I have an Anilam 3300mk on a 1998 HH Roberts bed mill. After months of trouble free service I am getting a "Z lag error" when I try to home the mill. If I try to move the bed I get the same error for that axis. The servos turn easily and the bed moves freely. The drive belts are in good shape and I cleaned the servo connections. The controller boots up normally. What should I do next? (Before I call in the service guy.)
Thanks in advance
Matt
