[01:09:48] <eric_unterhausen> is that a double screw?
[01:10:00] <eric_unterhausen> or what is the coarse thread in the back?
[01:10:02] <uw> looks like spring
[01:10:11] <eric_unterhausen> duh
[01:10:15] <uw> for back lash lol
[01:10:21] <eric_unterhausen> ic now
[01:10:53] <eric_unterhausen> isn't newport pretty much it for motorized mini-slides?
[01:11:13] <uw> i wish there was pencil or something next to it for scale
[01:11:30] <eric_unterhausen> 1/4-20 hole in slide
[01:11:44] <uw> oh gotcha
[01:11:48] <uw> that is mini

[01:16:06] <Valen> you can get micro steppers with linear actuators off the ebays for a $ or two
[01:17:08] <CaptHindsight> each positioner is ~0.5" x 1.75"
[01:18:53] <CaptHindsight> http://www.ebay.com/itm/370989283234 bingo, thanks Valen
[01:19:26] <uw> wonder if they make steppers the size of cellphone vibra motors
[01:19:52] <CaptHindsight> I tried linear stage, xy stage, etc etc on ebay
[01:20:02] <CaptHindsight> sometimes it takes the magic words
[01:20:29] <Valen> uw i have some 6mm dia steppers

[02:11:05] <julby0> *105
[02:11:15] <CaptHindsight> maybe 90 left?
[02:11:33] <Tom_itx> some of the ole pharts are sleepin in their chairs
[02:11:47] <eric_unterhausen> some people are always leaving
[02:11:56] <eric_unterhausen> is there a way to turn off those messages?
[02:12:04] <Tom_itx> what messages?
[02:12:07] <Tom_itx> join part?
[02:12:13] <Tom_itx> depends on your client
[02:12:16] <eric_unterhausen> left/join
[02:12:31] <Tom_itx> i remove them from my logs
[02:12:33] <eric_unterhausen> I was looking for that, didn't see it
[02:12:38] <julby0> I have 10-12 years of computer programming experience (lots of languages), I'm 24, and I'm thinking about going to vocational school to learn CNC and I'm wondering if that sounds like a bad idea to people? will i just be starting from scratch or is there overlap
[02:12:41] <Tom_itx> what client?
[02:12:50] <eric_unterhausen> pigin

[02:12:56] <Tom_itx> never used it, sry
[02:13:00] <eric_unterhausen> aka pidgin
[02:13:30] <Tom_itx> julby0 learn a cad cam package at a vo tech
[02:13:39] <CaptHindsight> julby0: by cnc you mean programming g-code or running cnc machines?
[02:13:47] <julby0> the school covers both
[02:13:54] <Tom_itx> if that's what you like
[02:14:15] <Tom_itx> programmers get paid more than button pushing monkeys
[02:14:21] <eric_unterhausen> I visited a votech that was selling a HAAS. That place looked really interesting
[02:14:38] <eric_unterhausen> there was a mastercam class going on, lots of students out on the floor machining
[02:14:50] <Tom_itx> yep they teach it here
[02:14:56] <Tom_itx> also catia
[02:14:59] <CaptHindsight> button pushing monkey programmer
[02:15:19] <zeeshan> Tom_itx:
[02:15:35] <zeeshan> at this one company i was working at, the button pushers got 22$/hr
[02:15:36] <zeeshan> lol
[02:15:44] <zeeshan> they did do measurements every 10th parth though
[02:15:57] <zeeshan> and were loading/unloading parts 3 machines at a time
[02:16:01] <Tom_itx> i was getting 35 for programming
[02:16:05] <CaptHindsight> some of us were just thrown into a machine shop and had to learn machine or sink
[02:16:08] <Tom_itx> way back when...
[02:16:08] <zeeshan> yea programmers get awayy more
[02:16:15] <eric_unterhausen> you can get engineering jobs that require cnc programming
[02:16:27] <zeeshan> eric_unterhausen: those jobs suck
[02:16:28] <zeeshan> :)
[02:16:37] <Tom_itx> CaptHindsight yep that's how alot of it is done
[02:16:38] -!- Demiurge has quit [Quit: Demiurge]
[02:16:43] <Tom_itx> sink or swim
[02:16:45] <eric_unterhausen> I met a guy that did it and seemed pretty happy about it
[02:17:01] <Tom_itx> i had a friend i got hired on at my bud's shop
[02:17:19] <Tom_itx> started sweeping the floors and left running quite a few of the machines
[02:17:22] <zeeshan> i'd kill myself
[02:17:28] <zeeshan> if my job was cnc programming
[02:17:31] <zeeshan> as a mech eng
[02:17:31] <julby0> why
[02:17:41] <zeeshan> cause i did that shit as a technologist for 2 years
[02:17:45] <zeeshan> and it got boring really fast
[02:17:46] <CaptHindsight> it also depends on what industry your machine shop is in
[02:17:53] <Tom_itx> yeah
[02:17:59] <zeeshan> i was programming robots (pick and place) and cnc machines
[02:18:04] <zeeshan> aerospace
[02:18:08] <Tom_itx> where?
[02:18:25] <CaptHindsight> are you on government/military contracts or some fading industry
[02:18:35] <Tom_itx> aerospace is becoming more locked in on price
[02:19:09] <zeeshan> you prolly havent heard of it
[02:19:11] <zeeshan> goodrich
[02:19:28] <Tom_itx> they make tires
[02:19:33] <zeeshan> wrong company
[02:19:34] <zeeshan> sir
[02:19:34] -!- patrickarlt has quit [Remote host closed the connection]
[02:19:37] <Tom_itx> :)
[02:19:38] <zeeshan> haha
[02:20:00] <Tom_itx> i didn't say they had a blimp
[02:20:13] <zeeshan> yea i went back to school and doing my masters
[02:20:17] <zeeshan> so i can do a mix of things
[02:20:26] <zeeshan> for me personally icant handle doing the same thing
[02:20:30] <zeeshan> need something new
[02:20:49] <Tom_itx> you'd get bored quick running cnc
[02:20:55] <CaptHindsight> zeeshan: what were the pick-n-place files like? just X xxxx.xxx , Y xxxx.xxx or similar?
[02:20:56] <zeeshan> i know plenty of people that love programming through mastercam
[02:21:10] <Tom_itx> i looked at mastercam when i bought mine
[02:21:16] <julby0> is cnc anything like regular programming
[02:21:17] <Tom_itx> i didn't like it quite as much
[02:21:51] <zeeshan> CaptHindsight: theyre all the same
[02:21:54] <CaptHindsight> julby0: http://linuxcnc.org/docs/html/gcode.html
[02:21:57] <Tom_itx> the problem with small shops is most of the time the parts they get are stuff that is HOT and has to get done quick
[02:22:04] <zeeshan> you basically set joint mode , cartesian mode, set the speed
[02:22:05] <zeeshan> mvoe the arm
[02:22:12] <Tom_itx> unless you're a lucky one that has a contract for parts
[02:22:22] <zeeshan> mitsubishi has a different set of codes, fanuc has a different set of codes and abb has a different set of codes
[02:22:38] <zeeshan> by codes i mean commands
[02:22:51] <zeeshan> i wonder if i have the video of my making the robot dance
[02:23:01] <zeeshan> during plant shutdown
[02:23:01] <zeeshan> :)
[02:23:21] <zeeshan> towards the end it swoops down and turn its end effector and gave a middle finger pretty much
[02:23:29] <zeeshan> :)
[02:23:35] <CaptHindsight> zeeshan: was this you? http://www.youtube.com/watch?v=wOCmoYU6h1Q
[02:23:48] <zeeshan> CaptHindsight: no :(
[02:23:50] <zeeshan> i'd prolly puke
[02:23:57] <zeeshan> you wanna know what the abb robot was doing?|
[02:24:01] <zeeshan> its entire job?
[02:24:20] <zeeshan> it would take a part that came out of a cnc machine drilled in a bunch of places
[02:24:32] <zeeshan> and push it against a spinning bristle brush to deburr
[02:24:38] <zeeshan> and then load it to the other machine
[02:24:41] <zeeshan> poor robot.
[02:24:44] <CaptHindsight> for how long?
[02:24:52] <zeeshan> 30 second brush time
[02:25:08] <zeeshan> cycle time for the whole operation was like 45 seconds
[02:25:24] <CaptHindsight> did the robot ever complain, get sick or ask for a raise?
[02:25:33] <zeeshan> yes
[02:25:44] <zeeshan> it'd start dropping parts at the wrong place
[02:25:45] <CaptHindsight> serves managment right!!
[02:25:46] <zeeshan> haha
[02:27:07] <zeeshan> i cant find the damn video
[02:27:08] <zeeshan> but i did find this
[02:27:27] <zeeshan> http://i130.photobucket.com/albums/p252/turbozee84/3FC67967-6C17-494D-A3A7-FD9E7292EE55-2301-0000022C0117D1D9_zpsb6c30cb5.jpg

