[03:49:11] * Tom_itx pokes tiwake with a sharp stick
[03:49:17] <Tom_itx> feel better now?
[03:53:33] <tiwake> enh
[03:53:46] <tiwake> sorta
[03:54:06] <tiwake> I'm getting ready to back a kickstarter for a space shooting game
[03:54:24] <tiwake> https://www.kickstarter.com/projects/309114309/infinity-battlescape
[04:02:45] <Praesmeodymium> I been burned by kickstarter games
[04:03:47] <Praesmeodymium> that looks good and all but I ssuspect the ship fates are waaaaay of they dont have a prealpha demo availible till january according to cuurent estimates
[04:04:34] <Wolf_> 0.o
[04:04:41] <Praesmeodymium> thats a huge red flag for me at this point, if a game isnt mostly finished I am not interested
[04:05:41] <Wolf_> Hardinge 50V collet
[04:05:48] <Wolf_> pain in the ass to find?
[04:05:59] <tiwake> Praesmeodymium: I've been following its development for ~4 years now. They (1-2 guys) started working on their game engine about 10 years ago because no game engine could do what they wanted to do.
[04:08:53] <tiwake> the game engine is fantastic with how they implement ray tracing, atmospheric scattering, fluid mechanics, orbital mechanics, newtonian physics... I really don't like the plastic look of most modern game engines
[04:10:58] <Wolf_> Looked at that $500 Van Norman Ram Type mill today, 22LU with a 50V spindle :/
[04:12:44] -!- bobo__ [bobo__!63283ad9@gateway/web/freenode/ip.99.40.58.217] has joined #linuxcnc
[04:13:37] <Wolf_> that damn 50V collet part kinda makes the deal look shitty
[04:16:33] <bobo__> Wolf " Hardinge 50V collet - pain in the ass to find " I think you forgot very expensive and limited as compared to Cat 40/50
[04:17:04] Valen1 is now known as Valen
[04:17:30] <Wolf_> http://i.imgur.com/tiB9E3O.jpg
[04:17:40] <Wolf_> I know where one is...
[04:19:24] <bobo__> Have seen several Van-Norman mills unsolded because of the collet problem
[04:21:28] -!- jerryitt has quit [Quit: Connection closed for inactivity]
[04:21:52] <Wolf_> wonder if that could be redone with a cat40
[04:22:54] <Wolf_> lol http://www.amazon.com/dp/B006FQ3KDM/ref=biss_dp_t_asn ! fuck
[04:23:40] <bobo__> To my thinking ,a mill of that size that doesent have a least a #40 taper is not worth the time and money
[04:24:33] <Jymmmm> Wolf_: FREE shipping =)
[04:25:01] <bobo__> least a #40 taper means no R8 ore Morse tapers
[04:25:06] <ssi> Wolf_: have you looked into the stmbl enough to know how to go about initial testing?
[04:25:10] <Wolf_> its crusty and rusty http://imgur.com/a/kNpN7
[04:25:19] <Wolf_> ssi: nope lol
[04:25:42] <ssi> I have one built
[04:27:26] <Wolf_> oddly that mill even had all the parts to go with it, including a 3phase 2hp motor
[04:28:09] <bobo__> ssi send it to zeeshan for fault testing
[04:32:25] <bobo__> Wolf a Van-Norman spindle taper could be changed , but just the material and maching cost ,to me would mean a newer mill would be better
[04:32:45] <Wolf_> what sorta cost?
[04:33:36] Jymmmm is now known as Jymmm
[04:35:10] <bobo__> mach the two spindles harden and grind and spindle material also mayby different bearings
[04:38:48] <bobo__> I wonder if Hardinge still makes the 50v collets, never mind their price
[04:39:44] <Wolf_> http://shophardinge.com/productGrid.aspx?catID=1629 maybe
[04:43:42] <bobo__> Oh gosh even at a 50% off sale they are above my price range
[04:46:58] <Wolf_> http://www.spsspindle.com/sps-spindle-services/spindle-rebuilding/spindles-we-service/ lol looks like every thing but a Van-Norman
[04:48:24] <t12> i wonder if my ghetto kinematics will work
[04:48:51] <t12> https://www.dropbox.com/sc/0aco3k384qqloxl/AABizEHHVSI9us-OT0df_HT4a
[04:49:07] <t12> to be replicated on front of headstock
[04:49:54] <t12> i guess if it repeats and is stable it will work
[04:52:49] -!- tchaddad has quit [Remote host closed the connection]
[04:53:13] <bobo__> Wolf I think that place is listing CNC machine type spindles, not the manual mill type spindles
[04:54:38] <Wolf_> set up a grinder on my 7x10 lathe tool post and bolt the lathe to the Mill table? :D
[04:55:33] <bobo__> you arn't british
[04:57:08] <bobo__> that would be something they would do. and some of them would pull it off too
[04:57:14] <Wolf_> or make a grinder up https://www.youtube.com/watch?v=jyzp--7VYvY
[05:01:29] <bobo__> compare the size of a 30 or 40 tool holder shank(end that goes in spindle) to even a R8 collet
[05:02:37] <bobo__> I think a R8 is close to size of #30
[05:06:29] <Wolf_> cat 30 is 1.25” x 1.875”L
[05:07:41] <Wolf_> 50V is ~1.57”
[05:08:20] <bobo__> might be worth asking ssi or zeeshan or tom if they could overlay them with a 50v in solid works for you
[05:08:42] <Wolf_> if its possible to find a 50V drawing
[05:10:04] <bobo__> hardinge might have (still) drawings
[05:10:49] <bobo__> know they did at one time
[05:11:35] -!- Miner_48er has quit [Read error: Connection timed out]
[05:13:13] <bobo__> they would tell you everything , except how they made them
[05:13:45] <Wolf_> yeah, not gonna buy one to figure it out
[05:14:33] <bobo__> there drawings were free or very cheap
[05:15:44] <bobo__> 50v drawing might be on their web site
[05:19:26] <bobo__> time was Hardinge were very easy to talk to, but I am past 70 and stuck in what once was thinking
[05:21:27] <Wolf_> hmm
[05:21:46] <Wolf_> other option would be to have a r8 adapter made
[05:23:23] <bobo__> other option could be to - look at a newer type mill
[05:25:00] -!- skunksleep has quit [Ping timeout: 255 seconds]
[05:26:39] -!- Miner_48er has quit [Quit: Leaving]
[05:28:50] <bobo__> those older mills are just the thing for pealing the hard skin off cast iron castings day in day out, last I looked foundrys have become few
[05:29:37] -!- dnalerom_ has quit [Ping timeout: 244 seconds]
[05:30:10] <bobo__> foundries
[05:30:44] <Wolf_> well, it is a neat machine from what I have read, except the whole odd spindle bore problem
[05:31:24] <bobo__> it was not odd then, just now

