Reversing extruder motor rotation

How do I reverse the rotation of my extruder motors? I have a HE3D EI3 printer using .92.8 firmware. Both of the stepper motors are running the wrong direction. Is there a command to reverse the motor rotation?

Thanks, Ed


  • Either rotate motor connector 180° whcih is inversion of direction, or recompile firmware with invert direction flag for that extruder toggled.
