12:55 PM KGB-linuxcnc: 03Sebastian Kuzminsky 05master a8df216 06linuxcnc 10debian/changelog Merge remote-tracking branch 'origin/2.7' * 14http://git.linuxcnc.org/?p=linuxcnc.git;a=commitdiff;h=a8df216
01:46 PM seb_kuzminsky: every time i trace through libnml code i get dizzy and have to take a nap
01:49 PM * JT-Shop can't wait for Saturday and a nap
02:08 PM mozmck: What is the Not-Enable I/O pin for in hostmot2 PWMGen?
02:09 PM mozmck: Can/should that be used for spindle on?
02:09 PM seb_kuzminsky: i think it should
02:10 PM seb_kuzminsky: if that pin indicates "enable", then the downstream amp should pay attention to the pwm signal
02:10 PM seb_kuzminsky: if the pin indicates "not enabled", then the downstream amp should power down its motor and ignore the pwm signal
02:10 PM seb_kuzminsky: that's my understanding at least
02:12 PM mozmck: Ok, I'll have to think about that. I wonder if I can define a PWM in the bitfile without that pin.
02:14 PM mozmck: I suppose that if the PWM channel is not used I can use that pin as GPIO?
02:19 PM seb_kuzminsky: if you enable a pwm instance, all that instance's pins are used by pwm
02:19 PM seb_kuzminsky: if you disable a pwm instance, all that instance's pins are used by gpio
02:20 PM seb_kuzminsky: (i mean here, load-time, config-string enable/disable, not run-time setting of the .enable hal pin)
02:20 PM mozmck: thanks, that's what I thought, but couldn't remember for sure.
02:20 PM seb_kuzminsky: all the pwm I/O pins are outputs, so you can't really use them as gpios if the pwm instance is load-time enabled
02:20 PM mozmck: I'm sure it says in the docs somewhere...
02:21 PM seb_kuzminsky: you sound more confident than i feel!
02:21 PM mozmck: Yeah, so if the config doesn't load the pwm instance than I can use it's pins for general outputs.
02:21 PM mozmck: heh!
02:22 PM seb_kuzminsky: that's right
02:22 PM seb_kuzminsky: i got to run, bbl
02:22 PM mozmck: thanks!
03:04 PM skunkworks: jepler, http://electronicsam.com/images/matsuura/20170608_135243.jpg
05:56 PM cradek: skunkworks_: wow
06:26 PM Tom_itx: ok so not everybody prints yodas and more printers with em...
06:26 PM Tom_itx: good stuff skunkworks_
06:34 PM skunkworks_: mostly printing toys for the kids :)
06:34 PM skunkworks_: Although I did print a prototype part for an engine I am building. It took over 24 hours. Drew it in freecad. It went pretty well
06:39 PM jepler: skunkworks_: nice. now i look forward to seeing the 24hr print!
07:14 PM skunkworks_: Well - I hope to have the aluminum version done by then too :)
09:29 PM jepler: hey can someone take a look at https://github.com/LinuxCNC/linuxcnc/pull/279 and merge it if my review request was addressed? cradek or seb_kuzminsky ? thanks!
