If you wanted to extrude 35 mm of plastic (which is a lot), it would be G1 E35 F225adamcooks wrote:theres a line in the start gcode that calls for priming
mine says "G4 P3500 ; purge nozzle" i just put a semi colon in front of it and it stopped that
Like KeyboardWarrior said, the G1 E15 F225 will do an initial 15mm extrusion of filament if you put it in the starting G-Code. For PrintrBot Simple, or printers with an auto-bed leveling probe, I would suggest this for a starting G-Code Script to home, probe, and purge correctly:KeyboardWarrior wrote:
