[00:01:04] <pfred1> the pulse is 5.09 us
[00:01:53] <pfred1> distance between pulses is 100 us
[00:18:01] <pfred1> well that was all very exciting I think I've had enough for now I'll test my BOB out another time
[00:19:16] <GoTschA_> GoTschA_ is now known as GoTschA
[00:27:10] <elmo40> aa-danimal-shop: forming taps do leave a better surface, don't they
[00:28:09] <aa-danimal-shop> yea, much nicer
[00:29:30] <elmo40> especially on those wee ones
[00:29:41] <elmo40> we use them for 4-40UNC holes.
[00:30:12] <elmo40> and the 2-56
[00:30:36] <elmo40> 2-56 is about 2.2mm
[00:30:54] <elmo40> real tiny. I bet it would be easy to strip something like that.

[01:02:29] <MarkusBec> MY real LAZER :)
[01:39:26] <tlab> MarkusBec, how many watts?
[01:40:08] <MarkusBec> 80W
[01:40:44] <tlab> wow how much that set you back?
[01:40:56] <DaViruz> crazy fast rapids
[01:42:01] <MarkusBec> 1200mm/sec cutting
[01:42:15] <MarkusBec> 5000mm/sec engraving
[01:42:33] <MarkusBec> and 20000mm/sec fast positioning
[01:42:41] <tlab> my old job we had a 4.5kW laser
[01:42:52] <MarkusBec> :)
[01:43:14] <tlab> used to fuse metal together 8)
[01:43:26] <MarkusBec> 8)
[01:43:45] <tlab> another line had a 12kW laser
[01:43:49] <MarkusBec> we will cut wood and plastic for models and robots
[01:44:01] <tlab> nice
[01:44:19] <MarkusBec> http://markusbec.deswahnsinns.de/main.php/v/album_1260292830/
[01:45:26] <tlab> was the laser part hard to build?
[01:45:40] <MarkusBec> salfmade diy projekt :)
[01:46:04] <MarkusBec> no
[01:46:40] <MarkusBec> we ask an manufacor in china to send us an set with the powersupply the tube an mirrors
[01:47:15] <tlab> how much $$?
[01:47:26] <MarkusBec> 2000 ?
[01:47:48] <tlab> ouch
[01:49:52] <MarkusBec> http://cgi.ebay.com/Laser-Cutter-Engraving-Machine-CAMFive-80W-Z-Movement_W0QQitemZ180482787394QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item2a059cc842
[01:50:13] <MarkusBec> cheaper than a out of the box product :9
[01:50:23] <tlab> oh I'm sure
[01:51:24] <MarkusBec> we build it with dc servos
[01:51:42] <MarkusBec> 300W continus and 1,5kw peak
[01:52:08] <MarkusBec> with an granitdevices servo controller
[01:55:07] <tlab> so you have to have tanks of co2 n2 and he then?
[01:55:24] <MarkusBec> no
[01:55:46] <MarkusBec> the tube have a lifetime filling
[01:55:58] <MarkusBec> 4000h with 100%
[01:56:07] <MarkusBec> after it you need a new tube
[01:56:12] <tlab> ah
[02:12:32] <MarkusBec> MarkusBec is now known as MarkusBec_away
[04:53:49] <elmo_cnc> what is this error?
[04:54:04] <elmo_cnc> Linear move on Line 3 would exceed joint 2's positive limit
[04:54:17] <elmo_cnc> i dont understand. i am moving 2"
[05:13:52] <aa-danimal-shop> your 2 inches is exceeding your soft limits
[05:14:16] <aa-danimal-shop> do you have home switches?
[05:17:12] <aa-danimal-shop> elmo_cnc, if your programed move isnt exceeding your machine's mechanical limitations, you need to change the MIN_LIMIT and MAX_LIMIT in your ini file
[05:18:24] <aa-danimal-shop> or your work offset is wrong
[05:18:39] <aa-danimal-shop> i'm guessing it's a lathe?
[05:19:59] <aa-danimal-shop> joint 2 is the z axis on a mill.... kinda weird that you'd be exceeding the positive z limit unless you're not using home switches
[05:20:19] <aa-danimal-shop> i'm going to bed, but good luck
[05:26:34] <Guest425> wie richtet man einen Bildschirm ein? Ich habe ein Touchscreen von ELO welchen er nicht kennt und gibt desshalb nur 600x800 Pixel aus.
[05:35:31] <elmo_cnc> aa-danimal-shop: thanks, that was it. i set my home positions on the wrong side ;) When it loaded a file the workpiece zero was off of the machine table. (in the display).
[05:56:46] <elmo_cnc> some files http://mydxf.blogspot.com

[06:07:26] <elmo_cnc> yes, looks like a square hole... what of it? ;)
[06:12:13] <skunkworks> it wasn't there before!

[09:30:52] <Valen> just testing
[09:31:43] <archivist> fail :)
[09:33:03] <Valen> 2 beers and a lightweight = made of win ;->
[09:33:06] <Valen> cheap win at that
[09:33:25] <Valen> 2 beers and i'm any hot skinny blondes
[09:36:44] <Valen> 3 beers and i'll settle for a brunette ;->

[11:35:07] <awallin_> some machining yesterday: http://www.youtube.com/jmi80#p/a/u/0/PgpWrl35I4Y
[11:35:35] <awallin_> madness really, DIY making parts that cost <2eur to buy.... :)
[11:36:53] <archivist> music is a bit ....
[11:40:33] <JT-Dev> i don't have speakers on this machine
[11:40:52] <JT-Dev> awallin_: what software generated the g-code
[11:43:49] <JT-Dev> nice parts
[11:48:02] <awallin_> no speakers here either...
[11:48:27] <awallin_> JT-Dev: using an old version of surfcam (while we wait for heekscam to become awesomer...)
[11:49:14] <JT-Dev> kinda looked liked the output from my OneCNC cutting lots of air LOL
[11:49:26] <archivist> I though your dropcutter was in action for a moment :)
[11:49:48] <JT-Dev> except yours didn't jump up and down like OneCNC likes to do
[11:50:25] <archivist> although the clearance in Z was the slow way
[11:50:25] <awallin_> the drop-cutter will locate the cutter on the surface, what you do in between is your problem...
[12:16:13] <sealive> hi to the USA
[12:16:37] <sealive> can i take a config of the mashine from one to another Computer
[12:16:39] <JT-Dev> some of us are awake :)
[12:16:57] <JT-Dev> yes just copy the whole config directory
[12:17:11] <sealive> we here in the EU have lost 1Houre this night
[12:17:35] <sealive> changing from MEZ to MESZ
[12:19:30] <sealive> and the russians(the World) did this night loose a hole timezone
[12:19:51] <sealive> CNN may broadcast it
[12:20:04] <sealive> trouout the day
[12:27:43] <sealive> i just set up the 4th PC with EMC2 this one is a bigger pone then the other with 1,2Ghz 512MB ram running Xbuntu hardy shoudt i upgrade the emc2 from 2.3.5 that the SH installt or leave that
[12:30:27] <Valen> (23:28:56) Valen: we CnCed up some aliminium heads for those squese clamps
[12:30:27] <Valen> (23:29:09) Valen: the ones you do up with a ratchet style arrangement
[12:30:27] <Valen> (23:29:14) Valen: the plastic ones blew up
[12:30:27] <Valen> (23:29:37) Valen: whats your spindle speed?
