I had 4 of these machines. They are good machines but I have seen this error often. Is the problem only on one head L or R? If so swap electronics L to R and see if it follows. You can even swap the Y motors. The items that could cause this prob

I'm trying to visualize how that machine is laid out. Do they all rotate together, on a belt, so that there's only one sensor for the theta (R) home position?

It sounds like the homing switch isn't being made when it zeros. Alpha 1 Technologies can probably help. 607-772-2900 That's who we call for VCD issues.
