[00:05:36] <JT-Shop> time to call it a day here
[00:06:05] <Tom_itx> yup
[00:08:43] <FinboySlick> Now fore the really challenging part... Finding documentation about my drivers characteristics ;)
[00:17:16] <SWPadnos> ssi, I may have misunderstood what you said earlier - are you writing G-code?
[00:17:36] <SWPadnos> (I assumed you were writing some module in C or something)
[00:18:00] <SWPadnos> if so, pressing ESC should stop preview generation (assuming you're using AXIS)
[00:18:26] <SWPadnos> there are also special commands you can put in comments in the code to turn preview generation on and off
[00:19:17] <SWPadnos> I don't remember exactly what they are, but you should be able to find them - they're something simple like (AXIS, on) and (AXIS, off) (or preview_on/preview_off ...)

[01:31:16] <Tom_itx> i'm looking at my 7i43-big.ini file settings for max_velocity=10 and max_acceleration=20 and in hal configuraton looking at the stepgen00 settings i see maxaccel=200 and maxvel=200. i tried renaming the variables in the ini file to match and still no change. where are the values loaded from? am i looking in the wrong file?
[01:36:28] <Tom_itx> err, i read the wrong values, the values in hal configuration were both 0
[01:36:34] <Tom_itx> not 200
[01:36:55] <Tom_itx> and it didn't change when i renamed the variables in the ini file
[01:37:55] <Tom_itx> from MAX_VELOCITY to MAXVEL and MAX_ACCELERATION to MAXACCEL which is what they show as in hal config

[03:23:36] <l0st1nsp4c3> hey guys quick question what's your opensource CAD/CAM solution to create your cad and then turn it into gcode?
[03:24:45] <jdhNC> the quick answer would be heeks
[03:28:18] <l0st1nsp4c3> ok
[03:28:54] <elmo401> http://code.google.com/p/heekscnc/
[03:39:02] <l0st1nsp4c3> thxs guys
[03:39:09] <l0st1nsp4c3> had looked at it before but wasn't 2 sure
[03:39:19] <l0st1nsp4c3> and lazycam = $$$ for something that didn't seem worth it for me
[03:39:20] <elmo401> it works rather well
[03:39:34] <elmo401> sad to hear it
[03:40:12] <l0st1nsp4c3> hear what?

[03:52:05] <l0st1nsp4c3> i didn't spend any money on lazycam
[03:52:22] <l0st1nsp4c3> I tried the version that gives you 50lines of gcode fiddled with it and it's nice for text and what not
[03:52:39] <l0st1nsp4c3> but it is what it's name says...a lazy....sorta cam software
[03:52:55] <l0st1nsp4c3> and after messing around with it
[03:53:09] <l0st1nsp4c3> I didn't wanna spend money on it per say....it's that or get it full blown with Mach3
[03:53:43] <l0st1nsp4c3> but I really Like EMC and been a slackware user for over 14years makes me wanna stick to linux based stuff
[03:54:03] <l0st1nsp4c3> actually 15years now...damn time passing by lol

[04:07:01] <jdhNC> heh, yep, you did.
[04:07:43] <jdhNC> After reviewing your order, I have found that the G0704 Mill/Drill is expected to arrive in our warehouse on approximately July 1, 2011.
[04:08:28] <jdhNC> and the new expected shipping date is May 20, 2011.
[04:08:43] <jdhNC> We still expect to receive one for you on April 29.
[04:09:10] <jdhNC> The expected date of arrival of February 14, 2011
[04:14:50] <l0st1nsp4c3> gotta read how to change fonts in heekscnc lol

