I bought an old BMC30, with ultimax II V8.61. It give me a massege: Servo fault in Z This massage come, when I try to move the z in the manual mode. I try an other dual axis bord (a good board), but the massege is remain. When I plug the z axis to the x chanel, than it can move. I think that the cables and encoder and servopack work correctly.
What could be the problem?
