  1. Hi all! Recently I was trying to mount a E3D hotend onto the UM2, which means PID tuning is needed. Yet I have trouble implementing the "M303" command for PID auto tune. I typed in "M303 C8 S175" on notepad, saved it as .GCODE on a SD card and tried to run the file with the "Print" option with UM2. But the printer would not execute the command and only shows "print finished" at the end. So apparently I am doing it wrong, but is there any other way by which I could implement a gcode on UM2? If yes, how? Sincerely Nicholas
