to cater to the edge case
[01:49:35] <malcom2073> just let them wallow in self-realized pity
[01:49:36] <ssi> that's the absolute truth
[01:49:39] project_manager is now known as Tom_itx
[01:49:49] <ssi> Tom_pmp
[01:50:17] <zeeshan> Tom_itx: nice

[01:52:41] <Tom_itx> you can see that in the pic too
[01:53:39] <ssi> CaptHindsight: I have been without the ability to have comcast for the last year
[01:53:53] <ssi> I mostly would rather pay for their miserable customer service and data caps than what I have now
[01:53:59] <ssi> but it's a tough call :)
[01:55:29] <malcom2073> +1 to that
[01:55:38] <malcom2073> but I don't feel like paying $30k for them to run a line to me
[01:55:39] <malcom2073> heh
[01:55:47] <ssi> yeah that's the boat I'm in too
[01:56:05] <malcom2073> I'm 1 mile too far
[01:56:13] <ssi> I'm at an airport
[01:56:16] <malcom2073> Heh
[01:56:20] <malcom2073> you live in that hanger, don't you?
[01:56:23] <ssi> there's cable at the condos at the racetrack across the street
[01:56:28] <ssi> no, I live in a different hangar

[01:57:52] <Jymmm> ssi: Isn't that the local whore house?
[01:58:04] <ssi> CaptHindsight: I've thought about that, I don't know anyone who lives there
[01:58:07] <ssi> they're deserted most of the time
[01:58:09] <malcom2073> Yeah, seems like an odd place to live
[01:58:10] <CEO2015> fancy house heh
[01:58:21] <ssi> Jymmm: god I wish
[01:58:36] <Tom_itx> ssi, quiet neighborhood?

[01:58:47] <CEO2015> ssi: whats up with your house lately?
[01:58:49] <ssi> I mean besides the fact that it's an airport
[01:59:05] <ssi> CEO2015: it's nearly done but I'm not moving back there
[01:59:27] <malcom2073> ohhhh yeah that's right, you had a fire didn't you?

[03:03:31] <ssi> so I have a set of bondhus t-handles, and I love them
[03:03:40] <ssi> I Had a metric set and a standard set, but the metric ones didn't survive the fire
[03:03:48] <_methods> wiha
[03:03:51] <ssi> plus I am missing one out of the standard set, 5/32
[03:04:04] <ssi> rather than replace the set, I discovered I could buy a single wrench off ebay, so I did
[03:04:18] <_methods> get wiha's
[03:04:18] <ssi> but I neglected to note whether it was long/short, or ball end or not
[03:04:26] <malcom2073> Heh oops
[03:04:33] <ssi> my set is long ball end, and the one I bought to replace it is short non-ball :(
[03:04:45] <malcom2073> Could not have gone more wrong eh?
[03:04:50] <ssi> seriously
[03:04:53] <ssi> it's the right size at least :)
[03:04:59] <malcom2073> heh
[03:05:01] <malcom2073> small favors
[03:05:06] <ssi> holy cow the wiha ones are pricey
[03:05:17] <_methods> they're awesome
[03:05:22] <_methods> no other wrenches compare
[03:05:26] <_methods> worth every penny
[03:05:27] <ssi> they better be for $75!
[03:05:55] <ssi> oh here's the current state of my snapon madness

[03:06:29] <_methods> all the wiha tools are nice
[03:06:40] <_methods> spendy but worth it
[03:06:47] <ssi> yeah I have wiha screwdrivers and they're awesome
[03:07:06] <ssi> although I mindlessly used one of my wiha flat blade screwdrivers to stir some molten aluminum :(
[03:07:14] <_methods> doh
[03:07:15] <ssi> tried to use it later and the tip just twisted like caramel
[03:07:49] <ssi> it's funny, you don't even think about the hardness of tools til you get one that's not hardened
[03:08:01] <_methods> lol
[03:08:04] <ssi> I have some harbor freight pin punches that look pretty nice, but if you try to use them they just bend
[03:08:09] <_methods> fisher price screwdriver
[03:08:51] <ssi> the black area in that toolbox drawer is part of that wrench tray, has spots for allen wrenches and I have them laid out in there
[03:08:57] <ssi> it's kinda dumb and inefficient
[03:09:09] <ssi> I think I'm gonna put them back in their plastic holders and just cut the bottom off that tray
[03:09:19] <ssi> tehn I can move the wrenches to the front of the drawer and put 3/8 drive stuff at the back
[03:10:12] <ssi> I need to order a CDI 3/8" 250in/lb torque wrench too
[03:10:47] <_methods> i grabbed one from harbor fright

[03:11:03] <ssi> nah they're not bad, I've used them
[03:11:08] <ssi> but I LOVE the cdi ones

[03:11:34] <ssi> worth it

[03:16:22] <PetefromTn_> really?
[03:16:31] <ssi> probably
[03:16:33] <PetefromTn_> I wonder what the weight limits are
[03:16:40] <ssi> maybe not a weight limit issue so much
[03:16:49] <ssi> but performance is very much a factor of weight in something like that
[03:16:58] <ssi> and they're light enough that pilot weight is a significant portion
[03:17:17] <ssi> being 50lb overweight in a 1500lb airplane is bad, being 50lb overweight in a 150lb airplane is disastrous
[03:17:25] <PetefromTn_> they launch it from feet, from behind another plane, from a car tow etc...

[03:26:15] <_methods> they had a small 5c 4th axis
[03:26:19] <_methods> and an hrt-310
[03:26:35] <_methods> i got burned on the 2 tm-1's
[03:26:45] <PetefromTn_> Why should I go find my own when my old buddy old pal methods offered to find me one damnit!!
[03:26:45] <_methods> guy bought both of them for $8750
[03:26:58] <_methods> so i don't get my mill
[03:27:10] <_methods> boss was going to give me the shops eztrak

[03:33:59] <jesseg> If I have a tilt table, is it named A?
[03:34:10] <ssi> A is rotation about X, so it depends :)
[03:34:44] <jesseg> Ahh. What if it's a tilting rotary table?
[03:34:55] <ssi> https://i.ytimg.com/vi/XMcoJMBTDIQ/hqdefault.jpg
[03:34:59] <ssi> a trunnion table like that?
[03:35:05] <ssi> if it's parallel to X like that, then it's an A
[03:35:06] -!- R2E4_ [R2E4_!~michel@69.70.7.42] has joined #linuxcnc
[03:35:12] <ssi> if it's perpendxicular to X, it's a B
[03:35:41] <jesseg> that's some picture. I honestly can't tell if it's a 2 axis device or not :P
[03:35:46] <ssi> that's not
[03:35:56] <ssi> http://www.cncindexing.com/assets/images/tilt-rotary-table-sh.jpg
[03:35:58] <ssi> you have one like that?
[03:36:02] <ssi> a 4th/5th?
[03:36:30] <ssi> so I get a little fuzzy here, but I believe the 5th is named for its rotation when the 4th is at 0 degrees
[03:36:38] <ssi> so that'd be an A and a C in that case I believe
[03:36:40] <jesseg> yeah that's what I'm asking about. I'm building one from two rotary tables that I'll put servo motors on and mount together
[03:36:50] <ssi> rotation about X is the trunnion, rotation about Z is the rotary
[03:37:15] <jesseg> Until the first axis tilts up 90 degrees :D
[03:37:31] <ssi> yeah but see I don't think that matters, it's still a C
[03:37:39] <ssi> the order that rotations are applied in kinematics is significant
[03:37:41] <_methods> that's why most people just say it's a 4th axis or 5 axis machine
[03:37:47] <jesseg> cool. Thanks!
[03:37:57] <PetefromTn_> https://www.facebook.com/CatDaddy305/videos/10156019733610386/ This is funny
[03:38:06] <_methods> on lathes people get more particluar
[03:38:15] <_methods> is it a c axis lathe or a y axis lathe
[03:38:35] <_methods> but on mills youll normally just say it's a 4 axis mill
[03:38:38] <ssi> well on a lathe, to me C axis means using the spindle for accurate positioning
[03:38:38] <_methods> or 5 axis mill
[03:38:47] <jesseg> So what letter would I use if I had a 4th linear axis?
[03:38:48] <ssi> whereas Y is if you had a vertical slide
[03:39:00] <ssi> jesseg: typically U/V/W
[03:39:04] <ssi> those are parallel to X/Y/Z
[03:39:06] <R2E4_> Whats the basic concept of sending commands from same source to two different joints?
[03:39:38] <jesseg> ssi, ahh thanks! So if I had an axis for the wire feed on a CNC wire feed welder, and the wire fed in the Z axis, then I'd use W, right?
[03:40:00] <ssi> yes, although the orientation of a wire feeder in cartesian space probably isn't significant :)
[03:40:17] <jesseg> True
[03:40:23] <ssi> think more along the lines of a cnc hot wire cutter, where you might have an X/Z on one side and a U/W on the other
[03:40:45] <jesseg> Oh, got it. Actually two X axis, etc.
[03:40:50] <ssi> right
[03:41:07] <ssi> and the cutting tool is a line that extends between those two points in cartesian space separated by the Y distance
[03:41:30] <jesseg> right. I've done manual hot wire and wished for CNC so I know exactly what you're talking about :D

[03:41:55] -!- Tecan [Tecan!~fasdf@unaffiliated/unit41] has joined #linuxcnc
[03:42:02] <ssi> other possibilies might be something like automating a knee mill
[03:42:08] <ssi> you may have Z for quill and W for the knee
[03:42:10] <jesseg> Oh, right.
[03:42:11] <ssi> or vice versa
[03:42:17] <jesseg> exactly
[03:42:43] <ssi> which way you set it up will probably depend on which axis you use for your primary programming
[03:42:55] <ssi> cause linuxcnc handles X/Y/Z in more sophisticated ways than it does UVW
[03:43:08] <jesseg> How is that possible...?
[03:43:20] <ssi> it's minor stuff... we were just talking about it the other day
[03:43:33] <ssi> the only one I'm aware of is the naive cam detection
[03:43:43] <ssi> code that has a lot of moves in W might be slower than code that has a lot of moves in Z
[03:43:59] <ssi> just vagaries of how the trajectory planner works :)
[03:44:09] <jesseg> It's an axis, and it controls a servo.. Why would X control one servo any differently then U controlled another identical servo..?
[03:44:23] <jesseg> oh well doesn't matter to me :D
[03:44:49] <ssi> the control aspect isn't any different, it has to do with detecting multiple segments that are colinear and converting them to one segment
[03:45:01] <jesseg> ahh
[03:45:08] <ssi> which affects how the trajectory planner handles coordinating motion, due to the need to accel and decel into and out of corners
[03:45:17] <jesseg> yeah
[03:45:49] <jesseg> accel/decel in corners makes my brain hurt to think about it :P
[03:46:07] <ssi> well just consider it like you were driving a car
[03:46:18] <ssi> you can't drive arbitrarily fast into a corner and make an instantaneous 90 degree turn
[03:46:18] <jesseg> yeah
[03:46:28] <ssi> requires infinite acceleration to do t hat
[03:46:57] <PetefromTn_> I can in my Van
[03:47:04] <jesseg> but the part that put my brain it knots was trying to figure out how to accel/decel only as much as needed considering the trajectory of the next segment :P
[03:47:10] <ssi> PetefromTn_: only because it doesn't go fast enough to violate its accel limits :)
[03:47:27] <ssi> jesseg: yeah that part gets complex
[03:47:36] <PetefromTn_> Oh she's fast enough for you alright.....what's the cargo?
[03:47:40] <ssi> insert a lot of words here about lookahead and exact path mode vs path tolerance etc
[03:48:16] <ssi> and it's not super significant for milling type work, but it's a big deal for jet cutting
[03:49:09] <jesseg> ssi, yeah for my initial experimental perl script trajectory planner I just had it come a full stop between each segment always. I think I did figure out how to do it right, and someplace I have sketches on paper but I lost that and forgot :P But yeah it involved looking ahead or something
[03:49:35] <ssi> most of this stuff seems simple til you actually try to do it :)
[03:49:41] <jesseg> LOL that's for sure.
[03:50:03] <jesseg> Does jet cutting eat too wide of a hole if you dwell too long?
[03:50:12] <ssi> depends on the process what happens
[03:50:19] <ssi> but for instance, for plasma, one of two things happens
[03:50:43] <jesseg> oh yeah plasma eats out too much and perhaps burns your consumables :P
[03:50:44] <ssi> if you have torch height control, it's trying to maintain the arc voltage, which it does by controlling the arc length via Z height
[03:51:02] <ssi> as you slow down, the voltage will increase, so the torch will dive into the material
[03:51:09] <jesseg> ahh, yeah
[03:51:32] <ssi> if you have advanced features in your thc to lock the height into corners, it works but the cut quality suffers because you're cutting with suboptimal torch height
[03:51:43] <jesseg> yeah
[03:52:04] <ssi> laser can have similar problems, when you slow down you're putting more energy into the cut
[03:52:09] <ssi> but most laser systems run pulse mode
[03:52:20] <jesseg> ahh, so they can match speed
[03:52:21] <ssi> and it's pulses per linear unit, so you get constant energy into the cut
[03:52:36] <ssi> I say most, I don't know if that's true
[03:52:44] <ssi> lots of co2 laser systems work that way, including mine
[03:52:49] <jesseg> cool
[03:53:14] <Praesmeodymium> the popular shitty blue box from china is a CW mode laser
[03:53:38] <ssi> yeah that doesn't surprise me
[03:53:40] <Praesmeodymium> needs a few upgrades for pulse mode
[03:53:49] <ssi> the neat thing about pulsing is you actually get more power out of the tube that way
[03:54:09] <ssi> cause there's a transient spike from the trigger voltage, which falls off to rated power
[03:54:18] <ssi> and if you pulse, you get that transient spike on every pulse

Basically designed and built a PIC micro based 4 channel PID motor controller board, which communicates either via S&D on printer port (works with LinuxCNC) and also works via RS232 which allows up to 4 boards (16 servos) to be controlled in a coordinated manner.

