[00:17:55] <Tom_itx> i wonder if i can figure out spindle sync tonight
[00:18:02] <Tom_itx> the pieces are all in place
[00:18:10] <Tom_itx> the code needs some work

[00:53:41] <Tom_itx> http://linuxcnc.org/docs/2.7/html/examples/spindle.html#_spindle_synchronized_motion_a_id_sec_spindle_synchronized_motion_a
[00:54:13] <Tom_itx> in the spindle at speed example, where do the spindle-cmd and spindle-velocity signals come from?
[00:54:46] <Tom_itx> those appear to be output to the near function so must contain values
[00:55:28] <Tom_itx> and i don't see them in motion.spindle.xxx
[01:03:24] -!- CaptHindsight has quit [Quit: gone]
[01:10:55] <seb_kuzminsky> it's motion.spindle-at-speed
[01:11:01] <seb_kuzminsky> Tom_itx:
http://linuxcnc.org/docs/2.7/html/man/man9/motion.9.html
[01:11:10] <seb_kuzminsky> motion.spindle-at-speed IN BIT
[01:11:10] <seb_kuzminsky> Motion will pause until this pin is TRUE, under the following conditions: before the first feed move after each spindle start or speed change; before the start of every chain of spindle-synchronized moves; and if in CSS mode, at every rapid->feed transition.
[01:11:49] <Tom_itx> i'm looking at the motion page too
[01:12:16] <Tom_itx> i'm wondering where those input signals come from
[01:13:05] <Tom_itx> i started this about a month ago and had to let it sit :(
[01:13:59] ffurrywol is now known as furrywolf
[01:16:08] <Tom_itx> i temporarily had that pin hardcoded true
[01:16:23] <Tom_itx> i'm trying to get it from the spindle now
[01:17:29] -!- asdfasd has quit [Ping timeout: 256 seconds]
[01:17:38] <seb_kuzminsky> it comes from your spindle feedback mumble, vfd or encoder or whatever
[01:18:27] <Tom_itx> so that's a sudo example
[01:18:33] <Tom_itx> not actual working code
[01:19:23] <seb_kuzminsky> it's meant to be working
[01:19:36] <seb_kuzminsky> in 6.1 we see the spindle feedback coming from an encoder comp
[01:19:57] <seb_kuzminsky> in 6.2 we add a near comp to tell motion when the spindle is "at" speed (really: near speed)
[01:20:30] <Tom_itx> ok i wasn't following from the top, i started at 6.2
[01:20:36] <Tom_itx> i'll review it again
[01:20:45] <seb_kuzminsky> yeah, 6.2 isn't a complete example, but 6 is ;-)
[01:21:10] <Tom_itx> do i need the sync example for rigid tapping?
[01:21:12] <Tom_itx> i suppose so
[01:22:34] <seb_kuzminsky> i dont understand the question
[01:23:09] <Tom_itx> i need the signals for synchronized motion for rigid tapping to work properly
[01:23:10] <seb_kuzminsky> spindle synced motion like rigid tapping requires spindle feedback
[01:23:16] <Tom_itx> ok
[01:23:46] <seb_kuzminsky> rigid tapping works on the spindle index, i think (like in the example in 6.1)
[01:24:02] <Tom_itx> for some reason andy's gear cutting youtube keeps sticking in my head
[01:24:17] <seb_kuzminsky> so you need a one-pulse-per-rev signal from your spindle feedback circuitry to trigid tap
[01:24:24] <seb_kuzminsky> well andy's a wizard
[01:24:28] <Tom_itx> where do you reset the index signal or is that part of the rigid tap cycle?
[01:24:28] -!- CaptHindsight [CaptHindsight!~2020@unaffiliated/capthindsight] has joined #linuxcnc-devel
[01:24:42] <Tom_itx> i realize you need to reset it once it's triggered
[01:25:02] <Tom_itx> i think that's one of the few bidirectional pins
[01:26:15] <Tom_itx> i should be asking in the regular channel... it's kinda gone to crap lately
[01:37:01] <Tom_itx> i did get 2.7 loaded

[02:17:52] <Tom_itx> crap. motion.spindle-speed-in is in rps and motion-spindle-speed-out is in rpm
[02:18:00] <Tom_itx> one would think they would be in the same units
[02:18:10] <cradek> there's like 11 outs in different formats
[02:18:17] <cradek> pick the appropriate one
[02:18:36] <Tom_itx> ty
[02:18:38] <Tom_itx> :)
[02:18:54] <Tom_itx> -out-rps
[02:19:10] <Tom_itx> and probably abs
[02:19:20] <Tom_itx> since it will be reading reverse as well
[02:30:00] <Tom_itx> nope, abs not needed
[02:30:08] <Tom_itx> thanks cradek it's working
[02:30:26] <cradek> yay!
[02:30:31] <Tom_itx> now on to the sync part...

[02:42:22] <Tom_itx> ok i mdi the G33.1 command and it moved z with the spindle however it never stopped and reversed out
[02:42:37] <Tom_itx> (nothing hooked up, just watching the screen)
[02:52:35] <Tom_itx> mmm watching it, the scale somewhere seems way off. it's moving in -z but the distance to go is taking forever to count down using the .750" thread from the example
[02:52:59] <Tom_itx> it probably would have cut about 6-8" worth by now
[03:00:18] <Tom_itx> i think i need to find the component that scales the spindle rpm with the stepper pwm
