[02:13:45] <DJ9DJ> moin
[02:39:59] <JesusAlos> hi
[02:40:42] <JesusAlos> have a error in integration dxf2gcode with emc2
[02:41:37] <JesusAlos> sh: dxf2gcode_b02.py: not found
[02:41:50] <JesusAlos> but it's in the folder usr/bin
[03:04:40] <JesusAlos> I try it one and more time
[03:04:46] <JesusAlos> but not run
[03:04:52] <JesusAlos> I follow this steps
[03:05:02] <JesusAlos> http://code.google.com/p/dxf2gcode/wiki/Installation
[03:05:08] <JesusAlos> integration in EMC2
[06:11:16] <JesusAlos> Help please
[06:11:32] <JesusAlos> I configuring Pncconf linuxcnc
[06:11:39] <JesusAlos> with 7i77 mesacards
[06:11:50] <JesusAlos> enybody know somthing?
[06:12:06] <JesusAlos> enybody can help about this issue?
[06:14:44] <jthornton> the best support for pncconf is on the forum unless you can catch cmorley on here
[06:15:22] <jthornton> and we just ask the question here not if someone can help or not
[06:20:44] <JesusAlos> I need configurate a XY machine with Pncconf
[06:21:38] <JesusAlos> But when no assign z axis, wizzard say that i must be select z configuration
[06:23:06] <jthornton> can't you just have the z and delete it after your done
[07:34:41] * Loetmichel just looks like after a fight with a cat... had cut 100m copper foil tape (35µm) to 200 pcs. MAN is that "cutting edge"... *bandaid pates on all of his fingers*
[07:34:53] <Loetmichel> +ch
[07:35:23] <Jymmm> using what?
[07:35:55] <Jymmm> you teeth?
[07:36:04] <Loetmichel> scizzors
[07:36:10] <Jymmm> clinched butt cheeks?
[07:36:37] <Loetmichel> tip: dont let that foil tape run through your fingers when unspooling...
[07:36:40] <Loetmichel> *ouch*
[07:36:45] <Jymmm> Loetmichel: Dude.... paper cutter FTW!
[07:38:00] <Jymmm> Loetmichel: Never pass up the opportunity to use a guillotine or machete =)
[07:38:40] <Jymmm> (Unless you are chopping wood, then go for the saw instead =)
[08:13:28] <Loetmichel> chainsaw preferably
[08:13:37] <Loetmichel> :-)
[08:21:36] <Jymmm> Loetmichel: If you want to make kindling with a chainsaw, go for it =)
[08:53:25] <Loetmichel> *gnah*... cut again... and the cpper cuts are healing extremly slw :-((
[08:53:50] <Jymmm> Loetmichel: I was series about using the paper cutter
[08:53:53] <Jymmm> serious
[08:54:30] <Jymmm> Loetmichel: They work great for that kind of stuff.
[08:59:01] <Loetmichel> i am lamnating the stips nt cpper mesh shelding glass...
[08:59:08] <Loetmichel> *rumming*
[08:59:14] <Loetmichel> *rubbing n*
[08:59:41] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12454
[09:00:24] <Jymmm> glass or polycarb?
[09:00:52] <Loetmichel> glass
[09:01:26] <Loetmichel> 1,1mm glass sheets wit mesh fil n the back
[09:01:30] <Loetmichel> fil
[09:01:37] <Loetmichel> grrr foil
[09:01:38] <Jymmm> fill
[09:01:42] <Jymmm> oh
[09:02:18] <Loetmichel> <-clic on the pic to see it magnified
[09:02:52] <Jymmm> for?
[09:02:56] <Loetmichel> its a glass sheet with laser "etched" copper mesh n it
[09:03:00] <Loetmichel> shielding
[09:03:09] <Loetmichel> of tft displays
[09:03:39] <Jymmm> ah
[09:04:47] <Loetmichel> 3 busbars n the glasses dne.... 21 t g :-)
[09:04:55] <Loetmichel> to go
[09:05:21] <Loetmichel> (i think there is a cabe islation snipplet smewhere under ths laptp keyboard ;-)
[09:07:06] <Jymmm> look at the O and L =)
[09:07:32] <r00t4rd3d> more urn designs http://imgur.com/a/YD8EF
[09:12:23] <r00t4rd3d> im sick of people not flinching at my numbers either
[09:13:18] <r00t4rd3d> i told this lady 150 and she immediatly asked where to drop it off
[09:14:07] <r00t4rd3d> and she only seen a previous coffin ive done
[09:16:23] <Loetmichel> r00t4rd3d: if they are nt flinching yu are t cheap :-)
[09:16:32] <L84Supper> $150 for a custom etched coffin is a pretty low price in the US
[09:16:54] <r00t4rd3d> compared to a headstone and plot, i guess
[09:18:59] <L84Supper> IIRC that's about what they charge per letter on a headstone
[09:21:03] <Loetmichel> a tmbstone (typically granite over here) is a BIT harder to engrave than wood ;-)
[09:21:51] <r00t4rd3d> they sand blast them here
[09:21:58] <L84Supper> pretty much all done by CNC here
[09:22:12] <L84Supper> and ^^
[09:22:44] <r00t4rd3d> i think i am the only one in my town with a cnc machine
[09:22:51] <Jymmm> Loetmichel: Not really... I did this in granite http://i54.tinypic.com/k2mo7n.jpg
[09:23:29] <Loetmichel> laser?
[09:23:35] <Jymmm> yep
[09:24:01] <L84Supper> Jymmm: how many Chinese watts?
[09:24:17] <Jymmm> L84Supper: Made in USA =)
[09:24:32] <r00t4rd3d> assembled in usa
[09:24:52] <Jymmm> No, Actually Made in USA
[09:24:53] <L84Supper> USA watts x ~1.5 = Chinese laser watts
[09:25:02] <r00t4rd3d> peel off the made in usa sticker and CHINA is probably etched in it
[09:25:50] * Loetmichel had done some slate lately... but the mll bit didnt liked it
[09:26:15] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=13203
[09:26:33] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=13188
[09:27:09] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=13206 <- left Befre wrk, right : after one slate socket done
[09:34:13] <Jymmm> Loetmichel: http://i51.tinypic.com/2jttp2.jpg
[09:34:24] <Jymmm> Loetmichel: That is a LOT of pocketing
[09:34:48] <Jymmm> Loetmichel: Ever think about using soapstone instead?
