I am printing for years with octoprint and sliced with cura. In cura there is an option with says "switch on printer with: PSU control". When I started a print job Octoprint automaticaly switched the printer on and started the print job. Now I switched to orca slicer which is much better in my opinion. Unfortunately there is no such option in orca slicer. What is cura doing to switch on my printer via GPIO pin? Can I do the same with orca slicer?
I've seen it and tried it but unfortunately it doesn't work. M80 is a gcode that is sent to the printer, but it is not switched on at the time and so has no effect. I also tried M81 as the end code and that works and the printer turns off. There has to be some command to the raspberry pi.