[02:29:23] <zeeshan> 2" diameter cables
[02:29:23] <zeeshan> ;D
[02:29:36] <CaptHindsight> big buss bar to
[02:30:06] <zeeshan> these guys used copper
[02:30:08] <zeeshan> like it was free
[02:30:31] <CaptHindsight> bending those conductors in a box is really fun
[02:30:45] <zeeshan> luckily those are aluminum
[02:30:49] <zeeshan> copper is retarded
[02:31:00] <zeeshan> they use a hydraulic bender
[02:31:41] <CaptHindsight> we also used a tool that was similar to a "hickey" bender
[02:32:29] <zeeshan> i found a set of pics from another job
[02:32:39] <CaptHindsight> that was in another life
[02:32:43] <zeeshan> http://i130.photobucket.com/albums/p252/turbozee84/work_abba_systems/PIC-0113.jpg
[02:32:58] <zeeshan> this job required "Reverse engineering", designing
[02:32:59] <zeeshan> and programming
[02:33:02] <zeeshan> i think the coolest part was
[02:33:04] <zeeshan> http://i130.photobucket.com/albums/p252/turbozee84/work_abba_systems/mold.png
[02:33:16] <zeeshan> the fact that those molds were all made out of stainless steel
[02:33:26] <zeeshan> and some of the components that went inside it needed to be "hard turned"
[02:33:39] <zeeshan> 62HRc hardness
[02:33:55] <zeeshan> the finishing was done on grinders that were stupid precise
[02:34:15] <zeeshan> they monitored the part diameter real time using a marposs made gauge
[02:34:21] <CaptHindsight> http://s130.photobucket.com/user/turbozee84/media/work_abba_systems/PIC-0116.jpg.html Faro arm?
[02:34:25] <zeeshan> and at the same time monitored the tool post vibration due to the machine
[02:34:43] <zeeshan> all while thats going on it'd closed loop it's way to its target dimension
[02:34:45] <zeeshan> amazing!
[02:34:49] <zeeshan> yes
[02:34:52] <zeeshan> faro arm
[02:35:16] <zeeshan> a lot of aerospace companies don't allow pics
[02:35:20] <zeeshan> :(
[02:35:58] <CaptHindsight> I just wear camera glasses now :)
[02:35:59] <Tom_itx> one here we visited was making 117 parts, they escorted us thru the shop

[02:37:08] <CaptHindsight> safety first
[02:37:08] <zeeshan> well that process i described to you earlier
[02:37:13] <zeeshan> its all propietry shit
[02:37:22] <zeeshan> they think others dont do it
[02:37:25] <zeeshan> but others are
[02:37:34] <zeeshan> so i don't know why all the secrecy
[02:37:41] <zeeshan> not anyone can start a 100million dollar operation overnight

[02:38:21] <julby0> in U.S.
[02:38:30] <CaptHindsight> FDM with carbon fiber in the filament
[02:39:00] <zeeshan> julby0: depends
[02:39:06] <zeeshan> if they're doing complex 5 axis programming
[02:39:07] <CaptHindsight> someone ^^ said used to make $35/hr
[02:39:13] <zeeshan> i've seen them make 35-40$ hr ez
[02:39:44] <julby0> that seems like the same as what a software engineer would make
[02:40:12] <CaptHindsight> depends on the area and projects
[02:40:12] <zeeshan> julby0: programmers make more initially

[02:41:30] <CaptHindsight> you don't get much hands on in engineering school, lots of reckinin, arts and lecture :)
[02:41:50] <zeeshan> i agree
[02:42:00] <zeeshan> thats why i started off at a technical college first
[02:42:17] <zeeshan> did 3 years there, got amazing experience and did co-ops and worked after
[02:42:21] <CaptHindsight> it all depends, some people get a BS is ME and end up making tons, some get PhD's and wash dishes
[02:42:33] <zeeshan> now im almsot done my undergrad and starting masters this summer
[02:42:43] <zeeshan> and you'll be suprised how many "engineers" can't hold a vernier caliper right
[02:42:51] <zeeshan> a venier caliper is not a 2 hand instrument!
[02:43:01] <zeeshan> nor is it a screw driver..
[02:43:15] <julby0> there's a wrong way to hold a caliper?
[02:43:28] <CaptHindsight> my way and the other way
[02:43:29] <zeeshan> julby0: theres a way to hold it that will get you laughed at by any machinst
[02:43:40] <julby0> why
[02:43:46] <zeeshan> you hold the caliper with one hand
[02:43:50] -!- lyzidiamond has quit [Quit: lyzidiamond]
[02:43:55] <zeeshan> use the thumbwheel to close the jaws
[02:44:02] <zeeshan> not close the jaws with both hands
[02:44:06] <zeeshan> it throws off your readings
[02:44:11] <julby0> i didn't know that
[02:44:26] <julby0> i wondered what the point of the thumbscrew was
[02:44:48] <zeeshan> http://www.listoftools.com/images/using_vernier_calipers_for_an_outside_diameter.png
[02:44:52] <zeeshan> hold part with one hand
[02:44:55] <zeeshan> hold vanier with other
[02:44:58] <zeeshan> vernier
[02:46:00] <eric_unterhausen> machinist will laugh at you anyway BTDT
[02:46:16] <julby0> the moral is that machinists have an odd sense of humor
[02:46:38] <zeeshan> i have a question for you guys
[02:46:45] <zeeshan> i love this question.
[02:46:57] <eric_unterhausen> it's when a man and a woman love each other very much
[02:47:08] <zeeshan> you have a manual lathe. you need to make 3x3x3 cube
[02:47:11] <zeeshan> how do you do it?
[02:47:11] <zeeshan> :D
[02:47:16] <Tom_itx> easy
[02:47:19] <zeeshan> haha
[02:47:24] <zeeshan> Tom_itx: don't ruin it!
[02:47:39] <eric_unterhausen> ya, I can do that, and I actually have
[02:47:46] <zeeshan> that was one of my final exam questions in college lol
[02:47:48] <Tom_itx> you can make one of those cube in a cube in a cube like that too
[02:48:07] <zeeshan> tell me!
[02:48:10] <eric_unterhausen> you see cubes with facing marks on them in shops without a mill
[02:48:30] <CaptHindsight> milling on a lathe
[02:48:34] <zeeshan> i think i forgot to mention a key thing
[02:48:41] <zeeshan> you're starting off with round stock of any size you want
[02:48:42] <eric_unterhausen> no 4 jaw chuck?
[02:48:51] <zeeshan> you can use a 4 jaw
[02:48:56] -!- Tecan [Tecan!~fasdf@unaffiliated/unit41] has joined #linuxcnc
[02:49:01] <CaptHindsight> no chuck just for extra difficulty
[02:49:05] <zeeshan> hjaha
[02:49:12] <eric_unterhausen> face, flip, face, etc
[02:49:16] <zeeshan> exactly!
[02:49:23] <zeeshan> guess how many people got that question right?
[02:49:29] <eric_unterhausen> 1?
[02:49:32] <Valen> i was thinking there was some trick answer?
[02:49:33] <zeeshan> 4/120
[02:49:59] <eric_unterhausen> my boss had to make a cube with a chisel
[02:50:07] <Tom_itx> you'll have to do better than that...
[02:50:09] <zeeshan> haha that's intense
[02:50:21] <Valen> I'd bolt the bigass fly cutter into the chuck, bolt the block in in place of the tool post and just wind it past
[02:50:26] <zeeshan> Tom_itx: cmon it's a trick question if many of the class couldnt get it
[02:50:29] <eric_unterhausen> he still likes the idea, I have never figured out why

[02:50:55] <eric_unterhausen> no, had no mill
[02:51:14] <Valen> eric_unterhausen: that doesn't involve a mill
[02:51:23] <Valen> put a milling bit into the lathe chuck
[02:51:37] <Valen> one of my friends was doing apprenticeship at qantas, first job was to make a 25mm (1 inch) cube
[02:51:43] <eric_unterhausen> I was just addressing the part that we were experienced
[02:51:55] <jdh> Valen: with a file?
[02:51:56] <Valen> thing is if there was any defect it would be rejected
[02:52:03] <zeeshan> haha with a file
[02:52:05] <zeeshan> i'd kill myself
[02:52:08] <Valen> jdh: they were told they could use any tool
[02:52:21] <Valen> the correct answer was use a file ;->
[02:52:33] <Valen> anything else left marks in the job
[02:52:35] <CaptHindsight> and he had to start with a 10' length of rusty plumbing pipe

[02:53:02] <jdh> real men would make the file first
[02:53:22] <CaptHindsight> when I was a kid I wish we had files...

[02:53:37] <zeeshan> im proud of this attachement i made
[02:53:38] <jdh> yeah, we just had shark rocks
[02:53:43] <CaptHindsight> just rough and smooth rocks

[02:55:00] <jdh> no tig, just a cable and a bank of car batteries
[02:55:05] <zeeshan> i wanted maximum penetration
[02:55:05] <CaptHindsight> just think about if you had to start out with no tools and go from stone age to a 1" perfect metal cube
[02:55:11] <zeeshan> undercut is acceptable
[02:55:20] <Valen> I want to make a book on that CaptHindsight

