[00:47:06] <fenn> chr0n1c: not really.. if you kill the X server it will bring down emc's userspace parts and that will stop the realtime stuff
[00:47:59] <fenn> you could theoretically bring up a new GUI an reattach to the realtime parts of emc, but your program wouldn't still be running because the new gui has no way to know where the old one left off
[00:48:31] <fenn> i'd recommend doing a memory test (one of the boot options)
[00:48:41] <chr0n1c> fenn, thanks for the input
[00:49:05] <chr0n1c> i haven't had any problems other than this one time...
[00:49:30] <chr0n1c> how does emc2 read the gcode, does it read it all at once and keep it it ram?
[00:50:28] <chr0n1c> i was jsut wondering if it was because of the size of the file (22 mb) or if it was because i was taxing the machine as much as i was
[00:51:09] <chr0n1c> i should have known better, i would never surf the web on a commercial cnc while a program was running, i shouldn't treat this machine any different
[00:51:32] <chr0n1c> i don't think i would even try to surf the web on a commercial cnc ;0
[00:51:57] <fenn> it processes the g-code file into simple moves (canon calls) and then queues those up in a buffer, but the buffer is only so big (i dont know if 22mb would fit) and sometimes there are decisions that make it impossible to queue
[00:52:45] <fenn> so.. did it finish?
[00:54:04] <chr0n1c> it would have finsihed, but i had a crazy move programmed in the file where it would go really fast for a sec and i had planned on adjusting the feedrate down, but i couldn't because it was locked up and then my cutter broke on that move.. :(
[00:54:26] <fenn> ah, programmer error :0
[00:54:38] <fenn> get a knob
[00:54:42] <chr0n1c> yup... the part it did cut was beautiful though
[00:55:29] <fenn> j/k i dont think a hardware knob is the solution to that problem
[00:55:36] <chr0n1c> i haev my Z apart making a new motor coupler, so i'll re-run the prog when i get the Z done and take some pics
[00:55:40] <chr0n1c> have*
[00:56:08] <chr0n1c> yes, the solution is: don't do anything but cut parts when emc is running :D
[00:57:31] <chr0n1c> i niticed my motor coupleing was slipping, which may have been a contributer to the cutter breaking as well
[00:57:36] <chr0n1c> coupling*
[09:30:31] <Guest31869> Hi
[09:30:36] <Guest31869> Guest31869 is now known as raven2
[10:32:02] <raven2> Hi
[10:32:55] <micges> Hi
[16:16:04] <jymm> archivist: see
[16:16:11] <archivist> i seed
[20:46:15] <alex_joni> good night all
[21:37:03] <Yof> hi! Is it possible to run a hotwire cutter with emc?
[21:37:26] <dmess> why NOT
[21:38:16] <dmess> i hope you have the necessary air extration equipment...
[21:38:56] <Yof> sure ... i will not run it in my apartment
[21:39:46] <dmess> it needs its own room... with a big ass fan in 1 wall
[21:40:16] <archivist> depends what its cutting
[21:40:40] <Yof> so it's possible to run two diffrent profiles for each side of the foam block?
[21:40:57] <dmess> 4 axis.. sure..
[21:42:04] <dmess> just imagine what a wire edm can do it can do about the same
[21:42:33] <Yof> nice, do you know if it possible to have emc controling a 5th axis to rotate the foam block?
[21:43:01] <archivist> yes
[21:43:05] <dmess> yes i do know... but its secret...
[21:43:32] <Yof> oh, i'll be quiet about it...
[21:44:15] <dmess> anything they can do we can do better..LOL
[21:44:48] <archivist> up to 9 axis http://www.linuxcnc.org/content/view/11/10/lang,en/
[21:44:57] <Yof> so is there some kinde of a guide howto set up emc to do 4 and 5 axis hot wire cutting?
[21:45:16] <dmess> ahh there he goes blowin' the limit switches.....
[21:45:57] <dmess> no but you cound be the author of the 1st 1
[21:46:40] <archivist> and google see if anyone else has made one yet and not told us
[21:46:48] <dmess> im thinking we will need sync M-codes for both 2 xis slides
[21:47:33] <Yof> i have done som google but only found 1 on youtube
[21:47:45] <Yof> with no contact possible
[21:49:55] <Yof> thanx any way.. goodnight
[22:06:07] <dmess> if the 1 cnc is in control of all axes and they can be programed on 1 line no sync required but i think we all should think about how to sync sets of 2-3 axes to one enother within a cnc program...
[22:07:07] <dmess> as in dual turret lathes ... wire machines... and this foam cutter..
[22:08:15] <dmess> like the old fanuc 18i's we had on the Nakamura's... M101 thru M199 wer to snyc the 2 turrets... make 1 wait for the other..
[22:10:33] <dmess> 1 crt 2 complete control panels of knobs and switches... and once the 2 chucks were within 12 inches the only button that worked was the BIG RED MUSHROOM
[22:11:19] <dmess> these were 18" chucks parting off 3" material
[22:22:04] <chr0n1c> do they make blue e-stop buttons? the one i have is black...
[22:22:21] <chr0n1c> ... and it's not hooked up
[22:22:39] <mdynac> yes they do automation direct
[22:22:56] <chr0n1c> sweet
[22:23:15] <mdynac> lighted even....
[22:30:32] <mdynac> oops, factorymation.com has them...
[22:30:55] <alex_joni> on yellow background
[22:31:06] <mdynac> any emc guys ouyt there today?