[04:02:27] <ssi> gotcha
[04:02:32] <ssi> are you aware of the mesa stuff?
[04:02:55] <jesseg> So I use that PCB to control my 2.5D engraver and am setting up to use it also for me little Shoptask lathe/mill (LOL ya I know junk but hey..), and my 3D printer design.
[04:03:12] <jesseg> Yeah, I've read about mesa, even struggled with pluto and stuff
[04:03:46] <ssi> I only mention it because it's an existing very well thought out, extensible system for doing hardware motion control, and it's tightly integrated with linuxcnc
[04:03:48] <jesseg> Haven't really kept up with any of that in years though since I had good success with my own system
[04:03:51] <ssi> and it's moderately priced
[04:04:00] <jesseg> yeah it's cool and all
[04:04:08] <ssi> but if your goal is hardware design, carry on :)
[04:04:47] <jesseg> but I like to control my motors via a small low power embeded linux computer, using text based /CLI programs or scripts, and it seems to work really well via the serial port :)
[04:05:07] <ssi> that's basically the same concept
[04:05:13] <ssi> for instance, this is what I'm working on now
[04:05:20] <ssi> https://github.com/rene-dev/stmbl
[04:05:54] <ssi> I'm helping write the code to make it a smartserial remote to work with linuxcnc via mesa hardware
[04:06:13] <jesseg> ahh cool
[04:07:06] <ssi> mesa stuff is basically fpgas that attach to your host via pci or epp or ethernet, and allow you to offload a lot of the lower level and fast-timed work to the fpga
[04:07:16] <ssi> and then give you a lot of hardware options for interfacing with mechatronics
[04:07:29] <jesseg> yeah it's a really neat idea
[04:07:39] <renesis> wow you said mechatronics
[04:07:50] <ssi> renesis: was it the word of the day?
[04:08:03] <renesis> when i say mechatronics everyone goes WHAT THAT
[04:08:15] <renesis> ssi: is the major im studying
[04:08:23] <ssi> ah haha
[04:08:45] <renesis> a lot of times i just say we learn how to design mechatrons
[04:08:48] <jesseg> Sounds like a fun major
[04:08:56] <renesis> its funny when some people just go 'oh'
[04:09:01] <Loetmichel2> meh... about 5 cuts in the fingers later i have about 1/3 of the cardboard boxes my wife has stacked in the living room cut down, ready for disposal... those xacto knives go thru fles like they go thru cardboard: effortles.. :-( *gets another bandaid and affixes it* ... maybe i should have started earlier than 6 hours prior to my wife coming back with cleaning up that mess...
[04:09:01] <ssi> mechatronics as a major always struck me as "I like computers! I like electronics! I like robots! I like mechanical engineering! I have no idea what major to pick!"

[04:09:24] <renesis> jesseg: kinda, its hybrid EE and ME, basically no electives that arent absolutely required
[04:09:53] <ssi> if I were going to school I'd probably do mechatronics actually
[04:10:30] <jesseg> ssi, My major impediment is that I have a hard time figuring out other's code. It's often easier for me to just write my own for simple stuff then to figure out someone else's example code :P
[04:10:38] <ssi> jesseg: I understand entirely
[04:10:41] <ssi> but that way lies madness :)
[04:10:46] <renesis> i want to double major in EE, that way id be like 3/5 electronics and 2/3 mechanical, i think that reflects me
[04:10:53] <ssi> in the software industry we call that "not-invented-here syndrome"
[04:11:32] <ssi> fact of the matter is code is easier to write than it is to read, and it's very easy to be tempted to throw it away and start over
[04:11:42] -!- pcw_home has quit [Remote host closed the connection]
[04:11:43] <ssi> but you're throwing away a lot of years of someone else figuring out bugs
[04:12:08] <jesseg> ssi, yeah, or depending on the project, a lot of years of someone adding buts :P
[04:12:29] <ssi> generally that's not how it works
[04:12:51] <ssi> when you dive into an old code base, the stuff that looks like a bunch of hacky ramshackle garbage is actually the fossil record of years of bug fixing :)
[04:13:09] <jesseg> Thing is, finding someone else's bug is a thousand times harder to my own. So even if someone else's code has 1% as many bugs as mine, fixing tem is still ten times harder when you're a poor programmer like me
[04:13:20] <renesis> thats the job
[04:13:24] <ssi> yep
[04:13:36] <ssi> thats why code is harder to read than to write
[04:13:43] <jesseg> haha yup

[04:13:57] <ssi> past you is a dick
[04:14:07] <renesis> you get hired and tell a project manager 3/4 the way through a project youre just going to rewrite it, youll maybe have no job

[04:34:45] <jesseg> Hmmm. The Journeyman's Guide to Cnc Machines - Bryan Hurst -- says that U,V, and W are relative to X,Y, and Z, regardless G90/G91 mode.. But does say that A/B/C are in degrees and are either incremental or absolute depending on G90/G91
[04:34:50] -!- Tecan has quit [Quit: Live Long And Phosphor!]
[04:35:47] <jesseg> ssi, does it make sense for U/V/W to be relative to X/Y/Z ?
[04:36:16] <ssi> it makes sense to design a system that way, but I'm fairly sure that's not how linuxcnc works
[04:36:25] <ssi> http://linuxcnc.org/docs/html/gcode/machining_center.html
[04:36:29] <ssi> The U, V, and W axes produce linear motion in three mutually orthogonal directions. Typically, X and U are parallel, Y and V are parallel, and Z and W are parallel.
[04:37:07] <jesseg> I'll do it the linuxCNC way then :)

[04:42:20] <ssi> jesseg: so if you're doing this, do me a favor and implement your trajectory planner as a finite-jerk planner. That's one thing we're missing currently
[04:43:05] <jesseg> ssi, haha umm I don't know even what that is. But I did look up the word gullible in the dictionary and there was my picture :D
[04:43:10] <ssi> haha
[04:43:27] <ssi> jerk is the derivative of accel, right
[04:43:32] <XXCoder> hey Jymmm it works, kinda. my really crappy webcom dont work with app but definitely detected
[04:43:36] <ssi> our tp will change accel as a step function
[04:43:49] <ssi> ie it goes from 0 accel to N accel instantaneously
[04:44:01] <ssi> which means that there's infinite jerk at that transient
[04:44:18] <jesseg> I might not be following.
[04:44:18] <Praesmeodymium> does your planner not have junction devation?
[04:44:25] <ssi> a finite jerk planner would have a MAX_JERK param in addition to the MAX_ACCEL that we alraedy have
[04:44:45] <ssi> and it would limit the rate of change of accel into and out of acceleration changes, so as to keep the jerk under MAX_JERK
[04:44:48] <jesseg> It is not possible to go from 0 speed to a non zero speed in the digital world without some infinite ratio of acceleration..
[04:44:56] <jesseg> Ahhhh
[04:45:14] <jesseg> And what unit would MAX_JERK be?
[04:45:25] -!- anth0ny_ has quit [Quit: anth0ny_]
[04:45:25] <ssi> machine units per second per second per second :)
[04:45:32] <ssi> mm/s^3
[04:45:41] <jesseg> Ahh the cubic whine
[04:45:56] -!- choonway has quit [Quit: Leaving]
[04:46:17] <ssi> finite jerk will make flimsy machines less shaky on motion
[04:46:18] <jesseg> So is jerk a problem....? I never really thought about it. I mean, obviously at slow speeds my machine moves in steps of it's hardware encoder resolution
[04:46:35] <ssi> hang on trying to find you a pic
[04:46:39] <jesseg> oh thanks
[04:46:57] <jesseg> I will tell you right up front I'm not too bright and rather slow to understand things :P
[04:47:08] <ssi> https://pbs.twimg.com/media/Btb4wAaIUAAWZYp.jpg:large
[04:47:19] <ssi> that's one of the first tests of my laser
[04:47:22] <jesseg> hahahaha
[04:47:31] <jesseg> I take it he snakies were invaders?
[04:47:39] -!- AR_ has quit [Ping timeout: 240 seconds]
[04:47:48] <ssi> that's due to shaking of the machine due to flimsy legs without enough damping, and infinite jerk motion
[04:48:10] <jesseg> hmm
[04:48:27] <jesseg> so acceleration and deceleration were too quick..?
[04:48:32] <ssi> I only bring it up because if you're dead set on reinventing the wheel, might as well make it a better wheel :)
[04:48:49] <jesseg> yeah! thanks! I appreciate it! I'm dead set. :P
[04:49:03] <jesseg> But I'm not sure I understand the problem.
[04:49:17] <pcw_home> Jerk is an issue because without limited jerk you have steps in forces
[04:49:51] <ssi> you know how when you're stopping your car with constant deceleration, when you come to a stop it's sorta abrupt feeling, and a car with squishy suspension will rock back and forth?
[04:49:55] <ssi> that's jerk
[04:49:57] <pcw_home> these steps contain a wide range or frequencies and can excite vibrations in the mechanics
[04:50:04] <ssi> that's going from some val of decel to zero accel all at once
[04:50:06] <jesseg> ssi Ahhh, OK
[04:50:36] <jesseg> Sudden change in inertial force
[04:50:50] <ssi> something like that :)
[04:50:53] <pcw_home> yes stepwise changes
[04:51:49] <jesseg> ssi, what kind of XY framework did you have? That is significant wobble. It was so bad I thought you had servo resonance issues :P Or is it open loop steppers?
[04:52:13] <ssi> it was steppers, and it was a fairly big machine built out of 20mm extrusion
[04:52:26] <jesseg> ahh LOL okay yeah I found that with my 20mm extrusion project too
[04:52:29] <ssi> the frame was 60x36" plan view
[04:52:37] <ssi> and it sat on 36" tall spindly 20mm legs
[04:52:47] <ssi> and when the gantry would stop, the whole machine would shake fore and aft on the legs
[04:52:58] <ssi> I could have solved the problem by making the machine stiffer and better damped
[04:53:04] <ssi> instead I solved the problem by setting it on fire
[04:53:09] <jesseg> LOL
[04:53:52] <ssi> but that picture is interesting because you're seeing those instantaneous changes in direction I was talking about earlier
[04:53:56] <jesseg> I should take note, because I've started a 1.5Mx1.5M CNC plasma cutter project. Only has a Z axis of 3 inches though, and it sits down only a few inches tall
[04:54:00] <ssi> there's a lot of dynamics in those corners that are important
[04:54:06] -!- dagjomar has quit [Ping timeout: 240 seconds]
[04:54:12] <ssi> I have a machine about that size
[04:54:21] <ssi> 54"x54" plasma cutter with a 2.5" Z
[04:54:26] <ssi> but that machine is much more rigid
[04:54:36] <ssi> it's built out of 2x4" 3/16" wall steel tubing
[04:54:39] -!- MrSunshine has quit [Ping timeout: 240 seconds]
[04:55:28] <jesseg> yeah, come to think of it, to do a perfect corner you do have to come to a complete stop, even if it's only 45 degrees, other wise you have a moment of infinite acceleration on the one axis :P
[04:55:41] <XXCoder> I guess Jymmm left
[04:55:41] <ssi> exactly
[04:56:00] <ssi> the only way to avoid stopping is to radius the corner
[04:56:07] <ssi> how small a radius you can do depends on your max accel
[04:56:27] <XXCoder> ssi: on that im curious how small it would be at 200 m/s
[04:56:31] <XXCoder> er
[04:56:35] <XXCoder> mm/s^2
[04:56:49] <jesseg> Maybe I wont' even worry about trying to maintain any velocity between segments, unless perhaps they are within very close to the same trajectory :P

[04:57:30] <ssi> these problems have already been carefully considered and solved :)
[04:57:32] <jesseg> yeah and it hurts :P

[05:00:00] <jesseg> The problem is I'm not really a real machinist. I'm just a hobbiest. Most of the times I bang my head against the wall in want of CNC, it's for simple things like a rectangular or radial bolt hole pattern, or a simple pocket, or cutting threads, or whatever. So my intention is to actually make little task specific scripts for doing just that. Nothing fancy, just let me do what I want with no muss or fuss if making a 3D design. I'm not very good at 3D des
[05:00:00] <jesseg> ign :P
[05:00:02] <ssi> nice
[05:00:39] <ssi> jesseg: yeah I hear you, but I think your time would be better spent learning to use an existing system rather than trying to climb that ladder all over again
[05:01:17] <jesseg> ssi, oh probably. But this is my entertainment time. I don't watch TV or read news paper. I do this instead. So all it's gotta be is better spent than TV :D
[05:01:28] <ssi> trust me, I'm one of the worst offenders when it comes to stubbornly doing things my way rather than spending money on things
[05:02:36] <ssi> think of linuxcnc as an incredibly powerful programming language for building machines
[05:02:40] <jesseg> In fact I have used LinuxCNC. A friend wanted to get into 3D printing, so we rigged up a little Sherline aluminum mini mill with a hotend and ran it with LinuxCNC via the printer port. So I know what's out there and I've tasted it.
[05:03:09] <ssi> once you learn the language, you can extend it in all sorts of ways
[05:03:14] <jesseg> Yeah, and if I'd written it, I'd be able to make it do whatever I wanted :D
[05:03:18] <ssi> ways that don't require you to rewrite a trajectory planner :)
[05:03:50] <jesseg> My trajectory planner actually works very well for my applications so far :D
[05:04:08] <ssi> there's a learning curve, but it's not nearly as steep as the learning curve for writing a good general purpose machine control platform
[05:04:30] <jesseg> yeah, the learning curve is so steep I fell off
[05:05:53] <jesseg> I even am writing a 2.5D simple cad program because I couldn't stand the user interface on any I've tried :P
http://videoflier.com/gwcad/
[05:06:03] <ssi> hey I'm with you there
[05:06:10] <ssi> I haven't solved the cam problem for myself yet
[05:06:20] <XXCoder> cam too :(
[05:06:28] <ssi> in fact, why don't you write a cam program for us instead
[05:06:30] <XXCoder> freecad I like, pretty effective cad
[05:06:35] <ssi> and I'll help you get running with linuxcnc for your machines :)
[05:06:35] <XXCoder> please
[05:06:40] <ssi> THAT would be a better use of your time :)
[05:06:43] <jesseg> ssi, is cam that step to turn the cad model into GCodes?
[05:06:46] <ssi> yes
[05:07:11] <XXCoder> its apparently easy for 3d printers and not so much for mill and other stuff,
[05:07:43] <jesseg> ssi, ahh. My cad program does export to GCodes. But it's only 2.5D, in that you can draw lines and stuff and you can specify their Z value, and it will be sent, but there is no support for moving Z at same time of X or Y.
[05:08:55] <ssi> these kinds of things get very complicated in the edge cases
[05:09:05] <jesseg> What's an edge case?
[05:09:31] <ssi> situations that exist outside of the mindset you were in when you wrote the software :)
[05:09:40] <XXCoder> yeah

[05:17:28] <XXCoder> it includes equipment table lol
[05:18:18] <jesseg> ssi, thank you for the kind offer. However, 3D math makes my brain hurt seriously. I'm just no good at it. And I've already gotten my machines working with LinuxCNC before, using S&D on LPT. However, I've wondered how hard it would be to get LinuxCNC talking to my PID/Servo driver boards via the Rs232 port, since that allows reading of position and full resolution everything.
[05:18:42] <ssi> jesseg: probably wouldn't be that hard
[05:18:48] <archivist> rs232 is too damned slow
[05:19:10] <ssi> archivist: it's fast enough for a 1khz position loop if you're just sending pos_cmd and receiving pos_fb
[05:19:17] <ssi> I think it is anyway :)
[05:19:27] <archivist> for how many axes!
[05:19:33] <ssi> and RS232 itself isn't slow
[05:19:38] <ssi> smartserial is rs232 :)
[05:19:55] <ssi> (for some values of rs232)
[05:20:01] <archivist> actually real rs232 has speed limits due to the cable