[02:55:37] <CaptHindsight> Valen: neat
[02:55:48] <zeeshan> Tom_itx: damn
[02:55:58] <CaptHindsight> based on todays info, how fast could it be done?
[02:56:00] <Tom_itx> i did one on my sherline
[02:56:02] <zeeshan> that looks like a lot of facing and boring
[02:56:16] <Valen> nfi, would be a job of work to find out
[02:56:25] <Valen> I was thinking kickstarter
[02:56:41] <Valen> but you need to do stuff like, how do you mine iron
[02:56:44] <Valen> and nickel
[02:56:47] <Valen> and molybdinum
[02:57:04] <Valen> tungsten if you want light bulbs
[02:57:07] <CaptHindsight> is food delivered or caught?
[02:57:18] <Tom_itx> hunted
[02:57:27] <Valen> I was thinking how you start a colony basically
[02:57:27] <eric_unterhausen> I am cutting squares on my cnc lathe
[02:57:42] <Tom_itx> i like watching wild alaska
[02:57:46] <zeeshan> eric_unterhausen: broaching? :D
[02:57:54] <CaptHindsight> looking back it was amazing how much time was spent on just getting food
[02:57:57] <eric_unterhausen> grinding the outside
[02:57:58] <zeeshan> or that funy offset tool
[02:57:59] <Valen> start off with around 40 people, have a breeding plan to maintain diversity etc then grow from there to a ~ 1930's society
[02:58:06] <theorbtwo> Gingery, for crazier people...
[02:58:36] <CaptHindsight> so 35 managers and 5 workers
[02:58:57] <zeeshan> serious question
[02:59:00] <julby0> breeding plan: 39 women and me
[02:59:02] <Valen> I wonder if sea water extraction might be the best way to get everything other than steel and Al
[02:59:11] <zeeshan> i have a 3hp vfd do you guys think putting it in the same enclosure as all the stepper drivers is a bad idea?
[02:59:21] <Valen> I was thinking you could also use it as your zombie survival handbook
[02:59:37] <Valen> or robopocalypse
[02:59:39] <eric_unterhausen> zeeshan, depends on your stepper ps
[02:59:43] <Valen> you know, choose your own disaster
[02:59:46] <zeeshan> ps?
[02:59:48] <zeeshan> power supply?
[02:59:48] <CaptHindsight> why do zombies need to survive? :)
[02:59:51] <eric_unterhausen> yes
[02:59:56] <zeeshan> im using 72v 8amp switched supplies
[02:59:58] <theorbtwo> CaptHindsight: The pilgrims did that. That's most of why they almost starved.
[03:00:04] <zeeshan> 2 of em
[03:00:48] <theorbtwo> Valen: I rather doubt it? Has anybody managed to make seawater extraction pay off?
[03:01:27] <CaptHindsight> the problem with lots of tech like water extraction is paying for the large plant
[03:01:45] <CaptHindsight> that is how government projects pay off in the long run
[03:02:08] <Valen> not in comparison with a petrochemical powered global economy, but if your after 50 grams of tungsten to make light bulbs trekking a few hundred Km by foot and trying to mine is probably going to be harder than hurling electricity at the ocean ;->
[03:02:08] <CaptHindsight> but not for capitalist investors
[03:03:38] <CaptHindsight> maybe next time people will decide to do something about sociopaths, selfishness and greed
[03:05:25] <zeeshan> http://i130.photobucket.com/albums/p252/turbozee84/C1E223E1-4C0C-4255-99C5-2590B91C1742_zpsdjuo7tvp.jpg
[03:05:28] <zeeshan> see that big ass vfd
[03:05:45] <zeeshan> for some reason i feel like itll destroy the signal coming from the parallel port to the control side of the stepper drivers
[03:05:49] <jdh> CaptHindsight: we elect them.
[03:05:58] <Valen> use shielded cable on it
[03:06:09] <zeeshan> yes
[03:06:11] <Valen> and look at an EMI filter on the power side of it if you have problems
[03:06:12] -!- FinboySlick has quit [Quit: Leaving.]
[03:06:21] <zeeshan> but the very ends that connect to the stepper will have unshilded portion
[03:06:23] <Tom_itx> yeah your job is to make it all quiet
[03:06:33] <Valen> keep the distance from the pport to the stepper driver shortish
[03:06:43] <zeeshan> should i put a faraday cage around the vfd?
[03:06:44] <Valen> and thats not a paticularly weak signal anyway so should be ok
[03:06:46] <Valen> nah
[03:07:08] <zeeshan> okay ill put them on opposite ends of the enclosure
[03:07:15] <zeeshan> so they'll prolly end up having at least 12" of space
[03:07:16] <CaptHindsight> jdh: gullible
[03:07:23] <Valen> its when you have a limit switch line thats connected to 6 switches running around the whole mill that you have issues
[03:07:35] <Valen> keep the distance from the pport itself to the stepper driver short if you can
[03:07:51] <Valen> and i belive that pport cables can come in shielded flavours?
[03:07:56] <zeeshan> this thing will have 4 limit switches
[03:08:04] <zeeshan> proximity inductive kind
[03:08:13] <Valen> thats where you are more likley to have noise issues
[03:08:22] <zeeshan> so ill get nuisance tripping?
[03:08:25] <Valen> the wire is the antenna, the longer the antenna the more noise it recieves
[03:08:34] <Valen> possibly
[03:08:35] <CaptHindsight> zeeshan: big reprap? :)
[03:08:38] <zeeshan> yea but those will be wired using alarm cable
[03:08:40] <zeeshan> which is shielded
[03:08:42] <Valen> depends on the phase of the moon
[03:09:16] <zeeshan> CaptHindsight: lathe
[03:10:22] <CaptHindsight> was the ML server stuck, I just got a dozen from 12 hours ago
[03:10:45] <zeeshan> do they make some sort of tool
[03:10:50] <zeeshan> to measure noise
[03:10:51] <CaptHindsight> must be mine they are all hours apart
[03:11:03] <zeeshan> basically a coil connected to an oscilliscope? :)
[03:12:08] <Valen> i wouldn't worry about it until you have a problem with it
[03:12:17] <zeeshan> i'd hate to have to remake the enclosure :{
[03:12:21] <Tom_itx> i used shielded wire on everything
[03:12:33] <CaptHindsight> http://www.bloomberg.com/news/2014-01-28/customs-drone-fleet-grounded-after-predator-goes-down.html
[03:12:44] <zeeshan> shielded wire doesnt shield the ends of the wire that go into the driver or breakout board though
[03:13:00] <Tom_itx> no but it dies there
[03:13:07] <zeeshan> from what ive seen most people use literally aluminum foil wrapped around their wires
[03:13:15] <zeeshan> and on top of that there is a pvc/plastic jacket
[03:13:21] <Tom_itx> ground one end or you'll get ground loops
[03:13:35] <zeeshan> http://i1274.photobucket.com/albums/y437/inchoice/1_zps3b02bbf0.jpg
[03:13:36] <zeeshan> that stuff
[03:13:46] <Tom_itx> i got a spool of shielded wire for my steppers
[03:14:02] <zeeshan> ground one end to the chassis?
[03:14:08] <Tom_itx> yes
[03:14:29] <Valen> ideally you want all the grounds in your system to be a star
[03:14:34] <CaptHindsight> flying cnc machines
[03:14:49] <zeeshan> star as in meet together at one point?
[03:14:53] <Valen> IE they all come back to one point
[03:14:54] <zeeshan> in a star pattern?
[03:14:54] <Tom_itx> similar to what you posted
[03:14:55] <Valen> with no loops
[03:14:57] <Tom_itx> only more wires
[03:14:58] <zeeshan> ah
[03:15:10] <Tom_itx> zeeshan all grounds come back to a single point
[03:15:19] <Tom_itx> not point to point to point
[03:15:19] <zeeshan> see the stepper casings also have a ground
[03:15:26] <zeeshan> i was going to ground that on the chassis too
[03:15:36] <zeeshan> i have zero experience with grounding control wire ;p
[03:15:44] <Valen> dont worry about it too much
[03:15:57] <Tom_itx> yeah, not unless you have noise problems
[03:15:59] <Valen> just ground one end of stuff ;->
[03:16:02] <zeeshan> okay
[03:16:08] <Valen> odds are you will be fine ;->
[03:16:21] <zeeshan> i just know this type of vfd is really noisey
[03:16:26] <zeeshan> you can hear it.
[03:16:33] <Valen> we had a VFD that sprayed so much noise the neighbours would complain about their radios getting bad
[03:16:33] <zeeshan> it runs at like 14khz
[03:16:34] <CaptHindsight> the suggestions just makes things more reliable
[03:16:41] <zeeshan> hahah
[03:16:48] <Valen> didn't bother our linear scale based servo system
[03:17:02] <zeeshan> im sure one day the hydro company is going to be pissed at me
[03:17:08] <Valen> and that was only TTL not differential drive from the scales
[03:17:10] <zeeshan> running 3 vfds together with no line reactors
[03:17:20] <zeeshan> :)
[03:17:29] <Valen> if they have power factor correction on the inputs then that should be ok
[03:17:35] <zeeshan> industrials/commercial places get OWNED by the power company for that
[03:17:41] <Valen> some of them will even the cheap ones because they can pull more power
[03:17:53] <Valen> they also pull eleventy billion jiggawatts
[03:18:13] <zeeshan> okay here's one more twist to the enclosure
[03:18:34] <zeeshan> i'd like to also on the back face of the enclsore across where all the vfds, breakoutboard, index pulse card, stepper drivers are mounted
[03:18:44] <zeeshan> i'd like to mount a motherboard there
[03:18:59] <zeeshan> and it's power supply. and a sata hd
[03:19:09] <Valen> hard part of that is mounting pci cards
[03:19:15] <zeeshan> no pci cards
[03:19:20] <Valen> (yet)
[03:19:21] <zeeshan> it's got onboard video and parallel port
[03:19:36] <Tom_itx> zeeshan, here's my sherline control pannel: http://tom-itx.dyndns.org:81/~webpage/cnc/psu/psu_index.php
[03:19:48] <Tom_itx> maybe a bit overkill

[03:29:08] <zeeshan> i have tons of scrap pieces from that eaton job
[03:29:09] <Tom_itx> i got the box off ebay for next to nothing
[03:29:26] <Valen> mesa have mounts?
[03:29:48] <Tom_itx> sure do
[03:29:55] <Tom_itx> i found something else i wanted to get...
[03:30:00] <Valen> are they different in any way from mbo mounts?
[03:30:01] <Tom_itx> screw terminal power strips
[03:30:18] <Tom_itx> for the box rail mounts... i forget what they're called
[03:30:46] <zeeshan> http://www.thomasnet.com/articles/image/standoff.jpeg
[03:30:52] <zeeshan> think those are overkill? :p
[03:31:46] <Tom_itx> a bit
[03:32:11] <Tom_itx> Valen, DIN rail mounts
[03:32:31] <Tom_itx> and their common block are both listed at the top of their daughter card page
[03:32:51] <zeeshan> im so used to designing enclosures for 600v
[03:33:02] <zeeshan> im thinking my puny little 110v/220v needs the same requirements
[03:33:20] <zeeshan> infact, the pcbs dont even see higher than 12v
[03:33:48] <zeeshan> so 1/4" stand off would be more than adequate without needing any mylar.
[03:35:00] <Tom_itx> http://www.ebay.com/itm/RITTAL-AE1380-ENCLOSURE-STEEL-GREY-/121245256375?pt=LH_DefaultDomain_0&hash=item1c3ac7cab7
[03:35:04] <Tom_itx> that's the enclosure
[03:35:10] <Tom_itx> but i didn't pay near that for it
[03:35:26] <zeeshan> i need 10" deep minimum
[03:35:27] <zeeshan> ;[

