#emc | Logs for 2007-05-06

[00:08:35] <gene> Ok, I put linkps parport.0.pin-10-in => motion.probe-input in the standard_pinout.hal file, but its barfing, apparently on the motion.probe-input portion
[00:09:25] <gene> Humm, I need a newsig for that too I guess
[00:12:59] <gene> and that isn't going to worrk, with emc running, a show halconfig says parport pin 10 is an out, for spindle control, which I don't have.
[00:15:56] <ohiopctechDOTcom> there is some lines for a spindle line in the ini, comment it out
[00:16:08] <ohiopctechDOTcom> ??
[00:16:42] <ohiopctechDOTcom> or the hal file maybe not the ini
[00:19:53] <gene> Just did that, and I can watch the pin with halshowconf, but I still don't have it hooked to the g38.2 logic. How is that done?
[00:20:53] <ohiopctechDOTcom> not sure...
[00:21:06] <ohiopctechDOTcom> i haven't touched probing yet here
[00:21:33] <gene> reading furiously...
[00:21:44] <ohiopctechDOTcom> newsig &linksp?
[00:21:50] <ohiopctechDOTcom> my guess
[00:22:02] <ohiopctechDOTcom> or linkPP i meant
[00:22:24] <ohiopctechDOTcom> or link ps
[00:22:30] <ohiopctechDOTcom> linkps*
[00:24:07] <gene> to the motion.probe-input (bit) to what? linkps motion.probe-input => ??
[00:31:39] <toastydeath> that almost sounds like an innuendo.
[00:36:09] <gene> chuckle
[00:39:02] <ohiopctechDOTcom> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Probing_With_EMC
[00:43:19] <gene> Thanks. But that has to set some sort of a record for brevity. And no manpage for emcprobe
[00:43:41] <ohiopctechDOTcom> lol.. very brief
[00:43:50] <ohiopctechDOTcom> that's all i can teel ya though
[00:43:54] <ohiopctechDOTcom> tell*
[00:44:05] <gene> and 'command not found' here...
[00:45:45] <ohiopctechDOTcom> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Preventing_Probe_Crashes_Using_HAL
[00:46:29] <CIA-8> 03jmkasunich 07TRUNK * 10emc2/src/rtapi/ (rtai_rtapi.c rtapi_common.h rtapi_proc.h rtl_rtapi.c): SMP optimization: run RT tasks on last CPU, not first one
[00:50:01] <gene> I read that one in passing too. That wiki needs quite a bit of tlc :)
[00:50:36] <ohiopctechDOTcom> when you ifnger it out, won't you make a wiki describing your steps?
[00:50:41] <ohiopctechDOTcom> finger it out*
[00:50:56] <ohiopctechDOTcom> i will need to hook a probe up soon.. after i build it...
[00:51:02] <ohiopctechDOTcom> ;)
[00:51:04] <gene> probably if I have write privs
[00:51:56] <ohiopctechDOTcom> sweet
[00:54:41] <gene> Dunno if they trust this old fart yet. I'm going to see if I can trip it dong a g38.2 from the mdi
[00:57:19] <gene> from the mdi, its slowly descending, but I can't trip the sensor yet.
[00:59:11] <ohiopctechDOTcom> was there plans on a website for the probe or did you jsut do it from a description?
[00:59:46] <gene> Dean Hedin had sent me a link to a pix of one he made, and I basicly did a freehand copy.
[01:17:25] <gene> cold & raining here, I think I'll call it a day, thanks everybody
[02:05:49] <cradek> http://www.kansas.com/static/slides/050507tornadoaerials/
[02:05:53] <cradek> wow.
[02:06:18] <SWPadnos> damn
[02:06:51] <SWPadnos> tough silo in photo 7
[02:07:04] <cradek> yep
[02:07:38] <cradek> sometimes I wonder why are our houses are wood instead of concrete.
[02:07:45] <SWPadnos> $$$$$
[02:07:45] <cradek> (because we like them that way I guess.)
[02:11:06] <cradek> http://www.kansas.com/static/slides/050507tornado/images/050507tornado_mb5.jpg
[02:11:54] <tomp> (gun drills move the work and keep the spindle still, its the only way to drill long straight holes according to a few hundred years of experience, ... and use a load of flush)
[03:14:13] <ohiopctechDOTcom> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?ToolTable what's up with the endmills that have threads on the end of them.. are they for a special machine?
[03:26:19] <jmkasunich> thats a europe thing
[03:26:30] <jmkasunich> they screw into the collet
[03:28:52] <ohiopctechDOTcom> oh
[03:29:11] <ohiopctechDOTcom> i thought maybe it was an overseas thing when i read 18mm on them
[03:29:51] <cradek> that's not a great picture - the "length" is deceptive
[03:32:06] <jmkasunich> length is usually measured from the spindle nose, right?
[03:32:12] <jmkasunich> front of collet, not back of endmill
[03:32:35] <cradek> or a reference tool - it can be pos or neg
[03:33:02] <cradek> but the back end is one of the wrong places to measure from...
[03:33:11] <jmkasunich> right
[03:35:05] <SWPadnos> wouldn't most people using tool length compensation define the actual cutting length (or exposed) length of the tool?
[03:35:10] <SWPadnos> ie, no negative numbers
[03:35:19] <cradek> probably
[03:35:25] <SWPadnos> ok, just checking :)
[03:36:21] <cradek> but I can see an argument for using all negative numbers - if you turn length comp off, your tools don't smash into anything
[03:37:20] <ohiopctechDOTcom> i really need to make some sort of solid holder and fill out that tool table.. would be awesome for this little machine...
[03:37:27] <cradek> with the tool 'probing' stuff I recently did, the length comp can turn out to be anything, it doesn't matter
[03:37:30] <toastydeath> swpadnos:
[03:38:41] <SWPadnos> !
[03:38:41] <ohiopctechDOTcom> maybe i can super glue my bits to one leg of the collet...hmmm
[03:38:41] <toastydeath> some machines have a machine 0 axis that is not at the limit of an axis
[03:38:41] <cradek> ohiopctechDOTcom: you have just a collet and loose tools?
[03:38:41] <ohiopctechDOTcom> cradk yes
[03:38:42] <ohiopctechDOTcom> cradek*
[03:38:41] <cradek> did you see the recent thread about using probing to measure and compensate for random tool lengths?
[03:38:41] <ohiopctechDOTcom> i have a few collets
[03:38:41] <toastydeath> also some tools like roller burnishers
[03:38:41] <toastydeath> for complex forms
[03:38:47] <toastydeath> may have a negative length
[03:38:49] <cradek> http://cvs.linuxcnc.org/cvs/emc2/nc_files/tool-length-probe.ngc?rev=1.1
[03:38:57] <ohiopctechDOTcom> i read it, but i didn't retain much from that thread
[03:39:57] <cradek> my machine came with three collets - 1/8, 3/16, 1/4 - if emc could do this back when I started using it, maybe I wouldn't have bothered with tool holders
[03:40:28] <cradek> executive summary: after loading a tool, the gcode pokes a switch with it to measure it
[03:40:46] <jmkasunich> * jmkasunich pokes cradek
[03:40:58] <cradek> hey
[03:41:08] <jmkasunich> with a trout!
[03:41:38] <ohiopctechDOTcom> yeah... so i would just copy the lines into my code where i need a tool change.. and have a block with a switch setup just inside my cutting limit?
[03:41:53] <cradek> the tool length thing was another one of those where several people asked for it, I made it work and posted instructions, and then there was total silence
[03:42:06] <jmkasunich> people never say thank you
[03:42:09] <cradek> ohiopctechDOTcom: yes that's pretty much it
[03:42:25] <ohiopctechDOTcom> * ohiopctechDOTcom says thank you most of the time
[03:42:26] <cradek> jmkasunich: I'd rather see "yay, works for me" than thank you
[03:42:40] <jmkasunich> yeah
[03:42:49] <jmkasunich> some form of acknowledgment anyway
[03:42:53] <cradek> I bet it takes some time to get set up, they'll be back
[03:42:54] <ohiopctechDOTcom> if i forget to say thanks for helping me with something... THROW A BRICK AT ME!
[03:43:00] <cradek> haha
[03:43:11] <jmkasunich> be carefull what you ask for
[03:43:15] <jmkasunich> I might just do it
[03:43:18] <jmkasunich> ask my brother
[03:43:18] <ohiopctechDOTcom> HA!
[03:43:20] <ohiopctechDOTcom> * ohiopctechDOTcom ducks
[03:44:13] <jmkasunich> we were early teens (at most) on a picnic or some such thing - he asked me for a brick, so I tossed it to him - he needed stitches in his shin...
