[00:54:31] <Ziegler> where is the *.sh script for making the install in ubuntu easier? (Im not using the live cd)
[00:56:12] <SWPadnos> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Installing_EMC2
[00:59:05] <Ziegler> thanks
[00:59:26] <Ziegler> decided to go with x-ubuntu again instead of the live cd
[01:00:33] <Ziegler> fwiw... I was actually on the page... just blind with it starting me in the face :-\
[01:00:38] <SWPadnos> heh
[01:00:54] <SWPadnos> I used the firefox search /.sh
[01:01:09] <SWPadnos> found it pretty quickly, or I wouldn't have seen it wither
[01:01:13] <SWPadnos> either
[01:01:43] <Ziegler> (heh... thats what I had to do myself)
[01:02:15] <Ziegler> you reassured me that I wasnt looking in the wrong place
[01:02:27] <SWPadnos> good deal then
[01:02:28] <Ziegler> goes to show... I needed to just look a bit harder
[01:08:11] <fenn> * fenn fixes the ugly formatting
[01:09:56] <fenn> maybe i should get rid of the breezy stuff too
[01:17:36] <jepler> fenn: yeah at this point I'd say that's fine
[02:12:06] <fenn> alex_joni: a 12 strut fscking oligopod! http://www.itwm.fhg.de/en/mdf__projects__hexapod/hexapod/1/
[02:34:19] <fenn> * fenn mumbles about non-linear accel curves
[02:34:31] <fenn> motor-speed dependent
[02:35:08] <fenn> you could gather this information with halscope easily enough
[02:47:49] <Ziegler> working on standard_pinout.hal
[02:48:15] <Ziegler> I have estop physical button hooked to pin 10 of the parallel port
[02:48:56] <Ziegler> Do I need the #create signal for estop loop back?
[02:58:02] <fenn> # is just a comment line
[02:58:42] <fenn> what those lines do is loop the estop out to estop in, effectively shorting out the estop circuit (so it doesnt do anything)
[03:00:50] <jepler> if you have a momentary switch to reset the estop condition, you may find this useful: http://linuxcnc.org/docs/2.1/html/man/man9/estop_latch.9.html
[03:03:31] <Ziegler> fenn.. realized it was a comment was talking about the lines underneath
[03:03:45] <Ziegler> thanks for the explanation though
[03:03:50] <Ziegler> jepler: thanks for the link
[03:04:54] <Ziegler> I have an actualy e-stop button... reset by twisting clockwise
[07:25:55] <a-l-p-h-a2> a-l-p-h-a2 is now known as a-l-p-h-a
[07:50:22] <lerman__> lerman__ is now known as lerman
[08:01:33] <renesis_> renesis_ is now known as renesis
[08:26:15] <ADucci> what pin do you generally connect your plasma cutter to (in a plasma setup with steppers)?
[08:26:18] <ADucci> and hello..
[08:36:45] <fenn> motion.spindle-on would make sense i think
[08:49:06] <ADucci> i wonder if thats the norm?
[08:56:53] <alex_joni> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Torch_Height_Control
[10:06:41] <fenn> this one should look familiar http://fenn.dyndns.org/pub/sketches/emc-splash/mazak.png
[10:56:12] <alex_joni> fenn: cool, but no tool :P

[18:06:56] <Paragon37> Hello All
[18:07:31] <Paragon37> cradek are you here?
[18:43:51] <skunkworks_> Hi
[18:46:11] <Paragon37> Hi there...
[18:46:45] <Paragon37> Can I ask a question which is off topic but linux related?
[18:47:52] <archivist> someone may know, or know a better place
[18:50:18] <Paragon37> OK here what I am trying to achieve ...
[18:54:28] <Paragon37> I wish to connect to my linux box @ home from work but port are nailed down no ssh out etc so I am unable to tunnel then x11vnc through the tunnel. On windows there is something called logmein www.logmein.com which relays via the web ie one connects to there server via http they connect to your machine which has a logmein client running that relays home pc desktop back to logmein then onto...
[18:54:29] <Paragon37> ...the browser located at work all via port80. is there anything for Linux that can do this?