[03:35:43] <zeeshan> ill look through it
[03:36:23] <Tom_itx> os1r1s mostly for playing
[03:36:54] <os1r1s> Tom_itx: My two ... http://mounicou.com/cnc/cncenc.jpg
[03:37:05] <zeeshan> cute
[03:37:06] <zeeshan> haha
[03:37:07] <os1r1s> Though I just replaced the motor on the Taig with a sherline motor
[03:37:15] <Tom_itx> i think i've seen those
[03:37:23] <os1r1s> Tom_itx: Prolly
[03:37:29] <zeeshan> os1r1s: why cant you use flood coolant?
[03:37:35] <zeeshan> all you need is a base
[03:37:42] <zeeshan> and a bucket on the buttom of your table
[03:37:43] <os1r1s> Tom_itx: I want to build one of the toolchangers for the mill
[03:38:03] <os1r1s> zeeshan: Too much risk/mess for an indoors/upstairs workshop
[03:38:19] <zeeshan> did you build those enclosures?
[03:38:20] <os1r1s> Though I may reconsider at some point :P
[03:38:23] <os1r1s> zeeshan: Yeah
[03:38:27] <zeeshan> they're fucking nice!
[03:38:33] <os1r1s> zeeshan: 1/4 lexan panels
[03:38:34] <jdh> that's a lot of extrusion
[03:38:42] <os1r1s> Should handle impact well if it gets any
[03:38:56] <zeeshan> its not like you're going to be running 2" end mills
[03:38:57] <zeeshan> :P
[03:39:04] <zeeshan> but those are nicely built.
[03:39:06] <os1r1s> haha. Right
[03:39:14] <os1r1s> I'm more worried about work flying
[03:39:20] <os1r1s> zeeshan: Thx
[03:43:56] <CaptHindsight> anyone ever weld ~1mm aluminum with a MIG? extra points for not using a spool gun
[03:44:12] <Tom_itx> nope
[03:44:18] <zeeshan> almost impossible mate
[03:44:23] <Tom_itx> i saw 2 pop cans welded together though
[03:44:25] <Tom_itx> using tig
[03:44:32] <CaptHindsight> yeah TIG
[03:44:37] <Tom_itx> :)
[03:44:45] <zeeshan> tig can handle that easily
[03:44:55] <zeeshan> mine goes down to 5amp which means you can weld down to .005 thick metal
[03:44:58] <CaptHindsight> I never tried to see how light on aluminum I can go
[03:45:08] <CaptHindsight> with a MIG
[03:45:09] <zeeshan> you might be able to use aluminum solder
[03:45:24] <CaptHindsight> TIG is the right tool

[03:52:42] <Tom_itx> alot of aluminum

[03:53:06] <zeeshan> damn
[03:53:07] <Tom_itx> no not really
[03:53:16] <zeeshan> well aluminum is like 2bux a pound usually

[03:53:38] <zeeshan> CaptHindsight: that alumiweld is that brand i've seen in a lot of youtube videos
[03:54:03] <CaptHindsight> lower cost than some of my TIG rods
[03:54:15] <zeeshan> if u have a tig
[03:54:18] <zeeshan> why are you brazing!
[03:54:24] <zeeshan> is it dc only?
[03:54:54] <CaptHindsight> no, I was just wondering if anyone tried to MIG light aluminum
[03:55:00] <zeeshan> ah
[03:55:09] <CaptHindsight> just to see how light they can go
[03:57:12] <zeeshan> curious question of the day
[03:57:23] <zeeshan> what's the largest cutting tool you guys own?
[03:57:38] <Valen> 90mm face mill i think
[03:57:40] <Tom_itx> damn. own or have used?
[03:57:43] <zeeshan> own
[03:57:51] <Valen> or the 15A bandsaw?
[03:57:54] <Tom_itx> well i'm out... i have a sherline now
[03:57:57] <CaptHindsight> http://www.youtube.com/watch?v=U1gWaGZ-nks starts around 2:00 TIG Welding Pop Cans!!
[03:58:02] <zeeshan> it has to be a cutting tool
[03:58:05] <zeeshan> not a machine ;p
[03:58:14] <Valen> the blade from the bandsaw?
[03:58:16] <zeeshan> haha
[03:58:53] <Tom_itx> overall probably a 6" shell mill or the 2 & 3" insert cutter drill bits we used
[03:59:08] <zeeshan> gotta own em ;[
[03:59:10] <Valen> Tom_itx: (I wouldn't want to use it on the 24Krpm spindle we have now though lol)
[03:59:25] <Tom_itx> the bits were for titanium parts
[03:59:43] <zeeshan> mine is a 2.5" drill bit
[03:59:50] <zeeshan> it came with my lathe lol
[03:59:53] <skunkworks> we have a 12" facing mill
[03:59:55] <zeeshan> i don't think ill ever use it
[04:00:03] <zeeshan> 12" face mill. holy cow
[04:00:51] <Tom_itx> for the part 3 from the left in the Titanium section: http://clearwateren.com/gallery.php

[04:38:05] <PetefromTn> I have heard parts can be really expensive tho.

[05:08:08] <PetefromTn> Dropped my FZR1000R there a couple years back luckily I survived and the bike only needed a new mirror and windscreen.
[05:10:10] <os1r1s> PetefromTn: I think this was a spot on the tail where we stopped ... http://gallery.mounicou.com/Travel/Asheville-2010/i-fCjcVRK/0/L/IMG_0222-L.jpg
[05:10:37] <PetefromTn> Yup the overlook. Been there many times.
[05:10:52] <PetefromTn> It is maybe ten to twelve minutes from my house LOL.
[05:11:16] <os1r1s> That was when they had closed one end due to the landslide. So traffic was light
[05:12:05] <PetefromTn> I went thru there with the Fiero Club awhile back before I sold my car to get my wife a newer SUV. LOL
[05:13:41] <PetefromTn> Spent much of the afternoon playing with CamBam trying to learn my way around the program. got a bunch of things working right but still cannot figure out how to turn coolant on and off LOL.
[05:13:47] <CaptHindsight> I was just reading about the Tail the other day. Why is it considered so treacherous?
[05:14:03] <CaptHindsight> land slides?
[05:14:07] <eric_unterhausen> because people are stupid
[05:14:31] <eric_unterhausen> I'm a good driver == I can floor the gas pedal to most people
[05:15:28] <eric_unterhausen> there is a road in California that was fine until all the motorcyclists and car drivers use it to show how badly they drive
[05:15:43] <eric_unterhausen> mullholland canyon I think
[05:16:18] <Jymmm> what about mulholland drive?
[05:16:23] <eric_unterhausen> that's it
[05:16:46] <eric_unterhausen> there's a guy that makes a living off of people crashing on it
[05:16:57] <Jymmm> Nah, more of a constant collection of stupidity for the cops is all.
[05:17:17] <PetefromTn> The road is really tight and twisty. 118 turns in 11 miles.
[05:17:19] <Jymmm> Especially being just Northof Hollywood

[05:17:42] -!- heathman_ has quit []
[05:17:45] <PetefromTn> The biggest issue is there is NO runoff area anywhere so if you do manage to lose it like I did you wind up going down a cliff into the trees..
[05:18:13] <PetefromTn> If you go off on the high side of the cliff you still hit trees.
[05:18:39] <PetefromTn> The NC side of the road is also not that smooth and can cause issues with traction.
[05:18:51] <eric_unterhausen> haha, the cops sit in the same place as the utube guy
[05:19:03] <PetefromTn> People are air lifted out of there almost daily during the summer.
[05:20:07] <eric_unterhausen> bugatti driver can affort the ticket I guess
[05:20:16] <PetefromTn> I was actually doing pretty good but lost the front end for just a second and by the time I gathered it up again I was going across the damn median in the next turn. nearly hit a van and ran into the grass on the other side.
[05:20:31] <PetefromTn> I was pretty lucky considering.
[05:20:43] <PetefromTn> The funny thing is I was not going all that fast.
[05:20:57] <PetefromTn> It is just a complex road.
[05:21:18] <PetefromTn> It is not really all that fun to ride on it with a bike because you are constantly working to maintain your line.
[05:21:54] <eric_unterhausen> if you lose it on mulholland, you get to relive the first scene from mulholland falls
[05:22:06] <PetefromTn> There are some GORGEOUS roads around here that are long and twisty but have kinda fast smooth arcs that are much more enjoyable to ride on.
[05:22:41] <os1r1s> PetefromTn: The skyway is nice in that respect
[05:22:51] <os1r1s> Some fast sweepers
[05:22:53] <eric_unterhausen> there is a road near my mother's in Virginia that has turns so tight that it's a bit scary
[05:23:09] <PetefromTn> I live right near the foothills parkway..it is quite nice and the view is pretty incredible.
[05:23:59] <PetefromTn> There are lots of roads like that around here, the dragon is just one of them and is the longest most famous one.
[05:24:12] <PetefromTn> People come from around the world to ride this road believe it or not.

