Tom,
I set the parameters, and now the A axis is working fine.
So I tried running some g code - just a simple cube.
Using KMotionCNC, the X & Z axis work as expected (axis 0 & 2). The Y axis (axis 1) tries to move, and shuts down. However, it works as expected in KMotion.
Even weirder, though, is that a G1 Y1 or G1 Y0.1 cause this shut down, but if the axis has moved, a G1 Y0 does NOT cause the error, and it moves back to 0.
How can I tell what is going on here?

Thanks,
Michael