[12:30:27] <Valen> (23:29:46) Valen: awallin
[14:50:07] <Guest344> Test
[14:50:11] <Guest344> Hello
[14:50:50] <Guest344> Anyone here?
[14:51:49] <MOGLI> ask the question
[14:53:18] <Guest344> Looking for some assistance getting EMC2 to work with a Via EPIA 800 Mini-ITX mobo. I was able to get it to run from the live CD, but when I add a hard-drive to the machine, the live CD won't load. The HD works, and I've verified I can boot from the HD (old Red-Hat install).
[14:54:54] <Guest344> BTW, the live CD starts to load, but when it gets to the GUI, things get really really slow (I can move the mouse, and the pointer moves after 1-2 minutes for example). 14 hours later, it still has not loaded, and I can heard the CD rom drive moving occassionally.
[14:58:11] <cradek> but without the hard disk the same live cd boots and runs fine?
[15:00:53] <cradek> the slow failure to boot is usually the result of not enough ram, but I can't explain the hard disk addition causing that.
[15:02:47] <SWPadnos> I wonder if less stuff gets loaded when there's no disk present (at least drivers and filesystems wouldn't be needed, maybe there's other stuff too)
[15:03:04] <SWPadnos> but that doesn't sound like "the" problem
[15:04:07] <steverob> Good morning guys
[15:06:22] <SWPadnos> hi
[15:08:54] <steverob> Question: I need to move my tabletop mill to the garage but, don't want to move my computer. I am trying to figure out the easiest way to operate the mill remotely.
[15:09:41] <SWPadnos> you have to have a computer attached to the mill, even if you have a remote GUI
[15:09:50] <SWPadnos> the remote GUI would run on a second computer
[15:13:18] <steverob> Yep... I would run a parallel cable from the computer in the house to the machine in the garage. I don't have a second computer to put in the garage so, I was thinking of using a dumb terminal and controlling the session that way.
[15:13:28] <SWPadnos> nope
[15:13:57] <SWPadnos> at least, I don't think so, if I understand you correctly
[15:14:02] <aa-danimal-shop> morning
[15:14:17] <steverob> No? Isn't there a command line interface to emc?
[15:14:21] <aa-danimal-shop> SWPadnos, you know a bit about cameras, right?
[15:14:27] <Guest344> Yes, live CD boots up fine w/o HD. I've verified that the HD and CD are not conflicting, as I can boot from the HD.
[15:14:44] <SWPadnos> there are a couple of text terminal based user interfaces (xemc and yemc, plus emcrsh, a telnet-like thing)
[15:14:47] <SWPadnos> aa-danimal-shop, yes
[15:15:17] <aa-danimal-shop> is this an ok camera for a beginner, and a good deal? http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=390173608052
[15:15:21] <SWPadnos> what signals would you expect the parallel cable from the house to the garage to carry?
[15:15:28] <aa-danimal-shop> guess it's kinda late to be asking, but..
[15:16:03] <steverob> Just the step, direction, home, and spindle signals.
[15:16:38] <SWPadnos> you'll need to make a very expensive shielded cable, and have a very very good breakout board
[15:16:53] <SWPadnos> aa-danimal-shop, I don't know that camera specifically, but it does look like a good deal
[15:17:04] <SWPadnos> I think jmkasunich may have a similar camera
[15:17:28] <steverob> The distance is short enough so that might not be a "big" problem.
[15:17:40] <MOGLI> hey anyone have idea/hal file so i can use Encoder with Pluto-P Stepper??
[15:18:08] <aa-danimal-shop> ah, ok, thanks. i was originally looking for a nikon or cannon, but they were a bit out of my price range unless i wanted one from like 2003
[15:18:14] <MOGLI> or is it possible to use 2 hardware in one HAL FILE .. i.e. Step/Dir from Pluto and Encoder in Parallal PORT
[15:18:17] <SWPadnos> if you can do it with a 2-6 foot cable, then it's no different than having the computer sitting next to the machine (it is, but the cable goes through the wall :) )
[15:19:07] <SWPadnos> aa-danimal-shop, you'd be surprised. A Nikon D1 (4 MP, I think) takes phenomenal photos
[15:19:28] <steverob> It would be slightly longer than that but, not much. The problem is I'd have to run back and forth from the garage to house to run the machine.
[15:19:57] <SWPadnos> I don't think so
[15:20:02] <steverob> I was hoping I could use a dumb terminal and run the mill from the command line.
[15:20:29] <SWPadnos> if you can log into the computer from a dumb terminal, then you can do that using xemc/yemc/emcrsh
[15:20:35] <aa-danimal-shop> hmm... well all i really need this one for is for taking product pictures. The extra lens was a bonus
[15:21:03] <SWPadnos> steverob, I'm confused as to where you're thinking all these pieces go
[15:21:18] <SWPadnos> you have the machine, the PC, and a dumb terminal. which parts are where?
[15:22:13] <aa-danimal-shop> <====terminally dumb
[15:22:20] <SWPadnos> shhh
[15:22:23] <SWPadnos> :)
[15:22:39] <steverob> my computer that's running emc is in my "computer" room mounted in a rack. I need to move the mill into the garage but, cannot move the computer.
[15:23:28] <aa-danimal-shop> my mill's toolchanger's claw that grabs the tool occasionally lets go too early and it drops the tool
[15:23:34] <frallzor> first test of electronics connected to pc!
[15:23:45] <aa-danimal-shop> horray frallzor!
[15:23:50] <frallzor> not much happening though :P
[15:24:06] <frallzor> Ive forgotten all abot how to config a profile for emc =P
[15:24:23] <aa-danimal-shop> lol
[15:24:28] <frallzor> need to fix the e-stop on the bob first
[15:24:36] <frallzor> its unconnected = constantly triggered
[15:24:43] <SWPadnos> steverob, so you want to have the PC in the rack, connected to the machine (in the garage) with a parallel cable, and the terminal also in the garage, connected to the PC with a serial cable?
[15:25:13] <steverob> I Exactly!
[15:25:20] <SWPadnos> ok, that's not a remote GUI :)
[15:26:25] <SWPadnos> I don't know what has to happen to prevent the penguin image from being displayed - you may have to edit the emc script to do that (or maybe set INTRO_GRAPHIC to nothing in the ini file)
[15:26:28] <MOGLI> hey anyone have idea/hal file so i can use Encoder with Pluto-P Stepper??or is it possible to use 2 hardware in one HAL FILE .. i.e. Step/Dir from Pluto and Encoder in Parallal PORT
[15:26:36] <SWPadnos> you will need to set up an emc2 comfig that
[15:26:38] <SWPadnos> gah
[15:26:53] <SWPadnos> you will need to set up an emc2 config that uses xemc or yemc as the DISPLAY
[15:27:14] <SWPadnos> just run that config by using emc -ini <wherever that ini is> at the command line
[15:27:35] <steverob> I would not have a remote GUI. But, that's OK as long as I have a command line interface to emc.
[15:28:01] <SWPadnos> well, it really depends on what you mean by "a command line interface to emc"
[15:28:20] <SWPadnos> there are user interfaces that use ncurses (xemc, yemc), and show you the machine status
[15:28:39] <SWPadnos> there is a telnet-like interface that you can use as well, just run the client and server on the same machine
[15:28:44] <SWPadnos> err, same PC
[15:29:02] <steverob> Either a telnet session or a dumb terminal.
[15:29:27] <SWPadnos> you'll have to request the status to see what's happening though, the telnet screen won't update itself when something happens
[15:29:38] <frallzor> hmm how to configure E-stop out for pmdx?