[05:20:33] <jesseg> yeah... my protocol does 960 positions/second for ONE axis, 1/4 of that for four :P
[05:20:42] <ssi> jesseg: yea that's too slow
[05:20:48] <ssi> needs to be about five times faster
[05:21:05] <ssi> if you could do 1000 updates a second for four axes you'd be in the ballpark :)
[05:21:15] <jesseg> ssi, yeah it does, but in my case, the PID is entirely on the motor controller board so the RS232 slowness does not cause delay in the PID
[05:21:30] <ssi> understand that
[05:21:38] <jesseg> My PID loop runs at 1Khz
[05:22:01] <jesseg> so yeah, no high performance operations for me. I just run everything slower :P
[05:22:37] <ssi> archivist: i believe it's pretty trivial to get rs232->rs485 converters and run higher speeds on longer runs
[05:22:44] <jesseg> I could actually use a higher baud rate if my PC supported it (and actually, now days, they do support higher rates a lot of times, like a mbit or more)
[05:23:06] <archivist> ssi two wrongs dont make a right :)
[05:23:14] <jesseg> LOL
[05:23:24] <ssi> jesseg: the drive I showed you earlier runs a 5khz servo loop and communicates over 2.5mbit rs422 ie smartserial
[05:23:34] <jesseg> ssi, oh cool
[05:23:38] <ssi> archivist: three rights make a left :)
[05:23:38] <jesseg> way to go
[05:26:01] <ssi> speaking of which, I really really need to sort out the input scaling code
[05:26:12] <ssi> I've been sitting here ADD'ing out for like four hours
[05:27:32] <jesseg> ssi, I been thinking about your jerk issue. I'm worried that no matter what the exact decel curve looks like, the fact is there's still x mass changing rate over y time, and that will create force. If t he machine is wobbly, it will wobble :P
[05:28:04] <XXCoder> rigidness IS important to machine
[05:28:06] <jesseg> The trick is to get most of the decel time spread out over a time period that is longer than the resonant period of the machine
[05:28:25] <ssi> jesseg: yeah but then you have a sloooooow machine
[05:28:31] <jesseg> so simply increasing the accel/decel length could do it
[05:28:34] <ssi> you want as much accel as you can get
[05:28:40] <jesseg> yeah I know. A wobble machine is a slow machine :P
[05:28:46] <ssi> otherwise you spend all your time accelerating, and never cruising
[05:29:06] <ssi> jerk management could lead to a machine which was smooth AND fast
[05:29:08] <jesseg> If x amount of mass changes y amount of velocity in a time period less than the resonant period of the machine, it's *gonna* sway.
[05:29:14] <XXCoder> ssi: I recently finally found good balance with my machine

[05:34:24] <XXCoder> my guess? do one a time

[05:36:32] <ssi> jesseg: don't give me alternate solutions to the problem just because you don't want to learn how to write a finite jerk tp :)
[05:37:10] <XXCoder> ssi:
https://en.wikipedia.org/wiki/Gyroscope
[05:37:43] <ssi> XXCoder: what am I supposed to get from that?
[05:37:54] <XXCoder> it is basic design
[05:37:59] <XXCoder> video is bit more complex
[05:38:06] <ssi> I know what gyroscopes are
[05:38:27] <jesseg> ssi, well, it's not that I don't want to, it's that I don't think it's possible to change the velocity of a mass quickly without exerting force. The machine has a certain resonant frequency that's pretty low, and if your entire acceleration happens within that time period, you're *gonna* have sway -- unless you are modeling and compensating for machine sway like they are in that tripple pendulum video
[05:39:00] <jesseg> Then you'll still have sway but it won't matter because it's been pre-emphasized out :P
[05:39:29] <ssi> that's not the point of the discussion though
[05:39:34] <ssi> I don't even have the machine anymore
[05:40:02] <ssi> the point is that some modern tps are designed around limited-jerk, and that's one way to make your time meaningful
[05:40:28] <jesseg> Ahhh OK, I'll definitely keep it in mind if I redo my acceleration algo!
[05:40:53] <jesseg> It should be simple, right? Force is a function of acceleration, right?
[05:41:19] <jesseg> Some sort of log accel or something
[05:41:27] <ssi> I don't know
[05:41:29] <ssi> if I knew I'd be doing it :)
[05:42:14] <jesseg> yeah, f=ma where F is force, M is mass, and A is acceleration
[05:42:46] <ssi> yeah, now differentiate that wrt time
[05:43:17] <jesseg> So you just start out with an almost zero acceleration, then your next step's new position needs to be based on an acceleration that creates only a slightly increased force
[05:43:33] <jesseg> such that force is ramped up non-linearly
[05:43:42] <jesseg> What does wrt mean?
[05:43:45] <ssi> with respect to
[05:43:48] <jesseg> ahh
[05:44:44] <jesseg> well, if you know the distance to the next step, and you know the new desired force, you can calculate the needed rate and thus time and position to effect the desired force.
[05:45:06] <ssi> "desired force" isn't something we use, fwiw
[05:45:09] <jesseg> Of course you'll have to do the same thing once max speed is reached -- begin tapering acceleration
[05:45:38] <ssi> I'm pretty sure our stuff is approached the other way around
[05:45:54] <ssi> you know where you are and where you want to be, and you know how fast you want to get there (feed rate or max traverse rate)
[05:46:02] <jesseg> oh but it is. Or should be if you want to avoid jerk. The force that the carriage exerts on the frame is equal to a*m
[05:46:21] <ssi> yes I understand that but that's not how machine integration is typically approached
[05:46:25] <ssi> unless you're zeeshan
[05:46:35] <jesseg> I guess that's why we have jerk ;)
[05:46:55] <ssi> there's more to it than the force
[05:47:01] <jesseg> You probably could fake it with a log lookup or something
[05:47:05] <ssi> you're thinking steady state, but this is a dynamic third-order system
[05:47:11] <jesseg> There's more to jerking than force? hmmmm...
[05:47:19] <ssi> yes, because the machine is reactive
[05:47:41] <ssi> you apply a force, and it's going to absorb some of that energy via damping and reflect some of it via spring
[05:47:47] <ssi> and cause first, second, and third order ringing
[05:48:13] <ssi> so if you want to do it via the math approach, you're going to be doing a lot of third order diffeqs :)
[05:49:18] <jesseg> well, if you mean avoiding a sudden change in acceleration caused force, that's straightforward, but if you're talking about modeling (or measuring) machine deflection and pre-emphasizing for it, then that's a bit more complicated
[05:49:57] <ssi> but I'm not talking about that, you suggested that
[05:49:57] <jesseg> In part, the position of the tool may affect the degree to which machine deflection causes tool position error
[05:50:14] <XXCoder> rememberm it is not GMm/d^2 that kills. it's d^3x/dt^3
[05:50:17] <jesseg> Hmm, okay
[05:50:36] <ssi> I'm merely talking about a tp that changes acceleration continuously, rather than in a step function
[05:50:55] <jesseg> What was tp again?
[05:51:03] <ssi> you know that you can't change position in a step, so we change continuously, that's known as velocity
[05:51:07] <ssi> trajectory planner
[05:51:09] <jesseg> ahh
[05:51:17] <ssi> we know that we can't change velocity in a step, so we change continuously, that's accel
[05:51:49] <ssi> linuxcnc's tp changes accel in a step, and yours should change it continuously, that's jerk
[05:52:02] <ssi> it's the same stuff, just an order deeper
[05:54:10] <jesseg> So in my current tp, basically rate starts out at like 1% and ramps to 100% of speed over .1 inches or whatever it is, I don't remember. It ramps linearly so half way into the acceleration it's going 50% of normal speed.
[05:55:25] <jesseg> What if instead we used the square of the distance from the starting point (scaled to 0-1)
[05:55:51] <ssi> by rate you mean velocity?
[05:56:05] <jesseg> I guess that would create another jerk when it reached speed and suddenly switched to zero acceleration
[05:56:13] <jesseg> yeah inches/minute
[05:56:35] <ssi> yeah so you have a basic linear acceleration
[05:56:37] <XXCoder> unless you flatten again near max
[05:56:50] <ssi> what you need to do is consider the acceleration the same way you consider the velocity
[05:56:51] <jesseg> XXCoder, right, then do the same thing in reverse
[05:56:59] <ssi> and change the rate of accel at the start and end of the accel move
[05:57:01] <ssi> that would be finite jerk
[05:57:28] <ssi> just like you change the rate of velocity at the start and end of the cruise
[05:58:52] <jesseg> I still think that no matter *what* you do, if your full acceleration period fits inside the resonant period of the machine, the machine is *gonna* sway. :D
[05:59:07] <jesseg> but I could be wrong. I've been wrong before and will be wrong in the future :)
[05:59:24] <XXCoder> there is infinite ways to be wrong, and only few right ways.

[06:00:20] -!- anth0ny_ has quit [Client Quit]
[06:00:46] <jesseg> well I guess I still like my idea of calculating instantaneous acceleration based on desired force and current velocity, so that force can be ramped up and down. If you have 3 time/place points you can calculate the force of acceleration, right?

[06:02:45] <ssi> hey give it a shot
[06:03:06] <ssi> just remember that the mass is a pretty big questionmark in most machines :)
[06:03:15] <jesseg> But it's constant.
[06:03:18] <ssi> is it?
[06:03:35] <jesseg> well, I doubt it varies by more than 10% on a 3D printer.
[06:03:40] <jesseg> But what were yo u thinking?
[06:03:54] <ssi> I have a 10,000lb mill fifteen feet from where I'm sitting
[06:03:58] <ssi> every axis moves a different mass
[06:04:04] <ssi> measuring those masses is non-trivial
[06:04:15] <ssi> furthermore, I can put a 400lb block of metal on the table and start slinging it around
[06:04:22] <ssi> and that block gets lighter over the course of a program
[06:04:24] <jesseg> Oh I see
[06:04:33] <ssi> very much non-constant mass :)
[06:04:40] <XXCoder> indeed
[06:04:41] <jesseg> yeah you would need realtime tuning
[06:04:48] <ssi> yeah, and nobody wants that :D
[06:05:07] <ssi> see, there's lots of ways to approach these problems
[06:05:24] <jesseg> well, still, the exact force wouldn't really matter, as long as the change in force was always gradual
[06:05:28] <ssi> there's the hypertheoretical approaches that someone with a bunch of time in a control theory classroom and little time with hands on a machine might take
[06:05:48] <ssi> and there's the difference between the approach someone with 10klb machines might take vs someone with a reprap
[06:06:08] <jesseg> yeah
[06:06:25] <ssi> plus it sounds like you're approaching it from a mindset of "it takes X to control THIS machine"
[06:06:37] <ssi> whereas linuxcnc is written with the mindset of "what could we possibly need to control every machine in existence"
[06:06:53] <ssi> that's a challenging thing to do

[06:09:56] <jesseg> pardon the terrible asymmetric curve. I cannot draw with the mouse. Actually, I cannot draw.
[06:10:12] <ssi> yes that's very possible
[06:11:34] <jesseg> although it may be better to key it off of the *time* from the endpoint, since the distance changes the rate of change (lol) but then coming to the other end may be tricky since you don't know how long it's gonig to take to decel :P
[06:12:03] <jesseg> But, different curves could be developed that worked well - one for accel and the other for decel
[06:13:40] <jesseg> Speaking of taking shortcuts, when I did my PID loop, I was doing it in 8 bit PIC assembly using 32 and 64 bit ints and didn't want to have to divide, so I just ran my loop at exactly 1Khz on a timer and left out the /dt part since dt was always the same :P
[06:16:35] <jesseg> ssi, Ahh, okay I should have been using the term G instead of Force and Mass, since mass is an unkown. We know that 1G is 9.8m/s/s or whatever, but that's besides the point. Anyway, the tp would try accelerate at a maximum of x g/s. Then we don't have to worry about the mass of the table or anything.
[06:18:22] <jesseg> Then the G/S would be ramped up then ramped down when full rate was reached.

[06:28:22] <jesseg> ssi, there. I put a TODO note in my source code to remind me about it for when I work on that in the future :
[06:28:23] <jesseg> :)
[06:28:34] <ssi> excellent :)
[06:28:38] <ssi> report back what you find out
[06:28:57] <jesseg> will do! I put your nick in there too so I'll remember who to report back to :D
[06:33:54] <fenn> you might also look up sinusoidal trajectory planning if going to all this bother to deal with jerk
[06:34:17] <jesseg> I don't even know what that is :)
[06:34:19] <Contract_Pilot> Ok, Reset code's on tranny connector dry hwy speed and kick down no error code!
[06:34:30] <fenn> since a sine function is bounded no matter how many times you take its derivative
[06:35:06] <Contract_Pilot> Think it was water in connector.
[06:35:26] <Contract_Pilot> We did have nearly 2" rain that night.
[06:37:22] <Contract_Pilot> Controller on table tomarrow evening to be rewired for the 7I76
[06:37:42] <Contract_Pilot> then config LCNC then convert to path Pilot.
[06:38:44] <ssi> :D
[06:38:50] <ssi> I'm curious to see how pathpilot treats you
[06:39:49] <ssi> FINALLY got all my scaling stuff working correctly
[06:40:54] <fenn> ssi jesseg this looks to be in the right ballpark
http://www.aspe.net/publications/Spring_2001/01Sp%20Extended%20Abstracts/Arevalo.PDF don't worry about the equations too much just look at the graphs and text
[06:41:16] <jesseg> K
[06:42:08] <fenn> i guess the magic keyword phrase is "sinusoidal velocity profile"
[06:43:31] <Contract_Pilot> Should be Good only thing is the vistaCNC pendant!
[06:43:46] <Contract_Pilot> Intergrating it.
[06:46:11] <Contract_Pilot> All i am awaiting on my compound slide block.
[06:46:18] <jesseg> fenn, yeah that looks like it alright!
[06:46:39] <anomynous> okay. How do I calculate how strong press I need to punch a certain width of cut with a certain tensile strength? Or is that what is needed?
[06:46:50] -!- Tecan [Tecan!~fasdf@unaffiliated/unit41] has joined #linuxcnc
[06:47:00] <jesseg> anomynous, you might need to know sheer strength too, not sure :P
[06:47:12] <XXCoder> shear?
[06:47:21] <fenn> the amount of force depends how much shear angle your punch has
[06:47:25] <jesseg> LOL. Me and spelling met once. Decided to never see eachother again.
[06:47:32] <anomynous> our press is sheer strength. :)
[06:47:42] <Contract_Pilot> VistaCNC pendants support LinuxCNC so should not be to hard to merge it to PathPilot but LCNC has sweet support.
[06:47:44] <ssi> fenn: probably similar to the cutting angle of a lathe tool
[06:48:01] <fenn> probably 0 degrees actually since that's easiest to make
[06:48:02] <Contract_Pilot> Mach sucks!
[06:48:05] <XXCoder> lol jesseg
[06:48:13] <Contract_Pilot> hate mach support!
[06:48:23] <ssi> I mean it probably varies in a similar way as a lathe tool's angle
[06:48:31] <Contract_Pilot> #2 Reason for the switch.
[06:48:32] <fenn> for 0 degrees the force required is the length of the perimeter being punched out times the thickness of the material times the shear strength of the material
[06:48:48] <Contract_Pilot> #1 is the encoder support.
[06:48:58] <ssi> Contract_Pilot: such a basic feature :P
[06:49:31] <Contract_Pilot> #3 is the Turning GUI
[06:49:51] <Contract_Pilot> I want to be able to do barrels!
[06:49:58] <anomynous> fenn, ty. what degree?
[06:50:15] <Contract_Pilot> And thread them with nice threads! b
[06:50:43] <ssi> Contract_Pilot: I've done a bit of that :)
[06:50:47] <Contract_Pilot> Port 2 of 5I25 will be for the mill.
[06:51:01] <anomynous> barrels? With threads? Why?

https://en.wikipedia.org/wiki/Annealing_%28metallurgy%29#Full_anneal
[07:06:04] <anomynous> i just want to remove the bump so forming will happen uniformly and not from weakest point
[07:09:11] <fenn> i am looking at a book about steel alloys and processes and there's no bump in the stress/strain graph, it's just a rounded corner for ductile materials and a sharp corner for brittle materials
[07:09:13] <Contract_Pilot> Why am i locked form the forums? n
[07:09:38] <anomynous> i remember it dissapearing at 400deg but how long do i have to keep to prevent it from immidiately emerging after cooling, and stuff ;D Or do i need to buy newly cold rolled
[07:09:57] <anomynous> well the thing that not so much alloyed steels have ;D
[07:11:30] <fenn> is this a result of work hardening?
[07:11:35] <anomynous> aging
[07:13:13] <fenn> hmm "At this point the cross- sectional area of the material starts decreasing and the stress decreases

[07:35:50] <ssi> nothing's legal in md
[07:36:40] <Contract_Pilot> ssi is correct!@
[07:36:41] <Wolf_Mill> yeah, got some fucked up laws here thanks to O'Mally
[07:37:13] <Wolf_Mill> but I think AR in pistol form are still legal (hows that for making sense)

[07:41:33] <ssi> wtf am I doing wrong here :(
[07:41:46] <Contract_Pilot> SSI need to be a Ferry pilot!
[07:41:55] <ssi> maybe
[07:42:01] <Contract_Pilot> Well not now!
[07:42:06] <ssi> not now?
[07:42:22] <Contract_Pilot> nope 1,500 hour rule killed it.
[07:42:30] <ssi> how so
[07:42:52] <Contract_Pilot> I would charge 10k-15k for a flight now pilots are paying 3-5k to fly to build hours.
[07:42:57] <ssi> ahh
[07:43:06] <Contract_Pilot> Gov reg killed it!
[07:43:12] <ssi> like everything else
[07:43:22] <Contract_Pilot> Yep!
[07:43:42] <Contract_Pilot> but accident and death rate is up 200%
[07:43:51] <ssi> on ferry flights?
[07:43:54] <ssi> certainly not in general
[07:44:32] <Contract_Pilot> 300 hour pilot crossing the pond 30% over gross no instruction = bad
[07:44:42] <Contract_Pilot> on ferry flights
[07:44:43] <ssi> yeah that's my thought as well
[07:44:51] <ssi> but whatever, let them weed themselves out of the pool
[07:45:05] <Contract_Pilot> I started at 250 but had a mentor!

[07:45:48] <ssi> 200hp/side instead of 160, 198 gal usable
[07:45:52] <ssi> they built it for atlantic crossings
[07:46:16] <ssi> I'm approaching 1500hrs now
[07:46:19] <ssi> probably 1350 now I think?
[07:46:24] <ssi> I haven't caught up my logs in awhile
[07:46:36] <ssi> but I don't even have my damn commercial :/
[07:46:36] <jesseg> What does the Z.1 mean in the line "N108 G43 H1 Z.1 M8" ? Is it just setting Z, or does it have a special meaning since it's a tool length offset command?
[07:46:41] <ssi> I've been trying to get it done this year

[07:48:23] <Contract_Pilot> About 3,000 hours maybe more my flight records are a mess.
[07:48:35] <ssi> as soon as the comanche is back up, gonna go get my checkride done for my C-ASEL-IA, and then gonna do an addon in another friend's apache and get my C-AMEL-IA knocked out

[07:58:54] <ssi> Wolf_Mill: jesus really? that's asinine
[07:59:04] <Wolf_Mill> yup lol
[07:59:47] <Wolf_Mill> NFA stuff is easy here oddly, even w/out a trust, state police will sign off with no issues
[08:04:28] <Contract_Pilot> on a trust?
[08:06:25] <Wolf_Mill> trust doesnt need CLEO signoff
[08:07:08] <Wolf_Mill> if I remember right

[08:09:34] <Contract_Pilot> Wally world here is plenty but price is high
[08:09:46] <Contract_Pilot> not selling
[08:10:17] <Wolf_Mill> around here it doesnt even last long enough for them to put the price on teh shelf
[08:10:29] <Contract_Pilot> 50.00 for 525
[08:10:50] <Contract_Pilot> Yea, maybe 20.00 35max
[08:11:08] <Wolf_Mill> I really should F1 a can for the AR and just shoot that in the backyard
[08:11:20] <Wolf_Mill> least I can reload 5.56
[08:11:38] <Contract_Pilot> Wait till hearing protection passes next year
[08:12:00] <Contract_Pilot> no need to F1 a Can make a lamp post1
[08:12:21] <Wolf_Mill> that would be nice
[08:12:33] <Contract_Pilot> It will pass.

[08:31:35] <anomynous> why does everyone have a gun
[08:31:39] <anomynous> what do they do with them?
[08:31:59] <Contract_Pilot> Free Syrian Army sorry
[08:32:46] <anomynous> why do americans feel so strongly about guns that its in constitution that people have right to bear them?
[08:32:47] <anomynous> ;D
[08:34:12] <ssi> the bigger question is why do people feel so strongly that they should be able to dictate what things other people are permitted to own :P
[08:34:31] <anomynous> well, crime rates in usa are a question
[08:34:34] <anomynous> safety
[08:34:41] <anomynous> guns dont kill, but people do. and rob and do stuff
[08:34:56] <Contract_Pilot> I had no issues with them even went oun my own sept 2006
[08:34:58] <anomynous> so yeah. i think its reasonable that the majority who do nothing with their guns dont have guns
[08:35:01] <Wolf_Mill> thats cause the mind set of shitstains on the street here
[08:35:11] <Contract_Pilot> in the middle of bombing!
[08:35:30] <ssi> I don't think it's reasonable
[08:35:34] <anomynous> why not?
[08:35:41] <ssi> I'm not sure why what you think is reasonable should trump what I think is reasonable
[08:35:51] <XXCoder> anomynous: numbers of crime is rinsing. but if you compare statatics of population vs crimes, it is decreasing. have been for years.
[08:35:53] -!- shurshur has quit [Remote host closed the connection]
[08:36:09] <Praesmeodymium> my take on why we americans are so big on that right is, the country was founded by revolutionaries who knew they were putting in a nescarry evil that might get out of control, because... humans.... guns would allow the people to rise up and remove the broken thing if required
[08:36:09] <anomynous> ssi, because its not about self. Its about everyone else ;)
[08:36:34] <ssi> sorry but your collectivist nonsense doesn't move me :)
[08:36:42] <anomynous> not my intention
[08:36:52] <anomynous> and why is it nonsense?
[08:37:09] <Wolf_Mill> strict gun laws at work, look at the homicide rates for Baltimore and chicago
[08:37:18] <ssi> consider the fact that I can walk into the next room ten feet from where I'm standing
[08:37:22] <jesseg> The answer to bad guns is not less guns, it's more guns :P (Play on on the line about the answer to bad speech not being less speech but more speech.)
[08:37:29] <ssi> and within it contains all the raw materials and machinery necessary to create a gun from scratch
[08:37:39] <ssi> what exactly is stopping anyone on the planet from owning a gun? certainly not laws
[08:37:46] <Contract_Pilot> only photo of my venture
http://www.stevenrhine.com/wp-content/uploads/2015/11/lebanon.jpg
[08:38:12] <ssi> there was that nonsense a couple years ago about 3d printing guns
[08:38:12] <XXCoder> ssi: then why have laws?
[08:38:13] <anomynous> Wolf_Mill, i dont know about usa. We have quite strict gun laws. Our crime rates are probably lower than yours all around
[08:38:14] <XXCoder> any laws.
[08:38:21] <Praesmeodymium> ssi there still is
[08:38:24] <ssi> and the loonies came out in force to say that we should ban 3d printers because you can make guns with them!
[08:38:30] <ssi> should we ban cnc mills too?
[08:38:36] <ssi> XXCoder: we have laws
[08:38:38] <Contract_Pilot> not us security ditched them easy had a blast !
[08:38:40] <jesseg> ssi, makes more sense for the law to say that EVERYBODY has to carry all the time. Then the lawbreakers would be unarmed :P
[08:38:40] <ssi> it's illegal to murder people
[08:38:46] <ssi> why don't we just enforce that law?
[08:38:47] <XXCoder> ssi: why have laws with cars? crimials murder people with it
[08:38:55] <Contract_Pilot> prob hav 4-5 kids in lebanon!
[08:38:57] <anomynous> ssi, nope. I don't think thats reasonable. Their prime use is not malicious.
[08:39:00] <XXCoder> if ban cars then only criminials will have cars
[08:39:26] <ssi> anomynous: an inanimate object can not have malice or ill intention
[08:39:27] <anomynous> ssi, nor is their possible malicious use a problem. Those who want a gun will probably get one in another way than make it themselv
[08:39:29] <anomynous> themself
[08:39:31] <Wolf_Mill> gun is just a simple machine, kinda hard to blame anything on them
[08:39:33] <Wolf_Mill> IMO
[08:39:34] <anomynous> or some other illegal device
[08:39:42] <anomynous> im not
[08:39:49] <anomynous> blaming guns
[08:39:53] <anomynous> like i said earlier
[08:39:54] <Contract_Pilot> I lived my dearn for sure one off spring 70% of the countries of the plant!
[08:39:58] <ssi> you can make laws against crime
[08:40:08] <anomynous> its just migitating the damage when someone wants to do stuff to other people or their property
[08:40:20] <anomynous> sure you can
[08:40:22] <ssi> laws aganst objects that could potentially be used for crime is like thought-crime
[08:40:24] <Contract_Pilot> my royal oats have been planted!
[08:40:29] <XXCoder> in respect of guns, I just want it be treated like cars. require license and insurance
[08:40:50] <XXCoder> why do cars require it? because cars is dangerous.
[08:40:57] <ssi> XXCoder: incorrect
[08:41:10] <ssi> XXCoder: cars require it because public roads and liability
[08:41:11] <Praesmeodymium> ssi: there ofc exists an illogical extreme that makes sense in the case of illeagle objects

[08:45:05] <jesseg> anomynous, but guns play a very important role in the business of criminals. Do you know what that means? It means they are shooting at innocents!
[08:45:11] <anomynous> i just said that those who dont need them shouldnt
[08:45:12] <XXCoder> ssi: I was never about banning guns. just require license and insurance
[08:45:23] <anomynous> hunting and hobbying are a reason to own a gun, for example
[08:45:29] <Contract_Pilot> I have weppons of all sizes 1lb to 6,000lb

[08:48:04] <ssi> XXCoder: as you should!
[08:48:24] <ssi> I hope people learn how to use their tools before they use them
[08:48:27] <XXCoder> honestly I rather die than have a gun, but I know proper sane way of ownership.
[08:48:30] <anomynous> Wolf_Mill, those statistics dont tell me anything, really
[08:48:31] <ssi> that includes guns, cars, mills, lathes
[08:48:32] <ssi> everything
[08:48:45] <ssi> all those things can kill you if you mishandle them
[08:48:48] <Contract_Pilot> I think the state department said i could show them photos!
[08:48:51] <anomynous> Wolf_Mill, but maybe youre right. There could also be other explaining reasons
[08:49:17] <anomynous> like there is for our lower crime rates compared to yours.... in spite of ridicilously low penalties compared to yours
[08:49:19] <Contract_Pilot> http://www.stevenrhine.com/wp-content/uploads/2015/11/PIC-0009_1-1024x768.jpg
[08:49:32] <fenn> the gun ban was because of the high crime rate, not the other way around
[08:49:34] <XXCoder> ssi: I just read about toddler that shot owner in car. he found gun in car :( bad storage
[08:50:06] <Contract_Pilot> the 3 stell's are mine!
[08:50:31] <Contract_Pilot> bad owner bad edu!
[08:50:44] <Wolf_Mill> XXCoder: thats what you call negligence
[08:51:21] <XXCoder> it is
[08:51:30] <Contract_Pilot> when my son strted smoking pot i took his arms i gave him when hen matures more he will get them back
[08:51:30] <XXCoder> basic training thats all I ask really
[08:51:51] <Wolf_Mill> thats required here too
[08:51:54] <Contract_Pilot> Agree just the basic
[08:51:56] <XXCoder> pot is virtually the most harmless drug there is. in least its not lots achcol
[08:52:12] <Contract_Pilot> but the basics are fround upon in society
[08:52:14] <Wolf_Mill> but inner city banger arent getting guns at the gun store
[08:52:26] <Contract_Pilot> no bb gun fights etc.
[08:52:30] <Wolf_Mill> or getting background checks, or licesne
[08:53:07] <Contract_Pilot> Shit, go to angola and the gangs here are fuccking pussys i laugh at them
[08:53:08] <XXCoder> quite ironically one of loopholes are police themselves. they take guns from criminials and sell em to gun stores, some are shady as hell
[08:53:12] <XXCoder> and guess back its back
[08:53:33] <Wolf_Mill> nope, cant sell them to gun stores
[08:53:33] <Contract_Pilot> angola scarryist plase i have ever been!
[08:53:50] <Praesmeodymium> north portland is the scariest place I been
[08:53:54] <Wolf_Mill> all handguns are regestered in Maryland
[08:54:04] <Praesmeodymium> I am real local lol
[08:54:26] <Contract_Pilot> I have been to 70% of the plant i seek from experiance
[08:54:26] <fenn> portland lol
[08:54:37] <fenn> hobos comin for yer weed
[08:54:37] <XXCoder> I live at tacoma. it used to be fill of many gangs
[08:54:41] <Praesmeodymium> and that wasnt scary, I wasnt there for drugs so no one payed attention to me
[08:54:42] <XXCoder> now theyre largely gone
[08:54:45] <XXCoder> good police work
[08:54:58] <XXCoder> tacoma in 90s wasnt nice place to live
[08:55:08] <Contract_Pilot> no pot town haha
[08:55:19] <Wolf_Mill> baltimore has gone to shit, thats why I live out in the sticks
[08:55:24] <Contract_Pilot> Police here are the problem
[08:55:30] <Wolf_Mill> I use to work in baltimore too...
[08:55:38] <XXCoder> Contract_Pilot: corrupt or thuggish cops?
[08:55:38] <Contract_Pilot> they are a gang them self!
[08:55:43] <XXCoder> cops full of murder?
[08:56:00] <archivist> they kill 6 year olds
[08:56:10] <Praesmeodymium> they are the enforcers of the status quo.
[08:56:25] <XXCoder> archivist: some areas police culture have gone bad
[08:56:33] <Contract_Pilot> here they just use the excuse to get to the next level!
[08:56:42] <XXCoder> I'd fire every police and get few cops in from other cities
[08:56:44] <Praesmeodymium> like loiusiana... operation broken shield
[08:56:51] <XXCoder> then train new cops to full staff
[08:57:33] <Wolf_Mill> part of the problem is most cops dont want to work in the shit areas
[08:57:41] <XXCoder> poticitians are like diapers, they need to be changed sometimes, for pretty much same reason. maybe its same for cops.

