I don't understand how I can send the M80 gcode to the PSU Control plugin if there is no connection to the printer board, because it is powered off.
The Terminal is inactive and you can't send any gcode files.
I know that it would work if I would power the board with 5V instead of 24V, but this is no option for me.
The board of my X5SA is not powered by 5V. The BTT SKR 1.3 would allow me to power the board with 5V, but this would kill my TMC drivers. These drivers get power from the 24V and they don't like that their signal pins get 5V if the 24V is off.look here
So the only option I have is the toggle button?
