[00:01:26] <andypugh> Some have power motor drivers etc
[00:04:58] <theorb> theorb is now known as theorbtwo
[01:11:08] <genehacker> so do I need to put resistors between my parallel port and stepper controller?
[01:15:50] <Jymmm> * Jymmm first laser engraving... http://i38.tinypic.com/1zvyafo.jpg
[01:17:50] <skunkworks> Jymmm: very neat. what are you using for hardware?
[01:18:17] <Jymmm> It's a ULS M-300
[01:18:18] <skunkworks> looks like rastering?
[01:18:28] <Jymmm> it is
[01:19:15] <skunkworks> does the software work well?
[01:20:54] <Jymmm> skunkworks: Ok, unlike CNC or cheap china lasers, etc. You use CorelDraw (primarily), or AutoCad or AI, to draw, and you just install a print driver. that's it. Once you print, it goes to the machine and you could disconnect the computer if you wanted to.
[01:21:34] <Jymmm> You can even place it on the network using a parallel print server
[01:21:49] <Jymmm> or a USB to parallel adapter
[01:21:58] <skunkworks> oh - so it pretty much acts as a printer. neat.
[01:22:21] <skunkworks> seems like a cool way to do it.
[01:23:48] <Jymmm> Yeahm exactly.
[01:25:23] <Jymmm> It has a serial port too, but why bother unless I want to laser from a uC =)
[01:27:48] <Jymmm> skunkworks: I'm still learning the thing. Actually just went thru and cleaned EVERYTHING on it. It has been in storage for 5+ years before I bought it.
[01:30:13] <skunkworks> nice - good find
[01:36:17] <Jymmm> thanks, I think so too. I still have to buy a bunch of very expensive add-ons, so we'll see
[01:36:38] <Jymmm> Like almost $4000 worth.
[01:36:57] <skunkworks> what are your plans for it>
[01:36:58] <skunkworks> ?
[01:38:02] <Jymmm> Mostly cutting, which requres a cutting table, air assist kit, and ventilation system.
[01:39:03] <Jymmm> ULS is THE most expensive laser you can buy.
[01:39:52] <Jymmm> I WAY underestimated the "replacement" parts pricing. What I thought might be $300 is really $1200
[01:40:14] <Jymmm> But If I can find used, hawt damn =)
[01:42:01] <skunkworks> heh
[01:46:21] <Jymmm> I mean come on.... $1300 for a cone, some tubing, pressure regulator, water trap, and pressure gauge?!
[01:46:36] <Jymmm> we're talking 50PSI MAX
[01:46:58] <genehacker> it must not be regular tubing, it must be QUALITY tubing
[01:47:21] <Jymmm> genehacker: Like the lets move the decimal point quality, huh?
[01:48:33] <genehacker> whoa that's pretty expensive
[01:48:48] <genehacker> even more expensive than national instruments stuff
[01:48:56] <Jymmm> exactly
[01:49:22] <Jymmm> I am surprised they only charge $20 for each gas spring
[01:50:03] <genehacker> I'm substituting an $80 cable with stuff I just have around
[01:50:41] <Jymmm> $20 for this... http://www.guden.com/ItemDisplay/displayItem-GGS43-020-K.aspx
[01:50:49] <Jymmm> I need two of them
[01:51:25] <Jymmm> Or, I save the $40 and keep using the stick I have. Which is a PITA
[02:31:55] <elmo40> get one from a trunk lid off a car :P
[02:47:26] <Jymmm> elmo40: Uh, a tad too big =)
[03:53:04] <Mendellook> Mendellook is now known as Mendel|snore
[05:32:41] <L84Supper2> Red Zone 3300-4500 RPM http://cgi.ebay.com/Alliant-Model-RT-2-3HP-42-inch-Vari-Speed-knee-mill-/320570943565?pt=BI_Mills
[05:32:56] <L84Supper2> no tooling :(
[08:26:21] <Fox_M|afk> Fox_M|afk is now known as Fox_Muldr
[08:40:41] <Fox_Muldr> Fox_Muldr is now known as Fox_M|afk
[09:03:12] <IchGuckLive> good morning from Germany
[10:27:59] <maximilian_h> placing windows with tkinter is making my mind hurt, is pygtk any better ? Or even glade with python.