[09:39:39] <Loetmichel> was a test
[09:39:53] <Loetmichel> test failed: nt ecnmcal with my tols ;-)
[09:40:40] <Loetmichel> made the 25 bases for the other trophys ut f wd :-)
[09:40:56] <Loetmichel> out of wood
[09:41:14] <Loetmichel> mom, get some compressed air in this keybard
[09:41:36] <Jymmm> Chuck, I'd like to buy a vowel... and O please, but could you deliver it to Loetmichel?
[09:47:12] <JT-Shop> damn brand new touch screen not working this morning...
[09:51:02] <Loetmichel> *ha* ... got the culprit: http://www.cyrom.org/palbum/main.php?g2_itemId=14052 ;-)
[09:51:58] <JesusAlos> joint 0 following error
[09:52:19] <Jymmm> JT-Shop: New toy for ya... http://www.karstsports.com/mingradcalca.html
[09:52:24] <JesusAlos> is the error in my machine when finish configuration
[09:52:27] <Jymmm> JT-Shop: Cheapest I've found.
[09:52:31] <JesusAlos> and start axis
[09:52:52] <Jymmm> JT-Shop: "Just add water"
[09:53:42] <JesusAlos> Appears when push start button
[09:55:11] <Jymmm> JT-Shop: http://en.wikipedia.org/wiki/Big-Bang_Cannon
[09:55:50] <Jymmm> JT-Shop: See, no need to have a big old heavy cannon... http://en.wikipedia.org/wiki/Bamboo_cannon
[09:56:40] <Loetmichel> Jymmm: *booom*
[09:56:42] <Loetmichel> :-)
[09:57:24] <Jymmm> Loetmichel: Well, that's all JT-Shop is going for anyway... He won't fire a projectile that I know of.
[09:57:53] <pcw_home> joint 0 following error is expected on a first time servo setup
[09:58:49] <JesusAlos> How resolve?
[09:59:00] <Loetmichel> i go thje opposite route... just ordered 60 300uF 300V caps for a coil gun ;-)
[09:59:00] <JesusAlos> http://imagebin.org/247280
[09:59:43] <Loetmichel> ... -> projectile without the bang :-)
[10:00:07] <pcw_home> you need first verify that you have feedback in the correct direction and then tune each axis
[10:01:19] <JesusAlos> I configurate Z axis, but don't have Z servo
[10:01:26] <JesusAlos> only XY axis
[10:01:29] <pcw_home> (assuming that you have previously verified that you can enable and move the servos with the analog output)
[10:02:56] <pcw_home> your error is X (joint 0 is normally X)
[10:03:10] <pcw_home> in X I should say
[10:03:42] <JesusAlos> ok
[10:04:04] <pcw_home> are the motor drives configured for analog velocity mode?
[10:05:22] <JesusAlos> yes
[10:05:27] <pcw_home> you can check this with pncconf's open loop test
[10:05:46] <JesusAlos> the X servo loop test only run in - no in +
[10:05:58] <JesusAlos> and the speed is low
[10:06:17] <JesusAlos> I can't increase the Fast Dac Sped
[10:06:24] <JesusAlos> only 10,00
[10:08:29] <pcw_home> if the drive speed is not symmetrical with + and - inputs its a drive fault or perhaps a drive setup error
[10:08:31] <pcw_home> if the 7I77 analog out is not symmetrical with +10 and -10 commands its a 7I77 fault or perhaps a wiring error
[10:08:47] <Jymmm> JT-Shop: Found some cheaper... http://cheapcarbide.com/cc/index.php?main_page=product_info&products_id=184
[10:14:29] <pcw_home> With this kind of problem its good to check one thing at a time
[10:14:31] <pcw_home> to check the drive by itself, _disconnect_ the drive from the 7I77,
[10:14:33] <pcw_home> enable the drive manually (by shorting the wires that went to the 7I77s ENA+ and ENA-
[10:14:35] <pcw_home> pins) and apply a small voltage (a 1.5V battery is good here) to the analog input pins
[10:14:36] <pcw_home> of the motor drive and see if the motor /axis move in either direction with equal speeds
[10:14:38] <pcw_home> when you reverse the battery leads
[10:17:05] <JesusAlos> 7i77 x axis output 0,1V in - direction and 0,05V in + direction
[10:17:24] <JesusAlos> in Y axis 10V in - and 10 in +
[10:18:03] <pcw_home> is that disconnected from the drive?
[10:18:13] <JesusAlos> is conected
[10:18:30] <JesusAlos> is the supply of 7i77 to device
[10:18:39] <pcw_home> is this with the open loop test?
[10:18:49] <JesusAlos> when push + putton in test loop
[10:19:07] <JesusAlos> yes
[10:19:14] <JesusAlos> with open loop test
[10:19:28] <pcw_home> try with the drive disconnected
[10:19:39] <pcw_home> maybe its a wiring error
[10:19:58] <JesusAlos> ok
[10:20:06] <JesusAlos> can desconected in hot?
[10:22:35] <JesusAlos> yes is wiring conection
[10:22:43] <JesusAlos> al reves
[10:23:02] <JesusAlos> backwards + -
[10:23:24] <pcw_home> Ahh that would short out the X analog out
[10:23:50] <JesusAlos> now error joint 1
[10:24:06] <JesusAlos> it runs ok in open loop
[10:26:50] <pcw_home> So now you need to check if the feedback is in the proper direction
[10:26:52] <pcw_home> is this a inch or mm machine?
[10:28:56] <JesusAlos> mm
[10:29:16] <JesusAlos> I try with both encoder direction
[10:31:00] <pcw_home> usually you get encoder direction correct first (so DRO reads correctly) and
[10:31:02] <pcw_home> _then_ you change the feedback polarity on the output
[10:31:19] <pcw_home> (for proper negative feedback)
[10:33:05] <pcw_home> you will probably need to loosen the ferror limits for initial tuning (set ferror and min-ferror to say 25mm)
[10:33:07] <pcw_home> so you can see whats going on before you get a following error
[10:40:52] <pcw_home> After you get the encoders reading with the with correct scale and direction and the
[10:40:54] <pcw_home> feedback direction correct, John Thornton has a very nice velocity mode servo tuning tutorial here:
[10:40:55] <pcw_home> http://gnipsel.com/linuxcnc/tuning/servo.html
[11:19:51] <JesusAlos> I stil no run Y axis
[11:20:13] <JesusAlos> there are no way to know the error?