[05:33:40] <Wolf_> not much else on craigslist for this area, http://york.craigslist.org/tld/5258435244.html is the next cheapest
[05:35:13] <ssi> hardinge is still proud of their parts
[05:35:44] -!- skunksleep [skunksleep!~AndChat14@str-broadband-ccmts-ws-26.dsl.airstreamcomm.net] has joined #linuxcnc
[05:35:50] <Wolf_> big jump from $500 too...
[05:36:05] <bobo__> Wolf have you looked at what HGR is selling ?
[05:36:28] <Wolf_> whats HGR
[05:37:39] <bobo__> Cleveland Oh. used mach + kitchen sink dealer
[05:38:08] <Wolf_> not too close for me
[05:38:31] <bobo__> you and Pete
[05:39:18] <bobo__> HGR has a web site
[05:40:15] <Wolf_> 340mi...
[05:41:18] <bobo__> bet if you took a flashlite and poked around there might even be some 50v collets
[05:41:18] <Wolf_> like $204 just in fuel to get there and back
[05:41:38] <ssi> lol
[05:41:41] * ssi does some math
[05:41:50] <Wolf_> give or take $50
[05:42:08] <ssi> it would cost me $32 round trip to go that distance in my car
[05:42:39] <ssi> it would cost me $121 round trip to go that distance in my airplane, at 180mph
[05:42:40] <Wolf_> thats w/ the truck, w/ just under 3-4 tons available for load
[05:43:10] <ssi> if I took the car and the trailer I could haul a ton back, and I'd probably burn $50 in fuel instead of $32
[05:43:56] <ssi> I could haul four tons for about the same price in fuel as your truck
[05:43:59] <ssi> it'd just take me four trips :)
[05:44:00] <Wolf_> $51 for the car, figuring $3 gal fuel
[05:44:08] <bobo__> $204 wont even buy a Hardinge collet , you are too young to be thinking like me . get with it whipper snapper
[05:46:17] <Wolf_> wait, wtf are you driving ssi?
[05:46:44] <Wolf_> 680mi round trip for me to cleveland
[05:47:12] <ssi> a car so good on gas the government had to ban it
[05:47:41] <ssi> I never believed any of those conspiracy theories before
[05:47:50] <Wolf_> what is it?
[05:47:57] <ssi> the ones like "did you hear about the guy who invented a carburetor that could get 100mpg? he disappeared"
[05:48:11] <bobo__> Wolf who cares what ssi is driving. offer to pay $40 for gas
[05:48:19] <ssi> vw diesel
[05:48:24] <Wolf_> my pos only gets like ~40 mpg
[05:48:27] <ssi> I figured that at 50mpg
[05:48:36] <ssi> but on long highway trips I can actually do 57+
[05:48:59] <Wolf_> but mine isn’t broken in, and has the DPF/DEF system as well
[05:49:03] <Wolf_> and its DSG
[05:49:13] <ssi> I have dpf
[05:49:18] <ssi> no def on the jetta
[05:49:26] <ssi> dsg is a penalty for sure
[05:49:36] <ssi> mine's definitely broken in though
[05:49:37] <Wolf_> I have a ’15 golf wagon
[05:49:41] <ssi> it's a 2014 and I have 63k on it
[05:49:45] <Wolf_> not even 4k on it yet lol
[05:49:56] <bobo__> swing by here and I will pop for lunch or dinner
[05:50:04] <ssi> but it's 100% stock except for the radio :)
[05:50:16] <ssi> 57+mpg requires driving 62mph and no AC
[05:50:33] <ssi> and it doesn't take much traffic to wreck those numbers
[05:50:58] <ssi> you better hang onto that car though, cause you'll never get another one
[05:51:03] <Wolf_> yeah, I leave mine on auto climate… and don’t drive 62 lol
[05:51:31] <Wolf_> I’m waiting for the recall, then going to get a malone tune :D
[05:51:46] <ssi> yeah I intend to do the same thinhg
[05:51:58] <ssi> but I noticed malone took the details about their dpf delete tune off the website
[05:52:01] <ssi> that concerns me a bit
[05:52:16] <Wolf_> one of the MD guys has the DPF delete tune
[05:52:20] <Wolf_> on a 15
[05:52:56] <Wolf_> I don’t think malone listed the dpf/def delete tune on the site for the ’15, but it does exist
[05:53:13] <ssi> I hope so
[05:53:37] <ssi> I've heard gains of 7-10mpg from the dpf delete tune
[05:53:45] <ssi> I need that in my life
[05:54:05] <Wolf_> I was thinking about hitting the guy up that has the delete done and seeing if I can borrow his stock parts for a weekend and build a welding jig up :D
[05:54:24] <ssi> that's a good idea
[05:55:17] <ssi> I'll have my 2 post lift soon enough, maybe it won't be so hateful to remove that I can't pull it and pattern it