[10:28:32] <maximilian_h> Or qt with python, at least I know my way with qt
[10:57:16] <Guest645> hello ?
[10:59:25] <jthornton> hi
[11:29:46] <alex_joni> hi ?
[12:03:20] <maximilian_h> hi ? :)
[14:35:18] <elmo40> if I have a PWM board that uses a manual trim pot to control the RPM would I be able to replace it with a digital-to-analog circuit to have EMC control the speed?
[14:47:44] <skunkworks> maybe.. I know people have done pwm -> Priniter port -> opto -> RC circuit -> hooked into where the pot was.
[14:48:51] <skunkworks> here we go http://timeguy.com/cradek/cnc/lathe
[15:54:02] <mrsun> hmm, a gcode visualizer shouldnt be to hard to write should it =)
[15:54:17] <mrsun> and like opencamlib use quadtree for simulations :P
[15:56:21] <tom3p> is this enough for you? visualize gcode with AXIS, run a sim config and load your code
[15:56:57] <Jymmm> tom3p: That's WAY TOO EASY =)
[15:57:13] <mrsun> tom3p, wrong os for axis :P
[15:57:29] <Jymmm> mrsun: then boot a livecd
[15:57:37] <Jymmm> or a VM
[15:58:21] <mrsun> well i see it as i get a chance to learn some gcode and how it works together at the same time =)
[15:58:59] <Jymmm> mrsun: And if you dont have the right OS, then why did you ask me to make you some gcode for then?
[15:59:26] <mrsun> Jymmm, that was cause i didnt have a v-grooving software =)
[15:59:52] <mrsun> and i have linux on this one so no problem visualizing but i want to have a visualizer in haiku =) (www.haiku-os.org)
[15:59:53] <Jymmm> You wouldn't need it if you didn't have EMC
[16:25:43] <JT-Work> how does keystick.cc create the window you see when you run it?
[16:26:16] <Jymmm> Say that again
[16:26:33] <Jymmm> It's just a terminal app
[16:27:11] <JT-Work> so the terminal looks formatted some how
[16:27:27] <Jymmm> You mean the ascii art?
[16:27:36] <Jymmm> nice lil border, etc
[16:27:38] <JT-Work> is that what it is?
[16:28:13] <JT-Work> had me fooled
[16:28:59] <Jymmm> you mena like this...
[16:29:08] <Jymmm> +---------+
[16:29:08] <Jymmm> | |
[16:29:08] <Jymmm> | Jymmm |
[16:29:09] <Jymmm> | |
[16:29:11] <Jymmm> +---------+
[16:29:49] <Jymmm> There are some higher ascii chars that do single and double lined borders too
[16:29:51] <JT-Work> yea
[16:30:30] <Jymmm> Yeah, that's just ascii text actually: hyphen, plus, and pipe symbol
[16:31:55] <JT-Work> ok keystick.cc is making some sense to me know
[16:31:57] <JT-Work> now
[16:32:01] <Jymmm> =)
[16:33:42] <Jymmm> JT-Work: I liked keystick if you run emc GUI-less on one box, then the GUI on another box but still have control on the main box.
[16:35:39] <JT-Work> Jymmm: I was just studying keystick to see how it worked with EMC
[16:35:50] <Jymmm> gotcha
[16:36:09] <JT-Work> start with something simple
[16:36:12] <Jymmm> it was kludgy when I tried it, but that was long ago too
[17:09:36] <JT-Work> To call a global function "foo" is a shooting offense. :)
[17:15:00] <elmo40> skunkworks: that is a wee lathe ;)
[17:15:11] <elmo40> and very 'loose' electronics wiring
[17:16:23] <motioncontrol> good evening.excuse i have a question about g33.1 command.i have start a m4 s100 and my anaolg spindle run at 100 g/m in m4, after start g33.1 z-200 k10 and the analog out is 0 volt because.MY spindle at 0 volt have derive and rotation very slow, when the emc read the marker the encoder g33.1 start ok.Because g33.1 when read at interpreter setp analog out at 0 ?