[11:22:43] <JesusAlos> strenge
[11:23:12] <JesusAlos> I change the servo-driver in 7i77 X for Y
[11:23:24] <JesusAlos> and continus error joint 1
[11:24:27] <JesusAlos> befor the change, the axis X is join 0
[11:24:37] <JesusAlos> now Y axis is join 1
[11:24:54] <JesusAlos> sorry, Y axis join 1
[11:29:43] <Tom_itx> check your limit switches?
[11:33:00] <JesusAlos> the error appears without motors movment
[11:34:58] <pcw_home> but you can move the Y motor in the open loop test?
[11:35:54] <JesusAlos> yes
[11:36:01] <JesusAlos> the X and the Y
[11:36:09] <JesusAlos> without problem
[11:36:26] <pcw_home> did you widen the ferror limits so you can see whats going on?
[11:37:49] <JesusAlos> I don't know what is Ferror
[11:38:58] <pcw_home> I would read the integrators manual so you understand ferror before proceeding
[11:41:06] <pcw_home> http://www.linuxcnc.org/docs/LinuxCNC_Integrator_Manual.pdf
[11:41:08] <pcw_home> section 28
[11:41:51] <pcw_home> No Spanish unfortunately though there is a French version
[11:42:49] <JesusAlos> better English
[11:42:53] <JesusAlos> thank
[11:43:05] <JesusAlos> Go to change PC
[11:45:42] <pcw_home> Also section 3.2.10 (section 28 is PID only, no mention of ferror)
[12:13:24] <IchGuckLive> hi all B) O.O
[12:13:32] <Loetmichel> re @ home
[12:20:36] <tjtr33> needed a simple air cyl, but Festo always has cool stuff, this elephant trunk arm and gripper is Daleks^2 http://www.festo.com/cms/en_corp/11367_11435.htm#id_11435
[12:24:51] <IchGuckLive> yes the robotic stuff will be the chalange of this century
[12:25:07] <IchGuckLive> at 2020 everyone will have one
[12:25:28] <IchGuckLive> also the quadcopers for sky pictures
[12:28:26] <tjtr33> yesterday i read that the military wanted personal micro-copters, so ~"the soldier can toss it in the air and scout ahead"
[12:29:48] <Loetmichel> tjtr33: right... and personal Fuel cells to recharge the equipment?
[12:30:25] <Loetmichel> (PDA/tablet, CCC, Wireless communications, IR cam, etc)
[12:31:32] <tjtr33> and minature replicators, the space program needs to be able to make parts en-flight, and the univ of michigan already came & asked for dry-edm addons for micro mills
[12:32:07] <tjtr33> too much! back to work :)
[12:32:46] <Loetmichel> hrhr
[12:32:48] <IchGuckLive> tjtr33: http://www.virus4fun.ch/quadrocopter-schwarm-fliegt-synchron/
[12:33:03] <IchGuckLive> at 1:13
[12:33:12] <IchGuckLive> thats the most impressive
[12:35:27] <tjtr33> IchGuckLive, thx for the link, that really is sci-fi
[12:36:38] <Loetmichel> tjtr33: not scifi, reality ;-)
[12:37:01] <Loetmichel> i fly two of these... i know what they can do ;-)
[12:40:33] <IchGuckLive> and every drone can carry 500gr of cx
[12:40:49] <IchGuckLive> thats a big bumm
[12:40:58] <IchGuckLive> for a 100USD
[12:42:06] <IchGuckLive> Loetmichel: http://www.spiegel.de/netzwelt/gadgets/neuheiten-auf-der-spielwarenmesse-mehr-spass-dank-technik-a-881143.html
[12:42:19] <IchGuckLive> toys 3.0
[12:42:28] <L84Supper> http://www.ubuntu.com/devices/tablet a low cost UI for machines would be easy if only tablets included some GPIO, but it's not going to happen anytime soon
[12:43:33] <IchGuckLive> L84Supper: what about bluetouth
[12:43:54] <Loetmichel> IchGuckLive: djis are to small and have to small batteries
[12:44:12] <L84Supper> well they can be used just for the UI if you host the control on something else
[12:44:39] <Loetmichel> my copters have a flicgt time between 20 min and 45 min depending on payload and "flight style" ;-)
[12:45:02] <IchGuckLive> Loetmichel: at 5min and a 50km speed its enopf for that price
[12:45:02] <Loetmichel> -cgt+ght
[12:45:03] <L84Supper> I should have been more clear earlier, by stating "UI + control using a tablet"
[12:46:13] <IchGuckLive> L84Supper: the industrial Monitor pc's getting cheeper and cheeper with parport output
[12:46:27] <L84Supper> http://www.techject.com/
[12:46:35] <Loetmichel> L84Supper: most chap tabnlets have USB host... so where is the problem with GPIO?
[12:46:44] <Loetmichel> cheap
[12:47:18] <Loetmichel> oh, you menat: FAST gpio?
[12:47:26] <Loetmichel> okj, that is a bit of a challenge ;-)
[12:47:29] <Loetmichel> meant
[12:47:33] <L84Supper> yes, for real time control :)
[12:48:22] <Loetmichel> if you look inside a Tablet: should be possibnle to get some GPio out: http://www.cyrom.org/palbum/main.php?g2_itemId=11873
[12:49:16] <L84Supper> they generally don't route any, the pads are just left open
[12:49:52] <Loetmichel> but i would rahter use a cheap PC mini.itx board with W-Lan and then remote control the Board via network by the tablet
[12:49:56] <L84Supper> but if you find a tablet with GPIO please let me know
[12:49:59] <Loetmichel> already did that with VNC
[12:50:01] <Loetmichel> ;-)
[12:50:47] <Loetmichel> i.e. had the VNC client on the laptop and remote controlled the Mill from tha bathtub ;-)
[12:50:55] <Loetmichel> s/laptop/tablet
[12:51:43] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12521 <- like this ;-)
[12:51:57] <L84Supper> I can think of several ways that would be even more costly
[12:54:45] <Loetmichel> L84Supper: taht wasnt costly
[12:54:52] <Loetmichel> tha tablet is below 100 eur
[12:55:36] <Loetmichel> and a cheap intel mini-ity mainboard with cpi, lpt, ram and PicoPSU is also below 100 eur
[12:55:53] <Loetmichel> -y+x
[13:11:48] <IchGuckLive> its getting ice outside Brrrr
[13:13:48] <Loetmichel> IchGuckLive: WIMP! ;-)
[13:14:58] <DJ9DJ> hrhr
[13:22:12] <IchGuckLive> ok till tomorrow by
[13:22:16] <DJ9DJ> bye
[13:22:22] <DJ9DJ> damn, he is so fast :/
[13:52:16] <tjtr33> in FreeCad tutorials, it uses an embedded browser, yet theres no 'back' button, the only thing I found that responds is rt click & choose 'back' from menu
[13:54:04] <tjtr33> might be my default browser, ffox 17.0.1, has same controls on rt click ( and buttons as well )
[14:33:59] <Loetmichel> By the way: perspex on the minilathe is NO fun... -> http://www.cyrom.org/palbum/main.php?g2_itemId=14058 *spit* *Pfrrll*
[14:36:31] <tjtr33> Loetmichel, sorry, that picture really looks like your beard got caught in the lathe :)
[14:36:48] <Loetmichel> tjtr33: not long enough ;-)
[14:36:54] <cradek> yeah, my whole bathroom looks like that when I trim mine
[14:39:50] <archivist> http://visual.ly/how-much-you-can-trust-bearded-man
[14:43:33] <cradek> heh "very trustworthy" here
[14:43:47] <cradek> daily-maintenance shaving is for suckers
[14:47:16] <JT-Shop> your supposed to shave every day?