[05:57:57] <ssi> oh emm gee they're dropping the subframe and the axles :(
[05:58:02] <Wolf_> well that looks like a total bitch
[05:59:17] <ssi> one other thing I'd really like to do to that car is put some better brakes on it
[05:59:27] <ssi> I traded a '12 Golf R in for the TDI
[05:59:34] <Wolf_> hah yeah
[05:59:34] <ssi> and I thought I was gonna die for the first month
[05:59:38] <ssi> the brakes feel SOOOOO spongy
[06:00:11] <Wolf_> the wagen isn’t very impressive on the brake end of thing either
[06:00:26] <Wolf_> look really damn small in 18” wheels too
[06:00:39] <Wolf_> http://s685.photobucket.com/user/Richkid064/media/image13_1.jpeg.html
[06:01:00] <ssi> lol dang
[06:01:21] <Wolf_> I have no idea wtf all that crap is there lol
[06:02:00] <Wolf_> looks like that down pipe might work tho
[06:02:37] <ssi> you know what?
[06:02:49] <ssi> I think if I do this, I'll pay someone to make and install :)
[06:03:20] <Wolf_> Thinking the same thing here
[06:04:37] <ssi> yeah... that looks like about the worst possible job
[06:05:16] <ssi> I have all the arms and the top plate of my lift painted
[06:05:25] <ssi> need to wire brush and paint the colums and actuators
[06:06:15] <Wolf_> ok that doesn’t look that bad http://s685.photobucket.com/user/Richkid064/media/image14_1.jpeg.html