[03:44:29] <jmkasunich> kinda ruined the picnic
[03:44:33] <ohiopctechDOTcom> anyone have one of those crappy vhs-c tape adapters to make it a full size vhs? i could copy some of the vidoe i been taping with this old camcorder to my pc and youtube it
[03:44:58] <ohiopctechDOTcom> * ohiopctechDOTcom retracts statement about the brick
[03:45:12] <SWPadnos> nerf bricks are OK
[03:45:24] <ohiopctechDOTcom> yeah.. or those nerf shotgun things
[03:46:09] <ohiopctechDOTcom> GENE! did you get yer probe workin?
[03:46:24] <ohiopctechDOTcom> oh he said he was leavin
[03:46:28] <ohiopctechDOTcom> ...
[03:50:10] <ohiopctechDOTcom> i think i may just take the camcorder apart and rig up some rca jacks instead of having to buy a crazy din cable from japan
[03:50:25] <ohiopctechDOTcom> ...and then i can get vids of the machine onto my pc
[03:50:44] <ohiopctechDOTcom> my webcam won't work under *buntu
[03:50:48] <SWPadnos> you could also check online to see if anyone knows the pinout, and make your own cables ...
[03:51:03] <ohiopctechDOTcom> yup...
[03:51:15] <SWPadnos> mini-DIN connectors are pretty easy to come by, in 4 or 6-pin varieties anyway
[03:51:16] <ohiopctechDOTcom> i like tearing things apart anyways... ;)
[03:51:31] <ohiopctechDOTcom> they always have lots of cool colored parts inside to look at.. lol
[03:52:13] <ohiopctechDOTcom> but.. a cable would look nicer
[03:52:22] <SWPadnos> heh
[03:52:33] <SWPadnos> on that note, I think I'll get to bed
[03:52:34] <SWPadnos> good night all
[03:53:03] <cradek> wow, probing at 15ipm I get .0005 repeatability
[03:53:19] <cradek> (15ipm is one full step per servo cycle at my scale)
[03:53:25] <jmkasunich> thats from a plain old microswitch?
[03:53:33] <cradek> yes, with a lever on it
[03:53:42] <jmkasunich> nice
[03:53:56] <cradek> screwed to a block of wood in a lathe tool holder
[03:54:11] <jmkasunich> you doing this on the lathe?
[03:54:28] <cradek> no, the lathe tool post (sort of) attaches to the mill table
[03:54:33] <jmkasunich> ah
[03:55:01] <cradek> with two switches you could definitely measure a lathe tool this way
[03:55:09] <cradek> (it would be a bit more intricate)
[03:55:31] <jmkasunich> that would give you the offsets, not the tip radius or angles
[03:55:42] <cradek> right, but those are the easy ones
[03:55:49] <jmkasunich> but I guess the offsets are what changes when you mount the tool
[03:56:37] <cradek> hey I got one of those dual dial calipers for you today
[03:56:45] <jmkasunich> ?
[03:56:46] <cradek> so don't order one
[03:56:52] <jmkasunich> metric english?
[03:56:53] <cradek> you said you wanted one...?
[03:56:53] <cradek> yes
[03:57:04] <jmkasunich> are you sure that was me?
[03:57:07] <cradek> yes
[03:57:16] <jmkasunich> if you say so ;-)
[03:57:18] <cradek> haha
[03:57:20] <jmkasunich> sounds nice anyway
[03:57:23] <cradek> well it's yours whether you want it or not
[03:57:33] <jmkasunich> was it expensive?
[03:57:34] <cradek> it's the one with two needles and two scales on the same dial
[03:57:45] <cradek> no, it's chinese
[03:57:48] <jmkasunich> lol
[03:58:00] <jmkasunich> thanks
[03:58:08] <cradek> welcome
[03:58:17] <cradek> it would be better if you'd remembered you wanted it :-)
[03:58:17] <jmkasunich> I forgot all about that conversation... but its coming back to me now
[03:58:55] <jmkasunich> my mitutoyo has mm graduations at the top of the beam, but nothing on the dial, so its good to about a half-mm or so
[03:59:22] <jmkasunich> gonna bring it to fest?
[03:59:24] <cradek> yes
[03:59:31] <jmkasunich> cool
[03:59:43] <cradek> I have an inch mit. somewhere but I never use it - this dual is very convenient
[04:00:03] <cradek> and (don't roll your eyes) seems to work just as well
[04:00:24] <jmkasunich> if accuract _really_ counts, I don't use calipers anyway
[04:00:32] <cradek> right
[04:00:32] <jmkasunich> cy
[04:00:49] <cradek> and any chinese calipers can tell you the nearest .001
[04:01:06] <cradek> well maybe not any :-P
[04:01:28] <cradek> I've seen some made of plastic with a needle that goes around once an inch
[04:01:53] <jmkasunich> and wobbles
[04:03:07] <ohiopctechDOTcom> what about having emc do some simple radius guessing by stabbing the lathe tool between the two switches until it gets the radius right?
[04:03:28] <jmkasunich> lots of poking and stabbing going on tonight
[04:03:34] <jmkasunich> (and brick throwing)
[04:03:41] <jmkasunich> dangerous in here
[04:03:50] <ohiopctechDOTcom> * ohiopctechDOTcom ducks...AGAIN!
[04:04:06] <jmkasunich> and gets poked in the toes instead
[04:04:30] <jmkasunich> (got your steel toed shoes on?)
[04:05:08] <ohiopctechDOTcom> i have a full medevil amor suit on
[04:05:18] <ohiopctechDOTcom> i always wear it when i am around cnc machines
[04:05:48] <ohiopctechDOTcom> i use the joust to hit the e-stop when needed
[04:05:58] <jmkasunich> good idea
[04:06:02] <jmkasunich> that way you can stand back
[04:06:08] <ohiopctechDOTcom> yip
[04:06:28] <ohiopctechDOTcom> no more chips in my eye!
[04:07:31] <jmkasunich> chips in the beard is annoying too
[04:07:42] <ohiopctechDOTcom> i actually had to have the emergency room dig a chip that melted to my eyeball once at work... went behind my saftey goggles
[04:07:49] <jmkasunich> ouch
[04:08:29] <ohiopctechDOTcom> they clamped my head in this contraption... and used a magnifying glass and a hypodermic needle
[04:08:41] <jmkasunich> cringe
[04:08:45] <ohiopctechDOTcom> the doc told me not to move or i would be blind...
[04:08:48] <ohiopctechDOTcom> yeah!
[04:09:20] <ohiopctechDOTcom> i even wear goggles when i play with this toy cnc at home now
[04:09:39] <jmkasunich> I've worn glasses almost all my life
[04:09:42] <jmkasunich> thats good and bad
[04:09:53] <jmkasunich> good, cause it means I always have _some_ protection
[04:09:53] <ohiopctechDOTcom> the cnc i can carry in my arms.. will still hurt you!
[04:10:18] <jmkasunich> bad, because it makes me less likely to put on proper goggles or safety glasses with side shields
[04:10:21] <cradek> jmkasunich: same here exactly
[04:11:09] <CIA-8> 03cradek 07TRUNK * 10emc2/nc_files/tool-length-probe.ngc: mention a little gotcha
[04:12:01] <cradek> jmkasunich: are your glasses at least polycarbonate?
[04:12:07] <jmkasunich> they're plastic
[04:12:11] <jmkasunich> not sure what plastic
[04:12:43] <cradek> polycarb is very shatter proof - too bad I can't see worth a damn with it
[04:13:17] <ohiopctechDOTcom> ha.. i got **cam doing this fancy hot dog loop when i goes to the next roughing step to clean up corners in the toolpath... it's fun to watch
[04:13:41] <cradek> what cam do you have?
[04:13:48] <ohiopctechDOTcom> mastercam...
[04:13:55] <ohiopctechDOTcom> and artcam...
[04:14:03] <ohiopctechDOTcom> but i haven't used artcam much at all
[04:14:07] <ohiopctechDOTcom> like only a few hours
[04:14:26] <ohiopctechDOTcom> and it's not mine really
[04:14:26] <cradek> I wish one of those big guys supported linux
[04:14:38] <ohiopctechDOTcom> i use it on a friends computer when i get the chance to get over there
[04:14:44] <cradek> ah
[04:14:49] <ohiopctechDOTcom> artcam
[04:15:11] <ohiopctechDOTcom> i have like uh.. student copy? of mastercam.. i'm not sure how you would say that in french...
[04:16:32] <cradek> I have a student version of autocad - if I was a student again, I might buy more software
[04:16:32] <ohiopctechDOTcom> this place i used to work at... i used mastercam.. and they let me put it on my home computer to do work.. and never told me i had to take it off
[04:16:51] <cradek> eek
[04:17:14] <cradek> if they loaned you a company car would you think you'd need to return that, even if they forgot?
[04:17:15] <ohiopctechDOTcom> shh... don't tell anyone esides the whole internet that i jsut mentioned it too
[04:17:37] <ohiopctechDOTcom> well.. if they never asked for it back...