[14:49:05] <tjtr33> '... the baby fell out of the window, we thought that its head would be split, but luckily for the baaaby, it feel in a big pile of'
[14:49:06] <tjtr33> shaving cream, shaving cream, shave every day and you'll always look keen
[14:49:33] <tjtr33> fell damn it
[14:51:28] <DaViruz> i shave once or twice a month, it doesn't really bother me.
[14:51:32] <cradek> in my prison cell I SIT / with my coat-tails in the ... shade / shadow of my nose upon the WALLS / the women as they PASS / thrust their hat-pins up my ... sleeve / and the mice play hopscotch with my ... shoes
[14:51:52] <DaViruz> facial hair that is. shaving bothers me..
[14:52:11] <cradek> (it's harder to appreciate without the other verses that let you know what's supposed to rhyme)
[14:54:58] <archivist> cradek, I am second from left :)
[15:00:28] <BHSPiMonkey> archivist: I just noticed we have two channels in common. Were you by chance in Chicago last week? :)
[15:04:11] <archivist> BHSPiMonkey, no I watch from afar when I can, UK
[15:04:45] <BHSPiMonkey> ah
[15:05:01] <BHSPiMonkey> too bad, could've had a CNC breakout session :)
[15:05:56] <archivist> book collecting and cnc....I am a bit of a mixture :)
[15:06:24] <archivist> carting a cnc on a plane would be difficult
[15:06:30] <L84Supper> http://www.kickstarter.com/projects/1351910088/3doodler-the-worlds-first-3d-printing-pen?ref=card
[15:07:18] <L84Supper> BHSPiMonkey: anything exciting in Chicago last week?
[15:07:56] <cradek> archivist: I probably would be too, except for brillo-pad syndrome
[15:07:57] <archivist> Library coders getting drunk :)
[15:08:05] <BHSPiMonkey> L84Supper: ^
[15:08:16] <tjtr33> L84Supper, looks like a hand held extruder , meaning it could be cnc held as well
[15:08:24] <L84Supper> and I missed it, darn
[15:08:42] <BHSPiMonkey> I'd hesitate to call that thing a "3d printer", any more than I'd call a ballpoint pen an inkjet printer
[15:09:25] <BHSPiMonkey> methinks they're trying a little too hard to capitalize on the 3d printing popularity surge
[15:09:28] <L84Supper> hot melt glue gun
[15:10:34] <L84Supper> it's dumb things like this that confuse people, then when real 3d printing applications come up people think of repcrap and things like this
[15:28:19] <r00t4rd3d> ¿Cómo estás, mi loco amigo!
[15:28:50] <JesusAlos> yo bien
[15:29:05] <JesusAlos> ¿y tu?
[15:30:53] <r00t4rd3d> i only know some spanisg phrases :)
[15:30:58] <r00t4rd3d> err spanish
[15:31:33] <JesusAlos> pero has acentuado las palabras y todo
[15:31:42] <JesusAlos> eso es de campeones
[15:32:23] <L84Supper> Loetmichel: I understand, it's actually quite simple but my point is to eliminate the ~100 eur cost of the PC. Using a tablet with fast GPIO there would only be the cost of the tablet and the servo or stepper driver.
[15:33:05] <Jymmm> r00t4rd3d: You might update your spell checker, it seems to have have changed 'profanity' to 'phrases'
[15:33:20] <Loetmichel> L84Supper: right. But: then you loose tha ability to use the tablet as a pendant
[15:33:36] <Loetmichel> because it has to be wired to the steppers
[15:33:54] <L84Supper> Loetmichel: not a concern
[15:34:25] <Loetmichel> for you
[15:34:41] <L84Supper> for most of the applications
[15:35:00] <L84Supper> heh, I see you've been hanging out in #reprap
[16:01:16] <JT-Shop> I hate watching a pet who has quit eating and is just waiting for death
[16:02:59] <cradek> JT-Shop: really sorry to hear that. :-( it's easier on both of you if you take him to the vet and have him put down. it's so fast.
[16:03:24] <JT-Shop> he is not in any pain
[16:04:04] <Jymmm> Try offering him some of his favorite treats
[16:04:19] <JT-Shop> he won't eat anything anymore
[16:04:54] <Jymmm> has he been checked out by a vet already?
[16:05:16] <Jymmm> Is he drinking at all?
[16:05:19] <Loetmichel> L84Supper: right, i have all parts here for a Prusa. but no time to get it done. ;-)
[16:06:14] <Jensor> I am having trouble increasing the velocity onnmy z axis (axis2). Even though I increase max vel it sems to be limited to what axis 1 is set to. See the ini file @ http://pastebin.com/xdadKh2R
[16:06:17] <JT-Shop> he's been to the vet so many times I can't keep count
[16:06:39] <Jymmm> JT-Shop: Is he drinking at all?
[16:09:48] <cradek> Jensor: how are you measuring the resulting speed? what are you doing and seeing?
[16:10:20] <Jymmm> JT-Shop: If his lethargic, I've found that many times that's a lack of fluids and IV fluids can make a huge difference especially if not eating.