[09:16:49] <jesseg> archivist, hmmm. I still don't see how the offset or radius is set. Maybe the gcode file doesn't know but the meachine knows by other means.
[09:17:47] <Contract_Pilot> k i an out
[09:17:49] <archivist> jesseg, erm in the first paragraph "The D word is optional; if there is no D word the radius of the currently loaded tool will be used (if no tool is loaded and no D word is given, a radius of 0 will be used)."
[09:18:14] <jesseg> archivist, yeah but how does the machine know the radius of the tool??
[09:18:30] <archivist> you filled the tool table
[09:18:30] <jesseg> Is that stored in the gcode file someplace? or another file?
[09:18:53] <jesseg> Oh, when you fill the tool table you fill in a form telling the machine who's where.

[09:19:20] <XXCoder> linuxcnc gui for tools is bit awkward

[09:20:45] <jesseg> Ahhh, the tool table is a different file. Got it. Thanks!
[09:21:09] <XXCoder> archivist: so can have seperate files for different programs and so on>

[09:21:43] <XXCoder> Wolf_Mill: I need to add mine but control stuff didnt have any case till today. today it now has nice cardboard case
[09:21:55] <Wolf_Mill> lol
[09:21:57] <XXCoder> I really to make better one later
[09:22:03] <archivist> currently the tool table does not know about horizontal type tooling in a mill
[09:22:40] <archivist> eg gear cutters
[09:23:21] <Wolf_Mill> I'll probably only do length off sets with the table and let my cam handle the rest
[09:24:07] <archivist> does cam even know dear cutters!
[09:24:12] <archivist> gear
[09:24:24] <archivist> http://www.archivist.info/cnc/target.php
[09:24:33] <Wolf_Mill> guess it depends on the cam soft...
[09:24:55] <archivist> inside rear of skull cam
[09:26:27] <archivist> also the tool table has no room for hobs

[10:39:51] <chuckbob> Well, haven't had the greatest luck with this tuning
[10:39:59] <chuckbob> http://i.imgur.com/eGHfzDk.jpg
[10:40:07] <chuckbob> this is where I am now, any suggestions?
[10:41:27] <anomynous> what are you doing and why do you have such an awesome looking cnc oscilloscope? ;D
[10:42:33] <chuckbob> i know... This is on a benchtop mill.. AMC 30a8 brushed amplifiers
[10:43:07] <anomynous> i know what?
[10:43:20] <awallin> do you have some smart order of doing things, for getting P, I, D, FF1, FF2 ?
[10:43:26] <chuckbob> the cnc oscilloscope...
[10:43:27] <anomynous> ive only seen oscilloscopes that are separate boxes :)
[10:43:38] <anomynous> and i have no clue what that graph is
[10:43:44] <chuckbob> this is a picture from my phone wih halscope
[10:43:54] <chuckbob> Not really awallin...
[10:44:10] <chuckbob> I have tried numerous things
[10:44:21] <awallin> take the wayback machine to 2008 and look at my graphs:
http://www.anderswallin.net/2008/04/x-axis-test/
[10:44:39] <awallin> that was with pico PWM amps and a mesa card.
[10:45:43] <awallin> others should have similar example plots lying around somewhere.. if you can find them..
[10:46:51] <chuckbob> so, starting with P only, everything else at 0
[10:49:54] <awallin> yeah I have a feeling if you can get FF1 and FF2 working well first then the PID has less work to do...
[10:50:22] <awallin> ofcourse you need to have reasonal settings for max velocity, acceleration, jerk also on the trajectory generation side.
[10:50:30] <awallin> can't ask the poor machine to do unreasonable things..
[10:51:08] <chuckbob> this is using a mesa 4i65, same as the 5i20 just a pci-104
[10:51:44] <awallin> ok. my amps are "voltage mode" so the PWM output by thw mesa is more or less the voltage produced over the servos.
[10:51:54] <awallin> current mode or torque mode might be different to tune
[10:52:07] <chuckbob> i can set these in voltage mode
[10:52:34] <chuckbob> was actually trying to tune them that way originally
[10:52:36] <awallin> well in theory measuring corrent/torque and controlling that might be better..
[10:54:11] <awallin> do you have tach feedback to the drive? might make a difference... or just encoder feedback to the mesa?
[10:54:24] <chuckbob> just encoder back to the mesa
[10:54:56] <awallin> ok, velocity mode on the drive might not work that great then. I would try in either current or voltage mode.

[10:56:41] <chuckbob> so, setting everything to 0 except D, raise the value and try to jog?
[10:57:20] <chuckbob> i had increased the D all the way to 100 and the servo whined, without any stiffness
[10:57:41] <ssi> yea I don't really know, I haven't tuned current mode before

[11:25:30] -!- morbo has quit [Ping timeout: 260 seconds]
[11:25:44] <awallin> ok
[11:32:13] <anomynous> its basically making dynamic toolpaths. Cams can either can either control engagement angle or feed rate to migitate for Q or heat increase in inturns. Volumill reduces feed based on cutter and how steep of a curve it is doing.
[11:32:26] <anomynous> dunno if they do something else
[11:32:28] <anomynous> ;D

[11:58:24] <anomynous> you can disable the micro liftoff
[11:58:30] <anomynous> make it 0

[12:03:42] <ssi> what does the code for that look like?

[12:03:57] <rob_h> but u have 1 program file which is realy nice
[12:04:12] <ssi> do you need synchronization between them?
[12:04:27] <rob_h> control sorts it out, just have 0 as program start like normal in it... and have wait codes for sync moves,, on Mitsbuishi its !l
[12:04:33] <rob_h> on fanuc its come M code
[12:04:59] <ssi> oh so you can sync points in the code, but it doesnt' synchronize motion between them
[12:05:22] <rob_h> there are Gcodes which makes axis slaves and masters so can moves together. which just offsets one axis Z to the other so can you can pickup and machine realy realy with no crazy programming or offsets etc like some lathes

[12:06:35] <archivist> we need to broow those codes for linuxcnc
[12:06:44] <rob_h> the old fanuc 6 we had , that was two controls and had to change between them to setup etc.. was a right pain
[12:06:55] <archivist> although some hal trickery could be used
[12:07:03] <rob_h> look on mail list, when someone saida bout multi control/sync i put a quick reply there
[12:07:09] <rob_h> and a Gcode file exsample
[12:07:38] <ssi> archivist: I wonder if we could do something similar by having two full instances of motion running in two separate sets of threads
[12:07:50] <rob_h> thats all you need
[12:07:52] <ssi> and provide some means to synchronize points in the code or slave axes like he's saying
[12:08:01] <ssi> it might be doable but it'd probably take some monkeywork in the core
[12:08:06] <rob_h> then just have 1 motion wait when it sees the wait codes
[12:08:07] <archivist> ssi you need to be swapping about mid run
[12:08:21] <ssi> sure
[12:08:26] <rob_h> you can have !l and just syncs and waits.. or you canname them like !l1 !l2 etc
[12:08:36] <rob_h> as some citizens now have 3 or 4 programs running together
[12:08:44] <ssi> hahah
[12:09:00] <archivist> mine has "gang" tooling too
[12:09:03] <rob_h> or if you realy posh and have a nakamura 4 axis well
[12:09:16] <rob_h> 4 turret i should say
[12:09:29] <archivist> in that two tools are on a rocker
[12:10:13] <archivist> mine shall wait till I get some funds and work for it
[12:11:42] <rob_h> i wish i could change to linuxcnc then i could intergrate the farfeed properly too

[12:12:07] <rob_h> here you go, a sample citizen program
http://pastebin.com/rcbu8mVa
[12:12:51] <rob_h> just a simple turning job, face drilling with sub spindle/slide, and pickup and debur
[12:13:54] <ssi> I see, so it has two file pointers and seeks the second one up to the $2 and runs them concurrently
[12:14:08] <ssi> and uses the !L as "wait for the other thread to catch up" markers
[12:14:20] <rob_h> u got it
[12:14:27] <ssi> that's pretty straightforward
[12:14:40] <rob_h> $3 is a program setup bit. sets bar size, tool plattern layout type etc
[12:15:18] <rob_h> also part length so sets main Z offset correct . also how many parts to make per chucking cycle
[12:15:52] <rob_h> $0 i mean not $3
[12:16:24] <archivist> reminds me of the discussion of infinite cycles on the mailing list last few days
[12:16:38] <rob_h> but you are not limited to only programing Z and X to the main program for main X Z.. u can command X2 Z2 from main $1 or $2 can command Z1 X1 etc
[12:17:09] <ssi> hm but how?
[12:17:16] <rob_h> which makes it abit harder in linuxcnc, i found i only command the other axis set from $1 if i am drilling etc as its easy to keep track in the programs
[12:17:17] <ssi> Z1 is indistinguishable from Z1 :)
[12:19:12] <rob_h> guess you could say it is two controls in 1.. and paramiters say which "axis numbers" are what letters & to which control so can call them what ever you like
[12:19:57] <archivist> thinking of my machine I could be roughing on one too and finishing on another, only one Z needed just a minor Z offset on the tools and finish one a bit later
[12:21:23] <rob_h> yep
[12:23:42] <archivist> I can think of a way to write merged code but I dont think it would be pretty
[12:24:11] <rob_h> ud end up with alot of paused code points and tool dewells i think
[12:25:12] <archivist> hoping the trajectory planner merges the moves nicely

[12:29:37] <rob_h> i think if someone smart could just make linuxcnc run dual or multi motion & trajectory planners u would solve 90% of the it
[12:30:22] <rob_h> as i do see a lot of dual turret lathes etc for sale now days 2nd hand cheap just need a control change as getting on abit but still good machins other wise

[14:18:58] <PetefromTn_> morning zeeshan and everyone
[14:19:10] <anomynous> zeeshan, just push with your spot drill at short intervalls for the text you want to engrave ;D
[14:19:15] <anomynous> maybe that would work
[14:19:17] <anomynous> never tried
[14:19:18] <anomynous> ;D
[14:19:22] <zeeshan> actually thats not a bad idea
[14:19:29] <zeeshan> because a really strong engraving bit looks like that
[14:19:44] <zeeshan> http://www.2linc.com/engraving_tools_tough_tip.htm
[14:19:51] <Tom_itx> won't come out as good as an engraving bit
[14:19:55] <anomynous> with spindle off ;D
[14:19:57] <PetefromTn_> you can just sand and brush finish those if they are not wrong otherwise
[14:20:00] <anomynous> no deburr?
[14:20:18] <zeeshan> thats his job
[14:20:19] <zeeshan> not mine
[14:20:22] * zeeshan doesnt finish here :d
[14:20:39] <zeeshan> im just the mill monkey
[14:20:47] <PetefromTn_> jeez those prices suck
[14:20:55] <zeeshan> yea dude
[14:21:00] <zeeshan> but if it can say do this entire job
[14:21:03] <zeeshan> it woulda been worth it..
[14:21:03] <PetefromTn_> and you got the hairy hands to prove it ;)
[14:21:04] <archivist> cnnx, looks rather flimsy
[14:21:09] <zeeshan> haha PetefromTn_ yes
[14:21:17] <Tom_itx> zeeshan, what happened to the left one?
[14:21:29] <zeeshan> haha
[14:21:35] <zeeshan> you pay too close attention
[14:21:39] <Tom_itx> setup part?
[14:21:42] <PetefromTn_> I noticed it too
[14:21:43] <zeeshan> yes
[14:21:45] <archivist> cockup part
[14:21:48] <zeeshan> offset was wrong
[14:22:05] <PetefromTn_> can't say you had too much tool stickout LOL
[14:22:06] <Tom_itx> just tell him a little putty will fix it
[14:22:17] <anomynous> its the test piece, duh
[14:22:33] <zeeshan> always a good idea for a test piece
[14:22:36] <Tom_itx> anom, that was pretty well understood
[14:22:37] <zeeshan> we're all human :P
[14:22:50] <zeeshan> i screwed that up by lining the tool with the old engraved line
[14:22:56] <PetefromTn_> except tom tom is not human
[14:22:57] <zeeshan> but in reality the origin was at the bottom of the part
[14:22:58] <Tom_itx> no, you're a monkey
[14:23:44] <zeeshan> how would you hold these on a surface grinder?
[14:23:47] <zeeshan> double sided tape?
[14:23:51] <zeeshan> cause they're not magnetic
[14:24:01] <Tom_itx> that or glue

