[01:35:01] <undrill> probably off-topic, but does anyone know how these pegboards work?
http://www.machines4u.com.au/view/?advert_id=1220&photo_id=2641
[01:35:38] <undrill> very little info on the net
[01:48:48] <undrill> ah, here's a better pic:

[01:50:02] <tom3p> re: pegboard... looks like what i had on a very early agie cnc sinker. the pins are diodes, you 'program' a big diodes array and sequence thru the rows.
[01:50:41] <undrill> tom3p, ah, so it's sort of a pre-cnc thing
[01:50:46] <tom3p> the diodes allowed differnt things to happen on each row. the row was incremented by arriving at differnt positions ( using encoder feedback )
[01:51:15] <tom3p> the diodes could change rpm, flush, current , etc
[01:51:18] <undrill> I saw one yesterday, and there didn't look like enough space to program anything useful
[01:51:21] <tom3p> not neccesarily, just when i encountered it
[01:51:41] <tom3p> haha those were days of 128x8 eproms! (and smaller!)
[01:52:25] <undrill> be nice if the lathe could be converted to something more modern
[01:52:35] <tom3p> if you run into a user of an AGieMAT3, he'll sell his soul for a handful of diodes ;)
[01:52:37] <undrill> probably more trouble than it's worth
[01:53:01] <tom3p> oh, it programmed a c axis and a tool changer too
[01:53:36] <undrill> yeah, there was a 6 hole turret
[01:54:12] <undrill> and a bar feeder could be fitted
[01:57:50] <undrill> tom3p, thanks for that info
[02:48:01] <tom3p> cool, the emc diagram at
http://wiki.linuxcnc.org/uploads/emcmot03.svg can be zoomed by ctrl-mousescroll-up
[02:48:26] <tom3p> firefox still cant pan svgs, but i was surprized the zoom worked
[03:01:39] <Stinger> why can't it pan?
[03:04:02] <tom3p> svg sez pan is ctl right btn and that doesnt pan ( maybe gnome eats it , scuza )
[03:09:56] <tom3p> is this true?
[03:09:56] <tom3p> inverse kinematics solves this... 'if you were at this position, in this pose, where would each of your axis/joints be?"
[03:09:56] <tom3p> forward kinematics solves this... 'if your joints/axis were this way, where would you be & what would your 'pose' be?"

[13:46:03] <tom3p> is this true?

[13:58:14] <issy> hi all
[14:01:20] <anonimasu> tom3p: yeah
[14:17:31] <tom3p> anonimasu: thx
[14:17:47] <anonimasu> think of it as a chain of links leading to a effector position
[14:18:01] <anonimasu> and forward or reverse as the direction you are solving for
[14:18:17] <anonimasu> tom3p: doing robotics?
[14:23:09] <tom3p> anonimasu: no, trying to make my way thru the emc code. i'd like to use HAL to do EDM, and dont want to chuck the whole EMC side.
[14:24:13] <anonimasu> ah, I see
[14:24:34] <tom3p> after the gui talks to the intrepreter, who puts nml msgs for line & circle onto some nebulous stack/queue, i gets lost in a swamp
[14:25:41] <anonimasu> * anonimasu nods
[14:26:14] <anonimasu> im spending my morning waiting for someone and studing math :)
[14:31:20] <tom3p> classical music in background : good for studying math ( maybe urban legend , i just heard it someplace )
[15:13:58] <tom3p> is traj_period_nsec the same as servo_period_nsec ?? they seem to be equated in motion.c. if they have the same frequency, do they update/sample at same time?
[15:16:00] <tom3p> seems like it might be nice to look at the horse after it ran a bit, rather than right out of the gate.