[16:10:38] <Jymmm> JT-Shop: just fyi
[16:11:13] <Jensor> The speed is on the display screen as well as xyz positions
[16:12:04] <Jensor> The jog speed seems tobe set ok by max vel but not G0 speed
[16:13:07] <Jymmm> JT-Shop: unflavored (clear) pedialyte and a sponge works too
[16:13:30] <cradek> so do you mean like G0 Z5 in mdi or in a gcode program? what speed does it go?
[16:13:40] <cradek> what version of linuxcnc?
[16:16:52] <Jensor> g0 z4 moves at 54 ipm accrding to screen display (.9 ips)
[16:17:17] <tjtr33> JT-Shop: sorry to hear that, it was good to you, be good to it
[16:17:59] <Jensor> Axis 2,3,5
[16:18:18] <JT-Shop> seems like any time a new cat wanders in an old one passes on
[16:18:43] <Jensor> Not sure how to determine version
[16:19:07] <cradek> Jensor: 2.3.5 is a version number, you can be sure by checking help/about
[16:19:23] <cradek> Jensor: maybe pastebin your hal files too
[16:20:23] <cradek> JT-Shop: I'll be thinking of you, I know you know the situation best and you'll do what's best for him.
[16:20:39] <Jensor> ok
[16:20:56] <cradek> gotta run, maybe someone else will have advice
[16:20:58] <JT-Shop> cradek: thanks, he is an old cat and it is his time

[16:32:28] <skunkworks> jensor - does it get up to a cruise phase in 4 inches?
[16:33:18] <Jensor> yes
[16:34:26] <Jensor> It gets there much less distance than that
[16:34:38] <skunkworks> Do you have max-velocity slider set?
[16:34:50] <Jensor> yes
[16:34:54] <skunkworks> to what?
[16:35:51] <Jensor> slider to limit it says 54 ipm
[16:36:15] <skunkworks> ok - that is a start..
[16:36:44] <Jensor> yet I can jog @ 90 ipm
[16:37:02] <Jensor> That is the max vel in ini file
[16:37:38] <JesusAlos> one question about 7i77 card.
[16:37:47] <skunkworks> so - are you sure the ini you are using is the one you posted? because you do have maxvelocity set to 1.5...
[16:37:52] <r00t4rd3d> http://www.pcduino.com/
[16:38:08] <Jensor> what determines what speed g0 moves at?
[16:38:14] <Jensor> yes same as posted
[16:38:35] <JesusAlos> I connect encoder output of my driver to 7i77 encoder inputs
[16:38:48] <JesusAlos> but, need eny GND reference?
[16:39:08] <JesusAlos> I thik the problem is about this question
[16:39:19] <JesusAlos> or driver that not run ok
[16:39:28] <Jensor> Y axis moves at 36 ipm (0.6 ips)
[16:39:31] <JesusAlos> tomorow I go to chek the encoder
[16:39:36] <JesusAlos> with hal scope
[16:39:58] <JesusAlos> ipm?
[16:40:00] <JesusAlos> what is this?
[16:40:08] <JesusAlos> inches ?
[16:40:16] <Jensor> inches per minute
[16:40:27] <JesusAlos> i run in mm
[16:40:54] <JesusAlos> My encoder is 1024 p/rev
[16:41:10] <JesusAlos> motor is about 3000rpm
[16:41:19] <micges> JesusAlos: you don't need gnd if encoder is differential (A+, A-)
[16:41:28] <Jensor> x axis moves at 54 ipm
[16:41:42] <JesusAlos> ok micges
[16:41:48] <Jensor> z axis moves at 54 ipm
[16:41:49] <JesusAlos> yes is A+A-
[16:42:19] <micges> JesusAlos: it is emulated by driver?
[16:42:40] <JesusAlos> Jensor: I don't know where you go
[16:42:51] <JesusAlos> yes, driver emulate
[16:42:58] <micges> so it should work
[16:43:14] <Jensor> skunkworks: I know I have it set to 1.5, it will jog nat that rate but not g0 at that rate
[16:43:17] <JesusAlos> I think the problem is a channel Z
[16:43:19] <JesusAlos> of encoder
[16:43:26] <JesusAlos> think that no ok
[16:43:34] <JesusAlos> Z+Z-
[16:43:39] <JesusAlos> cero of encoder
[16:44:11] <micges> JesusAlos: what problem?
[16:44:40] <JesusAlos> http://psha.org.ru/irc/%23linuxcnc/2013-02-19.html
[16:44:58] <JesusAlos> when try start buton axis, appears a error
[16:45:37] <DJ9DJ> gn8
[16:45:45] <JesusAlos> joint 0 following error
[16:46:13] <skunkworks> Jensor: are you doing all the editing on the linux machine?
[16:46:22] <JesusAlos> tomorow try with other servo
[16:46:29] <JesusAlos> one question
[16:46:52] <JesusAlos> where I find the pins in 7i77 of encoder
[16:47:04] <JesusAlos> A+A-B+B- ....
[16:47:17] <JesusAlos> I only found the encoder value
[16:47:55] <Jensor> skunkworks: It seems like max G0 is determined by the max vel of the x axis (0.9) because if I increase that then the z axis will move faster on G0
[16:48:07] <Jensor> yes on the linu8x machine
[16:48:23] <Jensor> linux
[16:48:30] <skunkworks> Jensor: show us your ini file.
[16:48:38] <skunkworks> * sorry - hal file
[16:49:02] <Jensor> See http://pastebin.com/xdadKh2R
[16:49:21] <Jensor> which one of the hal files
[16:49:30] <skunkworks> all of them
[16:49:34] <Jensor> ok
[16:51:31] <JT-Shop> Guess I should have explained just a bit more. There is tandem motors on the Y axis. When homing the machine will go until the Y1 side is on the limit then it waits for the Y2 side to catch up. This will square the gantry every time you home the machine. In parallel port I can do this but I can not find an effective wat to do it with the MESA boards.
[16:51:31] <JT-Shop> <chopper79> Since I do not have direct control of the stepgen using the MESa boards like I do with a parallel port
[16:51:31] <JT-Shop> <JT-Shop> best to ask on #linuxcnc channel
[16:51:31] <JT-Shop> <JT-Shop> I don't have a gantry with dual motors so I don't have any experiance

[16:57:33] <JesusAlos> It's A+A-B+B- etc
[16:57:46] <JesusAlos> I only found the encoder channel
[16:58:01] <JesusAlos> but not pin by pin encoder
[16:58:11] <JesusAlos> is for see encoder in halscope
[16:58:25] <skunkworks> Jensor: I am not seeing it.
[16:58:53] <skunkworks> Things look fine to me. I don't have a way to test the ini/hal here at the moment though
[16:59:36] <Jensor> What should determine the speed that g0 calls?
[17:00:19] <skunkworks> max_velocity in the traj section (limited by individual axis)
[17:00:26] <JT-Shop> JesusAlos: can you see any of the 7i77 pins?
[17:00:57] <skunkworks> but you say the max velocity slider is peaked out at 53ipm?
[17:01:06] <Jensor> that'shat i thought
[17:01:18] <JesusAlos> sure they are, but I not identified
[17:01:19] <Jensor> yes 54 ipm
[17:01:36] <JesusAlos> inly see a channel encoder input
[17:01:42] <skunkworks> that makes me think it is not reading the MAX_VELOCITY = 1.5 in your ini file
[17:01:44] <JesusAlos> only
[17:01:50] <JT-Shop> hm2_5i25.0.encoder.00.
[17:02:31] <JesusAlos> but, i need see signal by signal
[17:02:50] <JT-Shop> my machine is running touchy atm so I can not look at mine
[17:03:06] <JT-Shop> show hal configuration?
[17:03:27] <JesusAlos> I don't have EMC in this PC
[17:03:47] <JT-Shop> JesusAlos: you won't see the encoder inputs in hal
[17:04:12] <Jensor> Skunkworks: Yes, my system on a Bridgeport mill has been running fine and I recently wanted to drill a number of deep holes with many pecks and I tried to increse my Z max vel to speed things up is when I discovered this problem
[17:04:28] <JT-Shop> you can only see software encoder pin by pin
[17:05:02] <JesusAlos> and, how I can see the signal in halscope?
[17:05:25] <JesusAlos> a+a-b+b-c+c-
[17:06:40] <Jymmm> skunkworks: Dude, you're famous!!! http://www.grindtv.com/outdoor/blog/51073/tiny+frog+with+a+strange+squealing+cry+takes+internet+by+storm/
[17:10:53] <JT-Shop> JesusAlos: only with a real scope can you see hardware encoder pins
[17:11:03] <JT-Shop> they are not in hal
[17:12:31] <tjtr33> JesusAlos: what do you want to do? ( what is the reason you want want to see the raw encoder signals? ) there may be another way
[17:13:10] <JesusAlos> is only for analize signals with halscope
[17:14:01] <JesusAlos> my machine servo configuration have a problem, and want see the encoders
[17:15:14] <tjtr33> ok, then dont connect them to a mesa encoder input, hook them to generic inputs, they wont be hidden and you should be able to use halscope.
[17:17:07] <JesusAlos> Is a idea. Tomorow I try with real scope or tjtr33 says, and do other test, I tell you how it goes.
[17:21:05] <JesusAlos> GN
[17:21:23] <tjtr33> pcw_home, would it be ok to hook encoders to both encoder input and to generic input pins? ( just for slow debug )
[17:21:33] <tjtr33> JesusAlos, gn8
[17:23:13] <Jymmm> JT-Shop: http://www.youtube.com/watch?feature=player_embedded&v=Dp0Bt2cbcc8
[17:25:10] <skunkworks> I thiink you can view all pins as generic i/o
[17:25:17] <skunkworks> even the encoder inputs
[17:25:17] <JT-Shop> he has a non trustworthy beard
[17:25:38] <skunkworks> you just might not catch all transitions
[17:25:57] <JT-Shop> I don't think you can on muxed encoders
[17:26:06] <skunkworks> oh - good point
[17:26:18] <Jymmm> JT-Shop: lol, I wasn't aware that they had "trustworthy" beards, good to know. At least he doesn't squeak like skunkworks

[18:02:30] <Jymmm> maybe like those bank deposit hoppers... roll left load and split, roll right drop in pile
[18:02:46] <Jymmm> left load, center split, right drop
[18:03:33] <chopper79> Has anybody used the 5I25 with tandem motors on a single axis and used it to square the gantry during homing? Might not be the right question, but its a start.
[18:03:34] <JT-Shop> may work with perfect logs
[18:04:01] <JT-Shop> cho
[18:04:22] <JT-Shop> chopper79: pastebit your hal
[18:06:10] <chopper79> This is my current hal I use for my parallel port setup. I am converting to the 5I25 and need to perform the same logic as in the paralle port. the fact that I do not have use of step and direction signals in the .hal for the 5I25 config is making this very difficult to pass it correctly. Here is my current .hal that I use on the parallel port. http://pastebin.com/4k5dD0rM
[18:06:35] <chopper79> Not use of but control of the step and direction pins in .hal
[18:10:13] <chopper79> The logic I wrote in this will allow tandem motors on my Y axis controlled from just the Y stepgen functions. This allows me to use one key to move both motors and also allows me to square the machine on homing. I am having a tough time converting this logic over to the 5I25 configuration im working on. With no way to utilize the step and direction signals is what is making this difficult or me to figure out.
[18:12:08] <chopper79> It was suggested to use just the enable signal for the Y axis and then break it out to another stepgen (A axis) to gain the same fucntionality. It sounds correct but nothing is allowing me to correctly make it function as it did with a parallel port
[18:12:47] <chopper79> using and, or, not gate to do the breakout
[18:16:47] <tjtr33> chopper79, if i read correctly, the logic is to inhibit the leading joint when it hits the switch, but allow the 2nd joint to catch up, till both are 'just' at the trip points
[18:19:20] <tjtr33> the same logic might be done by incrementally moving a small unit of distance ( not a step, but a small unit of measurable distance ) in a loop till 1st then 2nd are at the switch points
[18:19:58] <tjtr33> then back 'em off and repeat with smaller distances, then set machine 0
[18:20:44] <tjtr33> ( measure twice, zero once :)
[18:24:26] <tjtr33> you wont make it work with the same nets and comps, you will make it work with same idea. an 'event' of the 1st swx change will inhibit the 1st joints motion, yet allow the 2nd join to seek its switch
[18:24:40] <tjtr33> same idea, different nets and comps
[18:31:01] <chopper79> tjtr33.... You did read that correctly.
[18:33:09] <Jymmm> JT-Shop: I don't see where the cnc attachment is for your log splitter? No sense and detect potantial canidates, laser guided splittting for the maximum yield, the robotic arm that picks up and un/loads the splitter?
