Description
Its semi-automatic - filament is cutting with gcode (move head to position). Also is possible cut filament manually by hand. If you have original riser from flashforge (or printed) i recommend using short version of cutting arm. It is designed for maximum use of the printing area.
If you dont have the riser, you can use long version of cutting arm. otherwise (riser with long arm) the filament will be cut if you print in the area near the riser on this side.
Just put these lines to gcode, where you need cut filament (change filament gcode):
G0 Y-90 X-100 F6000 G0 Y-105 X-100 F2000G0 Y-105 X-80 F6000
On pictures is position of block which make press to cutting arm.
