[00:07:34] <Valen> hooters santa you say
[00:07:42] <Valen> might need to inspect this
[00:10:31] <frysteev> any hal gurus online?
[00:11:10] <jthornton> sure
[00:11:14] <r00t4rd3d> jdh say what? You do realize what xmas represents right??
[00:12:07] <jthornton> buying useless gifts!
[00:12:45] <frysteev> im working on rebuilding a robot arm, there is a resolver digitizer, that outputs quare waves, i could technically dump that into emc, and program it to decipher the signal right?
[00:16:06] <markvandenborre> anyone around here has experience with excitech cnc routers?

[00:17:38] <markvandenborre> they seem to get relatively good reviews for a Chinese machine
[00:24:44] <pcw_home> frysteev: if these square waves are quadrature, LInuxCNC can use those directly
[00:27:28] <frysteev> well no
[00:27:43] <frysteev> it converts the resolvers waves to square waves
[00:28:04] <frysteev> im probably going to end up with the mesa card, im just curious
[00:29:30] <pcw_home> There are resolver to quadrature converters
[00:29:32] <pcw_home> how do the square waves convey position?

[00:30:06] -!- bedah has quit [Quit: bye]
[00:30:18] <frysteev> the square waves are just direct conversions of the sine waves
[00:30:46] <frysteev> you would essentially do the resolver to quadrature logic in hal
[00:32:31] <pcw_home> Hmm does not sound like a resolver to me (resolver position information is conveyed in the relative amplitudes of 2 AC signals)
[00:33:30] <frysteev> amplitude does change in the wave, only the phase of it
[00:35:31] <pcw_home> Ahh thats the reverse of a resolver
[00:36:54] <frysteev> i figured tho if ts all a]]
[00:37:07] <frysteev> square waves, tat emc should be able to do it no?
[00:43:20] <pcw_home> maybe but it would need to be taught to measure the phase difference between the reference and position signals
[00:43:51] <frysteev> mesa card it is then :P
[00:44:23] <frysteev> has anyone done any teach functions with emc?
[00:44:43] <frysteev> with my existing robot arm controled it will record a manual bath,
[00:46:10] <pcw_home> Inductosyn thats the word I was thinking of...

[00:47:13] <frysteev> ?
[00:48:21] <pcw_home> Your device (reverse resolver) sounds like an inductosyn
[00:50:18] <frysteev> well its an old asea irb6,
[00:50:42] <frysteev> the only thing ill be saving is the analog servo drives,
[00:51:41] <pcw_home> a resolver takes a single AC source and outputs 2 ac signals of varying amplitudes
[00:51:43] <pcw_home> an inductosyn takes a sine and a cosine input waveform and outputs a constant amplitude sine wave of varying phase relative to the drive
[00:52:08] <frysteev> yes
[00:52:34] <frysteev> exactly,
[00:52:51] <frysteev> is that easier or harder to interface,
[00:53:17] <frysteev> someone told me that the resolver is the same, and i could drive it like a typical resolver,
[00:54:32] <pcw_home> I suspect the inductosyn is easier to interface (all digital except the drive circuits)
[00:55:06] <pcw_home> except theres no current interface of that type in HostMot2
[00:55:25] <frysteev> but could i take it right into emc and figure it out in there?
[00:56:06] <pcw_home> Yes its just a matter of counting time from one edge to another
[00:56:55] <frysteev> i would have a sine and cosine ref erence in for all drives, then one ref for each axis i believe?
[00:57:19] <pcw_home> Yes
[00:57:44] <pcw_home> Do you have any of the original interface circuitry?
[00:57:55] <frysteev> i have it all in stock form
[00:58:04] <frysteev> waiting on the service manual to arrive in the mail
[00:58:39] <pcw_home> A lot of that may be re-usable

[00:58:57] <frysteev> well te servo drives are for sure,
[00:59:17] <frysteev> can you drive inductosyn in reverse as a typical resolver?
[00:59:37] <frysteev> is it basically just a differnt way to excite it?
[01:01:45] <pcw_home> Maybe but normally inductosyns are much higher frequency and many cycles per turn
[01:02:19] <frysteev> well the documentation refers to them ass resolvers

http://gnipsel.com/linuxcnc/gui/gui08a.html
[14:06:38] <archivist> Gremlin is the python equivalent to what the Axis GUI uses. "what"
[14:07:42] <archivist> what-> graphics window or something
[14:07:52] <jthornton> working on it
[14:08:01] -!- sumpfralle has quit [Ping timeout: 246 seconds]
[14:09:33] <jthornton> do a refresh and see if it makes any sense now... I just wrote it and have not read it :)
[14:11:29] <archivist> you still dont say what it is, you say its a equivalent to something another gui used to show a plot
[14:12:19] <jthornton> help me out
[14:13:11] <archivist> I would be guessing as I have not looked at exactly what gremlin does for the user
[14:16:24] <jthornton> I don't know how to explain it better...
[14:16:49] <archivist> is it an opengl graphics window
[14:17:28] <jthornton> I don't know, I'll see if I can see any clues in the gremlin.py file