[18:33:40] <JT-Shop> http://www.youtube.com/watch?v=cUf4F9VXo_s

[18:45:27] <JT-Shop> http://forecast.weather.gov/MapClick.php?lat=36.7378524&lon=-90.48799159999999&site=all&smap=1&searchresult=Poplar%20Bluff%2C%20MO%2063901%2C%20USA
[18:46:31] <Tom_itx> you may be on the edge of it
[18:49:09] <Jymmm> The gal is pretty good, but man the whining that splitter is making is just eery http://www.youtube.com/watch?v=M1eIgBZqeY0
[18:52:38] <Jymmm> JT-Shop: DONT TRY THIS AT HOME http://www.youtube.com/watch?v=HPWaTaKoMqU&NR=1&feature=endscreen
[18:53:24] <JT-Shop> http://www.youtube.com/watch?v=7fWo0P0MdJM
[18:55:06] <Jymmm> no way thats real
[18:55:14] <JT-Shop> yea
[18:55:22] <tjtr33> the ax is 'flicked' , thats why it looks as if she slapped it sometimes
[18:55:43] <Jymmm> crazyglued or something
[18:55:46] <JT-Shop> there is two ways to split with a double bit axe, the flick or the angle
[18:56:10] <JT-Shop> straight grain wood splits easy if you know how
[18:56:26] <Jymmm> and seasoned for 5 years =)
[18:56:41] <JT-Shop> if you watch the axe it is horz at the end
[18:57:08] <Jymmm> I saw that, that's what made me think it's fake
[18:58:24] <JT-Shop> no trick it is a way to split, I was taught that way when I was 15
[18:58:37] <Jymmm> I stil think I like the tire screw splitter.... any car, anywhere, no hassel
[18:58:46] <tjtr33> thats the flick, a twist right after contact, dont try to go thru
[19:00:01] <tjtr33> shes good even if its well dried
[19:00:20] <Jymmm> floor jack, 4-way tire iron, the screw splitter and you're good to go.
[19:00:48] <Jymmm> bonus is 1/4" plywood shield to save the paint job
[19:01:50] <Jymmm> I wonder how much HP would be needed w/o a car?
[19:02:52] <Jymmm> JT-Shop: I think you already saw the wood gas heater
[19:03:33] <nevyn> I used to have to split redgum for kindling.
[19:03:45] <nevyn> I was very careful which block from the stack I selected
[19:03:55] <Jymmm> redgum?
[19:03:56] <nevyn> no knots or branches nice straight grain.
[19:04:11] <Jymmm> ah
[19:04:24] <Jymmm> why so selective?
[19:04:57] <nevyn> because I was splitting it by hand with a blocksplitter.
[19:05:07] <Jymmm> and?
[19:05:14] <nevyn> to turn something the size of a breadbox into 1/4 inch sticks
[19:05:33] <Jymmm> oh, maye you need this then http://www.youtube.com/watch?v=HPWaTaKoMqU&NR=1&feature=endscreen
[19:06:07] <Jymmm> seems that would make great safe kindling
[19:06:17] <Jymmm> little effort and still have your fingers
[19:08:06] <Jymmm> Eeeesh http://www.youtube.com/watch?v=37gH9SObKVA&feature=endscreen&NR=1
[19:12:43] <Jymmm> JT-Shop: AH HA! NOW I know why the reenforcment,,, it's a tractor attachment... http://www.youtube.com/watch?v=GAdWb9pdZNw
[19:15:23] * JT-Shop goes inside now
[19:15:38] <Jymmm> laters gracie
[19:15:41] <JT-Shop> say goodnight Gracie
[19:15:46] <Jymmm> ;)
[19:15:57] <r00t4rd3d> wow, Android for routers now like ddwrt/openwrt
[19:15:57] <r00t4rd3d> http://www.droidifi.com/
[19:19:27] <Valen> networking seems to not be big on the android features list
[19:25:42] <Jymmm> lathe log splitter http://www.youtube.com/watch?v=QMkL6UQp2fY&NR=1&feature=endscreen
[19:30:00] <Jymmm> Redneck log splitter (ouch) http://www.youtube.com/watch?v=40sCGb678sQ&NR=1
[19:35:52] <nevyn> Jymmm: I still like this one: http://www.youtube.com/watch?v=hhmKBDIAXd0
[19:44:54] <nevyn> Jymmm: this is also interesting : http://www.youtube.com/watch?v=_olacH1hlWg
[19:56:48] <Jymmm> Fastest Firewoood Splitter in the world! http://www.youtube.com/watch?v=5pLiJMZjQDw&feature=related
[19:58:50] <nevyn> Jymmm: I think the others I had were faster
[19:59:04] <Jymmm> haven't got there yet =)
[19:59:05] <nevyn> the on that took a 6' round and split it in a single shot
[19:59:17] <Jymmm> whats the tumbler for?
[19:59:49] <nevyn> http://www.youtube.com/watch?v=XAqi6Zb_c6E
[20:00:02] <Jymmm> the 1st is cool
[20:00:08] <nevyn> Jymmm: desplinter
[20:00:21] <Jymmm> ah
[20:00:27] <Jymmm> starting 2nd now
[20:00:27] <nevyn> it drops all the kindling bits out
[20:00:35] <Jymmm> nice
[20:01:46] <Jymmm> ah, like the green one I showed earlier. I like it too
[20:04:19] <Jymmm> nevyn: I like the first one the best, looked trailer portable too
[20:04:50] <Jymmm> free kindling and sawdust for the garden =)
[20:05:36] <Jymmm> Though large redwood bark chips work best for weed control.
[20:05:40] <nevyn> the bit I don't get is what the cost/benefit is..
[20:05:57] <Jymmm> how so?
[20:06:08] <nevyn> so we would burn ~ 8m3 of firewood a year in a 40square house
[20:06:27] <nevyn> that's about 4hrs work for any of those big machines
[20:06:50] <nevyn> it was only a weekend work for 3 men and a simple axial splitter.
[20:07:08] <Jymmm> Ah, well think of this... you have the forest, bring that gut in for say $300 and have him do all that for you in a few hours.
[20:07:33] <nevyn> so it becomes a hire in the machine + guy problem.
[20:07:43] <nevyn> which might be worthwhile
[20:08:04] <nevyn> I suspect we did hire someone in to cut the rounds...
[20:08:10] <Jymmm> yeah, especially in certain areas of the country
[20:09:22] <Jymmm> cut and split all at once, sounds like a good deal to me
[20:09:55] <nevyn> so everything I've seen these guys splitting seems.. light
[20:10:05] <nevyn> and crappy.