[19:02:20] <cradek> Paragon37: you might try asking in #ubuntu
[19:10:24] <Paragon37> May have a solution ... Just installed vmwareserver on emc ubuntu ... I can install window in that server then download and install vpn-1 (as I have remote vpn) then run an xserver in windows to connect to the local machine X display. I should be able to connect back to the windows box from work with remote login and view the Linux box ... not the most efficient but hey ....

[19:13:02] <jlmjvm> SWPadnos:when I try to use the command from yesterday it gives me an error
[19:14:08] <jlmjvm> HAL:130: ERROR: parameter or pin 'ppmc.0.dout.02.out-invert' not found
[19:15:06] <cradek> "I got a new lathe" + "I need some cat furniture" = ?

[19:15:29] <jlmjvm> http://pastebin.ca/724645
[19:22:42] <jlmjvm> cradek:do you know what this error is?
[19:23:39] <cradek> jlmjvm: yes, that parameter or pin is not found
[19:24:19] <cradek> I don't have a ppmc, but you do, so you should use the tools available to you to figure out the right name
[19:24:38] <cradek> you can use halshow or halcmd to do that
[19:24:45] <jlmjvm> what im trying to do is invert the brake signal
[19:25:31] <jlmjvm> this is what i added to the hal file:setp ppmc.0.dout.02.out-invert 1
[19:25:35] <cradek> take that line out, run emc, run halshow or halmeter, look at the list of available pins/parameters
[19:25:40] <jlmjvm> k
[19:25:42] <cradek> then you will figure it out
[19:26:31] <cradek> (halshow, halcmd, or halmeter)
[19:35:59] <skunkworks_> Aducci: I see it worked :)
[19:36:21] <Aducci> yip... man, i struggled on that, Thanks a mil!
[19:36:51] <Aducci> new to Linux, CNC, Plasma, EMC....
[19:36:53] <Paragon37> cradek: what is the model number of the pittman servos you are using on your lathe?
[19:37:18] <cradek> I don't know, can you maybe see in one of the photos?
[19:37:39] <cradek> they are marked 19.1V or some other silly number
[19:46:18] <Paragon37> I think they are lo-cog 9000 series but am not sure. Do you know the torque they produce?
[19:46:27] <cradek> sorry no
[19:46:45] <cradek> the stall current is 2-3A I think
[19:46:52] <Paragon37> gear ratio?
[19:47:13] <cradek> ummm
[19:47:24] <cradek> it might be 3:1
[19:47:34] <cradek> I have forgotten a lot of the details
[19:47:38] <lewin1> lewin1 is now known as lewing
[19:47:57] <Paragon37> No problem thanks anyway :-)
[21:40:23] <fenn> on the mazak, how does the spindle drawbar grab the knob on top of the cat-40 toolholder if the knob is what's holding the toolholder in the "pod"?
[21:42:15] <jlmjvm> theres an expanding collet that grabs the retention knob of the tool holder
[21:42:16] <cradek> in the pod the holders are held by their flange/taper
[21:43:08] <cradek> the knob is only used in the spindle
[21:44:23] <fenn> ok, i thought the ball-bearings in the pod grabbed onto the knob
[21:44:52] <cradek> in the swinging arm, the holder is definitely held just by its flange
[21:45:16] <fenn> oh, duh. the arm grabs onto the cat-40 not the pod
[21:45:25] <cradek> in the turret there's some kind of collar but I'm having trouble remembering exactly what it looks like
[21:45:48] <cradek> right, the holder is pivoted down from the turret and then the arm grabs the flange only
[21:48:10] <fenn> there, finally found the youtube video
[21:56:28] <cradek> maybe the knob does hold the holder in the turret (ball bearings in the sleeves)
[22:00:08] <Ziegler> bah... login window resolution a screwed up in ubuntu
[22:01:13] <Ziegler> I even deleted all the availible resolutions except the one I wanted from xorg... and it is still wrong
[22:01:20] <Ziegler> not a big deal... but its annoying
[22:19:52] <Ito-Brazil> Hello ALL
[22:20:30] <Ito-Brazil> I´m getting a huge problem with a CNC heare
[22:20:40] <Ito-Brazil> dunno how, it looses steps all the time
[22:20:54] <Ziegler> to fast?
