I have a Replicator Dual, wooden frame. I only have one stepper installed at a time, the right stepper. I had the setting on the actual printer set to "Single".

Anyway, the communicator cable to the right stepper was shorting out, so I removed the right stepper and installed the left stepper, and then I set the printer to "Dual".

I can successfully load filament , but when I home the print head, I get a horrible clicking sound, it appears as if my extruders/steppers are off center.

Any thoughts how to fix this?