[04:18:15] <ohiopctechDOTcom> i'm sure one day it;ll stop working and i'll buy my own copy
[04:18:27] <ohiopctechDOTcom> because it is the shit
[04:19:28] <ohiopctechDOTcom> idon't think they are missing the dongle.. the guy was loaded
[04:19:39] <ohiopctechDOTcom> and i still talk to them sometimes
[04:20:22] <eric_u> note to self: don't lend chron!c anything
[04:20:49] <ohiopctechDOTcom> geesh jsut ask for it back!
[04:21:07] <jmkasunich> don't lend and then forget who you lent it to
[04:21:13] <jmkasunich> (that happens)
[04:21:31] <ohiopctechDOTcom> maybe that's what happend lol
[04:21:34] <ohiopctechDOTcom> but...
[04:21:38] <cradek> "I knew I used to have a ..."
[04:21:48] <ohiopctechDOTcom> if i didn't have mastercam, there is a few good cheaper
[04:21:50] <eric_u> it's his dad anyway
[04:21:56] <ohiopctechDOTcom> like bobcad i have heard good things about
[04:23:15] <eric_u> if you can't forget to return things to your family, who can you forget to return things to?
[04:23:17] <ohiopctechDOTcom> i was actually thinking of trying the thing i found on your page cradek... i thnk it was
[04:23:21] <ohiopctechDOTcom> for autocad...
[04:23:54] <ohiopctechDOTcom> putting different operations on layers..
[04:25:48] <cradek> yeah it works pretty well, but is very simple - 2.5D only
[04:27:35] <ohiopctechDOTcom> oh it doesn't do z g-codes?
[04:27:46] <cradek> yes it does
[04:27:56] <cradek> 2.5D means ...
[04:27:58] <cradek> hard to explain
[04:28:10] <cradek> either XY moves to cut a shape, or Z moves, never both at the same time
[04:28:35] <ohiopctechDOTcom> i ran a mill they called 2.5d and i just had to set z by had when the control told me to (when i programmed it to)
[04:28:40] <ohiopctechDOTcom> ohh
[04:28:52] <ohiopctechDOTcom> ok.. no xz or yz arcs
[04:29:03] <cradek> ok think of the things you could do with that mill - same idea
[04:29:06] <toastydeath> i'm more familiar with ohiopctechdotcom'S DEFINITION
[04:29:07] <toastydeath> er
[04:29:09] <toastydeath> definition
[04:29:20] <jmkasunich> I would call that 2D
[04:29:24] <toastydeath> unless a mill doesn't support g17/18/19
[04:29:28] <jmkasunich> if Z is completely manual
[04:29:40] <cradek> I would call that a pain in the neck
[04:29:44] <jmkasunich> that too
[04:29:52] <toastydeath> it is
[04:29:53] <ohiopctechDOTcom> it was a prototrack M2
[04:30:18] <ohiopctechDOTcom> conversational.. but i used mastercam to program it.. worked liek a champ, loaded files from a floppy.
[04:30:53] <ohiopctechDOTcom> i used the standard something-trak post and edited a few lines and it ran
[04:30:57] <cradek> http://www.shopbottools.com/3-d_work_v2.htm
[04:31:13] <cradek> second google hit for "2.5D mill" agrees with my definition
[04:31:31] <cradek> some nice pictures that help explain it too
[04:31:44] <ohiopctechDOTcom> i'd say they are both right.. depending on the machine
[04:32:24] <ohiopctechDOTcom> or they were just trying to sell some outdated machines by calling it 2.5 instead of 2
[04:32:48] <ohiopctechDOTcom> the z was linked to the control as far as dro functions.. but no motor...
[04:33:17] <ohiopctechDOTcom> i think that's what they were refering to as the .5
[04:44:25] <ohiopctechDOTcom> * ohiopctechDOTcom is rebooting to ubuntu...
[04:59:28] <Jymmm> I just bought an OBD II reader... Nwow trying to find out if I can connect it to a serial port.
[05:01:45] <ds2> Jymmm: the HF one?
[05:02:13] <Jymmm> yeah
[05:03:46] <eric_u> gotta link to that unit?
[05:05:04] <ds2> have you tried pulling a code yet?
[05:05:05] <Jymmm> search hf for "OBD"
[05:05:10] <ohiopctechDOTcom> wouldn't it be nice iffn when this mastercam/crossover office installer finishes.. that mastercam will actually run right in ubuntu?
[05:05:12] <Jymmm> yeah,
[05:05:20] <ds2> Hmmm
[05:05:34] <ohiopctechDOTcom> **it's installing anyways
[05:05:39] <ds2> I bought their reader once and returned it the same day cuz it couldn't pull a code
[05:05:56] <ohiopctechDOTcom> there is different obd protocols
[05:06:06] <Jymmm> what ohiopctechDOTcom said.
[05:06:20] <ds2> *nod* they claim to do "imports" which is non CAN ISO
[05:12:15] <Jymmm> Hey! Threre's an 8bit uC inside, and I see a data header.
[05:20:22] <ohiopctechDOTcom> ... setup ended with an error on xover office mcam install... trying wine now
[05:20:34] <ohiopctechDOTcom> photoshop runs with xover office
[05:23:42] <toastydeath> do you have the cracked version of mcam
[05:24:06] <ohiopctechDOTcom> i wish then i wouldn't need this stupid dongle to work
[05:24:15] <toastydeath> you may want to download it and try
[05:24:18] <toastydeath> if it doesn't work
[05:28:16] <toastydeath> ooh
[05:28:21] <toastydeath> alternatively, there's a dongle-only crack
[05:28:31] <cradek> ok guys, take this conversation somewhere else
[05:28:34] <toastydeath> so if you can find a valid dongle crack, that may work for you
[05:28:39] <toastydeath> huh?
[05:30:54] <ds2> heh
[05:31:22] <ds2> are SHCS's always grade 8? (thinking of modifying one)
[05:31:51] <ohiopctechDOTcom> there is other grades
[05:32:07] <ohiopctechDOTcom> like cheap one that break when you tighten them
[05:32:11] <ohiopctechDOTcom> ones*
[05:32:27] <ohiopctechDOTcom> i dunno what grade they are..
[05:32:28] <ds2> so you are saying I need to break a few bits to find out?
[05:32:46] <toastydeath> or buy from a reputable seller
[05:32:47] <ohiopctechDOTcom> grade 8 screws are easy to turn or mill/drill
[05:32:58] <ohiopctechDOTcom> i hollow them out all the time for stuff
[05:33:00] <ds2> thought grade 8 is not machineable?
[05:33:03] <Jymmm> Thre *IS* a header... looks like it could be ISP or SPI
[05:33:16] <toastydeath> anything's machinable these days
[05:33:25] <ds2> conventional, HSS, machineable
[05:33:27] <ohiopctechDOTcom> i drill them with regular HSS drill bits
[05:33:32] <ds2> okie
[05:33:35] <ohiopctechDOTcom> right through the allen head
[05:33:46] <ohiopctechDOTcom> though i do it slow
[05:33:55] <ohiopctechDOTcom> and use oil!
[05:34:06] <ds2> need to make myself some security screws...probally going to add a stud to the middle of the hex
[05:34:20] <ohiopctechDOTcom> i took apart thins pc of equip the other night...
[05:34:43] <ohiopctechDOTcom> they screwed the case together.. and then milled the heads off!
[05:34:52] <toastydeath> nice
[05:36:12] <ohiopctechDOTcom> i just beat it with a hammer... worked liek a charm
[05:36:33] <ohiopctechDOTcom> the stepper motors inside.. came out with no scars...
[05:36:41] <ohiopctechDOTcom> two matched steppers...
[05:47:02] <ohiopctechDOTcom> hmm who wants to go dumpster diving!
[05:47:19] <ohiopctechDOTcom> i'm sure we can find some kinda parts for a cnc!
[05:47:26] <ohiopctechDOTcom> i do all the time ;)
[06:12:24] <Jymmm> 89C53RC

[06:46:15] <toastydeath> jymm1:
[08:02:50] <robin_sz> ohiopctechDOTcom, if its a Hasp dongle, there are various utilities out there that will let you replace the dongle driver with a fake driver, you put your dongle in, scan it, lock the dongle in a safe someplace, and then run the fake driver with the scanned data ... works a treat. Handy in say, educational establishments where students are prone to making off with the dongles.
[08:17:02] <Jymmm> I hate when I can't find a datasheet in english!