[22:21:12] <Ziegler> too much resistance?
[22:21:19] <Ito-Brazil> reducing speed, accel, averything... and low speed seems like the problem is bigger
[22:21:41] <Ito-Brazil> my X axis is lighter than Y axis (Y carries X and Z)
[22:22:29] <Ito-Brazil> i´m about to cry : [´´´´, i remade all electronics
[22:23:06] <Ito-Brazil> lol, but i tried all, reducing speed is worst thank more speed
[22:23:17] <Ito-Brazil> PLZ PLZ help to debug it !
[22:23:36] <Ziegler> what size are the steppers?
[22:23:50] <Ito-Brazil> NEMA23 1,2A / 6V
[22:24:04] <Ito-Brazil> with 6:1 reduction
[22:24:48] <Ziegler> oz-in ?
[22:25:04] <Ito-Brazil> hm.... 6 kg/cm2 ?
[22:25:06] <Ziegler> how fast are you running them
[22:25:18] <Ziegler> cm 2?
[22:25:28] <Ito-Brazil> well ... i started with 40 mm max speed
[22:25:39] <Ito-Brazil> it ran OK on ther CNC (small)
[22:25:41] <Ziegler> does it loose steps at that spped
[22:25:56] <Ziegler> speed
[22:26:12] <Ito-Brazil> running just one axis, no
[22:26:27] <Ito-Brazil> running X and Y (circle) it looses
[22:26:46] <Ziegler> ahh
[22:26:53] <Ziegler> how large is the power supply?
[22:26:59] <Ziegler> watts ?
[22:27:08] <Ziegler> voltage ?
[22:27:26] <Ito-Brazil> 60V / 10A same as the small cnc
[22:27:40] <Ito-Brazil> is like a clone from the other electronics
[22:27:51] <Ito-Brazil> the small one runs very fast
[22:28:26] <Ito-Brazil> http://www.linuxcnc.org/component/option,com_mospjirc/Itemid,8/lang,en/
[22:28:32] <Ito-Brazil> take a look
[22:28:48] <Ziegler> so you ran the steppers on the other machine?
[22:29:10] <Ito-Brazil> i lowed all speeds, but the problem get bigger at low speeds
[22:29:25] <Ito-Brazil> i changed the X axis stepper 3 times
[22:30:40] <Ziegler> what is that?
[22:30:54] <Ziegler> the application?
[22:31:26] <Ito-Brazil> MDF cuts, acrilic, plastics
[22:32:12] <Ziegler> that link you sent me takes me to a page to download some application
[22:32:17] <anonimasu> sounds like you run out of cream(power)
[22:32:32] <anonimasu> does it happen when you jog one axis?
[22:32:37] <Ziegler> that was my guess too but he says its a twin
[22:32:49] <anonimasu> twin?
[22:32:59] <Ziegler> clone of another machine that works fine
[22:33:09] <anonimasu> Ziegler: well, then it might be flex..
[22:33:39] <Ziegler> hey... does anyone know... if the double speed change has made it to ubuntu package yet?
[22:33:51] <anonimasu> Ziegler: one axis causes the other one to bind and draw too much current..
[22:33:58] <Ito-Brazil> FLEX ?
[22:34:04] <Ziegler> makes sense to me anonimasu
[22:34:08] <anonimasu> yep
[22:34:52] <Ito-Brazil> hm are ya saying the power supp could be the problem ?
[22:35:06] <anonimasu> Ito-Brazil: measure how much current you draw..
