Posted · Problem with Extrusion

Recently I have had some problems with my printer. The extrusion motor doesn't turn. The motor is fine (I hooked it up to another power source), the connections to the motor are all working, but the motor doesn't turn. Any Tips?

    Your printer probably has some variant of Marlin firmware which by default disables the extruder if the hot end is below some temperature (e.g. 160C).  Maybe you need to "allow cold extrudes" with an M302 gcode command.