[08:17:55] <Jymmm> Anyone heard of "STC" before? http://www.114ic.com/company/showpic.asp?id=8173
[08:20:22] <ohiopctechDOTcom> engrish
[08:21:22] <ohiopctechDOTcom> i didn't find anything dumpster diving tonight :( it was cold n wet n windy i didn't stay out long
[08:23:34] <ohiopctechDOTcom> u wanna hear about slow installs... well... try xp pro from a cd under vmware on ubuntu while you are running 4 irc windows and firefox with like 3 tabs
[08:28:51] <anonimasu> ohiopctechDOTcom: nice
[08:28:56] <anonimasu> ohiopctechDOTcom: im looking for a good post
[08:29:05] <ohiopctechDOTcom> mpfan
[08:29:12] <anonimasu> that dosent work too well
[08:29:19] <ohiopctechDOTcom> delete the first 4 lines after it post i think
[08:29:19] <anonimasu> it removes lines after a drill cycle
[08:29:40] <ohiopctechDOTcom> after the % up till the end of the tool def's in parenthesis
[08:30:05] <ohiopctechDOTcom> do the drill cycle last?
[08:30:05] <anonimasu> yeah I know but what to do about the drill cycle and the wrong code it spits out there?
[08:30:10] <anonimasu> heh..
[08:30:17] <ohiopctechDOTcom> what vers?
[08:30:19] <anonimasu> now that's a great solution.
[08:30:23] <ohiopctechDOTcom> i only use v9 for posting
[08:30:26] <anonimasu> v9
[08:30:37] <ohiopctechDOTcom> yeah mpfan
[08:30:50] <anonimasu> does your post do that too?
[08:31:16] <ohiopctechDOTcom> i only post 1 op per prog
[08:31:23] <ohiopctechDOTcom> er 1 tool per prog...
[08:31:29] <ohiopctechDOTcom> both*
[08:31:36] <ohiopctechDOTcom> 1 tool or one op
[08:31:42] <anonimasu> why?
[08:31:46] <ohiopctechDOTcom> in cash i need to run jsut part over again
[08:31:57] <ohiopctechDOTcom> geez typo
[08:32:15] <ohiopctechDOTcom> in case i need to run just part of the part over again...
[08:32:26] <ohiopctechDOTcom> like a spring pass on a pocket or something
[08:32:54] <anonimasu> well that's practical for one off stuff what if you want to make a whole part completed in one run?=
[08:32:55] <ohiopctechDOTcom> part-1.nc... part-2.nc... part-3.nc...etc.
[08:33:17] <ohiopctechDOTcom> if you wanna do it all at once... copy n paste the programs together
[08:33:22] <anonimasu> * anonimasu sighs
[08:33:25] <ohiopctechDOTcom> and delete the percents
[08:33:40] <anonimasu> that's probably the worst solution I've ever heard sorry..
[08:33:46] <ohiopctechDOTcom> and maybe m1 or whatever is end of program
[08:33:55] <ohiopctechDOTcom> it's cake
[08:34:15] <anonimasu> it's a pain to have to hand edit every prog to get it to run or edit at all.
[08:34:18] <ohiopctechDOTcom> and it allows me to touch off all my tools as i use them because i don't have solid hoders
[08:34:48] <ohiopctechDOTcom> do it once or twice it becomes a click click save kinda thing
[08:35:42] <ohiopctechDOTcom> use shortcut keys like "ctrl-x, ctrl-v, ctrl-c, ctrl-s"
[08:36:04] <anonimasu> ohiopctechDOTcom: that's too much work.
[08:36:18] <ohiopctechDOTcom> "alt-f, s... alt-f,O"
[08:36:36] <ohiopctechDOTcom> nothing good is free or easy
[08:36:44] <ohiopctechDOTcom> one or the other **
[08:37:05] <ohiopctechDOTcom> maybe i should phrase it free and or easy
[08:39:10] <ohiopctechDOTcom> there is other solutions i am sure.. that's how i do it. i edit on my fast windows box.. so loading times and stuff aren't bad at all for big g-code files.. snip 4 lines and save then run it on the emcbox
[08:40:24] <ohiopctechDOTcom> sometimes re-ordering your operations changes the way the file posts
[08:40:27] <ohiopctechDOTcom> ;)
[08:43:53] <ohiopctechDOTcom> vmware/xp on ubuntu install is done.. total install time 1hr 10min
[08:47:14] <Jymmm> not much slower than directly, actually.
[08:48:10] <ohiopctechDOTcom> not so much... i usually clock about 45 mins if i stay on top of all the silly q's it asks
[08:48:38] <ohiopctechDOTcom> if.. you copy the cd to the hd first.. installs go a lot quicker
[08:48:54] <ohiopctechDOTcom> maybe down to 25-30 mins
[08:52:16] <CIA-8> 03petev 07TRUNK * 10emc2/src/hal/components/boss_plc.c:
[08:52:16] <CIA-8> -Made export names match comments.
[08:52:16] <CIA-8> -Cleaned up un-needed pre-processor directives.
[08:52:16] <CIA-8> -Cleaned up naming.
[09:46:51] <Jymmm> Have you guys seen this? http://www.geckodrive.com/photos/How_the_G203V_gets_the_most_from_your_motor.pdf
[09:48:25] <anonimasu> yep
[09:49:13] <ohiopctechDOTcom> my wireless mouse died.. i'm going to bed.. muahahaha g'night/mornin
[09:50:12] <Jymmm> anonimasu: I don't get why Mariss doens't have a chart, it makes it confusing.
[09:51:24] <anonimasu> chart?
[09:51:53] <Jymmm> anonimasu: Ok, so what makes the 203v different from the rest (other than the blow up proof stuff)
[09:52:01] <anonimasu> it's FPGA based..
[09:52:14] <anonimasu> so he can fit much more sophisticated logic in there..
[09:52:45] <Jymmm> anonimasu: So, what are 210 and 212 more expensive?
[09:53:09] <anonimasu> no..
[09:53:20] <anonimasu> $148 for a g210
[09:53:27] <Jymmm> 203v = $147
[09:53:33] <anonimasu> and $147 for the g302v
[09:53:42] <Jymmm> 210 = $148
[09:53:51] <anonimasu> yeah..
[09:53:59] <Jymmm> 212 = $168
[09:54:01] <anonimasu> but g210 is a g901/902
[09:54:05] <anonimasu> and a g202..
[09:54:13] <anonimasu> step multiplier..
[09:54:18] <anonimasu> g901 that is..
[09:54:25] <anonimasu> $39
[09:55:31] <Jymmm> so what, have emc send out 1600 instead of 16000 pulses?
[09:55:34] <anonimasu> yeah
[09:55:52] <Jymmm> what am I loosing by doing that, resolution?
[09:55:55] <anonimasu> yep
[09:56:04] <anonimasu> and you will gain top speed..
[09:57:11] <Jymmm> you think the 203 is worth it?
[09:57:19] <anonimasu> probably
[09:57:33] <anonimasu> Ive killed a gecko a while back..
[09:57:38] <anonimasu> if it was a 203 it'd have survived.
[09:58:27] <anonimasu> I know the first 203v's were flakey with the overcurrent stuff.. though that's fixed now..
[09:58:51] <Jymmm> Hmmmm, ok.
[09:59:01] <Jymmm> Alright tiem to go home. G'Night!
[09:59:03] <anonimasu> night

[16:29:52] <alex_joni> hi
[16:31:09] <jmkasunich> make up your minds
[16:33:05] <SWPadnos> middle
[17:28:37] <gene> goddammitalltohellanyway! I edited the /etc/hosts file to add my local network names and addresses, and now I'm locked out of sudo, grrrrr
[17:28:51] <gene> can this be fixed?
[17:29:16] <SWPadnos> what do you mean by "locked out of sudo"?
[17:30:12] <gene> gene@shop:/etc$ sudo vim interfaces
[17:30:13] <gene> sudo: unable to lookup shop via gethostbyname()
[17:30:44] <SWPadnos> is this a remote login, or are you local to that machine?
[17:31:16] <alex_joni> I guess /etc/hostname is bogus
[17:31:37] <gene> local login; the hostsfile now is owned by root, and looks like this
[17:31:56] <gene> and only root can change that
[17:32:39] <gene> its not changed, still 'shop'
[17:33:01] <SWPadnos> what's in /etc/hosts?
[17:33:05] <SWPadnos> (I think)
[17:33:20] <gene> localhost
[17:33:20] <gene> # shop
[17:33:21] <gene> router.coyote.den router
[17:33:21] <gene> coyote.coyote.den coyote
[17:33:21] <gene> 192.168,71.4 shop.coyote.den shop
[17:33:35] <alex_joni> ;)
[17:33:47] <alex_joni> try changing , with .
[17:33:56] <alex_joni> and try prrofreading more next time :P
[17:34:10] <SWPadnos> and you may need to leave the commented shop (second line) in there
[17:34:17] <SWPadnos> err - uncommented
[17:34:43] <SWPadnos> foodtime - good luck ;)
[17:34:46] <gene> ahh, but howto fix this? But that will cause a clash, or has in the past
[17:35:20] <alex_joni> 192.168,71.4 shop.coyote.den shop
[17:35:25] <alex_joni> that's the bogus stuff
[17:35:38] <gene> whats the command for a 'single' login? Yes, I see that now.