[22:35:29] <Ziegler> partly... but he is saying one stepper might be binding due to flex of the gantry
[22:35:42] <Ziegler> Ito-Brazil: that link you posted before is a link to the irc chat
[22:37:04] <Ito-Brazil> flex of the gantry... plz explain that, sorry my bad english
[22:37:26] <Ito-Brazil> that´s a TUX milling from the small CNC
[22:37:28] <toast> the thing bends
[22:37:32] <toast> under force
[22:37:43] <Ito-Brazil> hm
[22:37:47] <archivist> causing friction
[22:37:57] <Ito-Brazil> torcion
[22:38:03] <archivist> also look for resonance
[22:38:15] <archivist> vibration
[22:38:26] <toast> what archivist is saying is that the bent part of the mill puts the shaft out of alignment
[22:38:35] <toast> and it consumes a ton more power to turn when it is that way
[22:39:15] <archivist> resonance/vibration causes lost steps
[22:39:23] <archivist> as well
[22:39:26] <toast> indeed
[22:39:37] <anonimasu> anonimasu has changed the topic to: tomp
[22:39:37] <ChanServ> ChanServ has changed the topic to: Welcome! EMC (Enhanced Machine Controller) is a linux-based opensource CNC control. | Latest release: EMC 2.1.7 | http://www.linuxcnc.org | http://wiki.linuxcnc.org
[22:39:52] <archivist> noise will increase at worst speed
[22:40:03] <Ito-Brazil> yes i can imagine some how
[22:40:21] <anonimasu> also if something can move it might cause resonance too..
[22:41:09] <anonimasu> however that's probably not the case..
[22:41:15] <toast> toast is now known as toastydeath
[22:42:24] <Ito-Brazil> could be a twist
[22:42:45] <Ito-Brazil> my X axis is not a hard mechnical stuf
[22:42:53] <fenn> steppers consume more power at slow speeds because there's less voltage generated in the motor
[22:43:35] <fenn> i would start with power supply stuff
[22:43:43] <anonimasu> agreed
[22:43:55] <anonimasu> though if he has the same setup on another machine that's identical..
[22:43:55] <anonimasu> :)
[22:43:56] <fenn> especially if you get the problem when more than one motor is running
[22:45:11] <Ito-Brazil> Yes a teacher of mine said same thing about power supply
[22:45:21] <anonimasu> stick a meter on it.
[22:45:24] <toastydeath> side question: who in here is vegitarian
[22:45:36] <Ito-Brazil> i already have a voltmeter
[22:45:46] <Ito-Brazil> 52V all the time
[22:45:49] <anonimasu> measure current..
[22:46:16] <Ito-Brazil> If i have low transformer, it means like the voltage downs, right ?
[22:46:21] <Ito-Brazil> oke
[22:46:38] <anonimasu> and make sure you have a fused meter..
[22:46:39] <anonimasu> :)
[22:46:44] <Ito-Brazil> Professor Nailson Roveta said that once
[22:47:00] <Ito-Brazil> i will try this today
[22:47:12] <anonimasu> im not too sure you will see a voltage drop..
[22:47:25] <Ito-Brazil> thank you all guys, nice to see ya again thanks for teachings
[22:47:35] <anonimasu> once the stepper starts losing steps, it starts to draw less current..
[22:47:48] <anonimasu> as it dosent move the gantry..
[22:47:50] <Ito-Brazil> i will dinning now
[22:48:17] <Ito-Brazil> yes i got your point, anonimasu !
[22:48:30] <Ito-Brazil> Current meters, here we go!
[22:48:37] <anonimasu> laters
[22:49:00] <Ito-Brazil> Thank you Ziegler, Fenn, Anonimazu!
[22:49:09] <Ito-Brazil> i will be back with results later!
[22:50:00] <toastydeath> vegitarians? vegans?
[22:50:01] <toastydeath> anywhere?
[22:51:35] <anonimasu> if it makes you upset yes.. if not then no..
[22:51:35] <anonimasu> :p
[22:52:42] <toastydeath> no, i had a question
[22:52:44] <toastydeath> about a cookbook
[22:52:50] <toastydeath> nothing controversial
[22:52:55] <toastydeath> unless you have something against cookbooks
[22:53:14] <anonimasu> oh sorry :/
[22:53:21] <dmessier> hi all
[22:56:54] <mgouget> hello!
[22:59:22] <jlmjvm> hello mgouget
[23:00:24] <jlmjvm> your machining druid looks good
[23:00:54] <mgouget> jlmjvm: Thanks
[23:01:39] <mgouget> jlmjvm: Have you tried it?