[05:26:45] <PetefromTn> That actually looks like fun LOL..
[05:27:16] <CaptHindsight> http://www.zuzafun.com/dangerous-roads the last one is crazy
[05:27:32] <CaptHindsight> I wonder where that bridge is
[05:27:47] <PetefromTn> Just searched about the coolant flow in CamBam. I guess it is not setup for it. You have to make an add on Machining operation that puts a header or footer under each machining op to get it done.
[05:28:45] <PetefromTn> Either that or mod the post processor to install the code permanently.
[05:28:51] <Valen> https://maps.google.com.au/maps?q=Little+Brown+Mountain,+Bemboka,+New+South+Wales&hl=en&ll=-36.608431,149.476032&spn=0.059046,0.132093&sll=35.131521,-81.405085&sspn=0.030079,0.066047&oq=Brown+Mountain+bemb&hnear=Little+Brown+Mountain&t=m&z=14 is the exciting road we have when we go on holidays
[05:28:59] <Valen> it drops about a km over that distance ;->
[05:29:48] <PetefromTn> Kinda odd that a Cam program does not have native coolant support huh.
[05:30:08] <eric_unterhausen> huh
[05:30:44] <PetefromTn> uh huh
[05:30:58] <eric_unterhausen> huh is the best word ever
[05:31:22] <PetefromTn> you are some kinda smartass huh
[05:31:32] <eric_unterhausen> huh
[05:31:53] <Jymmm> Better to be a smartass than a dumbass.
[05:32:13] <eric_unterhausen> i dunno, lots of times there isn't much space between
[05:32:27] <Jymmm> eric_unterhausen: Huh?
[05:32:34] <Jymmm> ;)
[05:33:30] <CaptHindsight> Valen: streetview works on that Hywy
[05:34:58] <CaptHindsight> but the cars are on the wrong side of the road :)
[05:35:04] <PetefromTn> I would imagine there are some beautiful sights around there LOL
[05:35:56] <CaptHindsight> I wish streetview had a play button where it would just drive you down the road without having to click the buttons
[05:36:16] <PetefromTn> That would be fun. take a drive from your easy chair.
[05:36:49] <eric_unterhausen> ya, driving would be nice
[05:36:59] <PetefromTn> I wonder if the lookout on foothills parkway lets you go up there on streetview.
[05:37:06] <eric_unterhausen> especially since it doesn't always drop you where you put the circle
[05:37:43] <eric_unterhausen> when I was a teenager, I was following a friend and did a 180 on a steep mountain road.
[05:37:55] <eric_unterhausen> had to drive to the bottom because there was no place to turn around
[05:38:28] <eric_unterhausen> turns out my friends car had better tires
[05:38:54] <eric_unterhausen> still can't believe I was so lucky that I didn't hit anything
[05:39:42] <eric_unterhausen> only way to do a u turn is at speed because the road is too narrow otherwise
[05:43:05] <PetefromTn> If you google yourself down the foothills parkway in tennessee starting from the walland hwy towards the dragon there are some amazing lookouts that you can view along the way and there is a lookout on I think the third one that has the lookout tower. I am trying to get there now to see if you can view it.
[05:43:35] <PetefromTn> It is quite a view they say you can see three or four states from that point or something like that.
[05:49:02] <PetefromTn> Come to think of it maybe it is the fifth or sixth LOL
[05:53:54] <PetefromTn> Aah it does not seem to let you walk up the path to the look rock. That sucks. I gotta hit the sack talk tomorrow folks. Peace

[07:43:43] <s1dev> thanks I'll do that
[07:44:36] <archivist> it is a slightly odd one as it has a quick clamp setup for production work
[07:45:25] <s1dev> and do you know anyone who's modified a tailstock to fit a different lathe?
[07:45:30] <archivist> I also got a couple at a local factory close down for work
[07:46:31] <archivist> a good tail stock comes apart in the middle to slide sideways, just make a new base

[08:25:26] <Jymmm> elaborate and provide context
[08:26:09] <Jentrep> it is a directory name in the linuxcnc source base
[08:26:24] <Jentrep> it contains files like emc.h and emcpos.h
[08:26:38] <Jentrep> emc being the old name for linuxcnc i guess
[08:26:51] <Jentrep> idk anything about linuxcnc :P
[08:26:58] <Jentrep> I am just studying the source :P
[08:29:14] <Jentrep> what would pose math be?
[08:29:20] <Jentrep> there is a file named posemath.h
[08:29:23] <Jentrep> Is that position?

[13:09:52] <Valen> probably
[13:13:44] <Loetmichel> valen thats like me cutting ferrite plates to size... -> http://www.cyrom.org/palbum/main.php?g2_itemId=13525 ;-)
[13:14:08] <Valen> I dunno.... i think i came out blacker ;-P
[13:14:23] <Valen> how do you cut ferrite without it doing bad things btw?
[13:14:39] <Tom_itx> carefully
[13:14:52] <Loetmichel> with a diamond wheel
[13:14:57] <Loetmichel> .. and careful ;-)
[13:15:17] <Tom_itx> i cut some with a cutoff wheel but it took a while
[13:15:40] <Loetmichel> diamond cutoff disks rule for that
[13:15:54] * Tom_itx feels Loetmichel came out entirely too clean
[13:15:57] <Loetmichel> like you see in the photo ;-)
[13:16:05] <Loetmichel> some experience isnt that bad, either ;-)

[16:51:11] <ReadError> couldnt find anything that actually had a following yet

[16:51:34] <CaptHindsight> ReadError: yeah, what I found so we had to make it
[16:54:00] <CaptHindsight> ReadError: we have to inspect the surface of a non-planar object, look for defects and then move a tool into that area and perform repairs

[16:56:21] <ReadError> I thought it was a pick-n-place
[16:56:24] <CaptHindsight> we integrated a zoom microscope so it can scan and then zoom in for the repair
[16:56:38] <CaptHindsight> it could easily be adapted for pick-n-place
[16:56:51] <CaptHindsight> even on non-planar surfaces
[16:57:06] <FinboySlick> CaptHindsight: Prep as in buff the surfaces clean?
[16:58:25] <CaptHindsight> FinboySlick: solvent clean and scuff, depending on the plastic you might be able to solvent weld it, but that would only be as strong not more than originally
[16:59:51] <CaptHindsight> ReadError: the makerspace in Chicago made some open pick-n-place PS1

[17:31:03] <diginet0> CaptHindsight: network is about to go down so I might disconnect any moment now
[17:31:40] <CaptHindsight> linear servo motor is just that, a linear positioner could have a linear motor or lead/ballscrew, belt, pneumatic or hydraulic cylinder
[17:32:13] <diginet0> CaptHindsight: but does LinuxCNC take care of the servo algorithms?
[17:32:20] <CaptHindsight> yes
[17:32:55] <CaptHindsight> I use linear motors all the time with Linuxcnc btw
[17:33:10] <diginet0> does linear servo-ing differ from rotary? I've read some papers that have all of these really elaborate control loops, much more than say PID
[17:34:09] <CaptHindsight> coil motor and encoder feedback

[17:35:29] <CaptHindsight> PID
[17:35:34] <diginet0> ah
[17:35:38] <diginet0> also, does that mean that LinuxCNC could use DC motors with encoders?
[17:36:06] <CaptHindsight> braking using the forcer or a secondary brake?
[17:36:45] <diginet0> well what I mean is that if you stop applying power to leadscrew it just stops right there, I don't think that happens with a linear motor
[17:36:54] <CaptHindsight> yes you can use DC motors with an encoder
[17:37:25] <diginet0> do people do that often? how does it compare in terms of performance to using real servos?
[17:37:41] <CaptHindsight> if you care how it stops then you don't stop them by just cutting the power
[17:37:50] <diginet0> (sorry for my probably dumb questions, and thanks so thaks so much)
[17:37:57] <CaptHindsight> it depends on the motor design
[17:38:03] <skunkworks> diginet0, it applies opposite electrical force.. same as with a dc servo motor
[17:38:09] <CaptHindsight> BLDC vs brushed DC
[17:38:15] <diginet0> skunkworks, CaptHindsight ahhhh okay

[17:39:34] <CaptHindsight> heh, you can buy both on ebay for cheap, but if it's just for fun
[17:40:03] <CaptHindsight> lots of missed-matched stuff there
[17:40:04] <diginet0> CaptHindsight: define cheap though, I define cheap as in sub-$100
[17:40:15] <CaptHindsight> yeah <$100

[17:40:25] <diginet0> really? complete assemblies?
[17:40:58] <diginet0> the other tricky thing is motor controllers, designs abounds for BLDC controllers, but not so much for linear motors
[17:41:54] <diginet0> the ironless designs are nice because you don't need to worry about the laminated "stators"
[17:42:20] <CaptHindsight> you could make a coil like a BLDC for a magnet track
[17:43:03] <diginet0> oh I know, you just makes the coils and encase them in some sort of epoxy, and hope the thing that doesn't catch on fire ;)
[17:43:17] <CaptHindsight> the real science in making the motors is the materials
[17:43:22] <diginet0> indeed
[17:43:33] <diginet0> I've seen some thermally conductive epoxies I might try out for it
[17:43:37] <diginet0> CaptHindsight: what kind of repeatability/accuracy do you get?
[17:44:17] <diginet0> in your linear motor setup I mean
[17:45:42] <CaptHindsight> we can get submicron in controlled environments, but setups with 0.5m travel are easily few microns with 2G accell/decell
[17:46:01] <diginet0> wow, that's impressive
[17:46:16] <diginet0> by controlled environments, do you mean like climate control?
[17:46:26] <CaptHindsight> yes, in a box
[17:46:38] <diginet0> ahh, cool
[17:46:55] <diginet0> can LCNC work with LVDTs for the linear "encoders?"
[17:48:34] <CaptHindsight> http://imagebin.org/287237 this one is <5um
[17:48:51] <skunkworks> if the lvdt ouputs something linuxcnc can read (quadature for one..)
[17:49:18] <diginet0> CaptHindsight: that's awesome, what do you use it for?
[17:49:25] <zeeshan> CaptHindsight: you should start a photobucket account
[17:49:26] <diginet0> skunkworks: ah okay
[17:49:31] <zeeshan> so i can surf through your pictures :p
[17:49:36] <skunkworks> if lvdt you mean resolver - mesa and pico has hardware that will read them directly

