[01:56:03] <NickParker> Is the 6i25 supported?
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Mesa_Cards doesn't list it under supported FPGAs, and under I/O card in pncconf I don't see it as an option.

[02:29:12] <mrsun_> hmm the piece i was going to make my collet chuck out of seems to be face hardened :/
[02:29:26] <mrsun_> it has now eaten two hss cutters :P
[02:30:52] <archivist> and those holders I found were too expensive you said :)
[02:31:23] <mrsun_> hehe =)
[02:31:35] <mrsun_> well regrinding hss steel isnt to hard :P
[02:31:47] <mrsun_> and i never said they were to expensive, i said i cannot afford it right now =)
[02:32:41] <Jymmm> mrsun_Just put on your fishnets and hit the corner
[02:33:11] <mrsun_> say what?! :P
[02:51:32] <Loetmichel> mornin'
[05:49:05] <MacGalempsy> morning
[05:49:11] <MacGalempsy> anyone around to help me out with a potentiometer question?
[05:49:55] <archivist> just ask the real question
[05:51:52] <MacGalempsy> ok. I have two 10K Ohm pots both with number 120-0009, one is to the Spindle Speed Override and the other is to the Feed Rate Override. the only difference is one is labled R1379743 and the other is R9732.
[05:52:14] <MacGalempsy> what does the R-value stand for?
[05:54:33] <archivist> dunno where you are reading that, probably nothing to worry about
[06:21:11] <MacGalempsy> it is stamped on the back of it
[06:21:35] <MacGalempsy> the only thing I am curious is if it is linear or logrithmic
[06:21:49] <MacGalempsy> for motor it should be linear?
[06:32:53] <skunkworks> you can measure it and see - measure the resistance at with the knob at half way...
[08:37:37] <Eran> I am thinking of using servo motors + arduino for my 3d printer
[08:37:44] <Eran> anyone has exprience with servos?
[08:38:14] <archivist> servos and linuxcnc, why bother with fartuino
[08:39:02] <Eran> archivist: do you have an example of 3d printer that uses linuxcnc?
[08:39:50] <kengu> https://www.google.com/search?q=linuxcnc+reprap
[08:40:07] <Eran> kengu: ya... dumm question
[08:40:36] <kengu> Eran: true but also my browser shows that on results page I have visited 50% of the first 10 results
[08:40:58] <Eran> kengu, archivist: thing is that arduino gives me the option to add lcd screen/etc
[08:41:13] <archivist> so does beaglebone black
[08:41:17] <Eran> kengu, archivist- and the question is why is linuxcnc is better?
[08:41:24] <kengu> Eran: i did not say that.
[08:41:35] <archivist> in built servo knowledge
[08:42:04] <Eran> archivist: I was thinking of using step/dir servo driver
[08:42:05] <Eran> http://www.geckodrive.com/geckodrive-brush-dc-drives/g320x.html
[08:52:17] <Eran> cradek: indeed
[08:54:21] <cpresser> Eran: nice work!
[08:54:31] <Eran> cpresser: thx :)
[08:54:54] * cpresser once started a 3d-printer design for foam
[08:54:57] <cradek> do you have pics of some completed parts that came out well? some of the ones in the video looked like stress tests (things with lots of unsupported holes)
[08:55:00] <cpresser> to print LARP weapons
[08:56:03] <Eran> cpresser: studiounder.com
[08:57:26] <Eran> how hard is it to control a 3d printer using beagleboard?
[08:58:39] <kengu> Eran: i could again point you to linuxcnc beaglebone -search as that is all i know about it. but it has been done atleast
[08:59:08] <cpresser> Eran: in order to use linuxcnc you need RTAI support in the kernel
[08:59:24] <cpresser> which is available for some ARM platforms
[08:59:36] <Eran> cpresser: don't even know what is RTAI :)
[08:59:49] <cpresser> Eran: Realtime extension for the kernel
[08:59:54] <Eran> cpresser: ok
[09:00:39] <Eran> cpresser: question is if there isn't much of a different between linuxcnc and arduino boards, then I will stick to what I know well
[09:01:26] <cpresser> Eran: basically: Linuxcnc is better :D
[09:01:34] <cpresser> you have way more features
[09:01:39] <Eran> cpresser: like?