[17:36:10] <alex_joni> reboot
[17:36:20] <alex_joni> and look in grub for safe mode or something like that
[17:36:32] <gene> ok, bbl
[17:58:51] <Jymmmmmmm> jmkasunich: In your base period spread sheet, what's the purpose of the itme on the bottom, as opposed to having the formulas "internal" to the grid on top?
[17:58:57] <Jymmmmmmm> items
[17:59:13] <Jymmmmmmm> method 1 - 4
[18:01:57] <xemet> hi
[18:02:16] <xemet> is there a HAL component to calculate sin and cos?
[18:02:43] <xemet> input = alpha -> output = sin(alpha)
[18:03:57] <cradek> siggen has sine and cosine outputs, but they are free running
[18:04:15] <xemet> no, I mean to calculate one value
[18:04:24] <cradek> I don't think so
[18:04:36] <xemet> ok, I can do it with comp, right?
[18:04:39] <cradek> sure
[18:06:26] <xemet> great, I'm seeing that in the hal manual there is just an example to do sin and cos
[18:07:56] <xemet> I added in the wiki a link with two videos of a self-built CNC machine of a friend running with EMC2
[18:08:06] <xemet> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Videos
[18:08:34] <xemet> I hope I've done it right.
[18:09:04] <xemet> he will add more videos in the future
[18:09:52] <cradek> which is it?
[18:10:20] <cradek> ah #1 maybe
[18:11:20] <xemet> yes...sorry but I had problem in putting the direct link to the videos because his server ha a restriction and links were not opened properly
[18:11:40] <xemet> so I had to put the link to the page where there are the videos
[18:11:51] <cradek> that's fine! thanks for adding it
[18:12:16] <xemet> I've introduced him to EMC2 and now he loves it!
[18:12:18] <Jymmmmmmm> Hmmm video#1 crashes VLC
[18:12:33] <xemet> what's VLC?
[18:12:47] <xemet> maybe the wmv format is a problem?
[18:12:58] <xemet> I can ask him to save them in another format
[18:13:08] <Jymmmmmmm> different codec maybe
[18:13:40] <Jymmmmmmm> VLC is a av player with built in codecs - no need to install
[18:14:03] <cradek> Selected video codec: [wmv9dmo] vfm: dmo (Windows Media Video 9 DMO)
[18:14:18] <xemet> what's that?
[18:14:25] <cradek> haha look at all the AXIS splash screens :-)
[18:14:26] <Jymmmmmmm> cradek: what player?
[18:14:31] <cradek> mplayer
[18:14:43] <Jymmmmmmm> is that the same as totem?
[18:14:54] <xemet> it was his first milling test
[18:15:16] <cradek> xemet: nice videos
[18:15:37] <xemet> so he used the first thing he found...the axis splash screen, there is a warning at the beginning that says the splash screen is not intended for real milling...
[18:15:49] <xemet> but it seems to work :)
[18:16:03] <cradek> yes it does
[18:16:05] <cradek> cool
[18:16:20] <Jymmmmmmm> pick anbd place machine?
[18:16:54] <xemet> what's a "pick and place machine"?
[18:17:07] <Jymmmmmmm> the first video
[18:18:08] <Jymmmmmmm> which # is the ones yu uploaded the link to?
[18:18:13] <xemet> the first video is a test with a pen to see if everything was right
[18:18:15] <Jymmmmmmm> Im looking at #8
[18:18:22] <xemet> no, the #1
[18:18:30] <Jymmmmmmm> gotcha
[18:18:36] <xemet> carlo minotti
[18:19:26] <xemet> ah, I can't see the #8 videos in windows player...anyone knows what codec they are?
[18:20:05] <Jymmmmmmm> they played in WMP
[18:20:13] <xemet> ah...I've videos of my milling toy too...maybe I can add them too
[18:22:23] <xemet> I've added one, could you see if the link works?
[18:23:01] <cradek> yes
[18:23:01] <xemet> damn...the link doesn't works directly on my browser...
[18:23:18] <xemet> I've to copy and paste it in the address bar
[18:23:21] <Jymmmmmmm> goes to some altervista page
[18:23:33] <cradek> works fine here, it's a direct link
[18:24:01] <skunkwork_> works here to - cool. I need to make some videos ;)
[18:24:08] <xemet> yes...I know...it is the altervista server that has limitations on direct links
[18:24:37] <xemet> ok, I add others...if it doesn't works please copy and paste them in the address par...
[18:24:41] <skunkwork_> xemet: I would be covering those ways - fiberglase is a very poor lubricant.
[18:25:47] <Jymmmmmmm> Try zshare.org, up to 100mb
[18:25:53] <Jymmmmmmm> err .net
[18:26:05] <Jymmmmmmm> no signup required
[18:26:27] <Jymmmmmmm> xemet: what are you useing for a spindle?
[18:27:23] <xemet> it is a converted Proxxon MF70
[18:27:51] <xemet> http://www.emc2cnc.altervista.org/index.php?option=com_content&task=view&id=17&Itemid=31&limit=1&limitstart=1
[18:30:35] <Jymmmmmmm> Nope, all those links goto the main website here... must be limited by subnet
[18:31:07] <xemet> and if you copy the link and paste it in the address bar? it works here if I do so
[18:31:49] <gene> finally back with aq valid local address, I've been screwing around editing the /etc/interfaces file and ifconfig down/up for half an hour when I should have been using ifdown and ifup
[18:32:06] <xemet> the above link is for pictures of my machine
[18:32:13] <eric_u> vlc doesn't work worth a hoot on those videos
[18:32:24] <gene> Anyway, now I'm ready to try and make the hal file connect g38.2 to pn 10
[18:32:43] <ohiopctechDOTcom> nice setup xemet
[18:32:50] <Jymmmmmmm> eric_u: on the video link xemet JSUT uploaded it does, the MOV files
[18:35:28] <Jymmmmmmm> 50VDC Ps, does 65V caps sound ok?
[18:35:56] <Jymmmmmmm> 36VAC xfmr
[18:39:52] <xemet> well I go for dinner, see you
[18:40:51] <Jymmmmmmm> I was just watching lerneaen_hydra's lather video looks like a chess piece
[18:41:29] <lerneaen_hydra> Jymmmmmmm: it was more of a test piece
[18:41:38] <lerneaen_hydra> radii, straight lines and stuff
[18:41:42] <Jymmmmmmm> oh, looks like a pawn or bishop
[18:42:05] <ohiopctechDOTcom> isn't the video called chess pawn lathe?
[18:42:27] <Jymmmmmmm> lathe.avi
[18:42:54] <ohiopctechDOTcom> i saw one cutting a brass pawn.. called chess pawn lathe
[18:42:57] <ohiopctechDOTcom> maybe it was on oyutbe
[18:43:01] <ohiopctechDOTcom> youtube
[18:43:20] <lerneaen_hydra> maybe the uploader called it chess pawn becuase of the similarities
[18:43:32] <Jymmmmmmm> * Jymmmmmmm dont do youtube
[18:43:40] <ohiopctechDOTcom> uh why not jymm?
[18:43:50] <Jymmmmmmm> too much bs up there
[18:44:07] <ohiopctechDOTcom> it's how i learned what dr. dre was using to make beats.. by watching old interviews with him in it
[18:44:38] <ohiopctechDOTcom> * and wu-tang clan beats... rza uses an mpc
[18:45:55] <Jymmmmmmm> * Jymmmmmmm random thught of the day... I wish I could figure out an automagical tool changer for mine.
[18:46:25] <Jymmmmmmm> oh that reminds me, need to pull outth ebox
[18:46:38] <ohiopctechDOTcom> with those endmills that have threds on the shank.. i think it would be easy to do an ATC
[18:46:51] <Jymmmmmmm> I use a router spindle
[18:47:17] <ohiopctechDOTcom> oh...
[18:47:49] <ohiopctechDOTcom> i got a call today that my 24"x48" table base will be done next weekend... it's going to have a laminate table!
[18:47:57] <ohiopctechDOTcom> countertop laminate*
[18:48:25] <ohiopctechDOTcom> and it'll be sturdy enougth that i can jump on the table while it's cutting and not disturb the part in progress!
[18:49:19] <ohiopctechDOTcom> anyways.. i am going to use a trim router for it...
[18:50:04] <gene> now that's sturdy! g38.2 works here by golly, now to write a program to use it.
[18:50:33] <gene> caffiene fetch time, brb
[18:52:01] <Jymmmmmmm> gene: share bitch! quit teasing us all
[18:54:16] <ohiopctechDOTcom> hmm now that i got vmware/xp-pro working... i should never need to leave ubuntu!