[11:45:47] <alex_joni> pingufan: http://www.linuxcnc.org/docview/2.4/
[11:46:00] <alex_joni> getting started, users and integrator manual
[11:47:06] <archivist> lots to read, there are many grades of novice to EMC2 it would be hard to create docs specially for them
[11:47:19] -!- Techrat has quit [Ping timeout: 250 seconds]
[11:47:31] <pingufan> Thank you. Can I compare EMC2 with MACH3 ? I found a really good book in the Internet: machining.pdf
[11:48:13] <pingufan> Actually I must find a way to learn G-Code programming without damaging a tool with every try. ;)
[11:48:24] <Valen> anything mach can do emc can do better
[11:48:31] <Valen> pingufan: MDF
[11:48:41] <archivist> mach3 is commercial and closed source
[11:48:43] <Valen> machine MDF its softer than your tools ;-P
[11:48:51] <pingufan> Ok.
[11:49:22] <pingufan> So I can presume that everything that MACH can do (and is described/explained) will work with EMC2?
[11:49:38] -!- e-jones has quit [Read error: Connection reset by peer]
[11:49:51] * nullie machines foam, heh
[11:50:03] <Valen> we have lots of foam
[11:50:38] <pingufan> Sure, I will also start with "Styrodur", a pink colored foam....
[11:50:39] <Valen> bah
[11:50:46] <Valen> we have lots of mdf, not much foam
[11:51:06] <archivist> I machine air its cheaper
[11:51:08] <Valen> also mdf is somewhat stronger ;->
[11:51:13] <pingufan> How many program loops can be nested in EMC2?
[11:51:20] <Valen> won't tell you if you gouge though archivist
[11:51:43] <archivist> air has a brain watching!
[11:53:19] <pingufan> I want to mill down a plastic enclosure from 15mm -> 5mm. So I must repeat in multiple layers a sequence of moves. As the area has to be milled down, I have to move in zig-zag across it. So This are actually three nested loops.
[11:53:27] <pingufan> Does EMC allow that?
[11:53:38] <Valen> if your eye can see it its a horrible gouge ;-P
[11:54:26] <archivist> pingufan, sure
[11:55:16] -!- e-jones [e-jones!~jkastner@nat/redhat/x-kpkwwdsrtszuonur] has joined #emc
[11:55:44] <pingufan> Is all that described in tutorial style in the emc docs?
[11:57:43] <pingufan> archivist: ?
[11:57:44] <archivist> machining tends to far too varied for tutorial style writing
[11:58:08] <Userli> I would like to display the % of lines executed. Can I access the value of current_line in emctop from within a component?
[11:58:17] <pingufan> I need some first "guide" to learn the basics
[11:59:12] <archivist> which basics....there are many, have a read of the docs and ask questions
[12:01:58] <pingufan> Currently I got my mill doing first simple moves in rapid move and slow move, and I also was happy to mill a simple rectangle into a wooden plate. But now I want to do more complex things, like nested program subroutines.
[12:03:27] <pingufan> Such things should be explained so well that I can learn from that.
[12:03:38] <archivist> read the O code part of the user manual
[12:04:08] <pingufan> Thank you.

[12:49:07] <SWPadnos> skunkworks, doing a lot of work for one company, off site (which is why I'm not on IRC much)
[12:49:30] <SWPadnos> (to answer your question from last night :) )
[12:51:02] <skunkworks> SWPadnos: ah - well - keeps you out of trouble then ;)
[12:51:11] <SWPadnos> that's the theory
[12:51:33] <SWPadnos> though I did discover a couple of ways of getting into trouble - a friend of mine has a couple of lasers he offered to give me
[12:51:48] <skunkworks> heh - how much power?
[12:51:55] <SWPadnos> a 4kW HyperTherm CO2 laser, and a 1.5 kW YAG
[12:52:01] <SWPadnos> big :)
[12:52:08] <skunkworks> wow
[12:52:11] <SWPadnos> yeah
[12:52:23] <skunkworks> we only have a 1kw co2 laser here
[12:52:26] <skunkworks> (PRC)
[12:52:40] <SWPadnos> they wouldn't fit in my garage, so I'd have to rent some industrial space
[12:52:48] <SWPadnos> I didn't know you were in China :)
[12:53:07] <skunkworks> I was just going to ask if you where going to build a shop
[12:53:23] <skunkworks> heh - the brand of the laser is prc
[12:53:47] <SWPadnos> can't really build one on my property - there's no good access to the back yard (plus there's the wife factor)
[12:53:50] <skunkworks> I don't think it is the peoples republic of china - - but who knows.
[12:53:55] <SWPadnos> heh
[12:53:59] <skunkworks> heh
[12:54:13] <skunkworks> is there industrial space near you?
[12:54:20] <SWPadnos> turns out I know someone who works at HyperTherm - went to college with him
[12:54:30] <SWPadnos> (not the guy who offered me the lasers)
[12:54:37] <SWPadnos> yeah, about 4-5 miles
[12:55:16] <SWPadnos> maybe even closer. I should see if there's space in the IBM technology center - that's about a mile away

[14:15:42] <grommit> I am trying to tune servos on a gantry machine. I want to run a program that loops but when I try to it says "all joints must be homed before going into coordinated mode". I do not (yet) have home switches, but I selected each of the 4 joints and clicked "Home Axis" and I have the little home indication by each one. Why does it think it isn't homed?
[14:16:17] <jdhNC> does it think you have more axis than that?