[09:02:03] <cpresser> speed, programming in C and python
[09:02:07] <cpresser> user-interface
[09:02:47] <Eran> cpresser: user-interface is a good feature
[09:03:08] <archivist> more axes
[09:03:30] <skunkworks> Eran,
http://bb-lcnc.blogspot.com/2013/07/machinekit-2013-07-13-available.html
[09:03:32] <Eran> archivist: how about Raspberry Pi?
[09:03:34] <archivist> geared axes
[09:03:44] <archivist> pi struggles a bit
[09:04:08] <cpresser> Eran: better invest into a x86 motherboard (intel atom). its not that expensive.
[09:04:12] <skunkworks> Eran, Raspberry pi is pretty under-powered
[09:04:26] <Eran> ok
[09:04:54] <cradek> biggest feature for you is it can control servos without terrible step/dir limitations
[09:05:13] <Eran> cradek: yes, this is what I think too
[09:05:27] <Eran> cradek: all the rest is not really interesting for me (i'm not a programmer)
[09:05:36] <Eran> cradek: just want to use servos
[09:08:18] <cradek> then you probably want to use a pc and linuxcnc 2.5 and servo interface hardware that is known to work well
[09:09:00] <kengu> how are servos controlled?-)
[09:09:02] <Eran> cradek: I will investigate that
[09:09:08] <cradek> you could consider mesa H bridge type drives, or used-market velocity mode drives like the AMC
[09:09:09] <Eran> thank you
[09:10:07] <Eran> cradek: velociy mode?
[09:10:13] <Eran> cradek: *velocity
[09:10:24] <Eran> cradek: how do I find the right servo driver?
[09:10:36] <archivist> some servos also have a torque mode as well
[09:10:51] <cradek> velocity mode is how many industrial machines run servos
[09:11:13] <cradek> yes you've hit on the hard question now
[09:11:31] <Eran> cradek: will be here in 30 minutes
[09:59:02] <Eran> cradek: back
[11:59:36] <IchGuckLive> hi all B)
[11:59:40] <kengu> hello
[12:01:54] <_DJ_> hi
[12:02:06] <IchGuckLive> :-)
[12:15:15] <somenewguy> crud
[12:15:22] <somenewguy> how do i load a tool wihout using a tool change?
[12:15:35] <somenewguy> ie I just want to make slot 5 active
[12:15:50] <somenewguy> so when I use compensation it pulls from memory, and I don't need to spec each time
[12:22:29] <IchGuckLive> somenewguy: i m stil thinking about what you want to doo
[12:22:49] <IchGuckLive> loding a diameter is D
[12:22:57] <IchGuckLive> if you use CRC
[12:23:18] <IchGuckLive> so G41 D05 loads diameter tool5
[12:23:45] <IchGuckLive> G41 D01 loads Diameter of tool 1 into the interpreter
[12:24:06] <IchGuckLive> i think this is what you are asking for
[12:26:37] <archivist> somenewguy, define use slot 5
[12:26:59] <archivist> are you using gang tooling on a lathe?
[12:50:25] <andypugh> I wonder how widely-used Glade is? Very many of my queries on Google turn up LinuxCNC.
