Gcode for material retraction and print end

Postby 3d4you » Wed Jun 07, 2017 8:24 pm

I would like to make the Printer retract the material after print Job in order to not clog the nozzle and to make filament changes easier. Could this be done via gcode commands at the end of the print Job? If yes, what command should be used?
