Hey All,
I recently replaced my extruder head and it required a change in the extruder motor direction. So I swapped the wires for the stepper motor to change the polarity of a coil and now the extruder just jitters instead of working.
If I plug the extruder motor into the x-axis and jog it, it runs fine. Now I know that swapping wires on the stepper motors isn't supposed to be able to damage the board, but I think that in this case it has. Any ideas about how to work out what's blown? Is it the stepper driver?
Also note: the heatbed now powers on when I switch on the power supply and won't respond to temperature controls. Not sure if this is related but it was fine before I tried to reverse the stepper direction.