[14:24:13] <PetefromTn_> I would just hit them with an inline sander ;)
[14:24:17] <zeeshan> hehe
[14:24:29] <Tom_itx> vibra tumbler and you're done
[14:24:31] <PetefromTn_> hey it works good
[14:24:39] <zeeshan> i was asking pete but i didnt get a response i think
[14:24:43] <zeeshan> do you have a tumbler?!?
[14:24:46] <zeeshan> i think thats the next tool i want
[14:24:51] <PetefromTn_> no no tumbler here
[14:25:02] <zeeshan> apparently you can load up fine side
[14:25:07] <PetefromTn_> I have looked at some commercial designs to try to build one
[14:25:09] <zeeshan> and tumble this stuf into an awesome finish
[14:25:19] <Tom_itx> it all depends on the media
[14:25:29] <Tom_itx> and how long you leave it in
[14:25:51] <Tom_itx> comes out with a nice finish though
[14:25:58] <PetefromTn_> damn things are very expensive
[14:26:06] <zeeshan> could you not build one easily?
[14:26:12] <zeeshan> its a motor with an offset weight?
[14:26:16] <PetefromTn_> yeah there are several buildable designs
[14:26:19] <Tom_itx> you could but why?
[14:26:19] <anomynous> PetefromTn_, what are?
[14:26:28] <zeeshan> Tom_itx: the cheap ones seem to be small
[14:26:30] <PetefromTn_> what are what?
[14:26:36] <Tom_itx> zeeshan, yeah tabletop
[14:26:36] <zeeshan> id want at least like a 24x24x24" capacity
[14:26:47] <archivist> see also barrel polisher too
[14:26:49] <PetefromTn_> yup tiny ones seem useless to me
[14:26:55] <Tom_itx> my bud started with one of those then got a free standing one
[14:27:02] <Tom_itx> about 3' wide
[14:27:04] <anomynous> a tumbler. Buy a concrete mixer and tumble there? ;D
[14:27:13] <Tom_itx> not the same
[14:27:16] <PetefromTn_> its been done
[14:27:27] <Tom_itx> oh i'm sure it has
[14:27:27] <anomynous> coat with some sprayable gum or something ;D
[14:27:27] <archivist> the noise, the noise
[14:27:28] <PetefromTn_> I saw a guy weld in some auger plated on one
[14:27:34] <anomynous> coat it ;D
[14:27:49] <PetefromTn_> I would imagine any coating would not last too long
[14:27:57] <anomynous> on the outside?
[14:28:09] <anomynous> and if inside coating is sprayable, it is easily replenished
[14:28:11] <Tom_itx> just stuff it in a room by itself
[14:28:19] <PetefromTn_> oh you mean soudnd deadening coating
[14:28:22] <anomynous> that too
[14:28:23] <anomynous> ;D
[14:28:55] <Tom_itx> just don't forget about it or you may go back and find no parts
[14:29:11] <zeeshan> i think you'd want the barrel to be plastic
[14:29:14] <anomynous> you will find perfect bearing balls, only theyre soft
[14:29:18] <anomynous> a good prank?
[14:29:19] <anomynous> ;D
[14:29:21] <zeeshan> for some reason im thinking it'd wear less
[14:29:26] <archivist> we had wooden oned at the clockworks
[14:29:33] <zeeshan> maybe not ;P
[14:29:53] <archivist> they used to break rather than wear
[14:29:53] <PetefromTn_> I saw a guy build one from a 5 gallon bucket and some motor driven rollers
[14:30:01] <PetefromTn_> probably a POS tho
[14:30:03] <zeeshan> haha
[14:30:34] <Sync> doesn't have to be PetefromTn_
[14:30:49] <Sync> ime vibratory tumblers don't work in small scales
[14:31:15] <Wolf_> seen a bunch of 5gal bucket tumblers for pin tumbling ammo casings for reloading
[14:31:52] <Sync> the important thing is to have a soft wall coating and for best results not round walls
[14:32:00] <Sync> so that the medium is carried up
[14:32:05] <PetefromTn_> http://www.risingsunwholesale.com/images/tumbler2.jpg
[14:32:31] <Tom_itx> do you need one that big?
[14:32:38] <Tom_itx> remember you gotta fill it with media
[14:32:42] <PetefromTn_> if you are gonna build one why not?
[14:32:46] <zeeshan> boss
[14:32:50] <Tom_itx> remember you gotta fill it with media
[14:32:53] <zeeshan> could even go in it for a roud
[14:32:55] <zeeshan> ride
[14:32:59] <PetefromTn_> and a 55 gallon drum would hold some large parts '_
[14:33:20] <PetefromTn_> cheap too
[14:33:29] <PetefromTn_> and you could weld to the inside
[14:33:40] <zeeshan> you know you could do the tumbling electronically
[14:33:47] <zeeshan> instead of leaving the motor on constantly
[14:33:50] <Wolf_> then all you need is 30-40gallons of media
[14:34:17] <PetefromTn_> LIKE A BOSS
[14:34:19] <zeeshan> give it different profiles
[14:34:22] <PetefromTn_> :D
[14:34:26] <anomynous> if you could source tumbling and use blasting instead ;D whats the thing called. When they blast some flammable gas to burn the burrs
[14:34:26] -!- morbo has quit [Remote host closed the connection]
[14:34:46] <PetefromTn_> I bead blast in my shop built cabinet a lot of parts too
[14:34:46] <zeeshan> anomynous: that is a cool process
[14:34:47] <zeeshan> :D
[14:35:12] <Tom_itx> media shape affects the results as well
[14:35:19] <zeeshan> yes project manager
[14:35:21] <Tom_itx> and grit
[14:35:27] <Tom_itx> oh piss off monkey
[14:35:29] <zeeshan> haha
[14:35:47] <zeeshan> i dont mind being called a monkey
[14:35:50] <zeeshan> suitable nickname for me
[14:35:57] <PetefromTn_> have you done anything to your lathe yet!!!!!
[14:36:03] <zeeshan> yes, i looked at it
[14:36:07] <Sync> zeeshan: you don't really need to stop the motor, just adjust the speed properly so that the parts don't get lifted
[14:36:14] <zeeshan> and gave it a bit of cleaning :P
[14:36:14] <Tom_itx> pete the project manager
[14:36:35] <PetefromTn_> hey I've been called worse
[14:36:48] <Tom_itx> well we all probably have :D
[14:37:58] <PetefromTn_> honestly while it would take a lot of media that 55 gallon drum type looks like a good idea to me
[14:38:14] <PetefromTn_> if you don't like how big it is you could always cut it in half or 3/4 or whatever
[14:38:22] <zeeshan> you could easily throw some manifold flanges in there
[14:38:28] <Tom_itx> are you gonna roll it or shake it?
[14:38:33] <PetefromTn_> but it is a relatively thick walled very round tube you can get pretty cheap
[14:38:49] <PetefromTn_> I would think roll it
[14:38:49] <Tom_itx> get some plastic drums
[14:38:53] <Tom_itx> they'd last longer
[14:38:57] <zeeshan> roll it at different speeds
[14:39:21] <Tom_itx> even 20 gal drums
[14:39:40] <PetefromTn_> beer keg
[14:39:43] <zeeshan> possible waveform v vs t /\/\___________/-------------------\_______/-----------\_________
[14:40:03] <zeeshan> i'd think as long as you dont keep it constant
[14:40:09] <zeeshan> you'd be forcing the media to mix
[14:40:28] <Tom_itx> you want a spray bar or such inside
[14:40:45] <PetefromTn_> woohoo my 24v 24p mini ITX power supply has shipped ;)
[14:40:56] <PetefromTn_> we'll see how long it takes to get here now
[14:41:07] <Tom_itx> what did you end up getting?
[14:41:10] <pcw_home> chuckbob: if you are tuning voltage or current mode drives you can usually get better performance by raising the servo thread frequency
[14:41:11] <PetefromTn_> that should be simple
[14:41:30] <PetefromTn_> that one we looked at

[14:43:17] <zeeshan> i hope it doesnt pick up radiation on its way here :P
[14:43:37] <Tom_itx> anomynous, would the introduction of gas affect the metalurgy?
[14:43:43] <PetefromTn_> naah the radiation is already here
[14:44:18] <zeeshan> i should get a dosimeter
[14:44:20] <zeeshan> im curious
[14:44:35] <anomynous> Tom_itx, dunno. You are asking the wrong guy, but i dont think so ;D
[14:44:38] <anomynous> im just a machinist
[14:44:50] <Tom_itx> they say test the part
[14:45:08] <Tom_itx> for changes
[14:45:28] <Tom_itx> but they should be minimal

[15:02:07] <Sync> hm, actually I still need your help zeeshan
[15:02:38] <zeeshan> :D
[15:02:46] <Sync> I'm not sure if it is right to assume an exhaust system can be modelled as a helmholtz resonator
[15:02:48] <archivist> I need his Mikron
[15:02:49] <PetefromTn_> to be honest this is the ONLY place I have found online where there are people who really understand retrofits and are willing to share the information
[15:03:18] <Sync> as I'm trying to make sense out of the dyno data with different length headers and piping
[15:03:25] <zeeshan> are you modeling for noise
[15:03:28] <PetefromTn_> at least that are not MACH3 fanboys
[15:04:19] <Sync> no, trying to figure out maximum flow at which frequency
[15:05:03] <PetefromTn_> zeeshan speaking of flow ;)
[15:05:28] <PetefromTn_> Zack showed me a couple pictures of some drag racer guys Rotary iron porting jobs
[15:05:31] <PetefromTn_> JEEEZ
[15:05:39] <PetefromTn_> those guys are nutz
[15:05:58] <archivist> Sync, reminds me of a book I have Performance tuning in theory and practice, four strokes A. Graham Bell Haynes Publishing Group, 1983
[15:06:19] <archivist> iirc that has a section on exhaust
[15:07:07] <zeeshan> Sync: i've only used helmholtz resonance for noise analysis in class. you use the equivalent length, volume, cross section area of neck and speed of sound in a gas
[15:07:12] <zeeshan> to get the frequency of resonance
[15:07:13] <archivist> getting a negative pressure wave back at the right time to scavange the cylinder
[15:07:20] <zeeshan> but im not sure if that resonant frequency relates to flow somehow
[15:07:22] <zeeshan> prolly does
[15:07:33] <Sync> well
[15:07:35] <zeeshan> it prolly is the frequency of flow
[15:07:43] <Sync> my idea is, you have the end of the pipe
[15:07:44] <zeeshan> PetefromTn_: haha they can get serious
[15:07:52] <Sync> going into the larger volume
[15:08:24] <Sync> which is the same as in an helmholtz resonator
[15:08:53] <zeeshan> the pipe should be continuous
[15:09:05] <Sync> so I can tune the volume of the header to the combiner
[15:09:13] <zeeshan> the cavity should be intersecting with the main pipe

[15:09:55] <zeeshan> thats cool
[15:10:02] <Sync> yeah
[15:10:10] <Sync> that's if you want to cut down noise
[15:10:21] <Sync> but I'm not so sure if you can model the entire thing like one

[17:23:39] <andypugh> I think that it sounds like you should try to irradiate your frame during curing. Any increase in E is good.
[17:24:47] <Sync> especially a ~3 fold one
[17:25:00] <CaptHindsight> yeah, just making fun..... it also seems that they don't involved an experienced polymer chemist when doing the research on the blends
[17:25:44] <Sync> I also wonder why they chose such strange filler blends
[17:26:33] <Sync> I heard that you really need to match them on their size and amount so that you can run extremely low binder percentages and get very high mineral factor

[18:57:02] <andypugh> Does anyone do glue sniffing any more?
[18:57:55] <R2E4> Hi guys
[18:59:24] <R2E4> andypugh: When using two motors on Y axis, not doing gantrykins or gentrivkins, not worried about the homing, Do I need to use two seperate pids?
[18:59:47] <andypugh> Servo?
[18:59:51] <R2E4> yes
[18:59:58] <R2E4> 7i77
[18:59:58] <andypugh> Yes
[19:00:19] <andypugh> You definitely need two PIDs.
[19:00:58] <andypugh> Ideally, and if possible, you would tune them one at a time, on the gantry, with the other mechanically disconnected.
[19:01:34] <R2E4> let the slave deal with its feedback and have the first joint sned the pos-cmd to the Aout?
[19:01:41] <R2E4> to both Aout
[19:01:56] <R2E4> IS that the basic concept?
[19:02:20] <CaptHindsight> SpeedEvil: sniff or snort?
[19:02:20] <andypugh> But you can probably start with a bare-motor tuning on both then set the f-error to something not crazy-big and cautiously tune them, but keeping them identical.
[19:02:39] <andypugh> R2E4: Yes, two PIDs fed from the same position-cmd.
[19:03:21] <andypugh> axis.0.motor-position-cmd => pid.0.command pid.3.command
[19:03:35] <SpeedEvil> Be careful with the tuning. Or you can end up with two motor puree.
[19:03:51] <andypugh> So, but get the same command, but both use their own feedback.
[19:04:09] <andypugh> (both get the same command, I meant to type)
[19:04:46] -!- morbo has quit [Read error: Connection reset by peer]
[19:05:07] <R2E4> yeah ok, I was trying it last night but I couldnt get it right because it is not tuned and I was just trying to get the two to behave with the same command.

[19:05:34] <R2E4> one would constantly turn until the the ferror
[19:08:07] <andypugh> Are you clear on how it connects now? one command, two pids, two aouts, a separate feedback for each pid, but only one feedback to motion for f-errror.
[19:09:25] <ssi> might be wise to bring both feedbacks in and somehow wire them via abs and max so that motion sees the larger of the ferrors
[19:09:32] <andypugh> If you want to get clever (and there is something to be said for this), you would sum the abs value of the pid-error term then add that to the motion.command and send the sum to motion.feedback. Then either motor can trigger an f-error
[19:09:36] <R2E4> I understand the concept, and almost had it last night.

[19:37:40] <SpeedEvil> Last week a Russian rocket called Proton-M exploded over a spaceport in Kazakhstan just seconds after it launched. Turns out, we can blame some dumb humans for the blast—investigators found that the rocket's angular velocity sensors had been installed upside down.
[19:38:22] <Sync> it is a stupid design
[19:38:28] <ssi> haha
[19:38:31] <Sync> you design those things that it cannot happen
[19:38:43] <chuckbob_> Should probably get some us digital units

[19:39:27] <SpeedEvil> https://en.wikipedia.org/wiki/NOAA-19#Damage_during_manufacture
[19:39:37] <ssi> chuckbob_: that axis is usable as is, but you could spend some more time with it and get that ferror peak out if you so choose

[19:39:42] <andypugh> The phrase is “Poka Yoke”, design things so that they _can’t_ be assembled wrong.
https://en.wikipedia.org/wiki/Poka-yoke
[19:39:47] <ssi> I'd say leave it, tune the other axes, and get the machine moving first
[19:39:50] <ssi> you can go back and tweak it later
[19:40:14] <chuckbob_> I got the other 2 axis tuned to look almost exactly like that
[19:40:21] <chuckbob_> Less error on the z
[19:41:09] <chuckbob_> Just have to wire up the vfd still and interface it with the 7i33
[19:41:18] <ssi> you just need to balance your desire to get better repeatability against your desire to throw the thing out the window because you're frustrated and tired of tuning :)
[19:41:32] <chuckbob_> Haha
[19:41:36] <ssi> 0.0002" repeatability is pretty good for a hobby desktop mill
[19:42:07] <chuckbob_> Its a taig with servos and a 1hp 24000rpm spindle
[19:42:21] <MrSunshine> hmm, why does americans use the thick disk in angle grinders to cut metal with?! (the like 5 - 6mm or something) ... seen alot of people on youtube do that :P
[19:42:28] <chuckbob_> Not enough machine to be messing with really
[19:42:37] <ssi> MrSunshine: what exactly does it have to do with nationality?
[19:42:55] <MrSunshine> ssi: cause its americans ive seen do it .. no one else =)
[19:43:07] <ssi> the rest of the world uses a hacksaw I guess
[19:43:23] <chuckbob_> I use a fiberglass wheel
[19:43:31] <ssi> anyway, despite the jingoistic bs, the answer is probably "because that's what comes on the angle grinder"

[19:45:36] <MrSunshine> so might be true what you juse said =)
[19:46:21] <ssi> maybe because only in america can non-professional metalworkers afford to go out and buy an angle grinder and a video camera and internet and a computer and make a video showing their lack of experience with their new angle grinder and put it on the internet for you to be critical of?
[19:46:53] <MrSunshine> ssi: haha ... might also be true :P
[19:47:19] <andypugh> No, they can afford all that in the UK too. But we are just more naturally talented with machine tools :-)