[17:52:33] <diginet0> skunkworks: maybe that's it, I just meant something to measure the linear position
[17:52:44] <IchGuckLive> Atlanta 1cm snow state of emergency !
[17:52:45] <CaptHindsight> diginet0: you don't have to worry about epoxies unless you plan on tweaking to get the most out of it, you can just use a spray or dip clear
[17:53:15] <CaptHindsight> IchGuckLive: yeah, any snow down south and it's a disaster
[17:53:18] <diginet0> CaptHindsight: ahh, I just meant encase them in something so that their position is stable
[17:53:19] <jdh> IchGuckLive: more that that... people have been stuck on the interstate since yesterday
[17:53:37] <CaptHindsight> IchGuckLive: like +42 C in Germany
[17:53:38] <diginet0> CaptHindsight: we get the tiniest bit of sleet here in Houston and the whole city shuts down
[17:53:40] <diginet0> it's insane
[17:53:43] <IchGuckLive> jdh: most school kids
[17:54:02] <IchGuckLive> CaptHindsight: why did there the govener not interfer
[17:54:05] <diginet0> on a somewhat unrelated noted, I see 5-axis CNCs a lot, but not so often 6-axis ones, is there a reason for that?
[17:54:35] <IchGuckLive> diginet0: 6th axis are only for spare partrs
[17:54:46] <jdh> we got an inch or so of ice then snow on top. Most everything is shut down.
[17:54:48] <IchGuckLive> 5axis can do the most
[17:55:47] <diginet0> IchGuckLive: ahh, so the basically there's diminishing returns?
[17:55:55] <IchGuckLive> diginet0: the 6th axis offen used for tool correction only
[17:56:23] <diginet0> I see.
[17:56:48] <diginet0> yeah, my project is a 3D printer, so obviously I don't need rotational axes, but I'd like to build a multiaxis CNC one day
[17:56:49] <IchGuckLive> also the Double Z gives you a wonderfull drilling in all angels
[17:57:02] <diginet0> IchGuckLive: what is double Z?
[17:57:03] <IchGuckLive> diginet0: why homebuild
[17:57:12] <IchGuckLive> 3D
[17:57:19] <diginet0> IchGuckLive: which? the 3D printer or the CNC?
[17:57:28] <IchGuckLive> there are cheep with all goods inside
[17:57:40] <IchGuckLive> 3d print
[17:57:50] <diginet0> mostly because I'm disastisfied with most of the offerings, and controlling with LinuxCNC would be vastly superior to the others
[17:57:53] <IchGuckLive> and the parts to order are so cheep now
[17:57:59] <diginet0> also to learn/experiment
[17:58:16] <diginet0> it seems silly to me to calculate tool paths using an 8-bit micro
[17:58:22] <IchGuckLive> the 3D printers in modern time do nort se codes
[17:58:31] <IchGuckLive> stl and print
[17:58:41] <CaptHindsight> I love Enco, they ship so fast my orders get here before they send me the tracking info
[17:58:43] <IchGuckLive> its that easy no G-code for users
[17:59:01] <diginet0> yeah but like most firmwares can't even do true curves
[17:59:47] <diginet0> plus, I want to do a few things different, like a heated build chamber (not just platform), so why even bother because it'd be easier to just do it myself
[18:00:03] <diginet0> if I'm going to change everything about it, why even bother buying one?
[18:01:18] <IchGuckLive> agree
[18:01:24] <diginet0> IMO, the way reprap does it is incredibly arcane
[18:01:29] <IchGuckLive> you got a look on freesculpter ex1
[18:01:58] <IchGuckLive> it got all you talking about
[18:02:04] <diginet0> IchGuckLive: sadly, I don't speak German :(

[18:02:19] <IchGuckLive> continent
[18:02:29] <diginet0> IchGuckLive: N. America, Texas specifically
[18:02:42] <diginet0> I have a vague goal to learn German one day though :P
[18:03:18] <IchGuckLive> Obama anounced today 1.5 Bilion Dollars for our town from the US military budget

[18:03:51] <IchGuckLive> Ramstein Kaiiserslautern Weilerbach
[18:04:09] <diginet0> ah, is there a military base there or something?
[18:04:20] <jdh> he must not know you can't buy votes there.
[18:04:59] <diginet0> jdh: it does bother me how much Obama panders to the EU
[18:05:49] <diginet0> I do love though, what Merkel said about the NSA thing, "Like the Stasi, just less competent"

[18:07:47] <IchGuckLive> and every woundet world wide of us military is shipped in
[18:08:00] <mozmck> it's amazing how often I see some new article about how there's a bug in how the voting machines count votes.

[18:08:14] <diginet0> mozmck: isn't it though?
[18:08:19] <CaptHindsight> what makes anyone think that the counting of the votes here is accurate?
[18:08:37] <CaptHindsight> there is no way to check

[19:23:05] <PetefromTn> I am trying to run a part I designed and setup in CamBam for the first time.
[19:23:29] <PetefromTn> I ran a single operation to test both in air and then in the material and everything went fine.
[19:23:34] -!- pcw_home has quit [Read error: Connection reset by peer]
[19:23:53] <PetefromTn> Now I am trying to run the following operations and the tool needed is tool 23
[19:24:15] <jmasseo> did you configure your tool table in cambam?>
[19:24:18] <PetefromTn> I do not have tool 23 in the tool table and when I try to load the new program it says so and I click okay and it does not load the program
[19:24:32] <PetefromTn> No not using tool offsets in cambam.

[19:25:19] <PetefromTn> I did not however setup this tool because I was planning to just set the zero on the work surface just to test and probably run in air too before I cut anything.
[19:25:34] <PetefromTn> Not sure of the code but I did run it in simulation and it looks good.
[19:26:12] <PetefromTn> Problem is LinuxCNC won't let me open the tool table to setup the new tool now and If I restart LinuxCNC I may lose position possibly.
[19:26:36] <pcw_home> skunkworks: any of the svst configs should have pwm/stepgens/encoders

[19:28:12] <skunkworks> pcw_home, thanks
[19:30:57] <PetefromTn> I ran the first operation which is just a bolt circle drill pattern and everything looks real good so far. Any ideas how to load this tool into linuxCNC without having to restart? I am sure it is something stupid I am missing.
[19:30:59] <CaptHindsight> Amazon is starting slip
[19:31:56] <CaptHindsight> has anyone noticed their countdowns being very inaccurate? "order in the next hour and have it tomorrow"

[19:33:10] <Tom_itx> PetefromTn it should let you edit the tool table
[19:33:25] <Tom_itx> change the tool number in the program if you can't then reload it
[19:34:11] <PetefromTn> I seem to recall someone telling me the the tool table will only load before you do something but I already ran a program here and now It does not seem to want to let me into the tool table.
[19:34:35] <PetefromTn> Too bad you can't click the tool number down below there in axis and change it LOL.
[19:35:07] <Tom_itx> if you don't wanna rerun code, delete it and save the parts then run the parts
[19:35:14] <Tom_itx> until you figure out the tool table
[19:35:32] <Tom_itx> i set my table up with tools that match my cad cam tool list
[19:37:06] <PetefromTn> I set up my tools to match my cad cam tool list as well but I only use the length offsets on the machine. Everything in the cad cam is zero offset that way.
[19:37:16] <Tom_itx> ie: save each tool path as a program
[19:37:30] <Tom_itx> i don't do it that way

[19:37:59] <Tom_itx> i set my tools off a 123 block in a safe zone
[19:38:09] <Tom_itx> gedit
[19:38:09] <PetefromTn> so do I...
[19:38:15] <Tom_itx> then reload the code in lcnc
[19:38:32] <Tom_itx> did it stop at a tool change?
[19:38:42] <PetefromTn> it stopped after the program was finished.
[19:38:55] <Tom_itx> what's left to run then?
[19:39:12] <PetefromTn> Basically this part consists of several machining ops and I only posted code for one initiallly to test with.
[19:39:28] <Tom_itx> so do like i said above
[19:39:34] <Tom_itx> save each tool as a file
[19:39:38] <PetefromTn> Now I want to run the rest of the code in another posting not including the first machining op to finish the part.
[19:39:43] <Tom_itx> until you figure out the tool table
[19:40:06] <PetefromTn> maybe I am not being clear. I understand the tool table and length offsets.
[19:40:26] <PetefromTn> What I cannot seem to do is open the tool table to load a new tool so I can load this program for it.
[19:40:52] <Tom_itx> gedit will edit it
[19:41:08] <PetefromTn> Is there a way to open the tool table without closing linuxCNC axis?
[19:41:10] <Tom_itx> then reload the tool table
[19:41:19] <Tom_itx> from the menu
[19:41:20] <PetefromTn> Okay lemme try that. thanks
[19:41:49] <Tom_itx> it should save any offsets you had set though
[19:44:28] <PetefromTn> It should and this is a closed loop servo system with encoder feedback so I SHOULD be alright but this is a prototype and I don't have much extra material to screw around with right now LOL
[19:44:49] <ler_hydra> does anyone have a rough rule-of-thumb of the amount of tracking error that you'd normally expect for a servo/encoder system? On the order of 10-20 counts when starting/stopping acceleration (IE. high jerk), and more like 5-10 during mild constant-acceleration moves?

[19:52:47] <jmasseo> are they hard or soft rods?
[19:53:23] <jmasseo> drill rod is usually a tool steel of some sort.
[19:53:25] <Tom_itx> drill rod comes water or oil hardened generally
[19:53:38] <Tom_itx> with a price difference
[19:53:51] <CaptHindsight> http://www.use-enco.com/CGI/INSRIT?PMAKA=505-0240
[19:53:58] <CaptHindsight> these are oil
[19:54:01] <jmasseo> yeah, o1, w1, and a2.
[19:54:07] <jmasseo> at my local supply shop
[19:54:18] <jmasseo> but they are usually half hard cold rolled, right?
[19:54:40] <Tom_itx> yeah they're not that hard to start with
[19:54:46] <jmasseo> right
[19:54:49] <jmasseo> they don't ship them annealed
[19:54:56] <jmasseo> so it's the cold roll work hardness
[19:55:07] <jmasseo> oil hardening.
[19:55:20] <jmasseo> good luck heat treating it. :)
[19:55:43] <Tom_itx> not that bad
[19:55:45] <jmasseo> 36" rod is hard to HT w/o warping.
[19:55:53] <jmasseo> the long kiln is hard to find.
[19:56:00] <jmasseo> unless you've got a salt rig
[19:56:40] <archivist> do it vertically and drop into the bath
[19:56:49] <jmasseo> yeah that's the best way to do it
[19:56:53] <jmasseo> if you've got a salt bath setup.
[19:57:08] <jmasseo> that's the dream for home HT'ing. :)

[20:03:58] <CaptHindsight> "Its position feedback control system consists of thousands of software code lines written into the RAPPY PUMP DC motor control board. " :)
[20:04:10] <CaptHindsight> this should obsolete servos
[20:04:27] <PetefromTn> Then when I opened it up the offsets were not right because it was not homed out yet. I got lost in it and whatever I did I lost the zero location now.
[20:05:14] <PetefromTn> Gonna have to try to picup the zero location again now. It really sucks that you gotta remember to open the tool table if you intend to make any adjustments to it before you do anything.
[20:05:46] <PetefromTn> I dunno what causes it to lock it down but if I do not open the tool table upon startup of LinuxCNC it will not open and I cannot make any changes.