[15:30:00] <frallzor> could be nice to have soft e-stop too
[15:31:31] <MOGLI> hey anyone have idea/hal file so i can use Encoder with Pluto-P Stepper??or is it possible to use 2 hardware in one HAL FILE .. i.e. Step/Dir from Pluto and Encoder in Parallal PORT
[15:32:06] <SWPadnos> MOGLI, does the pluto-P stepper config even have encoder inputs?
[15:32:31] <MOGLI> it supports ENCODER in SERVO MODE.. i dont know abt stepper mode thats why asking..
[15:32:46] <MOGLI> and even i dont know how to check it
[15:33:22] <SWPadnos> load your config and use "Show HAL" to see if there are any encoder pins
[15:33:47] <MOGLI> my problem is threading.. pluto-p just works fine ..but for threading i need to attach encoder too. it have input lines..
[15:35:06] <SWPadnos> there are no hardware encoders in pluto-step
[15:35:36] <MOGLI> :(
[15:35:37] <SWPadnos> yes, you can use both pluto and parport drivers in the same config
[15:36:02] <SWPadnos> you'll be limited by the speed that software can count the encoder inputs on the parallel prot
[15:36:04] <SWPadnos> port
[15:36:41] <MOGLI> how?? just simple MERGER???
[15:36:51] <SWPadnos> sort of
[15:37:03] <SWPadnos> you should read about HAL files before trying it
[15:37:21] <SWPadnos> note that you will need a second parallel port - you can't use the same port with both pluto and generic I/O
[15:38:03] <MOGLI> YUP mainboard LPT i am using for PLUTO and NETMOS PCI card for Encoder
[15:38:49] <SWPadnos> ok, that's fine
[15:39:25] <SWPadnos> you can set up the encoder stuff in a completely separate HAL file, and then just load that one with a second "HALFILE=" line in your ini
[15:39:46] <frallzor> how harmful is it to test a stepper with to high current for just a short while?
[15:39:56] <frallzor> just want to see if I can get it all to live
[15:40:08] <SWPadnos> frallzor, you run the risk of destroying the motor, that's all
[15:40:28] <frallzor> getting resistors on a sunday is a bitch =)
[15:40:36] <MOGLI> you mean 2 times "HALFILE=xyz.hal"
[15:40:36] <MOGLI> ??
[15:41:03] <frallzor> guess Ill wait then =(
[15:41:10] <pfred1> why wait?
[15:41:22] <SWPadnos> MOGLI, yes. you can have as many as you want
[15:41:37] <frallzor> since I have no resistors for limiting current..
[15:41:38] <frallzor> =)
[15:41:56] <pfred1> what do you need resistors to limit current for?
[15:42:21] <frallzor> steppers...
[15:42:31] <pfred1> your motor drivers don't go low enough?
[15:42:52] <pfred1> I don't use current limiting resistors I just set my driver right
[15:43:04] <frallzor> guess you dont use geckos =)
[15:43:23] <frallzor> resistors = settings for current
[15:43:32] <MOGLI> thanks SWPadnos..hey one more thing.. i remember ur 200ns latency compilation.. do you have ROUGH documetions type something..
[15:43:33] <pfred1> current limiting resistors went out with big hair in the 80s man
[15:43:57] <SWPadnos> that was mostly due to system optimization, not the kernel
[15:44:23] <pfred1> there should be a pot on the driver to set up the current
[15:44:31] <SWPadnos> I used the SMP kernel that cradek had compiled (for 6.06), and then removed almost everything from the system startup scripts
[15:44:43] <frallzor> pfred1 not, they require resistors
[15:44:46] <frallzor> *no
[15:45:01] <SWPadnos> not so much the BIOS, but remember, there was no X and no network on that machine
[15:45:16] <SWPadnos> (under normal circumstances anyway)
[15:45:28] <pfred1> frallzor well you don't need current limiting resistors you need either sense or setting resistors
[15:45:36] <MOGLI> yaa i know..UBUNTU??
[15:45:41] <MOGLI> or debian??
[15:45:44] <SWPadnos> I also removed all sound and other drivers like that, used ext2 instead of ext3, and had the hard disk mounted read-only
[15:45:56] <frallzor> I need resistors that limits current, they are made that way,
[15:46:01] <SWPadnos> installed from the Ubuntu 6.06 EMC2 liveCD
[15:46:08] <pfred1> SWPadnos EXT3 is EXT2 with a journal
[15:46:13] <frallzor> aka normal resistors that sets the current on the geckos
[15:46:14] <SWPadnos> exavtly
[15:46:15] <SWPadnos> err
[15:46:17] <SWPadnos> exactly
[15:46:32] <SWPadnos> the journaling daemon caused latency spikes every 5 seconds or so
[15:47:02] <MOGLI> hmm.. any other imp thing you rem??
[15:47:11] <SWPadnos> not really
[15:48:07] <pfred1> frallzor in the context of stepper motors current limiting resistors are resistors in line with motor coils
[15:48:20] <MOGLI> thanks..
[15:48:44] <pfred1> frallzor and you don't need those
[15:48:48] <frallzor> In the context of geckos they are just resistors that sets the current
[15:48:56] <frallzor> they connect to the geckos
[15:49:08] <pfred1> damn you mean mariss didn't just plunk a trim pot on his drivers?
[15:50:18] <pfred1> there must be more to it maybe they're sense resistors?
[15:50:47] <pfred1> still for what he's charging he should just throw them in
[15:51:08] <SWPadnos> but how does he know what value you need?
[15:51:21] <frallzor> you cant =)
[15:51:26] <pfred1> SWPadnos for what he's charging he can give a range that would cover the bases
[15:51:48] <frallzor> you still wouldnt know what the current is set to
[15:51:56] <frallzor> unless you can magically feel it =)
[15:52:17] <pfred1> my drives have both sense and set
[15:52:22] <SWPadnos> you would read the resistor values, then select the one you need, and then you would know the current limit ...
[15:52:44] <pfred1> but sense is general one resistor does the range
[15:52:57] <SWPadnos> pfred1, I suppose he could toss in a 10-pack of common values - that would give 0.5A resolution or thereabouts
[15:53:02] <pfred1> that was dependant on the driver IC
[15:53:17] <SWPadnos> but it would be somewhat wasteful as you know 90% of them will go unused
[15:53:21] <frallzor> anyone using pmdx?
[15:53:23] <pfred1> you had a grand total of two choices
[15:53:34] <pfred1> 1.2 or .68 ohms
[15:54:08] <pfred1> so geckos do set and sense all in one?
[15:56:13] <pfred1> well maybe he could have it on the order form you get at least something to get you running
[15:56:40] <pfred1> I mean come on this is worse than batteries not included!
[15:56:46] <pfred1> some parts not supplied
[15:56:59] <SWPadnos> there's a fixed sense resistor, you only need the set resistor
[15:57:16] <pfred1> why the hell didn't he just make it an adjustable trimmer?
[15:57:21] <frallzor> * frallzor is trying to figure out how to connect the e-stop for the pmdx bob
[15:57:30] <skunkworks> http://www.electronicsam.com/images/KandT/conversion/oh_its_a_start.JPG
[15:57:30] <SWPadnos> since the current range is only from 0-7A, and it's not really practical to use the drives for motors smaller than an amp or two, there's no real need to change the sense resistor
[15:57:36] <SWPadnos> ask him
[15:57:58] <SWPadnos> but note that a trimmer is nearly impossible to set to a specific value
[15:58:00] <pfred1> I guess so complete morons didn't burn their houses down but still
[15:58:06] <Jymmm> Trim pots tend to drift.
