I used to do this all the time with a DC motor using gen3 electronics and makerbot firmware 3.0.
I would heat the head, extrude to prime the tip, Home, then turn on the motor with a M101 Extruder on, fwd command and a speed command of M108 S255 extruder speed.
I have been unsuccessful with my Stepper motor. It seems when the extruder is turning it wont go to the next command.
I want to print a trail to the part so the tip is primed and ready to go for the first line.
I am using ReplicatorG, RAMPS 1.4, Marlin firmware, Stepper exruder, Skenforge 40.
Thanks