[14:17:58] <jdhNC> do you have mulitiple motors for one axis?

[14:20:12] -!- Userli has quit [Quit: Ex-Chat]
[14:20:29] <jdhNC> my guess is one of your Y's isn't homed, but I have no idea why or how to fix it.
[14:20:50] <grommit> In my ini file I have AXES=8 and COORDINATES=X Y Z V
[14:21:03] <jdhNC> why 8?
[14:21:11] <grommit> In order to use "V"
[14:21:31] <SWPadnos> you used to have to tell EMC what the highest axis number was, more or less
[14:21:40] <SWPadnos> I don't know if that's still true
[14:22:03] <grommit> If I use "A" I get an annoying Angular Jog Speed slider in Axis that doesn't do anything. So I am using V (hence AXES=8) and the angular jog is gone
[14:22:26] <grommit> Yes, it is still true.
[14:23:07] <grommit> So do I need to somehow "home" the non-existent axes? Is that why Axis is telling me it isn't homed?
[14:23:27] <jdhNC> that is my guess, based on pretty much nothing :)
[14:23:40] <grommit> good guess ;-)
[14:24:10] <jdhNC> why isn't it X Y Y Z?
[14:24:16] <grommit> Any ides how one homes a non-existent axis? Guesses welcome...

[14:24:52] <grommit> I tried X Y Y Z but had a problem (can't remember what exactly) and was told to no use the same letter twice.
[14:27:49] <grommit> I just looked back in the mail list for what problem I had using X Y Y Z, and it was that if you use the same letter twice you only see one joint not both, and you can't home then either!
[14:29:22] <Tom_itx> x y z a
[14:29:53] <jdhNC> then TYPE = LINEAR for [AXIS_3] ?
[14:30:02] <grommit> yes, I have that.
[14:30:30] <Tom_itx> what is the 3rd axis?
[14:30:33] <SWPadnos> A is angular, as defined by the RS274NGC spec
[14:30:44] <Tom_itx> ya
[14:30:48] <grommit> Using V as 3rd axis
[14:30:51] <SWPadnos> regardless of whether you put LINEAR or ANGULAR in the ini file
[14:31:02] <grommit> yes, that was my experience.
[14:32:07] <grommit> I see all the joints. I can control each joint. I just can't (apparently) home ALL joints/axes....

[14:47:20] <grommit> What is HOME ALL?
[14:47:46] <grommit> I home each individual axis to no avail, where do I find HOME ALL?
[14:47:50] <SWPadnos> you can set up a homing sequence, and home all axes (or just the ones you choose) with one key
[14:48:14] <grommit> ah yes, I recall this from my mill config...I don't remember how though...
[14:48:56] <SWPadnos> look up the HOME_SEQUENCE ini setting

[15:16:15] <grommit> By the way, I did QUITE solve my problem. I am able to home joints 0,1,2 with Home All button but joint 3 (or V) doesn't. But I can use the Machine-Homing menu to home it individually and then can run MDI or programs
[15:16:21] <grommit> did=didn't
[15:17:01] <Tom_itx> i'm guessing here, but if you fix up your ini file it may start working
[15:17:21] <Tom_itx> HOME = 0 0 0 0 and maybe a few other parameters
[15:17:32] <grommit> Yes, I had a config much like that last one, but I don't want to use A axis because it wants to give me an angular jog slider in Axis for it.
[15:17:50] <Tom_itx> so call it V in the coordinates =
[15:17:51] <Tom_itx> section
[15:17:55] <grommit> Yes, I suspect you are right on the config....
[15:18:00] <grommit> I am calling it V

[15:40:05] <Tom_itx> y2 might get misinterpreted
[15:40:53] <grommit> I think that is just a tag and has no bearing on anything
[15:41:49] <Tom_itx> if so what causes G1 x1 to go to the axis_0 amp?
[15:42:10] <Tom_itx> or G1 Y2 to go to the axis_1 amp?

