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

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

The camera is not driven from the motor cards. The camera is attached to what is called a forcer. For the Y axis there are two of them. One is wired backwards from the other. one of the forcers is connected to a flex chanell for the air and electrica

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

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

When you teach the "teach boardstop Y" make sure the camera is seeing the leading edge of the board and not too close to the rails. It should calculate the pre-stop position correctly. I assume you have thoroughly checked the sensor. Also check th

We are having a problem with our AP-24x printer. When the vacuum motor spins up we get a 60 hz buzz into the DC drivers for the forcers and the stencle wiper. We also indicate a main power drop from 115 vac to 80 vac. The vacuum motor checks out good

I think Sr is right. Miss prints are prolly a result of your tooling moving the board after the camera looks at the fids. It also could be the camera itself hitting the board from warpped board or tooling raising the board up. It may be the camera

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

John, having worked at a major U.S. telecommunications co. I can tell you we were placing through hole connectors in SMT. Using MPM printers 3000 2000 AP36 AP24. We opened the apertures on the stencil 25% over lead diameter to allow more paste(it wou