[17:16:59] <ichudov__> Guys, is there a INCLUDE directory ina .ngc G-code file to include library finctions?
[17:17:08] <ichudov__> Needs answer ASAP boarding plane
[17:18:35] <ichudov__> I have started to write G code O<subname> sub' subs, and that is why I am asking
[17:18:48] <ichudov__> I will of course GPL all the subs
[17:19:11] <ichudov__> What I mean is something like !!!INCLUDE "mysubs.ngc" directory
[17:20:43] <skunkworks> elmo40: whatever works :)
[17:20:53] <cpresser> ichudov__if i recall it right, there is a 'o-code'
[17:21:03] <elmo40> skunkworks: ya, for now.
[17:21:11] <cpresser> http://www.linuxcnc.org/docview/html//gcode_main.html#r3_7
[17:21:31] <ichudov__> Awesome guys, you saved me in last minute, have a great day
[17:21:43] <elmo40> a good looking setup is all about form and function. plus, easier to troubleshoot the wires ;)
[17:22:19] <elmo40> how much was the spindle encoder?
[17:22:38] <skunkworks> that is cradeks lathe.
[17:22:48] <JT-Work> ichudov__: http://www.linuxcnc.org/component/option,com_kunena/Itemid,20/func,showcat/catid,40/lang,english/
[17:22:49] <elmo40> ah yes... timeguy.com ;)
[17:24:43] <ichudov__> in subs, are variables like #<x> locally scoped
[17:26:20] <JT-Work> http://www.linuxcnc.org/docview/html//gcode_main.html#cha:O-Codes
[17:26:23] <motioncontrol> good evening.excuse i have a question about g33.1 command.i have start a m4 s100 and my anaolg spindle run at 100 g/m in m4, after start g33.1 z-200 k10 and the analog out is 0 volt because.MY spindle at 0 volt have derive and rotation very slow, when the emc read the marker the encoder g33.1 start ok.Because g33.1 when read at interpreter setp analog out at 0 ?
[17:26:38] <motioncontrol> please help me
[17:30:34] <elmo40> if I read this correctly... seems like it is too low? therefore 0V ?
[17:32:56] <motioncontrol> elmo40, in mdi i start spindle m4 s100 and have 0.9 volt in analog out.when after run g33.1 z-200 k10 the analog is 0 volt. normaly the spindle is stop and if nor rotatyon can't read the marker on encoder. i thing it a bug
[17:33:08] <motioncontrol> i use 2.4.3
[17:34:38] <motioncontrol> when start the g33.1 the analog is 0 , the spindle is stop.if i rotatyon manually the spindle and read the encoder marcher the g33.1 sequenze is start
[17:34:54] <elmo40> if Z is moving too slow it won't be able to synchronize properly
[17:35:10] <elmo40> did you give a feed rate for Z ?
[17:35:26] <IchGuckLive> Hi from Germany
[17:35:30] <skunkworks> so - the second you type in g33.1 z-200 k10 the spindle stops?
[17:35:35] <elmo40> just paste your code online
[17:35:46] <elmo40> IchGuckLive: how is the oil well?
[17:36:04] <IchGuckLive> elmo40: fix and foxy
[17:36:24] <IchGuckLive> i finaly managet to overcam my arc problem
[17:36:26] <IchGuckLive> http://paste.pocoo.org/show/248066/
[17:36:28] <motioncontrol> skunkworks, yes the spindle is stop when i command g33.1 z-200 k10
[17:36:44] <IchGuckLive> so this is Eyal to G13
[17:37:11] <IchGuckLive> Equal
[17:37:30] <elmo40> if I change that to g20 I can actually use it ;)
[17:37:45] <elmo40> that entire script is equal to G13?