[15:58:18] <pfred1> SWPadnos must be why i used 15 turns on my drives
[15:58:27] <SWPadnos> well, you can't tune it since it's dynamic - you can't just stick a meter in line and see what the actual current is
[15:58:36] <pfred1> a 15 turn 200 ohm resistor isn't going to drift much
[15:58:47] <SWPadnos> sure, and a good 15-turn pot is several dollars, while the terminals are $0.50
[15:58:56] <pfred1> SWPadnos why not I did
[15:59:07] <SWPadnos> are you making and selling 10000 drives a month?
[15:59:21] <pfred1> no I adjusted my trimmer dynamically
[15:59:31] <SWPadnos> mostly to people who don't have to wait until Monday to get their resistors :)
[15:59:32] <pfred1> with an ammeter in line
[15:59:59] <Jymmm> LOL
[16:00:02] <SWPadnos> then you adjusted it to the wrong current, unless you have a very very special ammeter
[16:00:25] <pfred1> SWPadnos No, I adjusted my drives to the best possible performance i could get out of them
[16:00:37] <Jymmm> ...on this very special episode of Blossom
[16:00:47] <SWPadnos> that's not the same question as adjusting the current limit correctly
[16:00:47] <pfred1> SWPadnos I know the difference between 1 2 and several numbers in fact!
[16:01:15] <SWPadnos> I'm not questioning your reading of the meter, I'm doubtful that using that method will give you the correct adjustment
[16:01:29] <pfred1> I know I want my motors to run as fast as they can with the required torque
[16:02:06] <Jymmm> If you can't hit RS and buy an assotment pack of resistors, sucks to be you!
[16:02:11] <SWPadnos> consider this: a stepper motor coil often has <1 ohm resistance. when you add the meter to that, you may be doubling the resistance of the motor as seen by the drive
[16:02:25] <pfred1> Jymmm have you been to an RS store lately?
[16:02:46] <pfred1> SWPadnos I put the meter before the drive
[16:02:54] <Jymmm> pfred1: http://www.radioshack.com/product/index.jsp?productId=2062303
[16:02:57] <SWPadnos> what kind of drive did you make?
[16:03:02] <SWPadnos> is it a chopper?
[16:03:13] <pfred1> SWPadnos SLA7026 based unipolar
[16:03:23] <pfred1> yes its a chopper
[16:03:53] <pfred1> my SImpson 270 averaged out the draw quite nicely
[16:04:16] <pfred1> needle didn't even waver
[16:04:20] <SWPadnos> ok, so you calculated what the average current draw should be, assuming some level of efficiency and all that jazz, and then tuned to that
[16:04:38] <pfred1> I saw my motors said 2 amps on them and didn't go over it
[16:04:56] <SWPadnos> that's well beyond what a manufacturer who sells to hobbyists can expect his customers to do
[16:04:56] <pfred1> actually they ran best drawing only one amp go figure
[16:05:23] <SWPadnos> is the power supply at a higher voltage than the motor rating?
[16:05:30] <pfred1> quite
[16:05:55] <SWPadnos> in that case, you need to (more or less) divide the current rating by the ratio of the supply voltage to the rated voltage
[16:06:34] <SWPadnos> ie, a 2A/4V motor, run from a 24V supply, should draw about 1/3A from the supply at full current (assuming zero speed)
[16:06:41] <pfred1> I guess I've run my motors for hours on end they warm up but its reasonable
[16:07:22] <pfred1> yeah I'm running them at 23V
[16:07:50] <SWPadnos> that was an example. if you tune for 2A (or 1A) from the 24V side, that's too high a setting
[16:07:52] <pfred1> I'm getting good performance and pull out etc at 926 RPMs
[16:08:19] <SWPadnos> well, as long as it works for you. :)
[16:08:40] <pfred1> yeah its all going rather well for me so far
[16:09:38] <pfred1> I would like to try my drivers on a higher voltage someday to see if I could get any more speed out of them
[16:10:17] <pfred1> I should get some 7805HVs for them though so I can approach the voltage of the driver ICs
[16:10:38] <pfred1> I htink they'll take 44V
[16:11:46] <pfred1> best speed i ever got out of the motors was 2500 RPM but there was no torque there they just spun free
[16:12:57] <pfred1> BTW does EMC support a hold feature?
[16:13:35] <SWPadnos> there are two ways to do this (in realtime) - set adaptive feed override to 0, or set feed_hold to 1
[16:13:51] <SWPadnos> both from motion, I believe
[16:14:07] <pfred1> then you get a separate hold signal?
[16:14:30] <SWPadnos> those are pins that affect motion speed, you can create HAL signals and connect them to whatever you want
[16:14:43] <pfred1> because if i could get a hold signal I could set my drivers up to hold at lower current
[16:15:07] <SWPadnos> oh, are you asking about something that tells the driver when the motor isn't going to move for a little while?
[16:15:24] <pfred1> yes hold input
[16:15:35] <SWPadnos> there is no output of that type in EMC2
[16:15:39] <pfred1> as in axis isn't getting step pulses
[16:16:05] <pfred1> hmm I think geckos have logic external to themselves that do it
[16:16:24] <pfred1> mariss does make some sweet drives
[16:16:25] <SWPadnos> you can stick a timer on the stepgen output if you like, but there will be no advanced warning before a step comes in (requiring the driver to "wake up")
[16:17:11] <pfred1> I was scoping out the parallel step output on my system the otehr day and the pulses ate 100 us apart so timing really isn't an issue there
[16:17:33] <pfred1> TTL would be like 5000 times faster than anythng going on here
[16:18:30] <pfred1> though the actual step pulse itself is only 5 us long
[16:18:31] <SWPadnos> oh, you could make a hardware step detector that can assert the reduced-current hold line as necessary
[16:19:09] <pfred1> yeah i wanted an easier softare solution
[16:19:27] <pfred1> it'd have been nice you know?
[16:19:30] <SWPadnos> or do it in software. if you use software, just be careful to put the step outputs on the parport control pins, and the hold line on the data pins. I believe the data pins are updated first, so that would give the hardware an extra microsecond or so to wake up
[16:20:08] <SWPadnos> otherwise, the hold pin will be changed about a microsecond after the step comes
[16:20:19] <pfred1> yeah that'd be no good
[16:20:25] <pfred1> missed step
[16:20:51] <pfred1> its just something I wouldn't mind implementing in the future is all its added complexity now though
[16:21:02] <SWPadnos> yep
[16:21:39] <pfred1> I gotta hand it to mariss to sell his drivers and deal with all the goofballs plugging them in
[16:21:56] <SWPadnos> and not necessarily all that useful either. even if one axis isn't moving, it still needs to hold still with full force - you wouldn't want Z drifting while you're doing a waterline contour
[16:21:58] <pfred1> better him than me!
[16:22:02] <SWPadnos> heh
[16:22:28] <pfred1> oh come on he's got to tell people not to plug their steppers right into wall juice for crying out loud!