[18:54:34] <Jymmmmmmm> For those that asked yesterday, this is the code reader I bought: http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=94169 When I cracked open the connector there is no electronics in it. When I cracked open the case, There is an 8bit micrcontroller, another chip I can't identify, and a 3pin header with: GND, Tx, Rx
[18:54:56] <ohiopctechDOTcom> thats serial!
[18:55:11] <ohiopctechDOTcom> now to decihper the protocol
[18:55:15] <Jymmmmmmm> The uC is made by STS, but I can't find a mfg website for them.
[18:55:32] <Jymmmmmmm> The uC desc says it does ISP
[18:55:39] <robin_sz> bought that PSU yet?
[18:55:50] <Jymmmmmmm> but the only datasheet I can find is in chinese.
[18:55:55] <ohiopctechDOTcom> have you tried, looking at the data raw through serial?
[18:56:23] <gene> easy, make a copy of the link to Dean Hedins little two pieces of brass and an opto-interrupter, hook the iR led up to the xylotex 5 volt linr thru a 200 ohm resistor
[18:56:33] <Jymmmmmmm> robin_sz: No, but I found a 36VAC @ 7A xmfr for $65 and 17000uF@65V caps for $15
[18:57:06] <Jymmmmmmm> ohiopctechDOTcom: no, I want to read the datasheet first, I'll have one ofthe guys at work translate it.
[18:57:19] <gene> and pull the opto's collector up with a 4320 ohm resistor & feed that to p10 on the xylotex board.
[18:57:20] <robin_sz> (65+15) - 45 = ?
[18:57:21] <ohiopctechDOTcom> oh they know engrish?
[18:57:23] <ohiopctechDOTcom> ;)
[18:57:42] <gene> engrish, fairly well.
[18:57:52] <robin_sz> but a txfrm and caps is a good plan
[18:58:10] <Jymmmmmmm> robin_sz: oh you talking abut that used 48VDC PS?
[18:58:17] <robin_sz> yeah
[18:58:33] <Jymmmmmmm> robin_sz: that guy has bad feedback and never did reply.
[18:58:37] <gene> then go into the standard_pinout.hal file, do away with anything that uses pin 10, and add this line to it:
[19:00:22] <gene> net probe motion.probe-input parport.0.pin-10-in
[19:00:30] <ohiopctechDOTcom> did you wiki it gene? they told me if i had something to put up there do it.. and if they didn't like it they coudl always delete it...
[19:00:58] <ohiopctechDOTcom> btw, the mazak ATC vid is awesome....
[19:02:44] <robin_sz> what was that lathe that turned flats on bar at high speeed?
[19:03:21] <gene> I haven't yet, need to get perms I think.
[19:03:33] <gene> wheres the login prompt?
[19:03:46] <ohiopctechDOTcom> oh the front page...
[19:03:55] <ohiopctechDOTcom> a link called basic steps
[19:04:03] <ohiopctechDOTcom> towards the bottom
[19:04:25] <ohiopctechDOTcom> front page of the wiki
[19:08:02] <ohiopctechDOTcom> guess i'm gonna mow my grass.. (i should put servos on my john deere and cnc the mower... i could write g-code making a map of my yard...
[19:08:28] <ohiopctechDOTcom> what's the g-word for blade down?

[20:50:21] <gene> Humm, apparently have logic problem on while statement. do we still have the m101 print command to lkook at vars?
[20:53:01] <gene> apparently not, I can't get it past the syntax checker
[20:57:27] <gene> why was the m101 command deprecated? do we have somethng even better now?

[21:14:51] <gene> a long way :-(, what do we use for that now?
[21:17:13] <skunkworks_> doesn't (msg,#var) work?

[21:21:37] <gene> msg #var? I'll give that a shot, what happening is that its not using any o100 or o200 call's, falling right by them

[21:40:32] <feoc2> it has its moments
[21:40:36] <gringos> latest I think
[21:40:41] <gringos> non cvs
[21:40:48] <alex_joni> 2.1.4 ?
[21:40:54] <ohiopctechDOTcom> * ohiopctechDOTcom uploading machine vid to youtube now... slowly
[21:40:57] <gringos> yep
[21:41:02] <alex_joni> it would really help if you knew precisely
[21:41:07] <gringos> it does the same thing on both my 64 bit's
[21:41:10] <cradek> cat VERSION
[21:41:12] <gringos> suse 10.2
[21:41:15] <alex_joni> less emc2/VERSION
[21:42:08] <gringos> I really need this to work I have a whole buncha plans
[21:42:14] <feoc2> is the OS's compiled for 64bit ?
[21:42:23] <gringos> ya
[21:42:37] <cradek> do you want to run machinery with it, or just simulate?
[21:42:44] <gringos> either
[21:42:56] <gringos> run machine eventually
[21:42:57] <cradek> did you build a realtime 64 bit kernel?
[21:43:05] <cradek> that's very new territory for RTAI
[21:43:18] <cradek> none of us have used it
[21:43:39] <feoc2> gringos your best bet is to get the live CD from the website and try it out using that
[21:43:52] <gringos> have it I'll burn it and try
[21:44:03] <alex_joni> that's not 64 though
[21:44:14] <feoc2> no its not
[21:44:16] <gringos> so it wont work ?
[21:44:16] <feoc2> but it works :)
[21:44:21] <gringos> hehe
[21:44:32] <alex_joni> it does work.. just in 32 bit mode

[21:51:26] <gringos> I got the cd done burning
[21:51:32] <gringos> I'll tester out and bbl
[21:51:46] <alex_joni> gringos: you can configure the emc2 sources to build locally
[21:51:54] <alex_joni> so you can try them out without installing to /usr/*
[21:52:12] <alex_joni> that way you can compile.. and test, without messing a working install
[21:52:13] <gringos> that command you told me had no effect
[21:52:23] <alex_joni> gringos: you need to run configure before you run make

[21:54:25] <gringos> I bought a set of homade plasma cutter plans off the bay the other day
[21:54:35] <Roguish> hey all. how do i install a usb gamepad to use with emc? right now just the linux portion, not the emc part.
[21:54:55] <cradek> Roguish: insert the plug into a usb port
[21:55:06] <Roguish> clever, been there.
[21:55:19] <cradek> that's the linux part afaik
[21:55:31] <alex_joni> cradek: you need to mess with udev
[21:55:31] <Roguish> is there any way to test it?
[21:55:43] <cradek> oh, ick
[21:55:45] <alex_joni> Roguish: man hal_input will tell you about it
[21:55:53] <cradek> I retract my answer then, sorry
[21:56:26] <alex_joni> http://www.linuxcnc.org/docs/2.1/html/man/man1/hal_input.1.html
[21:56:33] <gringos> how do I run it now ?
[21:56:46] <gringos> run the exe's in bin ?
[21:56:47] <cradek> gringos: applications/cnc/emc2
[21:56:50] <Roguish> ah, so, looking at it. thanks.
[21:56:50] <alex_joni> gringos: scripts/emc
[21:56:58] <ohiopctechDOTcom> my joystick (usb) worked as soon as i plugged it in
[21:57:10] <gringos> sweet it works
[21:57:11] <ohiopctechDOTcom> not the emc part though
[21:57:14] <cradek> oh, not the cd, the build
[21:57:21] <alex_joni> gringos: yay.. is that the 64 bit version?
[21:57:25] <cradek> I can't get any answers right tonight
[21:57:31] <gringos> yes
[21:57:35] <Jymmmmmmm> * Jymmmmmmm hands cradek a beer
[21:57:37] <gringos> all it took was a define null
[21:57:42] <jmk-solo> cradek: it not tonight yet!
[21:57:46] <alex_joni> cradek: we all have days like these
[21:57:52] <alex_joni> 00:51 < jmk-solo> cradek: it not tonight yet!
[21:57:59] <alex_joni> jmk-solo: think again :P

[21:58:19] <cradek> feels later than it is
[21:58:29] <cradek> (getting dark)
[21:58:38] <jmk-solo> nasty weather again?
[21:58:45] <alex_joni> gringos: eek
[21:58:46] <cradek> not so bad, but dark
[21:58:54] <gringos> who here's built a tesla turbine ?
[21:59:10] <alex_joni> gringos: you should check that configure doesn't barf on things it can't find
[21:59:15] <alex_joni> like maybe .. libpth :D
[21:59:44] <Jymmmmmmm> What are they refering to at the bottom in respect to deviation? http://www.u-oplaz.com/table/prism01.htm
[22:00:00] <gringos> brb reboot time
[22:00:39] <Jymmmmmmm> tolerance of the "true" 90 deg?
[22:00:55] <jmk-solo> Jymmmmmmm: that means the light coming out is at 90 degrees to the light going in, even if the prism is rotated slightly
[22:01:31] <jmk-solo> if you used a simple mirror to bend light 90 deg, the mirror must be at exactly 45 degrees, and every 1 deg of mirror movement moves the beam by 2 deg
[22:02:06] <alex_joni> and it only works for 1-few beams
[22:02:30] <alex_joni> and it inverts images..