[22:31:31] <dmess> you got it Alex
[22:33:16] <alex_joni> "E-Stop standards that specify a yellow background, such as IEC 60947-5-5 and NFPA 79"
[22:33:57] <alex_joni> iqtest.dk <- have fun :)
[22:34:08] <mdynac> i need an input to emc to detect a wire break and shut the motion off, the pause button on axis is exactly what i need, where would i look in axis/emc to interface this input?
[22:35:40] <jepler> halui.program.pause is roughly the same as the pause button in the GUI
[22:35:53] <jepler> a rising edge on this pin will send an NML message to pause
[22:36:06] <jepler> halui.program.resume may also be useful to you
[22:37:28] <mdynac> thx, very cool,
[22:38:53] <mdynac> and for the icing on the cake, a gui box to pop up on the screen to say "wire break"
[22:46:46] <jepler> the closest I can come is a message which reads 'barn door open'. http://emergent.unpy.net/index.cgi-files/sandbox/error.comp
[22:46:47] <dmess> Just DO it
[22:48:33] <mdynac> cool, thx i"ll edit it accordingly......and i'll just DO the whole edm machine
[22:50:25] <dmess> what a concept.... i owner... to a project... your the Green belt on this one.. ; ) best success.. :)
[22:50:44] <dmess> one 1
[22:51:27] <mdynac> ell i already have an edm running emc....just putting the finishing touches on it....
[22:52:06] <dmess> i hoping i get a 4 inch Northfield Air chuck soon... for me lathe that isnt CNC yet
[22:52:52] <dmess> good for you... how are you dealing with power settings??? externally??
[22:53:44] <dmess> a cnc ram would be way cool to have again..
[22:54:16] <mdynac> i updated a Charmilles/Andrew EF22-330 edm with a MANUAL generator, the machine used a pdp8\a running it...
[22:54:25] <dmess> i used to orbit large threads that coulnt be cut
[22:54:50] <mdynac> baby steps my man....
[22:54:52] <jepler> bbl
[22:55:42] <dmess> have you cut with POCO ( graphite empregnated copper) before??
[22:55:58] <mdynac> i am building a small ' travel edm here at home tho....
[22:56:41] <dmess> poco makes the tank look like a french fry machine
[22:56:54] <mdynac> no sir, i modify, upgrade and repair edms, component level electronic tech here, i contract for edm network....
[22:56:57] <dmess> turn and burn....
[22:57:33] <dmess> i see.. so i screw up YOuR repairs...LOL
[22:57:49] <mdynac> yep
[22:58:48] <dmess> unfortunaly i had to fix and repair our old/new chinese pcs a kife too... so i only made myself some o/t
[23:00:15] <mdynac> the chinese edm they aquired at work is a piece of crap!!!
[23:00:35] <mdynac> a fastwire edm.....
[23:01:44] <mdynac> wire keeps going forward and backward over and over, no erosion during reversal of wire so it kinda steps thru the work....very very slow
[23:03:31] <dmess> ours were all sinkers... with x-y cnc so we sunk undersize 'trodes and orbited the material off
[23:04:02] <mdynac> ere they "edm solutions" brand?
[23:04:13] <mdynac> damn w key
[23:04:22] <dmess> chmere.. or something like that was the mane of the machine
[23:05:29] <mdynac> chmer......ah yes, you must have bought them from edmnetwork? they are made in taiwan, and a MUCH better machine than the chinese ones...
[23:05:30] <dmess> does it really matter they all come from the Chines machine tool and noodle factory
[23:06:26] <mdynac> no sir they don't, we go to taiwan often, to see the factory engineers...
[23:06:40] <dmess> looks right... hauled ASS when they worked... and went quit some times between b/d
[23:07:06] <dmess> so tiawan is safer than china??
[23:07:26] <mdynac> lets see chmer sinker edm.....ah yes z motor drive D-360 box, always shits the bed....
[23:07:59] <dmess> yup... replaced it 2 times in 3 yrs
[23:08:06] <mdynac> i consider the D-360 the 1200 dollar fuse......
[23:08:45] <dmess> but ANY job that went on it was cost at 300 dollars an hour ;)
[23:09:01] <mdynac> the sevice manager "larry" told me to stop fixing them, just throw them out....
[23:09:20] <mdynac> i laughed....
[23:09:35] <dmess> i think the last 1 cost 1800 and took 2 months to get and make work( new teck)
[23:09:48] <mdynac> got 6 stashed away so when they take 6 eeks to get i have good ones around.....
[23:09:59] <mdynac> larrys moron kid shawn.....
[23:10:22] <dmess> seriously
[23:10:35] <mdynac> larry is a very poor mamger
[23:11:05] <dmess> i am on a scrounge for little hardinge lathes CHEAP...
[23:11:30] <dmess> or associated tooling
[23:11:46] <mdynac> can't help you there
[23:12:45] <dmess> i scooped a Hardinge HSL 59 from work in a 5s auction.... i'd like a t/stock
[23:16:45] <dmess> i used to be in a mould shop that relied on edm ALOT
[23:17:26] <dmess> i have made some scarey assed 'trodes.... and sunke EM
[23:20:56] <mdynac> kewl, i've seen a lot, mostly jet engine stuff
[23:22:52] <dmess> jet stuff is the dreaded ROOT attatchment.. tapered dovetail right
[23:23:54] <dmess> brb
[23:25:45] <mdynac> just installed a Robofil 310F at TGM, the machine is making thousands of ROOTS for steam turbines!!!!
[23:43:45] <mdynac> bbl