[20:18:23] <PetefromTn> Can anyone tell me why you cannot open the tool table at any point in time?
[20:18:32] <Tom_itx> lemme try
[20:20:35] <PetefromTn> I mean what if you break a tool and need to load a new one that is slightly different? If you already started doing something in LinuxCNC it won't let you open it. At least mine won't.

[21:01:36] <PetefromTn> Well I guess I will just scrap this piece and start over.
[21:01:50] <Tom_itx> aww, don't give up so easy
[21:01:58] <PetefromTn> I think the code is good but I wanted to be more careful
[21:02:11] <Tom_itx> what exactly do you need to do?
[21:02:14] <PetefromTn> Oh I am not giving up but I NEED to make this prototype
[21:02:17] <Tom_itx> you ran some code already...
[21:02:30] <PetefromTn> yeah I ran the drilling cycle first op and it went great.
[21:02:37] <Tom_itx> now what?
[21:02:57] <ler_hydra> Ill try asking again ( ;) ) does anyone have a rough rule-of-thumb of the amount of tracking error that you'd normally expect for a servo/encoder system? Maybe something around the order of 10-20 counts when starting/stopping acceleration (IE. high jerk), and more like 5-10 during mild constant-acceleration moves?
[21:04:20] <PetefromTn> I am unfortunately without a good edge finder holer right now so I started this program using a pointer to the middle of a piece of stock and I doubt I can get that zero picked up again by eyeball LOL
[21:04:40] <PetefromTn> I have a nice electronic edge finder here but I need a holder for it.
[21:05:20] -!- tmcw has quit [Remote host closed the connection]
[21:05:24] <PetefromTn> I was just gonna rely on the fact that the machine remembers the offsets and its homing is precise and machine the whole part at one time but in stages.
[21:05:33] <Tom_itx> it's supposed to
[21:05:52] <PetefromTn> Now I screwed up trying to restart linuxCNC and as soon as I homed it out I lost the offset somehow.
[21:06:04] <PetefromTn> Probably my stupidity but it is gone now.
[21:06:43] <PetefromTn> I could try to put my pointer toolholder I occasionally use to locate stuff on round stock and try to carefully pick up the offset again but that is pretty iffy.
[21:06:58] <PetefromTn> I seriously doubt I could get within a couple thousandths.
[21:07:35] <PetefromTn> The hole pattern is in a thin wall that is in a cicle so if it is off even a little it will both not line up and look funky.
[21:07:42] <Tom_itx> may as well finish out with this chunk so you don't scrap more than one
[21:07:54] <PetefromTn> That's why I said I will just scrap it.
[21:08:24] <PetefromTn> I may just try to pick up the offset but it would only be just to try it. I need to get this machined here
[21:08:51] <PetefromTn> Got a bunch of new tooling for this project here and also do not want to break anything LOL.
[21:09:41] <PetefromTn> I think I will try to pick up the center again. I suppose I could rerun the drilling op and go real slow to see if the drill lines up after I pickup the center again.
[21:10:00] -!- tmcw has quit [Ping timeout: 245 seconds]
[21:10:37] <PetefromTn> Kinda pisses me off that I will probably lose this part because I can't open the damn tool table to edit it. It was mentioned that you can open the tool table from the command line how would you do that?

[22:30:37] <CHNCguy> I have a 20hp RPC and runs the spindles good
[22:31:05] <JT-Shop> I can build them in my sleep but my Siemens 611 drive on my BP 308 has tremendous inrush so the drive trips out
[22:31:15] <JT-Shop> I need to find a 20hp motor

[22:31:38] <CHNCguy> I have 2 40hps if u want one?
[22:31:42] <JT-Shop> I have a heavy duty 15hp motor that I need to try
[22:31:51] <JT-Shop> 40 is a bit much I think
[22:32:08] <CHNCguy> Well did u put an a/c reactor on the line side?
[22:32:47] <zeeshan|2> why put an ac reactor
[22:32:47] <zeeshan|2> ;D
[22:33:06] <CHNCguy> Are u trying to start the RPC with the drive directly connected? Or are u switching the drive with a relay?
[22:33:13] <JT-Shop> how many caps do you have on your 20hp rpc?
[22:33:31] -!- zeeshan has quit [Ping timeout: 272 seconds]
[22:33:52] <JT-Shop> no, I start the rpc then throw the switch on the 308 then take a nap then turn the drives on
[22:34:15] <JT-Shop> I can get 3k without tripping out now with my 10hp rpc
[22:34:22] <CHNCguy> I have 6 running caps, and 4 starting caps
[22:34:26] <JT-Shop> well 3k with rapids and such
[22:35:13] <CHNCguy> zeeshan, an ac reactor just helps the electronics down the line for inrush current and voltage fluctuations
[22:35:20] <JT-Shop> I have mostly 60mf caps and IIRC 4 on AC 2 on BC and 2 on AB with C the generated phase
[22:36:41] <rob_h> JT has a nice 50amp PM servo/Spindle motor to spin up 0 - 6k pritty fast.. so quite nice inrush demand there plus the axis moving around
[22:36:59] <CHNCguy> Ill have to look at the specs, I use L2 for the 3rd phase and bridge L1 to L2 to start
[22:37:33] <PetefromTn> Okay guy ran the program again and ran into another little problem. Wanted your advice.
[22:37:58] <CHNCguy> Well my rule is, if spindle is 7.5hp, and drives are 2kw or more than a 20hp rpc is needed to max out
[22:38:27] <PetefromTn> After the drilling operation the machine just brings the tool up to the safe Z level and stops and gives an M6 for the next tool. LinuxCNC asks you to change to that tool and hit okay.
[22:38:31] <CHNCguy> You can always add another idler motor
[22:38:44] <CHNCguy> I did this to power my 40hp mazak
[22:39:19] <CHNCguy> I had it run off a 40hp rpc and added a 20hp idler that I started after the 40hp, and then switched the mazak on
[22:39:23] <PetefromTn> Well this drill chuck is rather long and it stopped right above the workpiece so I was unable to remove it so I can change tools and LinuxCNC has no jog while paused feature so I could not raise the head to change tools.
[22:39:25] <rob_h> 11kw motor so 15hp
[22:40:22] <CHNCguy> I never like to go more than half the motors rated hp for draw, ive had issues in the past with phase fluctuations.
[22:40:56] <rob_h> yea i think the siemends drive can be picky on phases as it does regen back to line also
[22:41:11] <PetefromTn> I need to modify my post processor in camBam so I can have the machine go up to a toolchange height enough to get the current tool out and insert the next tool. What would you input there I assume machine coordinates Z height of appropriate position?
[22:41:22] <rob_h> PetefromTn, sorry cant help i dont use the next tool function sorry.. must suck no Atc
[22:41:47] <PetefromTn> Actually I have an ATC it is just not finished being retrofitted into the control.
[22:41:51] <rob_h> G91 G28 Z0 does that not send it back to the G28 for u, which is normaly set at the machine Z top/home
[22:41:59] <rob_h> manual tells you how to set the G28
[22:42:03] <rob_h> g28.1 i think?
[22:43:25] <PetefromTn> Okay so I can input that into the PP for toolchange after the M6 command and I should be good once I setup the machine G28?
[22:43:34] <JT-Shop> I need to up my wire size and try the 15hp to see what I get
[22:43:57] <rob_h> before the tool call
[22:44:02] -!- chillly has quit [Quit: Leaving]
[22:44:23] <JT-Shop> CHNCguy, what do you mean by this?
[22:44:23] <JT-Shop> <CHNCguy> I never like to go more than half the motors rated hp for draw, ive had issues in the past with phase fluctuations.
[22:44:24] <rob_h> so end of drill, G80 G00 Z to clear.. then G91 G28 Z0 , then Txx M6
[22:44:28] <PetefromTn> This of course would be temporary until I can get the toolchanger finished. I need to make some parts here and it will be a little while before I can get it working.
[22:45:17] <PetefromTn> No I am trying to setup the Post Processor to bring the machine to the top of Z after each toolchange.
[22:45:40] <rob_h> normaly nice to have G28 on Z to tool change hight anyway. so just put them 3 words in, Z moves up stops spindle also.. and there ready for the T command
[22:46:10] <PetefromTn> I think you are right tho If I input the G91 G28 then the next line is M6
[22:47:36] <PetefromTn> The code CamBam is putting out looks good so far but ya gotta get the tool out of the work to change the cat40 tooling here LOL
[22:47:42] <rob_h> G91 G28 on its own will send all Axis to G28 point
[22:48:01] <CHNCguy> JT-shop, I mean that our CHNC's have a max spindle rating of 7.5kw which equates to about 7.5hp, This does not include all of the peripheral electronics running off the RPC. Each Drive probably sucks 1kw when driven hard. What about your relays? Spindle drive it self, etc. etc.
[22:48:06] <PetefromTn> Does the G91 G28 also turn off the spindle automatically?
[22:48:17] <rob_h> no
[22:48:30] <rob_h> just put a m05 on the end ;)
[22:48:34] <CHNCguy> When your motor gets pushed over half its HP, it starts to suck on the fake phase and then throw all ur phases out of sync
[22:48:39] <rob_h> then turn it off while it goes up for u
[22:48:56] <rob_h> chncguy this is a diff machine not a CHNC
[22:49:06] <CHNCguy> Ohh... My bad ;)
[22:49:15] <CHNCguy> But still
[22:49:18] <PetefromTn> interesting the code I just posted does not have any M5 in it and the spinde stopped for the toolchange anyways...
[22:49:18] <rob_h> so 11kw 15hp spindle motor... plus axis
[22:49:39] <rob_h> i think the linuxcnc tool change thingie prob does it, would be bad other wise ;)
[22:49:54] <CHNCguy> So what is being asked again? LOL
[22:49:55] <rob_h> i dont know what it does and does not do sorry
[22:50:16] <rob_h> jt has a machine, 11kw spindle motor... prob 1kw each servo 3axis..