[13:39:34] <somenewguy> sorry I wandered off
[13:40:01] <IchGuckLive> as we got notice somenewguy
[13:40:04] <somenewguy> I am running a mill and dont use cutter comp too much cause its tricky and I'm new
[13:40:28] <somenewguy> but I have written a few chunks of code I trust that use cutter comp
[13:40:38] <IchGuckLive> its the way to do it as you can mil exact parts with different cutters
[13:40:47] <somenewguy> sso I would like them to simply use G41/42 and not spec what D
[13:41:06] <somenewguy> as I can load that manually and have it "stick" for the rest of the day
[13:41:20] <IchGuckLive> that will might kill you
[13:41:21] <somenewguy> manual tool change, no indexing on my collets, no touchoff or probe goodies
[13:41:33] <IchGuckLive> always use D for your G41/42
[13:42:05] <IchGuckLive> you can mill differend diameter for one cutter with the D
[13:42:11] <somenewguy> but if a subroutine is getting called and has a G41 in it, I would think you would not want to need to pass the D value to the subroutine
[13:42:31] <IchGuckLive> so rought takes lower D and exact a bigger one
[13:43:37] <IchGuckLive> G41 D1 ;call sub<> ; G41 D4 ;call sub <>
[13:43:44] <IchGuckLive> thats the way to do it
[13:44:16] <IchGuckLive> write your sub as you can change the D outwards
[13:45:19] <IchGuckLive> somenewguy:
http://www.youtube.com/watch?v=yM_nP9jEB24
[13:46:19] <IchGuckLive> Best of G41/G42 use is you can see your drawing messurments in the NGC
[13:47:07] <somenewguy> I am a little confused
[13:47:16] <IchGuckLive> i need to make another example with sub involved to change the D outwards of the sub
[13:47:18] <somenewguy> but then the D has to be hard-coded into each sub routine
[13:47:30] <IchGuckLive> no
[13:47:31] <somenewguy> can't watch the video, my connection is horrible out here
[13:47:55] <IchGuckLive> your D holds the offset from the path
[13:48:06] <IchGuckLive> as it is half the Diameter
[13:49:00] <IchGuckLive> your sub shoudt only include the normal path as the drawing showes and start /end somwhere outside the part or path
[13:49:20] <IchGuckLive> so you can jump in as many times on a sub call
[13:49:33] <IchGuckLive> somenewguy: are you in Europ USA ...asia
[13:51:53] <IchGuckLive> ok im off bye till tomorow
[13:53:06] <somenewguy> usa, thanks tho
[14:53:04] <jdh> cl
[15:19:40] <JT_Shop> somenewguy, if you don't use the tool table then use G41.1/G42.1
[15:27:23] <tjb1> Hello JT
[15:29:15] <JT_Shop> hi
[15:29:46] <tjb1> Sorry to inform but I have to take the plasma table over to the Mach side
[15:30:03] <jdh> *!* You're not an operator on #linuxcnc
[15:30:31] <tjb1> :)
[15:31:44] <tjb1> I live in a different area now and my dad doesn't know how to use Linux
[15:37:04] <Jymmm> tjb1: and remote access was thus created
[15:38:34] <tjb1> no internet
[15:40:30] <jdh> interesting concept.
[15:40:42] <Jymmm> then get him some interwebs
[15:41:06] <tjb1> satellite is too expensive
[15:41:08] <jdh> perhaps it's time to put him in a home.
[15:41:38] <Jymmm> jdh: lol, thats so fucked up =)
[15:43:59] <somenewguy> hey if he aint good for anything anymore..
[15:44:59] <Jymmm> tax writeoff as a dependant?
[15:45:04] <somenewguy> jt-shop, I do use the tool table, no real reaason tho, i suspect a G41.1 would be better, then everything is more obvious
[15:45:31] <somenewguy> also I saw that there is a iirc read only var that will tell you the diam of the currently selected cutter, maybe that is how I should do it here on out
[15:46:17] <somenewguy> question on something that tripped me up comeing here from mach3, is that my coordinate system keeps reverting to G54 during the day. I know it defaults to it on boot up, but why does end of a program revert to G54?
[15:46:36] <somenewguy> at first I thought only if I cancled/estoped, but it looks like hitting a M2 also reverts to the default offsets
[15:48:41] <jdh> http://linuxcnc.org/docs/html/gcode/m-code.html#sec:M2-M30
[15:49:06] <Jymmm> andypugh: Check this out (look at the manual pdf to see how it works)
http://www.harborfreight.com/brake-fluid-bleeder-92924.html
[15:50:19] <andypugh> Used to have one of those that you connected to the spare wheel as an air supply.