[22:02:33] <Jymmmmmmm> jmk-solo: so 10S deviation means it cna tolerate higher mistalignment ?
[22:02:38] <jmk-solo> no
[22:02:54] <jmk-solo> a perfect pentaprism will bend light 90.0000000 degrees
[22:03:01] <ohiopctechDOTcom> http://www.youtube.com/ohiopctech <-- my first of many cool cnc vids
[22:03:15] <jmk-solo> one with a 1min deviation is guaranteed to bend it 90 deg +/- 1 minute of arc
[22:03:26] <ohiopctechDOTcom> i need to work on lighting maybe but it's a vid!
[22:03:29] <jmk-solo> (1 min of arc = 1/60 of a degree)
[22:03:43] <Jymmmmmmm> jmk-solo: ok, gotcha TY
[22:03:57] <alex_joni> ohiopctechDOTcom: nice..
[22:04:01] <ohiopctechDOTcom> ty
[22:04:03] <alex_joni> although I see no reference to emc there :P
[22:04:17] <ohiopctechDOTcom> ehh.. in the vid description and keywords
[22:04:38] <Roguish> ohiopcteckDOTcom: how do you know if the joypad works? what tests it? a game or something?
[22:04:40] <ohiopctechDOTcom> i put linux emc emc2 linuxcnc
[22:05:10] <ohiopctechDOTcom> Roguish: there is a pge on the wiki with instructions for testing with hal
[22:05:44] <Jymmmmmmm> jmk-solo: Not that I know crap in respect to optics, but I feel they could be used in CNC applications
[22:05:50] <ohiopctechDOTcom> * ohiopctechDOTcom will try to find it
[22:06:03] <jmkasunich> it looks like the camera is focused at infinity, the background is the only thing sharp
[22:06:06] <Roguish> yes...but i was hoping to get it going in the os first.
[22:06:09] <jmkasunich> is it fixed focus?
[22:06:30] <ohiopctechDOTcom> yeah.. i think i had the camera too close
[22:06:42] <ohiopctechDOTcom> i'll do some better vids once i figure out the capture settings
[22:06:54] <jmkasunich> is there any focus adjustment?
[22:06:56] <ohiopctechDOTcom> it's the first live vid i ever captured other than my security cameras
[22:07:14] <jmkasunich> even my cheap ass webcam has a knurled plastic ring around the lens to focus it
[22:08:57] <alex_joni> good night all
[22:09:07] <Jymmmmmmm> nite
[22:09:16] <mschuhmacher> night
[22:10:59] <mschuhmacher> ohiopctechDOTcom: You could use an old magnifying-glass as a zoom objective
[22:11:04] <alex_joni> this is fun to watch http://www.youtube.com/watch?v=d7szecnTfRI
[22:12:41] <eric_u> nice rabbit
[22:16:56] <CIA-8> 03cradek 07v2_1_branch * 10emc2/VERSION: bump after release
[22:17:27] <alex_joni> yay 2.1.5
[22:18:26] <alex_joni> alex_joni has changed the topic to: Welcome! EMC (Enhanced Machine Controller) is a linux-based opensource CNC control. | Latest release: EMC 2.1.5 | http://www.linuxcnc.org | http://wiki.linuxcnc.org
[22:20:55] <Jymmmmmmm> jmkasunich: Silly question, could halscope be used as a REAL scope?
[22:21:25] <jmkasunich> only if you have some A/D converters supported by HAL, and can live with the rather slow sample rate
[22:21:39] <Jymmmmmmm> slow being 20Khz?
[22:21:42] <jmkasunich> real digital scopes sample at many mega-samples per second
[22:21:42] <alex_joni> jmkasunich: how about soem fast adc's connected to a mesa?
[22:21:44] <jmkasunich> rught
[22:21:46] <jmkasunich> right
[22:22:12] <jmkasunich> you'd still be limited to however fast you can run a HAL thread
[22:22:24] <Jymmmmmmm> okey dokey
[22:22:29] <alex_joni> unless you do some buffering inside the board
[22:22:49] <Jymmmmmmm> Eh, I'll see if I cna win this auction
[22:22:56] <Jymmmmmmm> 20MHz
[22:23:09] <alex_joni> Jymmmmmmm: that sounds more like a scope
[22:23:22] <Jymmmmmmm> Yeah, dual channel
[22:25:53] <Jymmmmmmm> I figure I could start looking at the signals and see what's going on, plus a few other things I've been wanted to paly with.
[22:26:42] <jepler> cradek: thanks for your work on 2.1.5
[22:27:22] <cradek> jepler: welcome
[22:27:39] <ChrisMorley> greetings
[22:28:03] <ChrisMorley> Kinda quite right now?
[22:28:17] <cradek> quiet? not at all
[22:28:32] <cradek> just made the EMC 2.1.5 release
[22:28:55] <jtr> ohiopctechDOTcom: That "Jensen" lathe you posted looks like a Sherline - see http://www.sherline.com/images/4000pic.jpg The extra piece in the foreground is a vertical milling column attachment.
[22:29:00] <ChrisMorley> Yes I see that . just keeps marching on! good good
[22:29:49] <ChrisMorley> I would like to contribute to classicladder soon -just gotta clean up the code a bit
[22:34:29] <ChrisMorley> ahh then the girlfriend come ...gotta go.
[22:40:01] <gringos> any plans on turning emc into a full fledged cad program ?
[22:40:35] <cradek> no
[22:40:52] <cradek> nor a word processor, or anything else other than a machine controller
[22:41:13] <eric_u> spreadsheet?
[22:41:26] <cradek> nope
[22:42:04] <eric_u> I can see a conversational front end, but cad doesn't really make sense
[22:42:35] <gringos> I need a copy of r14
[22:42:42] <gringos> I hear it runs in wine
[22:42:53] <cradek> r14?
[22:43:02] <gringos> revision 14
[22:43:11] <gringos> autocad
[22:43:31] <cradek> a friend bought autocad r12 on ebay not too long ago, but some of the floppies were bad
[22:43:43] <cradek> it's hard to find some of that old software
[22:44:25] <gringos> friend of mine is writing a program called gcam
[22:44:42] <gringos> makes gcode
[22:46:54] <Martin_Lundstrom> Dallur: Are you awake?
[22:47:58] <gringos> http://gcam.js.cx/index.php/Main_Page
[22:51:26] <gringos> has anyone here seen the turbocnc source code ?
[22:51:56] <eric_u> you have to buy it nowadays, correct?
[22:52:03] <gringos> ya :/
[22:52:12] <gringos> 60 usd
[22:52:19] <eric_u> not gonna happen
[22:52:50] <gringos> great program though
[22:53:06] <ohiopctechDOTcom> how's the dxf-import coming along in g-cam?
[22:53:31] <gringos> not too sure
[22:53:47] <ohiopctechDOTcom> if that works.. i will start using it...
[22:54:07] <ohiopctechDOTcom> *gcam that is
[22:54:15] <ohiopctechDOTcom> i was impressed with the interface
[22:54:48] <gringos> Twingy's a great programmer
[22:55:13] <gringos> good with the opengl stuffs
[22:55:14] <ohiopctechDOTcom> from what i saw i agree
[22:56:09] <ohiopctechDOTcom> does anyone ever use a de-compiler to peek at source codes?
[22:56:34] <ohiopctechDOTcom> or do they not work like that? i am clueless on the subject other than i know they exist
[22:57:29] <gringos> they spit out psudo code usually
[22:57:43] <gringos> your better off using a debugger
[22:58:06] <gringos> sometimes
[22:58:39] <gringos> psudo c code is confusing as hell when you dont know whats happening
[22:59:08] <gringos> IDA works good for showing whats going on
[22:59:09] <ohiopctechDOTcom> but, it could be a jumping point for re-wrting the app?
[23:01:36] <Martin_Lundstrom> How do I add support for "logic" HAL:8: ERROR: Can't find module 'logic' in /home/martin/emc2.1.4/rtlib
[23:02:41] <Jymmmmmmm> Martin_Lundstrom: live long and prosper
[23:04:05] <jepler> Martin_Lundstrom: 'logic' is only in TRUNK, not in 2.1.x.
[23:04:06] <Martin_Lundstrom> hmmm
[23:04:16] <Martin_Lundstrom> ok
[23:04:21] <Jymmmmmmm> T1 must be our desired output Vo PLUS the voltage drops across D2 and D4 ( 2 * 0.7V) divided by 1.414
[23:04:38] <Martin_Lundstrom> so what do I do?
[23:04:59] <jepler> yay dinner
[23:05:10] <Jymmmmmmm> jepler: grule?
[23:05:11] <Martin_Lundstrom> make a new cvs thing for trunk!?