[17:38:04] <IchGuckLive> no no D inside
[17:38:39] <motioncontrol> skunkworks, have some idea because this problem.the analog is ok, because m3 or m4 fuction ok
[17:39:17] <skunkworks> motioncontrol: does it work if you put those 2 lines in a .ngc file?
[17:40:52] <motioncontrol> skunkworks, i don,t have prove it in auto, but i thing normaly in mdi is = at auto mode.
[17:41:44] <elmo40> in mdi mode when you type M3 S3400, it will 'know' that the spindle is on when you type the next line? I don't think so.
[17:41:53] <elmo40> motioncontrol: you need to have that in a program
[17:41:58] <elmo40> can't one-line it
[17:42:11] <elmo40> or, have it all on the same line!
[17:42:13] <motioncontrol> skunkworks, i remember this problem not are on 2.2.8 version
[17:42:33] <elmo40> m03 s100 g33.1 z-200 k10
[17:42:56] <motioncontrol> elmo40, i don,t prove it in a program in auto mode , but thing the mdi is = at auto
[17:43:07] <elmo40> mdi != auto
[17:43:11] <elmo40> it is manual input
[17:43:42] <motioncontrol> yes but all command in auto fuction in mdi normally
[17:43:58] <elmo40> I never have seen that
[17:44:04] <elmo40> just make a program
[17:44:08] <elmo40> why not?
[17:44:11] <elmo40> why always mdi?
[17:44:34] <JT-Work> motioncontrol: most do function normally
[17:44:40] <elmo40> mdi is for simple things... homing out, tool orientation, change tool, probing... not running a part.
[17:45:59] <motioncontrol> elmo40, mdi is semiautomatic and can resolve single line the partprogram
[17:46:18] <motioncontrol> JT-Work, at you fuction ok ?
[17:47:23] <JT-Work> que?
[17:49:14] <IchGuckLive> for the wiki do i have to "<href" a link to a uploadet file or is this going auto ?
[17:49:57] <JT-Work> you use the upload button at the bottom of the page
[17:50:23] <IchGuckLive> i used the top
[17:50:33] <IchGuckLive> but in fresh window
[17:51:05] <IchGuckLive> and then put the "upload:circular_spiral_pocket_subroutine.ngc" on the page
[17:51:15] <IchGuckLive> this wars wrong !?
[17:51:45] <JT-Work> should be right
[17:51:51] <motioncontrol> JT-Work, you thing the problem is only in mdi ?
[17:52:14] <JT-Work> could be, but I don't know for sure
[17:52:17] <IchGuckLive> JT-Work: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?G12-13
[17:52:26] <IchGuckLive> there is no link
[17:54:36] <JT-Work> did you upload the file?
[17:54:50] <IchGuckLive> yes i do it again
[17:55:12] <JT-Work> wait
[17:56:10] <IchGuckLive> Toolofst someone with the right spelling ?
[17:56:29] <IchGuckLive> 2F ?
[17:56:51] <IchGuckLive> Toolofset
[17:57:29] <JT-Work> you have the whole thing surrounded with <pre> so no links will be between those tages
[17:57:33] <JT-Work> tags
[17:57:45] <IchGuckLive> ok
[17:58:34] <IchGuckLive> yes worked
[17:58:52] <JT-Work> you can still use pre but put the link outside of them
[18:00:03] <JT-Work> <pre>
[18:00:05] <JT-Work> ...
[18:00:07] <JT-Work> </pre>
[18:00:08] <JT-Work> my link
[18:00:10] <JT-Work> <pre>
[18:00:11] <JT-Work> ...
[18:00:13] <JT-Work> </pre>
[18:00:30] <IchGuckLive> yes i now im used to work with HTML but not with wiki
[18:00:42] <JT-Work> yea, it is a bit different
[18:01:20] <JT-Work> http://www.usemod.com/cgi-bin/wiki.pl?TextFormattingRules
[18:02:00] <JT-Work> see #7
[18:03:30] <IchGuckLive> Perfect
[18:04:10] <IchGuckLive> so now on with G150 Rectangulas Equal to Haas
[18:14:46] <IchGuckLive> JT-Work: where is the page of g12-G13 located from the EMC nolage base so i can put G150 also there
[18:15:59] <IchGuckLive> i can not find it there
[18:16:30] <JT-Work> I don't understand your question
[18:18:05] <IchGuckLive> there is a side named G12/G13 and there is a Page index ! also the First button EmcKnowledgeBase
[18:18:20] <IchGuckLive> Page index is not edible!
