Not sure if this is the right forum but I have a machine similar to a Miltronics with a centurion 7 control. It trips the Y drive after about an hours use and comes up with a code on the dive A.72. Does anyone know what this means? The Y axis motor is getting hot, it was changed with a new one with no difference, the drive cables X and Y have been swapped over and the parameters changed accordingly but the fault still remains on the Y axis. If I don't get this sorted soon I'm in big trouble.
check your gib clearance in the Y axis it sounds to tight causing it to bind.