[06:21:18] <bobo__> could call them and ask what that item number sold for

[14:50:41] <cradek> sometimes there are bios settings for "stay on" etc
[14:50:53] <lair82> I think it hassomething to do with this page, http://postimg.org/image/5jhvcyoxv/
[14:51:27] <lair82> Oh, I will have to look at the bios
[14:51:59] <cradek> well, backing up, does it just log out and back in, or reboot, or something else?
[14:54:48] <lair82> No, I click "Shutdown" on the popup at the bottom of the screen. it logs out, then you see all the shutdown scripts, then the last ting I see is "power down" then the screen goes blank, then I get the "No Video' on the display, and then it boots back up after about a second or two.
[14:55:14] <cradek> oh yeah, then that's bios or hardware, not linux
[14:55:28] <lair82> Ok,
[14:56:00] <Roguish> definitely BIOS.

[17:08:02] <tiwork> 10,000RPM+
[17:08:06] <mutilator> so probly just too slow

[17:09:11] <tiwork> squirting some WD40, or some other thin lubercation on the surface will help

[17:17:20] <tiwork> I'm trying to decide if I need a salt to seal with or not
[17:17:23] <maxcnc> homebuild lasers are more cool
[17:17:26] <tiwork> and just use boiling water
[17:17:31] <archivist> tiwake, I worked at a place that did it but on other jobs not anodizing
[17:18:08] <tiwork> like if I put it in a nickle acetate bath or just hot water bath
[17:18:11] <Erant> maxcnc: I converted a LittleMachineShop micro mill to CNC (well, modulo the control card, obviously) and that's a nice little machine with a work surface that area.
[17:18:12] <maxcnc> mutilator: where are you in this "Blue" earth
[17:18:30] <archivist> tiwake, iirc it was just hot (boiling) they also rubbed lanolin into the surface after

[17:23:49] <maxcnc> mutilator: so you dont have access to building mashines
[17:23:55] <mutilator> yea i do
[17:24:06] <mutilator> we dont have anything crazy here, just an engraver
[17:24:18] <mutilator> basically like the $1600 machine except costs more cause it wasnt made in china
[17:24:28] <maxcnc> so get a good used tube for 100 Dollar and build your mashine around
[17:24:58] <maxcnc> 80W co is alover

