Can anybody help?
My SC600 has ceased moving in the x and y direction. I am using WINNCPC with USB and only the Z axis and the 4th axis are responding. When I tell it to go to reference it drives the z axis to the limit switch but then fails to move the x and y axis. I have tried it with two different laptops with the same result. Sometimes I get a "Reference Switch Active" warning when it fails, other times it just sits there. When I do a status check from the WINPCNC menu I see a red light on the 4th/C axis, but am not sure what this is telling me.
This just started happening yesterday after using the 4th axis stepping motor for the first time for rotating a piece and I am stuck. I am thinking maybe I have a stuck switch but I am not sure how to proceed.

Check the wiring. Loose contacts are a very common problem.

I checked the wiring and all connections are tight.
I then swapped the stepping motor connections for the Y and the Z axis. After doing so, the Z axis in the program moves the Y axis and the Z axis now fails to move. I believe this tells me that the stepping motors are good since they move appropriately when driven by the z-axis driver. I also believe this tells me that the problem lies in the circuitry on the StepCraft microstep controller board. There don't seem to be any fusible links I can replace. Any thoughts? I guess I need to replace this board.

Call stepcarft. There has been cases of failure of the driver board.