[18:18:51] <JT-Work> yes it is at the bottom
[18:18:52] <IchGuckLive> EmcKnowledgeBase is edidable ,but there i can not find a Underfolder with G12/13
[18:19:10] <JT-Work> the page link?
[18:19:48] <JT-Work> [[G12-13]]
[18:20:14] <IchGuckLive> No coudt you please ad a new Page Named "G150 Rectangulare Pocket milling" for me Please
[18:20:36] <JT-Work> I can't right now I have to run to the other shop
[18:20:53] <IchGuckLive> ok this has time
[18:21:11] <IchGuckLive> i will now include this into the main Pocket.py
[18:21:29] <IchGuckLive> http://www.pictureupload.de/originals/pictures/020810201332_pocket_v1_c.png
[18:22:23] <IchGuckLive> if this is workeble i will put this then into Simple generaters
[18:48:41] <IchGuckLive> By till tomorrow
[20:38:49] <alex_chally> should I buy 2gb of ram for an intel atom runnig emc?
[20:39:08] <alex_chally> I don't really care one way or another, but it is $20 bucks I can spend elsewhere if it is really unncesseary
[20:39:30] <cradek> 1GB is plenty
[20:40:00] <cradek> I think all my EMC machines have between 512MB and 1GB
[20:40:41] <alex_chally> cradek, k, that is what I thought
[20:40:42] <alex_chally> not like I can
[20:40:47] <alex_chally> I can't get more if I have problems
[20:41:04] <alex_joni> a couple years ago we were forced to limit memory to 1GB
[20:41:09] <alex_joni> because of a RTAI bug
[20:46:29] <Fox_M|afk> Fox_M|afk is now known as Fox_Muldr
[20:50:45] <frallzor> yo
[20:52:14] <DaViruz> howdy
[20:52:37] <frallzor> its mistel Viluz
[21:02:51] <JT-Work> has anyone used one of those balanced fly cutters that use carbide inserts?
[21:03:25] <JT-Work> http://www1.mscdirect.com/CGI/NNPDFF?PMPAGE=1184&PARTPG=N2DRVSH&PMT4NO=91348289&PMITEM=97588925&PMCTLG=54&PMT4TP=*LTIP
[21:03:39] <Jymmm> JT-Work: One of these? http://www.google.com/products/catalog?q=craftsman+circle+cutter&cid=6126223025012671411&ei=Hm1gTMidPJ2oigSerszkAw&sa=title&ved=0CAcQ8wIwADgA#p
[21:03:53] <JT-Work> no
[21:04:03] <Jymmm> then nope =)
[21:06:58] <Mendel|snore> Mendel|snore is now known as Mendel|beer
[21:08:27] <skunkworks> that isn't a fly cutter - it is a T handle
[21:09:01] <JT-Work> with a tooth on it :)
[21:09:08] <JT-Work> http://www.kristitool.com/ktl/b-52.php
[21:11:53] <DaViruz> is bt/cat30 taper the same deal as iso30 taper?
[21:14:47] <JT-Work> * JT-Work heads back to the house
[21:14:47] <DaViruz> oh.. same taper, different pullstud/drawbar
[21:14:53] <archivist> taper I believe so except iso has a parallel bit at the small end
[21:42:27] <cradek> yes tapers the same - everything else is different
[21:42:42] <cradek> flange, drive dogs, drawbar/pullstud
[23:00:20] <Fox_Muldr> Fox_Muldr is now known as Fox_M|afk
[23:11:22] <jthornton> it appears that an application written in C using GTK+ will run on another computer that has EMC installed without having to copy a butt load of libs...
