Job doesn't start if the printer is off.

[Gleb1982]

Hi, I using a PSU plugin and am turning printer off when it's idle for 15 minutes. PSU is set to trigger the printer by a system command "gpio write 2 0" and to automatically connect after power on command with a 10 sec delay (for the USB port to appear). Also PSU is listening for M81 and M80 Gcode commands.

PrintScheduler doesn't start the print when the printer is off, I tried to set system command "gpio write 2 0" before print, also tried Gcode M80. Nothing helped.

For example when I start printing from Cura, the printer turns on automatically.

Would be great to have an integration with PSU in this plugin, this should not be hard to do via PSU API.

thanks!

I think it should work with PSU Control. Did you see the wiki examples that in theory are functional. I know the Tasmota one is.

I trued running command from SSH, it didn't change state of PSU. here is what I got on the screen. FYI Am using OrangePi Zero 2

That would be an issue with PSUControl. With that plugin it should work fine on orange pi if I'm not mistaken, but you don't use the Rpi.GPIO module add-on, just use the built in periphery implementation. Once you get that plugin working, then this should work as a system command before. You might need to add users to the dialout rules, etc. I just don't have much experience with GPIO stuff to assist you further. Possibly look into that plugin's repo for assistance or possibly ask in OctoPrint's Discord under the support-plugins channel for someone that may have your specific setup.

I'm having a similar issue where Print Scheduler is not starting jobs when the printer is off. I have commented out lines 36 to 38 to get it to power on the printer and added "/home/pi/oprint/bin/octoprint plugins psucontrol:on && sleep 10" to the System Command Before Each Print section. Seems to have fixed the issue as the lines 36 to 38 pretty much say "do nothing if the printer is off".

[au-mikey]

I also moved the line which runs the system commands to the beginning of the next loop so that the printer can power on before the file is loaded to print

[jneilliii]

I see now. A PR would have been nice...

[jneilliii]

I just pushed the above commit and it will be available as 0.0.4rc1 shortly. Moved the exit logic into the for loop, after the system command being run. This way, at most you would have one repeated timer miss if your command didn't include a sleep and the print job would be picked up on the next cycle.