[17:25:36] <tiwork> erm
[17:25:44] <tiwork> wrong person
[17:25:48] <tiwork> archivist ^
[17:25:49] <andypugh> I thought as much
[17:26:00] <mutilator> yea max, i've thought about it
[17:26:06] <andypugh> Easy mistake to make, but I am the tall handsome one.
[17:26:26] <tiwork> andypugh: you can throw in your opinion too! I'll take all of them that I can get XD
[17:26:35] <archivist> I claim to be fugly
[17:26:45] <tiwork> lol
[17:26:54] <maxcnc> mutilator: i only asked at the Universety Mechanics and they got 4x 200W in a box
[17:27:07] <andypugh> I only claim to be tall and handsome on the internet. I don’t get away with it in person.
[17:27:23] <tiwork> andypugh: context is I am setting up anodizing for my first time, one of the things I need is a good aluminum cleaner.
[17:27:29] <maxcnc> mutilator: they work most on the far end noone of us woudt go
[17:27:50] <maxcnc> so they got stuff that is out of order
[17:28:03] <andypugh> I am afraid I always take the easy way out and pay the local anodiser £10. (it is always £10, regardless of quantity or size of parts)
[17:28:04] <archivist> tiwake, the process hase cleaning/stripping of the old oxide anyway
[17:30:01] <tiwork> there is this, http://www.caswellplating.com/anodizing-products/anodizing-accessories/aluminum-deoxidizer-desmut-1-quart.html
[17:30:10] <tiwork> but I'm not sure if I should look for something else
[17:31:05] <mutilator> oh..
[17:31:12] <mutilator> so the other things.. the wd-40 recommendation
[17:31:29] <tiwork> wd40 works well because its really thin
[17:31:43] <mutilator> the way i secure the charm to the surface to mill is put a piece of clear packing tape over the metal
[17:31:50] <mutilator> maybe thats why it's not clearing the stuff
[17:32:01] <mutilator> i dont know why it didnt occur to me until now
[17:32:19] <tiwork> wait, over the entire surface?
[17:32:23] <mutilator> heh yea
[17:32:25] <tiwork> (lol)
[17:32:43] <tiwork> yeah, wanna talk about gummy... plastic with glue on it?
[17:32:59] <archivist> andypugh, did you fix your dropped probe?
[17:32:59] <mutilator> yea, i didnt figure it'd affect the metal
[17:33:04] <mutilator> but it probably is
[17:33:13] <tiwork> it certainly is
[17:33:15] <tiwork> lol
[17:33:30] <mutilator> i need to make some sort of mask to clamp it down
[17:33:49] <archivist> you will be causing re cutting of the chips if they cannot be cleared
[17:34:18] <andypugh> archivist: The broken rods were still _just_ long enough to work, so I put it back together with the remains.
[17:34:20] <mutilator> was the simplest solution to secure it down
[17:34:26] <mutilator> need to figure out another way
[17:35:01] <archivist> andypugh, I wondered if you would just make new rods :)
[17:35:47] <andypugh> Plan B was broken 3mm carbide milling cutters.
[17:36:00] <andypugh> Of which I have quite a stock

[18:00:10] <Nick001-shop> Using a 10,000 ufd 100vdc capacitor across a 48vdc power supply for a servo, what size resister and how many watts should I be using to discharge it?
[18:00:38] <Erant> That depends on how long you want it to take.
[18:02:04] <andypugh> I know that with 300V and about the same capacitance it turns out to be a crazy amont of power, so I set up a crowbar relay instead.
[18:03:40] <Erant> It is, you can slowly discharge it through ~100 Ohms which initially would give you an amp of current or about 100W
[18:04:14] <Nick001-shop> Trying to keep it simple - just across the cap to discharge it quickly when I turn it off.
[18:05:03] <Erant> If you don't mind it taking a minute or so to discharge, 1k ohm would work.
[18:05:07] <archivist> define quickly
[18:05:37] <maxcnc> andypugh: thanks
[18:06:12] <andypugh> If RC = 1 second then R = 100 (as mentioned) and power is 25W
[18:06:40] <andypugh> So, a 25W 100R would work. But would be warm and wasteful.
[18:07:00] <Nick001-shop> Will that work for a 10-15 amp supply?
[18:07:04] <andypugh> (In my scenario the same calculation was 900W !
[18:07:07] <Erant> andypugh: There's a higher peak power though. Initially, when the thing is charged at 100VDC and there's a 100R load there'll be a 1A current.

[18:07:51] <Erant> Yeah, what andy said then.
[18:07:52] <andypugh> (100V cap, which is an elephant)
[18:08:22] <archivist> dont use too low a resistor unless you have a relay
[18:08:35] <Erant> But you won't need a 25W 100R resistor. You can probably get away with something smaller as the ratings on resistors are specced for continuous load.
[18:08:43] <Erant> This'd be peak load.
[18:08:44] <andypugh> Yeah, 100V is 100W, 300V is 900W. As the voltage goes up it gets crazy quickly
[18:09:01] <archivist> no relay is continuous :)
[18:09:24] <andypugh> Erant: If it is permanently conected it needs to be 25W