[23:05:23] <Martin_Lundstrom> jepler: bon apetit!
[23:06:02] <Jymmmmmmm> In a PS, what is the purpuse of caps to gnd on the primary side of a xfmr?
[23:06:12] <gringos> you guys wana know a secret ?
[23:06:14] <ohiopctechDOTcom> filtering?
[23:06:20] <ohiopctechDOTcom> i love serets!
[23:06:27] <ohiopctechDOTcom> secrets even*
[23:06:27] <Jymmmmmmm> gringos: nah
[23:06:29] <gringos> you can do 3d milling with a plasma cutter if you go really fast
[23:06:34] <Jymmmmmmm> lol
[23:06:37] <ohiopctechDOTcom> lol, gringos
[23:06:59] <ohiopctechDOTcom> you can do it with a swiss army knife if you go really slow
[23:07:21] <Jymmmmmmm> pic http://my.integritynet.com.au/purdic/power1.html
[23:08:46] <gringos> thats a weird fullwave rectifier
[23:09:10] <Jymmmmmmm> I think the pic is just misleading is all
[23:09:35] <Jymmmmmmm> I'm stil trying to figure out the caps on te primary side
[23:09:44] <zelva> hello guys.. can anyone help me? I compile emc2 2.1.4 on linux kernel 2.6.19 with rtai 3.5 and everything went smooth... i can tun emc/script/realtime and no error, but if i run ./emc and choose anyone config, system freeze...
[23:09:54] <gringos> I have 10000 resistors and lots of blank copper pcb board
[23:10:19] <gringos> and no idea what to print
[23:10:23] <Jymmmmmmm> gringos: keep the resistors and just send me some PCB
[23:10:32] <cradek> zelva: I also had that problem. I think there is a problem with 2.6.19. 2.6.17 works fine.
[23:10:44] <Jymmmmmmm> gringos: make some db25 breakout boards
[23:10:45] <gringos> I have a 4'x8' sheet
[23:10:55] <Jymmmmmmm> make a LOT of them
[23:11:41] <zelva> aha thx cradek... i'll try with 2.6.17 right now...
[23:11:42] <gringos> what kind of relay's are good ?
[23:11:51] <Jymmmmmmm> solid state
[23:12:08] <cradek> zelva: somewhere I found a message that said what the problem is, but I can't find it again
[23:12:36] <Jymmmmmmm> gringos: opto 22 seems common
[23:12:37] <zelva> :(
[23:13:06] <ohiopctechDOTcom> wanna sell some pcb stock?
[23:13:15] <ohiopctechDOTcom> i been meaning to buy some
[23:13:18] <gringos> im stuck for an idea on how to make my z head
[23:13:22] <Jymmmmmmm> gringos: http://www.opto22.com/site/pr_cat_g.aspx?qs=1006
[23:13:37] <gringos> I bought 100 skateboard bearings
[23:13:48] <gringos> made 2 beds into one xy table
[23:13:50] <ohiopctechDOTcom> * ohiopctechDOTcom only bought 8 skateboard bearings
[23:13:51] <gringos> bed frame's
[23:14:09] <gringos> this one locks together nicely
[23:14:24] <zelva> funny thing... yesterday i run emc and its works... today nothing... and i can't remember what i do :(
[23:15:27] <gringos> whats the best windows milling program ?
[23:15:32] <gringos> mach3 ?
[23:15:45] <ohiopctechDOTcom> the ubuntu live cd ;)
[23:16:28] <gene> hey people, its working!
[23:16:49] <ohiopctechDOTcom> did you do some uh.. probing?
[23:17:24] <robin_sz> mmm .. probing
[23:18:01] <eric_u> meci or midwest surplus should have pcb stock
[23:18:59] <ohiopctechDOTcom> my first project was going to be a db25 breakout
[23:19:02] <eric_u> actually, gene was talking about his solitaire program
[23:19:05] <ohiopctechDOTcom> was/is
[23:22:05] <robin_sz> I remember a great design for a probe
[23:22:13] <robin_sz> involving ball bearings
[23:23:08] <Martin_Lundstrom> jepler: trunk did it, thanks
[23:23:12] <ohiopctechDOTcom> plans for it are in one of the yahoo cnc group's files
[23:30:16] <robin_sz> http://www.indoor.flyer.co.uk/probe.htm
[23:30:52] <skunkworks> robin_sz: did anonimasu ever get a hold of you? (he was looking for you)
[23:32:57] <robin_sz> mmmnot today
[23:33:31] <skunkworks> so we went to rochester, mn to see the band america. There was a comp usa going out of business - 40%+ off everything. and everything was still too expensive. I thought comp usa priced stuff pretty decent.
[23:35:05] <ohiopctechDOTcom> 40% off prices that they marked up two weeks before
[23:35:13] <skunkworks> exactly
[23:35:49] <eric_u> previously when they did that, they finally sold everything to a business at surplus prices.
[23:36:05] <zelva> i simply cant understand... rtai works fine, realtime works fine but emc freeze :S
[23:36:07] <eric_u> don't know why companies don't do what target does and just keep slashing the price until people buy
[23:36:56] <robin_sz> very poor business strategy
[23:37:12] <ohiopctechDOTcom> compuasa... go DD out back after they close once a week right before they empty the bin... :|
[23:37:25] <ohiopctechDOTcom> compusa*
[23:38:09] <robin_sz> eric_u, assume the part cast say, 100 dollars to make
[23:38:12] <ohiopctechDOTcom> printers, blanks cd's, lcd monitors, ink cartridges
[23:38:55] <robin_sz> eric_u, at a selling point of say $110 I sell 1000 and make 10,000 doallrs
[23:39:27] <eric_u> I'm just saying, if you sell the part for $2, sell it to your customer, not some other company
[23:39:32] <robin_sz> at a selling point of $500 I only sell 20
[23:39:35] <eric_u> this way they are just making people mad
[23:40:05] <robin_sz> I still make $8000 for 1/50th of the effort
[23:40:19] <Martin_Lundstrom> What do I have to do to set up pyVCP? Starting EMC2...
[23:40:18] <Martin_Lundstrom> pyVCP: Creating widgets from thc_vcp.xml ...
[23:40:18] <Martin_Lundstrom> Error constructing spinbox({
[23:41:24] <robin_sz> a high price/low volume business can always drop a little to build volume in tough markets conditions
[23:41:38] <robin_sz> a low price/high volume business doesnt have any place to go
[23:42:01] <eric_u> store is going out of business, company will take a loss, why try to extract max dollars out of it when it is a writedown anyway?
[23:42:27] <robin_sz> maybe they have other stores
[23:42:38] <robin_sz> heres a thing ...
[23:42:50] <robin_sz> I met a guy last week
[23:42:51] <ohiopctechDOTcom> they will jsut ship stock to other usa stores, or compusa does ebay too
[23:43:09] <eric_u> no, they are going to salvage the stock, or that's what they have done before anyway
[23:43:15] <robin_sz> sells pasta to $majorChain
[23:43:29] <eric_u> lowes here did the same thing when they moved their store, they had an auction
[23:43:32] <robin_sz> what do you think his margin is?
[23:43:54] <eric_u> 60%
[23:44:00] <robin_sz> less ...
[23:44:56] <robin_sz> it did have a 6 and a 0 in it ... and a deciml point
[23:45:07] <eric_u> the math is entirely different if the final result is that you are going for a tax writeoff
[23:45:48] <eric_u> compusa is just stretching this whole store closing thing out and spending money when they could move on
[23:46:04] <robin_sz> 0.6%
[23:46:08] <Martin_Lundstrom> How do I build with python?
[23:49:46] <eric_u> the markup at compusa is probably over 100%
[23:50:56] <eric_u> margin considerably less
[23:51:20] <gringos> hey I thought up a new feature
[23:51:45] <gringos> you make the z head touch all 4 corners of your project so you know how level it is
[23:52:15] <gringos> and the machine can adjust
[23:52:55] <gringos> does emc work well with usb to paralell adapters ?
[23:53:04] <skunkworks> gringos: no
[23:53:10] <eric_u> nothing works well with usb to parallel adapters
[23:54:07] <gringos> its the same talk though
[23:54:21] <eric_u> printers work fine
[23:54:25] <zelva> good night to all
[23:54:33] <skunkworks> printers are not real-time devices
[23:54:36] <gringos> oh
[23:55:23] <eric_u> I just wanted to be clear since I said "nothing"
[23:55:25] <gringos> emc looks dam sexy
[23:55:36] <gringos> got it running on my older comp finally
[23:56:03] <gringos> http://www.brusselsprout.org/CAMBAM/screenshots/HeightmapPlugin.png
[23:56:44] <skunkworks> gringos: very nice
[23:59:08] <Martin_Lundstrom> Anyone have experience with pyvpc and initval?