[16:22:49] <pfred1> I've seen him doing it
[16:23:32] <pfred1> I guess he has that one resistor not there just so people give it a little thought
[16:23:59] <pfred1> because you know if it was a trimmer people would be blowing their stuff up left and right
[16:24:20] <SWPadnos> and like I said, they're hard to adjust, unless you use a large/expensive one
[16:24:24] <SWPadnos> s/one/trimmer/
[16:24:48] <pfred1> well with my 15 turn I had to be within an eight of a turn for optimal performance
[16:24:57] <pfred1> it was that picky
[16:25:08] <pfred1> and thats on a 200 ohm trimmer too
[16:25:26] <pfred1> so you're talking like a tenth of an ohm
[16:25:49] <pfred1> yeah it'd run out of there just not nearly as well
[16:25:56] <frallzor> finally, emc knows when I trigger e-stop etc etc now
[16:26:13] <frallzor> tomorrow I hook a stepper up!
[16:26:26] <pfred1> frallzor but will EMC know when I come charging at a machine wiht an axe?
[16:27:00] <frallzor> if you make a sensor that can see you and triggers a high or low signal
[16:27:05] <frallzor> then it can
[16:27:21] <pfred1> heh don't worry machines know when I'm around I donno how but they know
[16:28:17] <pfred1> frallzor I had this computer once and it was acting up so I put a hammer through it man for years I didn't have any problems from any machines that witnessed that!
[16:29:25] <pfred1> * pfred1 knows how to fix cantankerious machinery!
[16:29:54] <frallzor> http://pici.se/p/ZfQTOWHwU/ these are my babies
[16:32:48] <pfred1> firefox sux you can't just paste a URL into the window
[16:33:51] <pfred1> frallzor are those your jog controls on the top of the box?
[16:35:02] <frallzor> nope
[16:35:33] <frallzor> enable, disable, light for enable (top)
[16:35:38] <pfred1> well the big red button is estop right?
[16:35:55] <pfred1> what are the rotary switches for?
[16:35:56] <frallzor> e-stop, reset after e-stop, main breaker
[16:36:39] <pfred1> the black knob looking things?
[16:37:07] <frallzor> knobs for the box =)
[16:37:09] <pfred1> frallzor do you have or are you planning on a jog pendant?
[16:37:10] <frallzor> open, close
[16:37:22] <frallzor> got an extra p-port card to put in the pc
[16:37:30] <frallzor> and connect pendant to it
[16:37:54] <pfred1> yeah I got my port card fired up yesterday
[16:38:07] <pfred1> took me two guesses on the ioport
[16:38:21] <pfred1> but it seems to be working now
[16:38:53] <pfred1> the tutorial was wrong in my case mine was the second number
[16:39:39] <pfred1> but it was neat I hooked my oscilloscope to the port and just ran stepconf in test axis mode to figure it out
[16:40:21] <pfred1> and got some other meaningful data out of the experience too
[16:40:59] <pfred1> today is see if my port buffer works or not
[16:42:43] <pfred1> big netsplit!
[16:43:24] <pfred1> oh well off to get this board connected here
[16:45:48] <pfred1> hey we're all back!
[16:46:17] <WalterN> what happened? netsplit?

[17:13:24] <pfred1> oh this is just plain silly I'm down to my last 6" steel rule?
[17:13:40] <pfred1> up found another one!
[17:18:27] <frallzor> found some nice resistors, but no go when trying out in emc
[17:18:34] <frallzor> any idea what is wrong?
[17:18:56] <frallzor> the steppers get hold torque
[17:20:50] <pfred1> frallzor did you try swapping two leads in a pair?
[17:21:19] <frallzor> as in A and A_
[17:21:34] <pfred1> yes
[17:22:38] <frallzor> switched all now
[17:22:40] <frallzor> will try again

[17:26:47] <pfred1> frallzor you have a multimeter with frequency reading?
[17:27:45] <frallzor> ahhh
[17:27:57] <frallzor> step dir is dir step for my board
[17:28:10] <pfred1> how about just set the step timing really low?
[17:28:14] <frallzor> its not the default
[17:28:34] <pfred1> so you can see the phase changes coming out of the driver on what you do have
[17:28:34] <frallzor> need to change all steps to dir and dir to steps in config
[17:29:51] <pfred1> heh your motor moved once on change of direction?
[17:30:35] <frallzor> no since it was configured wrong in emc
[17:31:46] <frallzor> but still no go
[17:31:47] <frallzor> hmm
[17:32:10] <pfred1> hey if this was that easy everyone would be doing it
[17:34:43] <frallzor> what could be wrong, hmmm
[17:37:04] <pfred1> oh that's rightious!
[17:37:43] <pfred1> * pfred1 just mounted his port buffer board to a piece of scrap whiteboard he had laying around ...
[17:38:07] <pfred1> almost like it was made for it or something I'm telling ya
[17:39:29] <frallzor> I hate this!
[17:40:01] <pfred1> frallzor first thing is relax its not like the motor driver is runing your pacemaker now is it?
[17:40:18] <frallzor> it is
[17:40:42] <pfred1> its still nothing to get all worked up about I'm sure its something simple
[17:41:26] <pfred1> geckos have some kind of an outragious setup time to them
[17:41:40] <pfred1> you may not be giving your driver the setup time it needs
[17:41:58] <frallzor> there are settings for 203V in emc
[17:42:38] <pfred1> * pfred1 has a smoke ...
[17:44:01] <frallzor> should gnd or 5v be the commone reference for the geckos?
[17:44:05] <frallzor> anyone know? =)
[17:44:27] <pfred1> gnd I'd imagine
[17:45:09] <pfred1> working out my circuit there was no easy way to isolate gnd so I didn't even bother
[17:45:20] <pfred1> there was gonna be paths anyways
[17:46:07] <pfred1> the moment of truth is coming close here
[17:48:17] <pfred1> * pfred1 warms up the 'scope ...

[18:00:16] <frallzor> this is a bitch
[18:06:43] <pfred1> whoot!
[18:06:58] <pfred1> heh my motor is running in a cardboard box
[18:07:13] <frallzor> what be wrong, what be wrong.... hmmm
[18:07:42] <pfred1> oh thats cool in stepper conf I got it changing directions now
[18:08:23] <pfred1> though initially I did transpose my step and dir signals here
[18:08:34] <pfred1> * pfred1 has to better document some of this crap
[18:09:43] <TD--Linux> TD--Linux is now known as TD-Linux
[18:12:56] <pfred1> man thats validiction there for ya
[18:14:00] <pfred1> the run button is a little weird in Axis configuration isn't it?
[18:28:28] <frallzor> * frallzor is scratching his head
[18:32:09] <skunkworks> frallzor: what is your setup?
[18:34:54] <frallzor> hmm might have found the issue now
[18:34:58] <frallzor> testing
[18:36:55] <frallzor> hmm no this seems too odd
[18:37:25] <frallzor> pmdx 132 with 4 g203v
[18:37:31] <frallzor> cant get em to spin
[18:39:31] <frallzor> skunkworks check page 16 in this: http://www.pmdx.com/Doc/PMDX-132_Manual_12.pdf
[18:39:47] <frallzor> does it mean I have to setup emc after J7 in that table?
[18:40:00] <frallzor> since im using that way of connecting
[18:44:29] <pfred1> frallzor when I release my dead simple open source completely free CNC hardware you'll be my first customer right?
[18:44:39] <frallzor> nope =)
[18:45:02] <pfred1> but hey my motor is running over here!

[19:11:07] <WalterN> ever have pickled garlic?
[19:11:36] <skunkworks> garlic stuffed green olives.. Mmmmmm
[19:11:40] <pfred1> I've had nasty white pizza with so much garlic on it i wanted to choke
[19:11:58] <WalterN> skunkworks: with jalapeƱos :D
[19:13:14] <skunkworks> anyone have a good wave shaping circuit for turning an inductive pickup to a square wave?