[17:48:44] <Connor> I've purchase qty 1 from a place.. . But, yea.. if you found another place.. I'll look. I was thinking of trying to put together a kit.. maybe
[17:48:47] <Tom_itx> he wanted to know how many you might want
[17:48:58] <Tom_itx> tens or thousands
[17:49:11] <Connor> probably tens.
[17:49:16] <Tom_itx> i told him you would commit to thousands
[17:49:23] <Connor> ROFL . :)
[17:49:54] <Tom_itx> so he is checking for me
[17:49:58] <Connor> ok
[17:50:08] <Connor> I have the exact model number now.
[17:50:13] <Tom_itx> he goes to those markets you showed me

[19:20:14] <anonimasu> FinboySlick: the ones with pivot have angular increase of the error
[19:20:27] <anonimasu> so if you measure away from zero you will have a larger error then actual...
[19:21:42] <anonimasu> but they are very useful.
[19:28:44] -!- robh__ has quit [Ping timeout: 276 seconds]
[19:30:47] <FinboySlick> JT-Shop: Yeah, I was refering to test indicators. I'm just unclear of the technical advantages of the pivot. I can understand that it would have less resistance than a slide mechanism but as anonimasu pointed out, that also means you have varying degree of error.
[19:31:47] <JT-Shop> you can adjust it easier as it is on a friction and you just move the tip as needed
[19:32:10] <JT-Shop> can't hardly get a dial indicator in a hole unless real big
[19:32:43] <FinboySlick> JT-Shop: Aaah... Now that makes a lot more sense to me.

[20:04:55] <mrsunshine_> hpopols, nop ..
[20:05:03] <mrsunshine_>
[20:05:26] <mrsunshine_> dont know about threading etc on it tho

[20:11:28] <syyl> not like the average chinese 9x20
[20:11:48] <mrsunshine_> aparently they were made about 70km from where i live =)
[20:13:47] <mrsunshine_> hopefully all gears etc still exist for it, as it seems the threading and stuff is gear controlled =)
[20:18:28] <FinboySlick> mrsunshine_: Get a bunch of servos and CNC it ;)
[20:19:09] <mrsunshine_> FinboySlick, dont know if i will, as a manual lathe is nice, and its an old piece =)
[20:19:20] <mrsunshine_> it will serve me well without computer control realy =)

[20:37:11] <andypugh> How to machien the end of a 25mm ballscrew on a lathe with a 20mm spindle bore...
[20:37:30] <andypugh> I think the answer is "borrow a bigger lathe"
[20:37:34] <syyl> find a bigger lathe
[20:37:49] <syyl> you can try it with a steady rest
[20:37:51] <Tom_itx> andypugh will it fit between centers?
[20:37:58] <Tom_itx> live center on one end
[20:38:31] <andypugh> I don't have a steady-rest, but I am considering just drilling a centre hole in it using a lathe at work.
[20:38:52] <syyl> thats, what i would do
[20:39:01] <syyl> throw it in the car, machine it at work :D
[20:39:06] <Tom_itx> i'd wrap it with something to protect the screw
[20:39:18] <andypugh> Don't have a car...
[20:39:20] <Tom_itx> thin brass stock or something
[20:39:30] <syyl> for machining?
[20:39:35] <syyl> soft jaws :)
[20:39:45] <Tom_itx> or that if you have them
[20:39:55] <FinboySlick> Brass ring around the screw, tripple-roller rest instead of a tailstock.
[20:40:04] <syyl> a friend of mine showed a neat trick
[20:40:12] <syyl> *searches the picture*
[20:40:43] <FinboySlick> That's more work than taking it at work though.
[20:40:48] <andypugh> I have access to a nice old Colchester Student, with a collet-style chuck, but it is 40 miles away, in the middle of London.
[20:43:00] <archivist> er, you work for a car company, borrow one

[20:44:58] <syyl> and chucked that up
[20:45:03] <andypugh> I am going to be using CBN tooling, and sparks will fly. I imagine the workshop dudes looking askance at that, and thinking I am incompetent.
[20:46:50] <skunkworks> andypugh: ! I have my uno now. One question - I assume all the resolvers need to be the same for the balancing to work?
[20:48:02] <andypugh> I am not sure. I think it ought to work best with identical ones, but still work with different ones.
[20:48:10] <archivist> syyl, its either that or machine up some soft jaws
[20:48:32] <syyl> yes :)
[20:48:52] <andypugh> I haven't bothered in the past. Ballscrews are very hard, and the working surfaces are protected by the non-working surfaces.
[20:52:44] <anonimasu> they machine pretty well
[20:52:53] <anonimasu> if you sacrifice a carbide bit to get under the case hardening