[20:11:35] <Jymmm> Yeah, I really wouldn't know. I have touch/thought of splitting firewood in eons
[20:11:41] <Jymmm> except for camping
[20:11:47] <nevyn> http://www.gumtree.com.au/s-ad/bellevue-heights/miscellaneous-goods/firewood-river-redgum/1013332339
[20:11:52] <ReadError> 3060 extrusion is much larger than expected ;o
[20:13:15] <jdh> is it 30 by 60?
[20:14:18] <ReadError> 3"x6X
[20:14:21] <ReadError> 6"*
[20:14:58] <nevyn> hrm that's bigger than I would have thought
[20:15:52] <ReadError> yea its a very stout piece of aluminum
[20:18:19] * nevyn would have thought mm not "
[20:18:36] <nevyn> as in millimeters not mils
[20:21:04] <ReadError> its maybe 40-50lbs
[20:21:15] <ReadError> 4' long i think
[20:22:28] <nevyn> heh
[20:34:05] <Jymmm> nevyn: cut, feed, split, de-kindle, all sounds good to me
[20:34:16] <Jymmm> and pile too =)
[20:35:24] <Jymmm> nevyn: maybe for an extra $40 there might be a stacker option too =)
[20:36:37] <tjtr33> the short stroke hydraulic splitters, like a cyclical hammer blow... if the end of stroke had a twist - you get the barefoot girl's flick.
[20:57:33] <AR__> so after building my mill
[20:57:40] <AR__> i realize it's a piece of shit
[20:57:47] <AR__> i dont even know what to make with it now
[20:57:57] <Valen> lol
[20:58:12] <AR__> i really had no reason to build it other than an obsession with wanting it
[20:58:28] <AR__> oh well
[20:58:56] <cradek> well then the obvious thing to do now is build a better one
[21:02:30] <AR__> omg
[21:04:39] <AR__> that was kindof my plan until i went over budget to build this one
[21:07:39] <Valen> whats not good about it?\
[21:10:09] <skunkworks> actually - the obvious thing is to buy a old cnc with a dead control :)
[21:10:11] <ReadError> improve on it
[21:10:25] <ReadError> r00t4rd3d's was made of MDF
[21:10:30] <ReadError> now he has it all riced up
[21:24:53] <r00t4rd3d> AR__, why is it a pos?
[21:25:34] <AR__> i dunno
[21:25:53] <AR__> just cause i'm tired of looking at it i guess
[21:26:38] <nevyn> skunkworks: just make sure that there's not too much slop in the spindle bearings...
[21:26:45] <nevyn> most other things are fixable ;)
[21:27:58] <r00t4rd3d> ar cant you get it to work ?
[21:30:56] <r00t4rd3d> AR__
[21:31:04] <AR__> ?
[21:31:08] <AR__> nah it works fine
[21:58:59] <abetusk> is there a language specification for g-code somewhere?
[22:05:00] <Tom_itx> for linuxcnc or in general?
[22:11:28] <Tom_itx> http://technisoftdirect.com/catalog/download/RS274NGC_3.pdf
[22:17:16] <mrsun_> hmm using the cnc mill to grind single point gear cutters maybe :P
[22:17:35] <mrsun_> just program the cutting path with extremly light cuts and grind them ? :P
[22:17:41] <mrsun_> think that would be possible ?
[22:18:01] <mrsun_> maybe hard to tell how much material it will actualy take of per pass when grinding ?
[22:20:05] <abetusk> Tom_itx, thanks
[22:57:04] <Tecan> finally! linux games on steam... http://i.imgur.com/xuJdgYn.jpg
[22:57:19] <Tecan> they run well too
[22:57:30] <Tecan> sales on today for them
[22:57:46] <Valen> interesting
[22:58:06] <Valen> do games i have in windows that are now linuxy carry over?
[22:59:31] <Tecan> yes
[22:59:36] <Valen> handy
[23:00:32] <Valen> productivity reduction imminent
[23:00:50] <Valen> rofl
[23:00:51] <Valen> or not
[23:00:57] <Valen> 175mb to install steam
[23:08:12] <Tecan> hehe
[23:13:47] <tjtr33> abetusk: http://code.google.com/p/rs274ngc/ for the vrsn used in linuxcnc, others use rs274 and rs274x
[23:17:45] <abetusk> sorry for my ignorance, but what does the code do? Is there any documentation, other than the source?
[23:18:10] <tjtr33> danielfalck, i used FreeCad again today, very nice
[23:19:22] <tjtr33> abetusk, it describes the path for a tool to move along ( and velocities and machne tool function like flush and in general, the things you'd do by hand, but very explicitly)
[23:20:36] <abetusk> I'm still unclear as to what this program's (or library's?) function is
[23:20:52] <tjtr33> abetusk, for a simple overview , there's the gcode reference in linuxcnc, its on the main desktop menu 'Linuxcnc G-Code Quick Reference'
[23:21:39] <abetusk> it sends out stepper driver signals over the parallel port? How does it "interpret" g-code? What does it interpret it to?
[23:22:49] <tjtr33> no, gcode is not that low level, its like driving instructions, start in CHicago, turn left 3 miles, stop, take lunch, go north 3days... like that
[23:23:03] <abetusk> I understand that.
[23:23:07] <tjtr33> the stepper signal are way below that level,
[23:23:13] <abetusk> So what is this program doing?
[23:23:54] <tjtr33> this program? what do you mean? linuxcnc?
[23:24:46] <abetusk> rs247ngc. I just compiled it using the Makefile provided and it created canon.o. What is canon.o? Is this a library of some sort?
[23:24:54] <abetusk> the link you provided
[23:25:49] <tjtr33> rs274ngc is not a program, it is a language. linuxcnc reads that language and coordinates machine functions and motion to accomplish the task described by the language
[23:26:21] <tjtr33> you say what you want in rs274ngc, linuxcnc executes your commands
[23:26:59] <abetusk> I feel like we're running around in circles. Anyway, the spec. there was the one Tom_itx already provided, but thanks anyway.
[23:29:24] <tjtr33> look at the diagram in section 4 of http://www.linuxcnc.org/docs/html/code/Code_Notes.html
[23:37:49] <tjtr33> danielfalck, http://imagebin.org/247376 i learned not to chamfer incomplete hole edges, where they might be cliped by another chamfer :) nice app thx!