[19:17:39] <pfred1> people who can't cook hide the fact wiht liberal helpings of garlic!
[19:17:42] <frallzor> fixed!
[19:17:51] <frallzor> thanks to Mr DaViruz
[19:18:19] <pfred1> frallzor what'd you have to do?
[19:18:56] <frallzor> the common
[19:19:04] <frallzor> was set to +5v instead of gnd
[19:19:23] <pfred1> oh thats not good
[19:20:47] <frallzor> no it wont work then
[19:20:50] <frallzor> nothing else
[19:20:52] <frallzor> =)
[19:21:56] <pfred1> well I told you it'd be something simple didn't I?
[19:32:25] <frallzor> I need clean up in isle "my pants"
[19:32:53] <frallzor> aisle even
[19:43:07] <renesis> guys guys
[19:43:33] <frallzor> I'm a MAN
[19:43:41] <renesis> besides the latency benchmarks table on the wiki, does anyone have more info about emc on atom mobos?
[19:44:42] <pfred1> hey how come in stepconf wizard when I change the first parport base address it always goes back to 0x378?
[19:45:14] <micges> pfred1: what emc version?
[19:45:45] <pfred1> Linux cnc1 2.6.24-16-rtai #1 Tue Sep 30 22:54:33 EEST 2008 i686 GNU/Linux
[19:45:45] <renesis> omg no halp!
[19:45:50] <renesis> k ty bbl
[19:46:08] <pfred1> /exec -o uname -a
[19:46:26] <pfred1> its not that old couple of months?
[19:46:41] <micges> pfred1: type emc in console
[19:47:02] <pfred1> EMC2 - 2.3.5
[19:48:11] <pfred1> I mean i go through the whole wizard and say save changes at the end and this is like a half a dozen times now it keeps on reverting to the default ioport number
[19:49:02] <pfred1> I'm just getting a bit tired turning it back everytime I want to play move the motor over here
[19:50:05] <micges> let me check
[19:50:51] <pfred1> * pfred1 plays move the motor again ...
[19:52:51] <pfred1> that is just too cool to hit a button on the screen and the motor runs
[19:54:20] <pfred1> BTW what is the trick with the "run" button in Axis Test?
[19:55:40] <pfred1> I hit and it runs sure enough but I hit it again and it doesn't always want to stop running
[19:57:09] <micges> pfred1: it works here.. can you pastebin.ca your *.hal and *.stepconf files?
[19:57:13] <pfred1> * pfred1 likes to go back and forth between "Run" and "jog"
[19:57:33] <pfred1> micges yeah sure np where are they?
[19:58:14] <micges> in /home/some user/emc2/configs
[19:58:27] <micges> (default location)
[19:58:39] <pfred1> OLK just closes stepconf again and applied
[19:59:18] <pfred1> ought oh this may be why I have a my_mill and a my-mill1
[20:00:45] <pfred1> which one would this stepconf be using?
[20:01:12] <pfred1> 2010-03-27 20:08 my-mill_1.stepconf or 2010-03-28 15:58 my-mill.stepconf
[20:01:35] <pfred1> one of these has got to go!
[20:02:07] <micges> latest I think
[20:02:40] <pfred1> alright this is probably the problem I probably saved the one conf when I got the motor running
[20:03:00] <pfred1> so let me put the other one in some other dir see if I still have the problem thanks
[20:03:18] <micges> ok
[20:04:20] <pfred1> now let me see if it keeps on doing this scewrieness to me or not
[20:05:43] <pfred1> hrm I think I lost all of my previous settings
[20:06:12] <micges> restore it from backup
[20:06:31] <pfred1> well I want to stick with one file for now I'll just redo it
[20:08:49] <pfred1> I still think you guys should do some work on this "Run" button its flakey
[20:09:38] <pfred1> ok I went through it all and saved it now I'm opening it up again
[20:10:03] <pfred1> first parport address went back!
[20:11:03] <pfred1> but now I only have one file in my config directory called my-mill.stepconf
[20:12:26] <micges> its correct
[20:12:42] <micges> and in my-mill directory you have rest of config
[20:13:20] <pfred1> micges but it changed my ioport back to 0x378
[20:13:32] <pfred1> or whatever the heck the default is
[20:13:44] <pfred1> 0x378
[20:13:59] <micges> oh so pastebin files I've asked
[20:14:04] <pfred1> I would think that apply at the end would change that
[20:14:18] <pfred1> so you want this my-mill.stepconf file?
[20:14:21] <micges> it should
[20:14:29] <micges> yes
[20:14:33] <pfred1> OK sec
[20:15:33] <pfred1> http://pastebin.com/CGg421AV
[20:15:56] <pfred1> now I'm going to play run the motor for a while over here
[20:17:22] <pfred1> man this thing isn't saving anything over here anymore don't I have write perms to the dir?
[20:19:32] <micges> pfred1: it works here
[20:19:49] <pfred1> micges well fluff up the pillows I'm coming over!
[20:20:22] <pfred1> because it sure ain't working here
[20:21:27] <micges> try run stepconf from console and see if there are any errors and if so pastebin them
[20:21:37] <pfred1> ok
[20:22:10] <pfred1> I remember going through all kinds of stuff to to get my motor running a little better a while back too
[20:22:28] <pfred1> so I do want this all to save I mean it was saving
[20:25:40] <pfred1> micges first link: http://pastebin.com/Pp35Mvjq
[20:27:18] <pfred1> but I also see i was flying by this page too fast with the Do you wish to: line :)
[20:30:02] <pfred1> still seriously there's something up with that Run button in text axis
[20:30:02] <pfred1> test axis even
[20:33:41] <pfred1> man I'm like a 2 year old with this stuff I can't help it
[20:36:36] <owhite> hello people. A lot of the tcl code in emc refers to environmental variables like $EMC_INIFILE. Does anyone know how I can view these environmental variables on the unix command line? Using "env" does not work.
[20:37:02] <Jymmm> cat
[20:37:22] <Jymmm> echo $LANG
[20:37:28] <Jymmm> etc
[20:37:33] <SWPadnos> they're set in the emc script, so they're gone by the time emc exits, and they don't exist in the environment of other shells
[20:37:53] <SWPadnos> you can use a debug parameter to print them out, maybe emc -d or -v or something
[20:46:03] <pfred1> whats like a good velocity?
[20:47:37] <tom3p> any vector libs used in emc's python side? i want to add and subtract things like this pts=[(100,100),(10,0)] tmp= pts[0} + pts[1]
[20:47:45] <cradek_> pfred1: 75 mph
[20:48:01] <Jymmm> Speed of light in a vacuum
[20:48:34] <cradek_> tom3p: maybe check out python-numarray
[20:48:39] <tom3p> thx
[20:48:47] <pfred1> Jymmm i saw a guy on TV once that figured out how to go faster than the speed of light
[20:49:18] <pfred1> then they showed this other guy who slowed light down to 60 MPH
[20:52:39] <pfred1> my motor does not sound healthy when I choose 1.7 in/s
[20:57:45] <pfred1> * pfred1 needs those new optos
[21:02:32] <tom3p> cradek: python-numarray is sweet, thx again, and if anyone needs it, theres a good pyhon-numarray-doc pkg to explain it
[21:14:13] <pfred1> hey anyone want to see my test rig?