[18:09:57] <Erant> I thought this was just for discharging? You'd only connect it when you're discharging. Otherwise you've got yourself a nice space heater.
[18:09:58] <archivist> or wait longer for discharge and use a higher value
[18:10:26] <Erant> Put on a NC relay and you're done.
[18:10:40] <andypugh> My impression was that it would be permanently connected. It was my 300V supply where the relay was inportant

[18:10:59] <archivist> most thing use a higher value and a label on the outside to wait a minute
[18:11:02] <Erant> Fair enough. Seems a little wasteful.
[18:12:11] <andypugh> Incidentally, if your relay welds shut and you put mains voltage across a 25W 100R for long enough, then the resistor explodes with enough force to punch the ends through aluminium: https://picasaweb.google.com/108164504656404380542/PSU#
[18:12:16] <malcom2073_> My servo cage power supply has a 20W resistor permanently connected, it does get quite toasty
[18:13:17] <archivist> I had a few explode on one of my vfd's

[18:27:36] <Erant> On a totally unrelated topic, I'm planning on replacing the steel trapezoidal nuts on my mill with some delrin anti backlash ones. My screws are TR12x2 and no commercial ones exist, so I ordered a tap and am making my own. How much pressure should the two parts of the nuts exert on each other?
[18:28:08] <Erant> Trying to figure out which springs to get.
[18:29:31] <cradek> ideally just a little more than your maximum cutting force
[18:29:56] <cradek> make an adjustable system if at all possible
[18:30:03] <Erant> That's sort of what I figured.

[18:30:14] amnesic is now known as amnesic_away
[18:30:16] <cradek> compress the spring more by giving one half of it a twist, and then pin it in place somehow
[18:31:40] <cradek> or is the springiness radial? that's how mine are

[18:45:02] <Praesmeodymium> I see delrin and pom nuts and wasnt convinced plastics would survive milling forces... but i guess I was worried for naught
[18:45:47] <andypugh> To be honest, ballscrews are now so cheap I don’t see a reason not to switch, except that ball nuts won’t always fit
[18:46:29] <Erant> andypugh: Yeah, I've seen those... I'd rather engineer it properly for wear adjustment.
[18:46:32] <CaptHindsight> somebody asked for a quote for a SLA printer the size of that lathe for printing urethane cylinders
[18:46:48] <andypugh> Sounds like fun
[18:47:04] <Erant> Right, I was thinking about ball nuts but I'd have to add gearing to my servos.
[18:47:07] <CaptHindsight> 1.5m dia and 7m between centers
[18:47:15] <andypugh> I reckon that is neither a shaft or an axle. I think it is a roll
[18:47:55] <Erant> My current screws are like 20TPI. Ball nuts are like 5, and my servos don't have enough torque for that.
[18:48:03] <CaptHindsight> I'd like to see what that roll is when its finished

[18:51:01] <CaptHindsight> it would be funny if they used a 1m dia dial indicator to center that part :)
[18:52:33] <andypugh> Centering it probably took days. It isn’t round, so there is a fair bot of surveying needed to make sure you don’t miss a bit.
[18:53:03] <Erant> andypugh: Huh. That's actually interesting.
[18:53:31] <Erant> I just need the end of the shaft ground down to 8mm and that'd be that.
[18:54:05] <andypugh> If you have a lathe then machining ballscrew isn’t that difficult. A CBN insert helps.
[18:54:47] <andypugh> Your problem would be fitting the nut in. Make sure you can do that before comitting. Ball nuts are pretty big
[18:59:32] <Erant> I have a reasonable amount of space, let me measure.
[18:59:51] <andypugh> Right, time to paint patterns.
[19:08:47] <Erant> The Y slide would work just fine (1 1/4" of clearance) the X slide would need to be modified a little to sink the nut.