[19:50:09] <MrSunshine> oh the grinding scare crow =)
[19:50:10] <MrSunshine> i like it =)
[19:50:23] <MrSunshine> always wanted more than one grinder but im stuck with one until i make more money =)
[19:50:42] <jdh> perhaps if you were more talented.
[19:50:43] <anomynous> more than one grinder?
[19:50:45] <ssi> that's funny, I have at least a dozen grinders
[19:50:53] <anomynous> what kind of a grinder
[19:50:54] <ssi> must be because I'm american
[19:50:59] <Sync> I have several cheap ones and two good ones
[19:51:38] <MrSunshine> a grinder costs like 10% of a month salery ...
[19:51:38] <anomynous> doesnt just one do it?
[19:51:42] <MrSunshine> if its anything to have
[19:51:52] <MrSunshine> anomynous: annoting to change disk =)
[19:52:07] <jdh> a grinder that cost 10% of a month's salary woudl be one impressive grinder.
[19:52:19] <andypugh> My dad, before he retired, occasionally found himself taking a couple of mm of of the working face of a ball-mill drive gear using a bunch of angle grinders. You need a bunch, as they need to cool down during 8 hours of continuous use.
[19:52:21] <MrSunshine> jdh: correction ... not a crap grinder
[19:52:23] <ssi> jdh: my surface grinder was about 10% of a months salary
[19:52:24] <anomynous> i use one so little. Changing it takes maybe 10 seconds
[19:52:26] <anomynous> anyway
[19:52:50] <duc> I used to have 3 but use the plasma instead of cut off disk but down to 4.5 and 7 in hrinder
[19:53:08] <Sync> MrSunshine: my cheap 39€ grinders are fine
[19:53:13] <duc> I hate cut off wheels
[19:53:28] <ssi> I just bought a sioux air angle grinder, it's extremely nice
[19:53:48] <MrSunshine> Sync: the cheapest ive had costs like 60£ and that one is CRAP
[19:53:58] <MrSunshine> sounds like the bearings are done for from the packet
[19:54:07] <jdh> how much do grinders cost in your world?
[19:54:10] <Sync> sure, but they live quite long
[19:54:49] <MrSunshine> jdh: a good one about 170 - 290$
[19:55:44] <MrSunshine> a real good one seems to run like 450$ =)
[19:55:55] <anomynous> which is a real good one?
[19:56:31] <anomynous> and why is it so much more expensive? If its good, then buy that and keep it in good shape? ;D

[20:13:01] <PetefromTn_> its SO complicated that I needed ZEESHAN to do it ;)
[20:13:10] <Duc> Question for the group. Current setup is 5i25/7i76/7i84 for stepper motors but I will switching to analog servo drivers with AC servos. What would be the recommended changes to the setup to receive in 3 encoder outputs and 3 10+/- outputs to control the servos
[20:13:30] <PetefromTn_> 7i77
[20:13:33] <malcom2073> You need a 7i77
[20:13:39] <malcom2073> Bah pete is faster
[20:13:50] <PetefromTn_> :D
[20:13:53] <Duc> Would like to keep the 7i76 to drive the stepper motor on the Knee
[20:13:58] <malcom2073> Yeah the 7i77 allow for controlling up to 6 (I think?) servos
[20:14:28] <malcom2073> How many daughter cards can a 5i25 handle?
[20:14:45] <chuckbob_> I dont have an encoder on the spindle
[20:15:12] <Duc> would a 7i44 (Eight Channel RS-422/485 interface/ RJ45 Breakout) tie all the cards together?

[20:25:17] <chuckbob_> 7i48 wont work with a 5i25 will it?
[20:26:21] <Duc> I think your right
[20:26:24] <chuckbob_> I have a 7i48 and have used it with a 5i20
[20:27:09] <chuckbob_> I actually need to get rid of them.. Was a test setup that wasnt used

[20:27:37] <Sync> why not?
[20:27:40] <Duc> Not sure If I can fit another card in the pci right now
[20:27:53] <Sync> it is vg68, it should not have too many issues
[20:27:56] <malcom2073> Dunno, don't know the first thing about lubricating the machine :P. Seems #2 is the choice for ways though
[20:28:06] <malcom2073> Ok for ballscrews too?
[20:28:16] <chuckbob_> What would you keep the 5i25 for?
[20:28:23] <Sync> I use vg68 for ballscrews aswell
[20:28:37] <chuckbob_> Stepper. I see now..
[20:29:55] <Duc> yea I hate to give up that ability since I will have 3 extra steppers and 3 gecko 203v drivers
[20:30:10] <Sync> sell them ;)
[20:30:40] <chuckbob_> I got so many things i should be selling... Couldnt decide on what i wanted..
[20:31:01] <chuckbob_> Have many ab ultra3000 units
[20:31:10] <Duc> I should sell them. Not sure anyone wants old ass bridgeport steppers

[20:31:35] <malcom2073> chuckbob_: You should, there's a multi-week backlog for buying mesa from the mfg
[20:31:39] <malcom2073> can probably sell them quick on ebay

[20:45:18] <malcom2073> Plus, it sat outside for a year anyway, it looks pretty ratty
[20:45:22] <malcom2073> probably need to pull it apart and clean it up
[20:45:25] <Duc> ebay?
[20:45:43] <malcom2073> Nah it was on the mill I bought off a local guy
[20:47:28] <Duc> I think china makes a rip off bijur pump
[20:47:51] <malcom2073> I'm sure the pump is fine, probably just needs cleaning up. May need new tubes though
[20:48:42] <andypugh> duc: You can connect the 7i77 to the second 25-pin header on the 5i25
[20:50:51] <Duc> andypugh: thanks. That will make it easier. Can the 7i76 or 7i77 be controlled by the serial interface
[20:51:39] <andypugh> chuckbob: There is a specific HAL component for the WJ200, but the man page is a bit sparse. Look in the .comp source file for more info
[20:52:59] <andypugh> duc: Parts of both are serial interfaced, so with the right bitfile it might be possible. The bits that aren’t are the stepgens, encoders and PWM.
[20:54:02] <andypugh> You can sort of figure that out by looking at which terminals on the 7i76 and 7i77 don’t have a matching pin on the DB25 connector
[20:55:16] <Duc> andypugh: In the future I will need to install another 7i84 in my control panel for rotary switches but the 7i76 or 7i77 only includes 1 serial interface at this time. If i remove the 7i76, then Im down to 1 serial interface and not sure out I could place another 7i84 card in the system. Hope that makes sense
[20:56:32] <chuckbob_> Any idea if the 7i29 has a split 50 conductor cable to run two at the same time?
[20:56:33] <andypugh> You can have 7i76 + 7i84 on the DB25 and then a 7i77 and second 7i84 on the second header.
[20:57:14] <ssi> Duc: so what do you need exactly? three servos and one stepper?
[20:57:17] <Sync> malcom2073: don't be so sure

[20:57:26] <Sync> if you oil often, a lot will go through
[20:58:00] <Duc> ssi: I will probably just get rid of all the stepper stuff. Just sounds like a boon doggle and purchase another servo driver
[20:58:08] <ssi> yeah that's probably wise
[20:58:22] <ssi> I'd just hate to waste all those unused stepper and servo interface lines on a 7i76 AND a 7i77
[20:58:29] <ssi> love the control panel btw :)
[20:58:42] <andypugh> chuckbob: You can just connect both 7i29s to a single (3-plug) cable. There is a jumper to tell the 7i29 which lines to pay attention to.
[20:58:48] <ssi> I've always wanted to build a nice panel but havent gotten around to it

[21:01:20] <Duc> andypugh: can the 7i44 work on the 25 pin header on the 5i25?
[21:01:25] <andypugh> chuckbob: you can buy the cable and squeeze the plugs on with a vice.
[21:01:36] <chuckbob_> Thought so
[21:01:55] <chuckbob_> Has anyone here used a 7i29?
[21:02:17] <chuckbob_> Seems to be several pico amps, just curious
[21:02:40] <andypugh> duc: No, not the 7i44, you need the 7i74
[21:03:23] <andypugh> (Actually, you could use the 7i44 but the wiring isn’t convenient)
[21:03:34] <Duc> in which way
[21:03:46] <Duc> I would need to adjust the pinout to make it work?

[21:04:58] <andypugh> The 26-pin header suits a standard parallel-port back-panel adaptor, then a DB25 cable can connect to the 7i44.
[21:05:17] <andypugh> Sorry, 7i74
[21:05:42] <andypugh> The 7i44 needs a 50-pin ribbon cable connector.
[21:05:48] <Duc> andypugh: does the serial interface work like a star network or ring? COuld i take the serial out put from the 7i77 => 7i44 then use the ports to connect to other serial cards?
[21:06:09] <malcom2073> Sync: ?
[21:06:12] <andypugh> You need to add a GND between each signal pin, it’s just not worth the trouble.
[21:06:21] <ssi> Duc: no, it doesn't work th at way
[21:06:29] <Duc> dam
[21:06:30] <malcom2073> I actually am out in the garage now, took off the back panel of the mill and peeked inside, looks like the auto-oiler is dripping oil from the broken tube

[21:06:42] <malcom2073> So I may just be able to get more tube, and see if oil gets everytwhere it's supposed to
[21:06:44] <ssi> I thought I read something about smartserial having the ability to have multiple remotes on one line, but I'm not sure that's accurate

[21:09:51] <Duc> what brand of mill?
[21:10:18] <malcom2073> Clausing Kondia
[21:10:28] <malcom2073> it's an old CNC Knee mill
[21:11:47] <andypugh> malcom2073: You can get push-fit extremely easily
[21:13:53] <Duc> andypugh: 5i25 flat ribbon to adapter then DB25 cable to 7i84 to get additonal serial ports
[21:13:58] <Duc> ?
[21:15:34] <malcom2073> andypugh: Yeah but where in the USA for metric? Ebay may be my only option
[21:16:09] <malcom2073> Hmm, wonder if pneumatic ones would work
[21:16:50] <andypugh> That’s what I was meaning, and I think 4mm is standard in the US too.
[21:16:58] <PetefromTn_> my new maritool facemill made pretty short work of bringing down the 7" wide plate to 6.125" plate on the parts I am making....Coolbeans

[21:20:12] <ssi> JT-Shop: thanks :)
[21:20:27] <Duc> andypugh: sorry typo meant 7i74 not 7i84
[21:20:52] <andypugh> duc: Yes, that works, but you then have to choose between 7i77 and 7i76
[21:21:41] <andypugh> Though for a singlr stepper motor you might want to look at whether it would run fast enough at 500Hz from a softwae stepgen running through GPIO
[21:21:45] <Duc> Ill just be going with 7i77 at that point. expanded serial ports is better

[21:31:27] <zeeshan> man this one customer ive been dealing with is super picky
[21:31:33] <PetefromTn_> I mean everybody and their brother's mother has an aloris
[21:31:42] <zeeshan> i know he'll want 20 more of these parts in another 1.5 months
[21:31:47] <zeeshan> jacking up the price.
[21:31:49] <PetefromTn_> zeeshan WIN
[21:31:55] <andypugh> I just ordered a bunch of holders from:

[21:31:59] <zeeshan> you knwo when you make a fixture for doing their work
[21:32:06] <zeeshan> you know right away you've got the customer for a while :P
[21:32:14] <zeeshan> cause they'll have to pay that fixture cost again
[21:32:22] <PetefromTn_> zeeshan yeah baby you OWN that guy now LOL
[21:32:33] <PetefromTn_> andypugh what do you think of them?
[21:32:40] <andypugh> PetefromTn_: I don’t particularly like Aloris, web research seems to indicate that Multifix is much more repeatable, which is useful on a CNC
[21:32:46] <zeeshan> pete: he was complaning about the normal facing marks
[21:32:54] <zeeshan> i can see reflection of text and read it, thats how good the finish it
[21:32:59] <zeeshan> he was expecting a completely plain finish..
[21:33:04] <PetefromTn_> bastard
[21:33:07] <PetefromTn_> :D
[21:33:15] <andypugh> PetefromTn_: So far, the price seemed reaonable, but as they haven’t arrived I know nothing more,
[21:33:28] <zeeshan> i'd just run a china one if its temporary
[21:33:29] <PetefromTn_> LOL
[21:33:31] <zeeshan> the wedge style
[21:33:47] <andypugh> (I oredered some unlisted blank toolholders, just the spline and adjuster, no tool slot, for a specific application)
[21:33:50] <PetefromTn_> naah If I get an aloris type I will try to get a genuine article
[21:34:14] <PetefromTn_> andypugh I have looked at those and they certainly LOOK nice
[21:34:34] <PetefromTn_> but are they rigid and what sort of holders are available
[21:34:36] <zeeshan> andypugh: if you have 2 materials. aluminum fixed to steel. assume its perfectly fixed
[21:34:36] <ssi> PetefromTn_: build a turret!
[21:34:52] <zeeshan> how would the stress strain diagram look like relative to if you were to test steel and aluminum by themselves
[21:34:55] <ssi> PetefromTn_:

[21:35:00] <PetefromTn_> ssi That is the next step AFTER I get the damn thing working
[21:35:30] <ssi> if I ever build a turret toolchanger for a lathe, I'll make it take hardinge turrets :P
[21:35:35] <ssi> since I already have a couple :)
[21:35:44] <zeeshan> why would turretes be hydraulic on industrial lathes?

[21:36:06] <ssi> I dunno
[21:36:08] <andypugh> zeeshan: Tell me what you see and I will think of a plausible explanation, but I can’t decide just by thinking about it.
[21:36:29] <PetefromTn_> that one that your pals at microkinetics sells looks decent enough but I dunno
[21:36:40] <andypugh> You are going to get a wierd stress-state at the interface. Different bulk module, wierd contraints.
[21:37:00] <ssi> big lathes are waaaaay more complicated than big mills, lul
[21:37:07] <zeeshan> ssi i agree
[21:37:15] <zeeshan> i think its cause of the drawbar stuff
[21:37:19] <zeeshan> and hydraulic tail stock
[21:37:20] <ssi> cause lots of reasons
[21:37:33] <zeeshan> but other than that, i think its ok
[21:37:37] <ssi> multiple spindles, many many many axes, live tooling, independent crossslides
[21:37:47] <zeeshan> okay thats if you get a crazy one
[21:37:50] <zeeshan> w/ sub spindle :P
[21:37:54] <zeeshan> then youre talking 2 turrets!
[21:37:54] <PetefromTn_> mines dirt simple :D
[21:38:07] <ssi> did you see the stuff we were talking about this morning about citizen machines and multipath programming?