[21:15:23] <frallzor> I want to see cottage cheese
[21:16:30] <pfred1> frallzor I had my motor running over 1000 RPM
[21:21:14] <JT-Hardinge> I need to take a video of turning at 6000 RPM and threading at 1500 RPM on the CHNC
[21:28:17] <Jymmm> JT-Hardinge: what kind of threading?
[21:29:02] <JT-Hardinge> lathe
[21:29:14] <JT-Hardinge> the CHNC-I
[21:29:41] <Jymmm> JT-Hardinge: Greek ---> CHNC-I
[21:29:55] <JT-Hardinge> HARDINGE!
[21:30:15] <Jymmm> I'll take your word for it
[21:31:17] <JT-Hardinge> http://www.youtube.com/watch?v=Dtas5hNyrfI
[21:34:42] <Jymmm> JT-Hardinge: is that YOUR video?
[21:34:49] <JT-Hardinge> no
[21:35:24] <Jymmm> how many tools can you have on that?
[21:36:24] <JT-Hardinge> 8
[21:36:34] <JT-Hardinge> do you have to call a while loop?
[21:37:00] <Jymmm> Typically, a WHILE loop is ALWAYS executed in most langs
[21:37:26] <JT-Hardinge> in g code
[21:37:28] <JT-Hardinge> ?
[21:37:34] <Jymmm> That I don't know.
[21:37:53] <frallzor> http://vimeo.com/10506441 first run ever with my steppers =)
[21:38:00] <JT-Hardinge> this IS my lathe http://www.youtube.com/watch?v=LSrJjg-nlB8
[21:38:02] <Jymmm> WHLE is usually used to catch a condition
[21:38:25] <Administrator_> hi John
[21:38:48] <Jymmm> JT-Hardinge: Did you rebuild that?
[21:38:57] <JT-Hardinge> Administrator_: hi Dan
[21:39:04] <Jymmm> JT-Hardinge: it looks WAY too clean =)
[21:39:10] <Administrator_> dammit it changed my name again
[21:39:20] <Administrator_> Administrator_ is now known as aa-danimal-shop
[21:39:38] <aa-danimal-shop> there
[21:39:58] <JT-Hardinge> I integrated EMC and Mesa into it and fixed all that was borked
[21:40:22] <JT-Hardinge> aa-danimal-shop: Dan you do any while loops?
[21:40:52] <aa-danimal-shop> wtf is that?
[21:42:37] <JT-Hardinge> LOL
[21:43:17] <pfred1> wtf is what?
[21:43:48] <pfred1> aa-danimal-shop want to see my motor hooked up to emc?
[21:43:50] <Jymmm> JT-Hardinge: http://wiki.linuxcnc.org/emcinfo.pl?Example_G-Code_Programs#Using_a_while_loop_to_make_circular_indents_in_the_side_of_a_hand_wheel
[21:44:55] <aa-danimal-shop> sure
[21:45:05] <pfred1> aa-danimal-shop http://www.imagechicken.com/uploads/1269814572086495500.jpg
[21:45:35] <pfred1> my mad buffer board didn't blow up my emc machine!
[21:45:44] <aa-danimal-shop> hah cool
[21:46:06] <pfred1> yeah I wasn't 100% about it thats for sure
[21:47:00] <JT-Hardinge> Dueling Simpsons!
[21:47:20] <pfred1> heh yeah well when I see them I grab them
[21:47:30] <pfred1> one cost me a whopping $3
[21:48:05] <JT-Hardinge> theres some things you can't see on a digital meter
[21:48:24] <pfred1> oh i love the twins
[21:48:48] <pfred1> ones a 260 series 3 the others a 270 series 4 so they're not identical
[21:49:09] <JT-Hardinge> looks ok on the backplot hand on the oh shit button here we go
[21:50:55] <pfred1> I'm torn on whether i should order new optos for my motor drivers or not on the one hand what i have seems to work on the other hand they're dog slow and I don't evne know why they work
[21:51:26] <pfred1> their latency should be 6X over the pulses they're transmitting
[21:51:47] <pfred1> least if I go by the part spec sheet
[21:52:32] <aa-danimal-shop> does amd own ati now?
[21:52:44] <aa-danimal-shop> their website is now combined
[21:52:59] <pfred1> yes
[21:53:05] <aa-danimal-shop> interesting
[21:53:24] <pfred1> and last i heard AMD ain't doing so swift either
[21:53:41] <pfred1> Intel buried them with fab plant creation
[21:53:49] <aa-danimal-shop> i'm trying to get one of those dvi to component video adapters to work
[21:54:12] <pfred1> intel is holding back like 3 gens of chips right now
[21:54:28] <JT-Hardinge> NOW were cooking with gas!
[21:54:30] <aa-danimal-shop> it "works", but the resolution is wrong
[21:56:17] <frallzor> * frallzor is drinking red bull
[21:56:44] <pfred1> * pfred1 was born a red bull
[21:57:21] <JT-Hardinge> Dan you should have seen that
[21:59:42] <JT-Hardinge> DANG PASbin is borked
[22:00:03] <pfred1> I had troubles with imageshack earlier thats why I used imagechicken :)
[22:01:05] <JT-Hardinge> is there a pastechicken
[22:01:24] <pfred1> I know there's more than one pastebin there's like different countries
[22:01:33] <pfred1> like pastebin.us
[22:02:24] <JT-Hardinge> aa-danimal-shop: here is a while loop to turn down a part from 0.750 to 0.1875 http://pastebin.com/wJWrB6Xm
[22:02:26] <pfred1> hey I never knew pastebin would compile and run code fot you too
[22:02:53] <JT-Hardinge> using CSS too in that code
[22:03:54] <JT-Hardinge> * JT-Hardinge wanders off to the neighbors house to play with guns
[22:04:24] <pfred1> http://web.archive.org/web/20020721022959/www.parseerror.com/paste/ <--- #php pastebin - the world's second largest collection of bad code
[22:04:38] <aa-danimal-shop> JT-Hardinge, cool!
[22:04:43] <aa-danimal-shop> good to know
[22:05:16] <pfred1> chicken paste doesn't sound very appetizing to me really
[22:06:00] <pfred1> they raise a lot of chickens around here and sometimes they don't get the cages closed so they like fall out on the sides of the road and you pass a chicken wandering around
[22:07:06] <pfred1> well if you're white you pass it I bet everyone doesn't!
[22:13:02] <pfred1> hey andy panda
[22:13:32] <andypugh> Pandy?
[22:13:41] <pfred1> andypugh check out the mess i made today: http://www.imagechicken.com/uploads/1269814572086495500.jpg
[22:13:55] <owhite> Jepler: are you on line?
[22:14:23] <pfred1> owhite are you in Maryland?
[22:14:26] <andypugh> That side looks good.
[22:14:36] <owhite> yes, in maryland.
[22:14:44] <pfred1> andypugh thanks its running like a raped date too
[22:14:57] <pfred1> owhite hey I'm right next door in Delaware
[22:15:18] <pfred1> in the land of many chickens
[22:15:29] <owhite> hey good to know. what kind of machine are you running?
[22:15:54] <pfred1> owhite I'm still trying to build something over here
[22:16:14] <owhite> always fun. took me about 3 years to get mine going. :-)
[22:16:20] <pfred1> so far I've made some motor drivers and a port buffer board
[22:16:34] <andypugh> I spent the weekend boring out the column of my mill to take a ball nut.
[22:16:51] <pfred1> andypugh how'd that go?
