The latest Tiny Machines firmware (2.0) supports M600, but I'm having a devil of a time trying to get the M600 command to function.
Basically, when the M600 command is sent to the printer, it appears that Octoprint misses one of the return prompts and at that point everything gets jumbled in trying to hand off additional commands to the printer for stepping through the filament change.
Was wondering if anyone is running Octoprint with a Creality printer and able to do a programmed filament change?