[22:50:37] <PetefromTn> G80
[22:50:38] <CHNCguy> But if you are running a RPC you have to have 2x the idler motor to run effectively and nicely...So for a 15hp motor you would want a 40hp
[22:50:39] <PetefromTn> m9
[22:50:44] <PetefromTn> This is the code for the first op and I watched it stop the spindle after this for the toolchange.
[22:50:47] <rob_h> lol, PetefromTn try pastbin ;)
[22:50:56] <CHNCguy> LOL
[22:50:58] <PetefromTn> oh okay sorry..
[22:51:11] <PetefromTn> I am not that great with this IRC stuff yet LOL
[22:51:28] <CHNCguy> If you have a 15hp spindle motor. Assuming All of you electronics are on 120v different line than your RPC you could do ok with a 30hp
[22:51:31] <JT-Shop> CHNCguy, yea my CHNC runs perfect

[22:52:25] <JT-Shop> the 308 is a small VMC with 7.5 hp spindle
[22:52:28] <CHNCguy> The issue is that the spindle is a 15hp spindle, but the draw will cripple your 3rd phase

[22:56:27] <MrSunshine> found the ones for power sweapers or whatever but it costs 5x the price of the strips in shipping :/
[22:56:32] <rob_h> so just need to issue next move in this case

[22:56:46] <CaptHindsight> paging tjtr33, was wondering what is a good small EDM for aluminum parts say < 6"x6"x6"
[22:57:02] <rob_h> no G43 ether? or was that some where else
[22:57:16] <CHNCguy> If you have a multimeter you should see 120/G 120/G 240/G (240 is your high leg). G= Ground
[22:57:42] <CHNCguy> You should have only 1 high leg and that should goto your middle tap on your transformer.

[22:59:11] <CHNCguy> Either way, sounds like a great project, got any pics JT?
[22:59:49] <JT-Shop> I don't think I've tried putting the generated leg on the middle tap, what's the reason for that?
[23:00:12] <JT-Shop> http://www.gnipsel.com/shop/machine-shop.xhtml
[23:00:54] <PetefromTn> Not really sure man.
[23:01:08] <CHNCguy> Well I don't really know...but I could not get my Haas powered properly, so I called Haas and they said that when using an RPC the high leg must always be on the middle leg. Electrician rule. Because lots of the sensing and peripheral electronics allow voltage fluctuations on the middle leg of transformers, but not on the others...
[23:01:27] <rob_h> PetefromTn, http://pastebin.com/tHF4jazD this is modded up for u
[23:01:32] <rob_h> how id write it hope it helps,
[23:01:32] <JT-Shop> thanks for the tip
[23:01:33] <PetefromTn> I just need to know where to put the G91 G28 in the post so it will go to some height I designate. Right now it goes to the clearance plain.
[23:01:51] <rob_h> i put in a G54 also so uses work offset G54 , uses H02 from tool table so need to measure the tool

[23:03:59] <CHNCguy> JT, try to get your high leg on your center tap meaning L2 and let me know ;)
[23:05:48] <JT-Shop> ok
[23:05:51] <rob_h> PetefromTn, btw, on line 5 might want to make Z bigger value to clear any parts i dont know if it flat or what
[23:06:14] <rob_h> waits for the US to be plunged into darknes by JT ;)
[23:06:34] <CHNCguy> When you run a rpc that fake leg that u generate is higher than the other 2 when measured across eachother
[23:07:20] <PetefromTn> OK
[23:07:23] <CHNCguy> This is what u should see with a DMM/Multimeter L1-L2 260+ L1-L3 240- L2-L3 260+

[23:17:55] <JT-Shop> no change in symptoms, still trips out at 4k
[23:18:05] <JT-Shop> I really think I need more hp on my rpc
[23:18:34] <CHNCguy> yup now u know its ur rpc
[23:18:42] <CHNCguy> just add an idler
[23:18:46] <CHNCguy> like a 5hp
[23:19:15] <CHNCguy> Hook it up with a switch and switch it on after ur 15p turns on fully
[23:19:23] <CHNCguy> run it parallel
[23:19:34] <CHNCguy> not series
[23:19:37] <andypugh> Ot go solid-state....
[23:19:58] <CHNCguy> 20hp solid state = 2k+
[23:20:10] <andypugh> Only if you _buy_ it
[23:20:31] <CHNCguy> lol
[23:20:41] <CHNCguy> got schematics to _make_it?
[23:20:55] <JT-Shop> right now I'm running on a 10hp
[23:21:01] <andypugh> I was thinking more along the lines of stealing :-)
[23:21:06] <CHNCguy> lol
[23:22:14] <andypugh> Though, actually, I reckon a fmesa card, 3-phase PWm and some big power transistors and caps might do the trick.
[23:22:16] <JT-Shop> right now with the work rob_h and I did the other day it runs 10 times better than it had in a while
[23:22:33] * JT-Shop waits for the schematic
[23:24:08] <JT-Shop> wow propane is $4 a gallon more than double
[23:25:32] <CHNCguy> dang, gasifier here I come
[23:26:20] <CHNCguy> Do you have a spare 3 phase motor laying around?
[23:27:01] <JT-Shop> a few
[23:28:05] <Jymmm> If you connect three 3h motors together, do they become one phase with the universe?
[23:28:14] <Jymmm> 3ph*
[23:28:49] <CHNCguy> wire the 3 leads to the same leads on your rpc box and see what happens, you will have a slower start time, but when they are up and running then try ur mill
[23:29:28] <JT-Shop> I have several 3ph machines on the same buss, a 7.5hp lathe, a surface grinder
[23:29:43] <JT-Shop> the CHNC is on it's own rpc
[23:29:50] <CHNCguy> lol what u could do.......
[23:29:58] -!- wboykinm has quit [Remote host closed the connection]
[23:30:01] <CHNCguy> run ur lathe on the slowest setting
[23:30:09] <CHNCguy> and then try ur mill also,
[23:30:14] <JT-Shop> I tried running the lathe spindle before with no improvement
[23:30:15] <CHNCguy> but lathe has to be little or no load
[23:30:28] <CHNCguy> with no load?
[23:30:37] <JT-Shop> run the spindle out of gear
[23:30:57] <JT-Shop> it was in gear before spinning the spindle and 4 jaw
[23:32:04] <CHNCguy> run with no load
[23:32:38] <CHNCguy> if it has any load at all if will not help
[23:32:55] <CHNCguy> it
[23:34:03] -!- lyzidiamond has quit [Client Quit]
[23:34:14] <CHNCguy> work better?
[23:38:37] <JT-Shop> yes it does help and I hear the lathe motor buzz during spindle spool up
[23:38:48] <JT-Shop> I'm running 4500 on the spindle with rapids
[23:39:07] <JT-Shop> actually I have both the lathe and surface grinder on
[23:39:57] <CHNCguy> Glad that helped, can u max the spindle?

[23:40:42] -!- spatialbrew has quit [Remote host closed the connection]
[23:41:36] <CHNCguy> you need a 20hp RPC to be happy, the start caps are no big deal, just get large ones to start the rpc under 1 sec, the running caps help to smooth the 3rd phase I cant remember the rating, I can look tho
[23:41:40] <JT-Shop> not tried yet, program running
[23:41:58] <JT-Shop> any info is helpful
[23:42:28] <CHNCguy> You helped me aton, its only fair that i try to return the favor ;), but you could get a 40 hp and run all ur machines at one if need be
[23:43:00] <CHNCguy> I once*
[23:43:01] <CHNCguy> once*
[23:44:21] <JT-Shop> I usually only run one, and the CHNC has a built in rpc the rest of the fleet is single phase
[23:44:48] <JT-Shop> I need to find a 20hp motor
[23:45:06] <CHNCguy> what hp is ur lathe 3ph motor?
[23:45:14] <JT-Shop> and swap the 8-4 SO for some 6-4 SO
[23:45:21] <JT-Shop> 7.5 I think
[23:45:31] <JT-Shop> been a while since I looked
[23:45:50] <CHNCguy> well 1 large motor is better than 2 small ones, you need to find an induction a/c motor, that what mine are

[23:47:03] <JT-Shop> like a normal ac motor?
[23:47:04] <CHNCguy> ohh
[23:47:07] <CHNCguy> the spindle :)
[23:47:11] <JT-Shop> here goes 5.5k
[23:47:20] <JT-Shop> did 5.5k
[23:47:22] <CHNCguy> try it 5.5k :)
[23:47:41] <CHNCguy> 6k?
[23:47:43] <JT-Shop> it ain't never did that since I had it
[23:47:52] <CHNCguy> sweet! :D
[23:48:18] <JT-Shop> yes, thanks for the help
[23:48:55] <CHNCguy> Whoot Whoot, im glad you know what you need now! Im gonna have tons of questions for you in a week or so as I start to wire up my lathes ;)
[23:49:54] <JT-Shop> I hope I remember the answers
[23:50:42] <CHNCguy> Haha, I can't thank you enough for the help from ur site, where are ya located by the way?
