Scratches do not necessarily mean bad! Usually the forcer motor fails before a platen. The motors become weak or don't evenly distribute the supplied air, which causes them to tilt and drive into the platens. Mechanical misalignment of the VY forcer

Sorry I didn't catch your message sooner! 20k is way to much. The odds of you having 3 bad platens and 3 bad forcer motors would be very unlikely, unless the machine was sitting outside or something. If it is a 10 year old AP then I assume it must

Don, either you have a faulty park sensor or much more likely the vision gantry Y axis is not reaching the sensor. Possible issues, one of the two VY drivers cards is failing; one of the VY forcer motors (air bearings) is failing; to much air leakin

Daxman, The diagnostic results didn't look very pretty. Especially on the vision x standard deviation. Any time there is an asterisk, that is a bad thing. The failure number for all axis, excetp theta, is .0002. Could need more air flow to the x

Giao, These style of MPM's use stepper motors, but no feedback like an encoder or a resolver. In other words all axis positions are assumed after "Reset" of the machine. Because of this style of drive system there is the potential for the vision ga