[20:29:39] <Akex_> How the 7I76 have a 48 i/o with one db25 ? I dont understan that
[20:30:05] <ssi> multiplexing
[20:30:30] <Akex_> Ok ssi
[20:30:55] <ssi> more specifically, something called smartserial
[20:30:57] <Akex_> If i have a 5i25 how say a this card, do a multiplexing ?
[20:31:00] <PetefromTn_> its all about the magical MESANET Trons!!
[20:31:31] <ssi> there's 17 pins on the db25 that carry io, most of them are your step/dir lines, but a couple are a high speed serial link
[20:31:50] <Akex_> With a special firmware ?
[20:31:56] <ssi> the serial data carries over to the field IO processor, which sets/reads the state of the IO pins and communicates back to the fpga on the 5i25 via 2.5mbit serial
[20:32:32] <malcom2073_> Akex_: Yes X over ssh is very slow
[20:32:45] <Akex_> I undersatand how comunicate
[20:32:46] <malcom2073_> You can disable the Axis backplot to help it a bit
[20:32:57] <malcom2073_> I use tkemc, since it responds much quicker over ssh
[20:33:09] <Akex_> malcom2073_: just x over ssh or the BBB is very slow ?
[20:33:13] <malcom2073_> Akex_: Both
[20:33:28] <Akex_> Very sad malcom2073_
[20:33:35] <andypugh> Akex_: The spec for smart-serial is in the back of the 5i25 manual.
[20:33:56] <malcom2073_> Yep, that's kinda why I only use machinekit for my printer. It would annoy me to no end to try and use for my mill, due to the lack of responsiveness
[20:34:03] <Akex_> Ok andy i will read that
[20:34:37] <malcom2073_> Akex_: Try some of the remote control applications they have now
[20:34:39] <malcom2073_> machineface or whatnot?
[20:34:39] <Akex_> Ok malcom2073_ ...
[20:34:47] <malcom2073_> Rather than running X over ssh, run it completly headless
[20:35:23] <Akex_> For the moment i try how it work malcom2073_
[20:35:45] <Akex_> And how config

[20:43:55] <Wolf_> lol
[20:44:04] <MacGalempsy> I saw that photo yesterday and was wondering what it was all about
[20:44:16] <MacGalempsy> is that an aluminum spacer?
[20:44:20] <malcom2073_> It is heh
[20:44:27] <MacGalempsy> :/
[20:44:36] <malcom2073_> Eh, it's strong enough in compression
[20:44:54] <malcom2073_> It's only a spacer anyway, no power is transmitted through it, that's what the set screw goes through it for

[21:20:43] <Praesmeodymium> chem labs
[21:20:56] <Praesmeodymium> oil based most likely
[21:21:28] <XXCoder> heh reminds me of that old dinsour sitcom
[21:21:36] <XXCoder> they was discussing medicine
[21:21:36] <Praesmeodymium> analine dyes were revolutionary
[21:21:40] <tiwork> www.caswellplating.com/violet-ds-anodizing-dye-4-oz.html isnt oil based...
[21:21:45] <XXCoder> doctor takes out bottle of orange liquid
[21:22:08] <XXCoder> said massive team of scientists found it by research
[21:22:22] <XXCoder> guy asks whats it, and doc says "it's orange!"
[21:22:25] <XXCoder> :P
[21:22:37] <tiwork> heh
[21:22:51] <Praesmeodymium> I think you misunderstood my intended meaning, being derived from oil as in oil based is not the same as based in oil solution
[21:23:08] <XXCoder> that dad brings it to wife, she asks whats it, and he says "it's orange!"
[21:23:27] <XXCoder> Praesmeodymium: nah just slightly unrelated. man havent thought about that old sitcom for years.
[21:23:54] <XXCoder> https://en.wikipedia.org/wiki/Dinosaurs_%28TV_series%29
[21:24:08] <Praesmeodymium> heh I should preface my sentences, I remember seein gthe pilot of that dino show and thinking I want my 30 minutes back
[21:24:33] <tiwork> XXCoder: makes me think of an orange stereolithography resin
[21:24:35] <XXCoder> Praesmeodymium: well 90s and deaf you take what captioned tv shows you can
[21:24:37] <tiwork> for some reason
[21:24:52] <XXCoder> otherwise its adlib games :P

[23:18:15] <PCW> 500 usec is OK on a 1 KHz thread:
[23:18:16] <PCW> If the stepgen position and encoder readings are sampled on time (via the DPLL) , latencies just cause delays
[23:18:18] <PCW> in the write which only causes minor second order errors in velocity mode servos (which includes the stepgen)
[23:20:47] <XXCoder> probably not safe for work (dunno as not captioned) https://www.youtube.com/watch?v=lzBHA7QxJEs