[14:20:25] -!- mhaberler has quit [Quit: mhaberler]
[14:20:55] <archivist> so it is not obvious to me why you use that over the one axis used, I dont see a differentiation

[14:22:53] -!- psha[work] has quit [Quit: Lost terminal]
[14:22:57] <archivist> I thought axis itself was python

[14:30:19] <jdh> gremlin is also tcl?
[14:33:25] <jthornton> no it is python
[14:41:16] <jthornton> with gremlin and the python interface you can create a gtk python GUI from scratch
[14:43:29] <jthornton> Axis seems to be a mix of python and tcl and other stuff
[14:45:20] <awallin_> axis.py isn't exactly easy to read.. I tried once or twice
[14:45:55] <jthornton> I tried several times to read it

[15:39:57] <jdh> axis is python/tcl, gremlin and friends are python/pygtk

[15:40:04] <JT-Shop> don't look too bad, a bit of facia and a little straighening up
[15:40:44] <jdh> err.. python/tk
[15:40:50] <JT-Shop> and some magic I think
[15:40:58] <jdh> magic is often helpful
[15:41:05] <JT-Shop> somehow tcl plays a part I think
[15:42:28] <JT-Shop> I know ngcgui is tcl and it plays nice with Axis
[15:44:16] <JT-Shop> but, I've been told that you can't use ngcgui with a python gtk GUI
[15:44:56] <JT-Shop> here is a line from axis.py nf.source_lib_tcl(root_window,"axis.tcl")
[15:45:10] <jdh> oh
[15:46:36] <JT-Shop> the calibrate window is tcl as well as hal show and pickconfig
[15:46:42] <JT-Shop> and others
[15:47:13] <JT-Shop> now make my ELO USB touch screen work!

[18:19:18] <JT-Shop> hmm I set up an ELO usb touch screen on the BP mill following the instructions here
https://help.ubuntu.com/community/EloTouchScreen
[18:19:43] <JT-Shop> trying to set another one up on a different computer and the touch does not work but lsusb shows the touch screen
[18:21:01] <Tom_itx> different stages of OS updates?
[18:21:58] <JT-Shop> should be identical OS
[18:23:23] <JT-Shop> guess I'
[18:23:38] <JT-Shop> ll try a hardware swap after while when I get done making parts
[18:24:24] <Tom_itx> would be my next suggestion :)
[18:26:30] <JT-Shop> I did figure out this one has APR touch technology
[18:27:52] <JT-Shop> LOL the latest ELO Ubuntu driver is for 8.04

[21:23:05] <gene__> Q: I have a loadrt lowpass module setp'd to a gain of 8, input is around +2.5, is addf'd to servo thread, but output is -nan???

[21:29:38] <cradek> gene__: you may have to load an initial value by toggling the load pin
[21:30:10] <cradek> it looks like lowpass doesn't have an initial state that's forced to make sense otherwise
[21:32:05] <gene__> On restart, the output is 0 before I move the spindle, move the spindle and it goes to -nan, and the pointer of the tachometer I just made in pyvcp disappears. I didn't have to toggle it 2 weeks ago.
[21:32:33] <gene__> lemme setp the load pin to true just for S&G, BRB
[21:32:50] <cradek> well if it's how you describe, it's not an initial state problem
[21:33:36] <gene__> setp true, its following, apparently in real time
[21:34:31] <cradek> once you feed it a nan, ever, it will stick that way, unless you load a new value
[21:34:50] <gene__> back to false and its out in the south 40 someplace called -nan
[21:34:55] <cradek> because the past is always averaged in, and a single drop of nan is enough to always give you a nan
[21:35:49] <cradek> so your problem is probably before the lowpass input
[21:36:34] <gene__> so what good is a lowpass that doesn't pass? The spindle is currently turning at about 2.8 rps
[21:36:50] <gene__> the lowpass input is encoder.0.velocity

[21:44:29] <cradek> not sure I understand what you are asking. if you have load stuck true, I agree it's no use
[21:44:59] <cradek> hmm is encoder.0 a software encoder component?
[21:45:21] <cradek> if so, it smells like it sometimes gives you nan velocity for some reason
[21:46:02] <gene__> I just ran the spindle up to about 19 rps, and I see a very small reading on the tach, roughly corresponds to the rps from the encoder which is showing 19.5 approx
[21:46:48] -!- plushy has quit [Quit: Leaving.]
[21:47:01] <gene__> And I must have a heck of a lot of Igain "windup"
[21:49:40] <gene__> So, I need to switch to another instance of limit2 for filtering, and add yet another scale for some gain. And nuke 99% of the pid.0.Igain, back when I've done that