[15:51:36] <jdh> I have a Mighty-Vac I mainly use for leak testing scooters, but also works well for bleeding. The reservoir is too small though.
[15:51:40] <jthornton> somenewguy, have you read all the neat things M2 does?
[15:52:42] <Jymmm> andypugh: I like how it has a reservoir fill bottle too
[15:53:12] <Jymmm> andypugh: lol, spare tire, that's slick idea
[15:53:31] <jdh> like an old VW windshield washer
[15:53:47] <Jymmm> andypugh: I like that this thing has an bleeder screw adapter
[15:57:24] <somenewguy> no, I thought M2 was the simple one
[15:57:40] <somenewguy> I know there are more than one way to stop a cat in linuxcnc, I didn't learn the differences tho
[15:57:45] <jthornton> somenewguy, better read up on all M2 does
[15:57:56] <somenewguy> I just have a note here that says "use M2, is simple, good4now"
[15:58:17] <jthornton> if you don't have a preamble that sets up your environment each time you run a file your asking for problems
[15:59:38] <somenewguy> I don't even know what exchange pallet shuttle means lol
[15:59:55] <somenewguy> yes I need to re-create my old template I was using in mach3
[16:00:15] <jthornton> have you seen my tutorial on G code?
[16:00:17] <somenewguy> I had copied it, but have yet to put it onto this machine, just a pile of harmless pre and post amble commands
[16:00:21] <somenewguy> no, I would love to tho
[16:01:07] <somenewguy> andypugh: I made one of those bleeders for less from parts lying around, and a few from HF I think lol
[16:01:42] <jthornton> http://www.gnipsel.com/linuxcnc/g-code/index.html
[16:02:08] <somenewguy> I take it the M2 is the simpplest stop? I could roll my own, but I think I will just stick to a post-amble with annotations so I can remember what each item does
[16:02:24] <somenewguy> its impresive to me how quick I am remembering who does what, but still a cheat sheet is the best sheet
[16:02:54] <andypugh> The vehicles I work on most use steel rods. This is a steel rod fluid leak:
https://picasaweb.google.com/lh/photo/fD_QhcOeJDHeedZMgZS1RNMTjNZETYmyPJy0liipFm0?feat=directlink
[16:03:03] <somenewguy> thank you, I will read that over tonight so I can get better at this faster
[16:04:25] <somenewguy> what are you working on? I only caught the link to the HF one man bleeder
[16:12:54] <_DJ_> gn8
[16:13:28] <tjb1> Anyone know anything about magnetic clutches?
[16:13:34] <tjb1> Like torque limiting, not on/off
[16:37:43] <sliptonic> A couple months ago I started playing with the RTOS preview and then put it aside. I'd like to dust it off and play some more but it doesn't look like the rtos-integration-preview3-merged-into-master branch has change in a long time. Is there a branch that mirrors master more closely? Particularly looking for a fresher version of gmoccapy.
[16:40:35] * JT_Shop thinks no beeps is bad news
[16:41:35] * sliptonic agrees
[16:42:03] <cradek> sliptonic: just looking at
http://git.linuxcnc.org/gitweb?p=linuxcnc.git;a=heads -- unified-build-candidate-3 looks like a good ... candidate
[16:43:33] <sliptonic> Thanks. Will try it.
[16:52:35] <sliptonic> hmmm. Seems to be missing rtapi.conf.in in scripts.
[17:07:03] <JT_Shop> well it ain't the monitor
[17:30:04] <JT_Shop> put a speaker in and you get the beep codes
[17:33:05] <CaptHindsight> JT_Shop: have a link to your anodizing howto?
[17:34:11] <CaptHindsight> nevermind I found it by backup up through your site
[19:35:06] <MacGalempsy> evening
[20:14:32] <jp_mill> evening
[22:47:02] <MacGalempsy> anyone working on fun stuff tonight?