[21:38:31] <zeeshan> :-)
[21:38:32] <zeeshan> haha
[21:38:32] <zeeshan> jk
[21:38:33] <andypugh> All the internet discussions I found about “what is the best toolpost” ended up with the Multifix owners triumphant.
[21:38:48] <PetefromTn_> andypugh lemme know how you get along with that multifix toolpost
[21:39:04] <PetefromTn_> why do you say that?
[21:39:37] <ssi> https://www.youtube.com/watch?v=edJYIarO4R0
[21:39:43] <andypugh> I have the toolpost already, and some holders. From eBay. But I think create-tool were the source.
[21:39:46] <ssi> I'm noticing it looks like all their live tooling spins at the same time
[21:39:50] <ssi> is that common?
[21:40:04] <malcom2073> Most of them that I've seen have been like that
[21:40:10] <malcom2073> all the live tooling on a single drive I guess?
[21:40:13] <ssi> I have no idea how they run those live tools in a turret liek that.... air powered? electric with slip couplings?
[21:40:21] <ssi> are the live tools synchronized to motion?
[21:40:30] <malcom2073> Do they ever do a full 360?
[21:40:33] <andypugh> Argh! I can’t abide to see flat-sided gears in graphics.
[21:40:35] <malcom2073> Maybe just coiled wire
[21:40:38] <ssi> I dunno, my hardinge does

[21:45:48] <andypugh> I wonder how many G-code “threads” it runs?
[21:46:10] <andypugh> Ah, they just said “5 channel, 11 axis”
[21:46:55] <ssi> I guess 5 channel means 5 simulateous paths?
[21:47:15] <ssi> would make sense, they have the three compound slides plus the turret plus the subspindle
[21:47:25] <andypugh> That’s my guess. It may be that any channel can use any axis, but not at the same time as another channel.
[21:47:35] <ssi> yea I dunno
[21:48:12] <andypugh> That sounds like a nice big project for LinuxCNC :-)
[21:48:26] <ssi> we were talking about it last night (or this morning maybe? my schedule is messed up)
[21:48:42] <ssi> it could be feasible to run multiple instances of motion and have some minor synchronization between them
[21:48:52] <andypugh> Yes.
[21:48:56] <ssi> the citizen code has multiple paths in it, $1 starts the first path, $2 starts the second
[21:49:10] <ssi> and then !L are sync points, each path will stop until they all getc there then they'll continue
[21:49:21] <andypugh> Sounds sensible.
[21:49:28] <andypugh> And actually do-able.
[21:49:37] <ssi> but the citizen can command path 1's axes and vice verlsa

[21:56:22] <zeeshan> im basically testing 2 diff polymers
[21:56:50] <zeeshan> trying to see if the data makes sense. p v strain makes sense cause, if you had one film that took an x load, and another film that took y load
[21:56:58] <zeeshan> then if you combined them, you would expect them to take x+y load
[21:57:35] <JT-Shop> I need to make a rebar pin puller for my farm jack
[21:59:20] <zeeshan> confused about the stress-strain curve :p
[22:00:49] <PetefromTn_> I'm trying to figure out what advantage the multifix toolpost has over the aloris type
[22:01:14] <zeeshan> im thinking of it as having 2 springs, one really soft, another really stiff. if you fix them together and subject them a load, then i think you would get a stiffness inbetween the two extremes
[22:01:39] <zeeshan> PetefromTn_: looks like its got more teeth
[22:01:41] <zeeshan> for contact
[22:01:55] <andypugh> PetefromTn_: better tool-tip repeatability

[22:04:14] <andypugh> Are they exactly the same shape and thickness? If not, what would be different if they were forcing each other to be the same shape?
[22:04:23] <zeeshan> 0.008" vs 0.005"
[22:04:32] <zeeshan> exact same shape and thickness yes
[22:04:39] <zeeshan> not thickness i mean
[22:04:55] <zeeshan> i did a test of the same material
[22:04:59] <zeeshan> bonded and not bonded
[22:05:04] <zeeshan> and boy are the results very different
[22:05:08] <andypugh> Are they the exact same shape and thickness half-way through the test, was my question
[22:05:16] <zeeshan> yes

[22:07:56] <zeeshan> here is the result
[22:08:08] <zeeshan> notice how different the bonded result is
[22:08:42] <zeeshan> the pressure vs strain result makes sense for single layer. if you multiple the single layer p vs strain curve by 2, you get the double layer w/o adhesive
[22:08:49] <zeeshan> but the w/ adhesive gets crazy.
[22:09:05] <zeeshan> starts showing a 3 stage curve
[22:09:18] <andypugh> zeeshan: Well, the glue is part of the system, did you use that special light inextensible masless glue?
[22:09:44] <zeeshan> yes but why does the glue mean the 2 layers can handle less load
[22:09:47] <zeeshan> that doesnt make sense to me at all
[22:09:54] <zeeshan> vs 2 free standing layers
[22:10:08] <andypugh> There are thickness effects.
[22:10:23] <zeeshan> so youre sayiuung by bonding them
[22:10:26] <zeeshan> you localize the strain
[22:10:32] <andypugh> I seem to remember mentioning that mild steel become brittle when very thick
[22:10:43] <zeeshan> yes you did
[22:11:05] <andypugh> I am saying know this to be true, but I have forgotten why.
[22:12:04] <zeeshan> ill look up papers on laminates
[22:12:06] <zeeshan> im sure this is expected
[22:12:18] <zeeshan> maybe they can give an equation for it
[22:13:33] <Jymmm> Loetmichel: TY
[22:13:57] <andypugh> I can’t properly interpret your graphs because the dot styles in the key section all look the same
[22:14:16] <zeeshan> its circles square and upside triangle!
[22:14:23] <zeeshan> bastards always told me not to use color
[22:14:26] <zeeshan> annoying.
[22:14:30] <andypugh> (unless I make my window bigger, which I just did..)
[22:15:06] <PetefromTn_> I must say that the ability to index that multifix is very nice
[22:15:24] <PetefromTn_> but one thing that I see right away that kinda sucks
[22:15:49] <PetefromTn_> is that if you intend to ever make your own holders for it you have a bunch more difficulty making them than the aloris would be
[22:16:01] <ssi> PetefromTn_: I'll tell you this, for CNC work I really prefer a fixed toolpost that can't rotate
[22:16:10] <zeeshan> PetefromTn_: but theyre cheap to buy
[22:16:10] <zeeshan> :D
[22:16:17] <PetefromTn_> not really
[22:16:23] <andypugh> PetefromTn_: Yes, granted. Folk have done it, and you can buy spline-only blanks for $32
[22:16:27] <PetefromTn_> like 60 bucks each for the simple ones
[22:16:29] <ssi> my g0602 has a phase 2 qctp on it, and it's set up with a shoulder in the base so t he tp is always square to the machine in the same place
[22:16:30] <zeeshan> o
[22:16:38] <ssi> I control tool angle with holder geometry
[22:16:47] <andypugh> PetefromTn_: Which size are you looking at?
[22:16:53] <PetefromTn_> probably B
[22:16:54] <zeeshan> for what its worth, my piston style tool holder held .0015~
[22:17:11] <PetefromTn_> I would probably get a wedge style if I got the aloris
[22:17:12] <zeeshan> what!!
[22:17:14] <zeeshan> you need a ca!
[22:17:14] <zeeshan> :D
[22:17:15] <ssi> zeeshan: yea that's about what the phase 2 piston on the g0602 does
[22:17:29] <ssi> PetefromTn_: are you going to have a compound?
[22:17:38] <ssi> it probably never had one did it

[22:17:39] <zeeshan> i hope he says
[22:17:40] <zeeshan> HELL NO
[22:17:42] <zeeshan> :D
[22:17:52] <ssi> that was an issue on the grizzly too, I had to make a riser block to replace the compound
[22:17:59] <PetefromTn_> it has a massive block that used to hold whatever toolpost it came with
[22:18:02] <ssi> but that height is important
[22:18:16] <ssi> the riser block and the tool post and the size of tools you intend to use
[22:18:21] <ssi> all need to be in agreement
[22:18:31] <ssi> it's tricky to know what to get when you're looking at numbers trying to order it

[22:19:46] <andypugh> The prices do go up fast with size, but that’s true of all QCTPs
[22:19:51] <zeeshan> will it be cast aluminum?
[22:19:57] <andypugh> Cast iron
[22:20:03] <PetefromTn_> I must say he has some rather massive boring bars in those holders ;D
[22:20:04] <zeeshan> you can cast cast iron?
[22:20:07] <andypugh> (not cast by me)
[22:20:16] <zeeshan> outta curiousity
[22:20:18] <zeeshan> how much would it cost
[22:20:22] <malcom2073> andypugh: What is that, some kind of a pulley cover?
[22:20:23] <ssi> how much iron could a cast iron cast if a cast iron could cast iron?
[22:20:31] <zeeshan> lol ssi
[22:20:46] <zeeshan> i see sharp corners :D
[22:21:05] <andypugh> zeeshan: I expect those two parts to be £20 each. The big box was quoted at £80 but I am expecting £120
[22:21:14] <zeeshan> not bad!
[22:21:19] <zeeshan> you make the mold? or they do it
[22:21:37] <andypugh> They make the mould and decide on runners and risers.
[22:21:39] <ssi> molds are ephemeral
[22:21:49] <ssi> in sand casting anyway
[22:21:57] <zeeshan> now i mean the actual sand mold

[22:27:25] <PetefromTn_> yeah I see your point
[22:27:50] <PetefromTn_> but with that thing or something like it you can quickly go from a small gang tool setup to a typical holder of course
[22:27:51] <XXCoder> PetefromTn_: its because people is too bored to make boring bars
[22:28:06] <andypugh> You need a height adjustment for each tool separately I think.
[22:28:12] <zeeshan> defiunitely do
[22:28:23] <PetefromTn_> I think it is built into the holder somehow
[22:28:32] <andypugh> So, the QCTP isn’t thee for height adjust

[22:52:25] <malcom2073> I guess they just wanna be normal like everyone else
[22:53:19] <XXCoder> theres this saying - deaf can do anything but hear
[22:53:26] <XXCoder> that guy certainly proves it.
[22:54:26] <ssi> XXCoder: have you heard about the guy that teaches people how to echolocate?
[22:54:53] <XXCoder> yeah that falls under "what deaf can't do" column lol
[22:55:02] <XXCoder> interesting though
[22:55:06] <ssi> well yea but
[22:55:30] <ssi> there was a story about it on radiolab, and they were talking about how blind people generally are told their whole lives that they can't do all sorts of things
[22:55:50] <ssi> but if they are just given the freedom to do what they want to do, they can actually learn to get around way better than people give them credit for
[22:56:04] <ssi> instead generally they get coddled and sheltered and they never learn to fend for themselves
[22:56:07] <XXCoder> malcom2073: thankfully he was threatening via vp call with friend, and that friend reported.
[22:56:08] <ssi> was interesting
[22:56:20] <malcom2073> huh
[22:56:36] <malcom2073> yeah, I've heard that before ssi
[22:57:16] <ssi> the thing that was hilarious to me at the time was the people reporting on it were the same people who believe that the best thing you can do for poor people is give them free stuff :)

[23:00:06] * Jymmm shoves weeds into ssi battery charger and VG in his bong!
[23:00:24] <XXCoder> SpeedEvil: so all deaf cant do jobs. good to know.
[23:00:57] <SpeedEvil> XXCoder: Deaf can't do all jobs.
[23:00:57] <ssi> not sure that's what he said
[23:01:02] <SpeedEvil> Subtly different.
[23:01:09] <XXCoder> SpeedEvil: hearing cant do all jobs.
[23:01:41] <SpeedEvil> Sure - but people with a sensory or other deficit, added to the normal range of human capabilities is likely to be able to do fewer jobs.
[23:01:58] <XXCoder> that includes dishwashing jobs?
[23:02:05] <XXCoder> because I couldnt even get thaty
[23:02:18] <XXCoder> and I have IT and CS jobs but couldnt even get that jobs
[23:02:39] <SpeedEvil> I note that at the moment, in order to be able to get employment, that employment would need to pay around $1000/hr, for 15 minutes at a time work, at irregular times, without counting transport.
[23:03:05] <SpeedEvil> I am not practically employable for health reasons - nomatter how compliant and reasonable the employer.
[23:03:44] <SpeedEvil> For dishwashing and similar jobs, it's almost certainly quite reasonable for someone who's deaf to do them, with minor adjustments.
[23:03:52] <XXCoder> my current job as cnc machinist? I had to go to training job for while, and I failed interview because specifically deaf few times
[23:04:00] <XXCoder> then I FINALLY got perment job
[23:04:25] <XXCoder> SpeedEvil: so why 80% unemployment?
[23:05:01] <SpeedEvil> XXCoder: I'm not saying tehre isn't bias - just that capability also exists. Sometimes it is cheap and reasonable to facilitate a disabled person working.
[23:05:12] <SpeedEvil> Other times. it is prohibitively expensive.

[23:10:07] <SpeedEvil> Hmm - I hadn't considered pre-birth audio.
[23:10:14] <XXCoder> and CT is... problemic and hotly contrested in deaf culture.

[23:12:59] <XXCoder> not always affect hearing

[23:14:16] <XXCoder> so many minor problems
[23:14:40] <SpeedEvil> I got great luck genetically. And caught a bug at age 12.
[23:16:03] <XXCoder> my dad wasnt genetically deaf either. he got serious illness and become deaf in 1940s something

[23:18:39] <XXCoder> some high ranking guy was behind him and he couldnt hear him
[23:18:44] <XXCoder> so he was caught out
[23:18:55] <XXCoder> he was honorably discharged
[23:19:41] <XXCoder> basically he was disciping him for doing wrong job. he didnt react so he shouted. nothing. so he patted on shoulder with hand.
[23:21:35] <XXCoder> SpeedEvil: what helps is he knew how to speak
[23:21:39] <XXCoder> being late deafened
[23:22:27] <SpeedEvil> Yeah - hence the earlier question about born deaf.
[23:22:32] <SpeedEvil> It's very, very different.
[23:22:39] <SpeedEvil> Same with blind people.
[23:22:47] <XXCoder> yeah assumed so
[23:22:50] <SpeedEvil> I found a fascinating study on braille.
[23:22:56] <XXCoder> my family is largely deaf
[23:23:11] <SpeedEvil> If you are under 6, when you learn to read braille, you can get up to several hundred wpm.
[23:23:23] <XXCoder> my bro has 4 children, one is deaf and 2 definitely carrier for waardingberg. one hearing
[23:23:30] <XXCoder> wow
[23:23:34] <SpeedEvil> If you start learning at 9 or older, you will top out at well under 50 in many cases.

[23:53:41] <JT-Shop> on X on the back side put a ramp thing on the fixed part on each end and a microswtitch on the axis
[23:53:56] <JT-Shop> similar on Y

[23:55:14] <XXCoder> interesting
[23:55:18] <JT-Shop> you don't want to crash into the switch just go past it and hit the hard stop
[23:55:21] <XXCoder> so it triggers when it unpresses
[23:55:33] <JT-Shop> no, trigger on press
[23:55:39] <XXCoder> your plama