[23:02:51] <jlmjvm> havent had time yet,working on a retrofit that should finish up tomorrow,but wanna try it this weekend
[23:03:34] <fenn> toastydeath: i've been 96% vegan for about 4 years now
[23:03:59] <fenn> imho vegan cookbooks all suck
[23:04:55] <jlmjvm> i have some friends that use mach3 that wont change to emc because they use the wizards everyday,but this looks promising
[23:05:03] <toastydeath> fenn:
[23:05:22] <mgouget> jlmjvm: if you want to get a feel, just execute the standalone binary: http://www.gouget.org/druids/download/dsurfsa which should work as-is on any linux
[23:05:28] <toastydeath> dude at work is trying to go veggie, and i had a friend at one point who liked a certain fast food vegitarian cookbook
[23:05:36] <toastydeath> which is apparently a popular vegitarian fast food cookbook
[23:06:01] <toastydeath> and i am hoping that any arbitrary vegitarian or vegan will know what i am talking about
[23:07:15] <fenn> uh, not really. google directs me here http://www.amazon.com/Vegetarian-Fast-Food-Delicious-Minutes/dp/0679762078
[23:07:24] <toastydeath> hmm
[23:07:28] <toastydeath> perhaps
[23:08:59] <fenn> i better stop drawing this mazak or it'll never be done
[23:09:32] <toastydeath> h..how does that work
[23:09:39] <fenn> http://fenn.dyndns.org/pub/sketches/emc-splash/mazak.png
[23:09:39] <toastydeath> if you don't stop doing something it will never be done>
[23:09:40] <toastydeath> ?
[23:09:50] <fenn> yep that's usually how it goes
[23:09:51] <toastydeath> that's some philosophical crap, that right there
[23:09:57] <toastydeath> also nice mill
[23:10:27] <jlmjvm> mgouget:downloaded that file to my desktop,wont open
[23:11:02] <mgouget> jlmjvm: try a chmod 755 on it...
[23:15:56] <jlmjvm> had to change the properties to execute
[23:17:56] <mgouget> jlmjvm: and so?
[23:18:51] <Ziegler> hmm.... my physical estop is working the exact opposite from what I would like. How do I invert the pin... this is what I have: linkpp parport.0.pin-10-in iocontrol.0.emc-enable-in
[23:21:12] <Ziegler> I tried: linkpp parport.0.pin-10-invert-in iocontrol.0.emc-enable-in
[23:21:30] <Ziegler> oops
[23:21:41] <Ziegler> linkpp parport.0.pin-10-in-invert iocontrol.0.emc-enable-in
[23:22:28] <Ziegler> And another question... why doesnt e-stop stop the spindle also?
[23:25:21] <toastydeath> a very good question.
[23:25:45] <jlmjvm> mgouget:wow
[23:26:19] <cradek> Ziegler: what emc version?
[23:26:57] <Ziegler> ehh... um whatever was in the latest ubuntu pack
[23:27:04] <Ziegler> as of last night
[23:27:28] <mgouget> jlmjvm: I am trying to create a framework for creating druids, with a nice UI and direct access to EMC
[23:27:50] <Ziegler> Does the latest version have the "speed" updates that ease up on the processing?
[23:29:12] <jlmjvm> mgouget:its very impressive
[23:30:26] <Ziegler> those might still be cvs... I think that was only a couple weeks ago
[23:34:18] <Ziegler> cradek: is emc-enable-in the right thing to use?
[23:38:42] <jlmjvm> i have a parport setup and my emc-enable-in is commented out
[23:40:09] <Ziegler> do you have a physical estop button?
[23:40:10] <jlmjvm> http://pastebin.ca/724927
[23:40:15] <jlmjvm> yes
[23:40:34] <jlmjvm> alex_joni gave me this when i set mine up
[23:40:39] <Ziegler> ahh
[23:40:40] <Ziegler> ok
[23:41:21] <Ziegler> alright let go give that a whirl
[23:41:31] <jlmjvm> and you can change your button by using 10-in-not
[23:42:07] <Ziegler> instead of invert?
[23:42:12] <jlmjvm> yes
[23:42:19] <Ziegler> is invert the old way?
[23:42:54] <Ziegler> thanks jlmjvm... ill give this a try an be back in a bit
[23:42:58] <jlmjvm> that i dont know,but my limit switches are in-not
[23:43:11] <jlmjvm> k
[23:53:05] <jlmjvm> Ziegler:the in-not doesnt change my button