[22:17:22] <pfred1> andypugh sounds like you had a very boring weekend to me
[22:18:38] <andypugh> Well, the actual boring took very little time. Fixing the boring machine (motor centrifugal switch overhaul, then wiring out the thermal oveloads when that wasn't the problem) then making a long-enough boring bar (including a lot of fiddling with the cylindrical grinder and a too-soft wheel) and finding a bit of actual tool steel to go in the boring bar took the majority of the time.
[22:19:20] <pfred1> yeah when I got my mill the starter switch was bad on it
[22:19:54] <pfred1> for years I had an external momentary switch I'd use to start it it was almost a safety feature being as you had to have hands on two siwtches to start the thing
[22:20:15] <pfred1> then when another wire burnt out in the motor I finally got around to fixing it right
[22:21:36] <andypugh> We think that the heater coils have corroded or something, there was no sign of the motor getting even slightly warm. And worst-case we would burn out an ancient, oversized, single phase 1hp motor that has terminal rubber rot on it's internal wiring.
[22:22:03] <pfred1> nothing like that chinese stuff where quality is job one million seven hundred and fifty eight thousand four hundred and fifty sis huh?
[22:22:35] <owhite> "Waiting for other session to finish exiting...lockfile still not removed" anybody know how to bring emc down even if the GUI is not up?
[22:22:39] <pfred1> at least that was the case with me
[22:22:51] <pfred1> just del the lockfile
[22:23:07] <pfred1> heck netscape was so bad with that stuff I wrote a shell script to do it
[22:23:21] <pfred1> it's in /var/lock
[22:23:26] <owhite> thank.
[22:23:59] <owhite> nothing in /var/lock
[22:24:07] <pfred1> no subdirs in there?
[22:24:16] <owhite> no.
[22:24:46] <andypugh> Is emc up, or just HAL?
[22:25:20] <owhite> it seems like its backing emc out...
[22:27:21] <owhite> any tcl programmers on line?
[22:27:34] <owhite> trying to figure out something in axis.
[22:27:55] <alex_joni> owhite: axis isn't written in tcl iirc
[22:28:05] <alex_joni> python+tk
[22:28:33] <owhite> yeah I got it. but it makes an exec to some tcl programs in its menu and that's what I was wondering about.
[22:28:59] <pfred1> I never knew tcl and tk ever came without the other
[22:29:24] <owhite> but you're right it will make it this a python-tk and tcl/tk question.
[22:29:41] <micges> owhite: ask
[22:29:45] <pfred1> tickle me elmo!
[22:30:22] <owhite> axis.tcl has some lines...
[22:30:30] <owhite> .menu.machine add command \
[22:30:30] <owhite> -command {exec $env(EMC2_TCL_DIR)/bin/emccalib.tcl -- -ini $emcini &}
[22:30:30] <owhite> setup_menu_accel .menu.machine end [_ "_Calibration"]
[22:30:53] <pfred1> micges fooling around with my motor some more i noticed that the Run button in stepconf would stop it at the end of a traverse
[22:30:57] <owhite> which gives me the impression that its passing an argument -ini to the program emccalib.tcl
[22:31:17] <owhite> but, there doesnt seem to be any code in emccalib.tcl thats actually reading the arguement.
[22:31:42] <owhite> I am trying to make a tcl program that _would_ get an arguement, and I'm looking for an existing example.
[22:31:50] <micges> pfred1: lpt port is saved properly?
[22:32:17] <pfred1> micges oh yeah i was an idiot i was flying by the second window without reading it and creating a new configuration every time
[22:32:39] <pfred1> micges i just wanted to get to the test axis so I could fool with my motors you know?
[22:32:50] <micges> :P
[22:33:08] <pfred1> but the run button only stops on a change of direction
[22:33:17] <pfred1> like there is a delay
[22:33:45] <pfred1> well depending on when you hit it that is if you hit it right before a direction change i guess it'd stop right away
[22:34:59] <pfred1> I just think that could be done a little better
[22:35:09] <pfred1> like stop when i hit the button!
[22:35:43] <micges> any ideas are welcome but I am on 9.04 machine and can't test it
[22:36:16] <pfred1> well keep it in mind for the next release then
[22:36:46] <pfred1> I didn't even notice what it was actually doing until I lowered the test area and watched it
[22:37:47] <pfred1> I just kept on hitting the button like a spaz and it seemed to randomly stop at times before that
[22:42:24] <micges> owhite: this is little messy
[22:42:39] <owhite> I can live with messy.
[22:43:07] <micges> ini file handling of emccalib.tcl is in src/emc/usr_intf/emcsh.cc
[22:43:28] <micges> object at line 386
[22:44:11] <owhite> micges, sorry did you put it into a code repository somewhere?
[22:44:13] <pfred1> I'm so indecisive with this get new optos hting here i finally had to toss a coin to decide
[22:44:50] <WalterN> <3 starwars
[22:45:06] <micges> this object is accesible from tcl script in emc like this: "set numaxes [emc_ini "AXES" "TRAJ"]"
[22:45:48] <owhite> ah. I'm after the ini file path and location.
[22:46:06] <micges> owhite: http://git.linuxcnc.org/gitweb?p=emc2.git;a=blob;f=src/emc/usr_intf/emcsh.cc;h=d4ddf3f8b3aca91d74762b03ab73433723f5e83b;hb=b0d9d5ffd85623fb0db06ac0a38bd4051589d165
[23:20:47] <jimbo> I am working with OR2 in 2.4pre I see signal with halmeter on or2.0.in0and 1 but no output on or2.0.out?
[23:21:30] <andypugh> aa-danimal-shop: Have you sold any kit to this guy?
[23:21:32] <andypugh> http://www.youtube.com/watch?v=Z19zFlPah-o
[23:22:22] <aa-danimal-shop> i dont think so
[23:22:48] <andypugh> He appears to be exempt from the lawas of physics.
[23:29:35] <jimbo> I have also tried it with 2.3.x still the same no output on or2.0.out
[23:32:15] <aa-danimal-shop> to see the or2.0.out, you must be the or2.0.out
[23:33:29] <aa-danimal-shop> jimbo, do you have the or2 component added in hal?
[23:34:05] <jimbo> I loaded the or2 component with loatrt.
[23:34:14] <jimbo> loadrt
[23:35:15] <cradek_> you probably forgot to addf it to a thread
[23:35:21] <cradek_> cradek_ is now known as cradek
[23:35:26] <aa-danimal-shop> addf 0r2.0 or something like that?
[23:35:42] <aa-danimal-shop> cradek beat me to it
[23:36:20] <aa-danimal-shop> you gotta add the function to the thread
[23:36:26] <jimbo> I did not add it to a thread I will give that a go.... Thanks...
[23:36:42] <aa-danimal-shop> no prob
[23:37:25] <aa-danimal-shop> my mill's atc is dropping tools occasionally, but i cant get it to replicate the problem now
[23:37:59] <aa-danimal-shop> the claw was opening too early before
[23:38:54] <aa-danimal-shop> but only on occasions.
[23:39:13] <aa-danimal-shop> i adjusted the reed switches on the cam, maybe it fixed it
[23:43:22] <aa-danimal-shop> hmm maybe it's ok
[23:43:52] <aa-danimal-shop> i hope so... dropping carbide endmills on iron gets expensive quick
[23:55:38] <cradek> ouch
[23:56:11] <pfred1> * pfred1 slips a piece of foam under aa-danimal-shop's tool holder to see what he can catch ...
[23:56:37] <andypugh> depending on what the iron is, very expensive.
[23:57:11] <aa-danimal-shop> andypugh, i'm more concerned about the carbide
