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

I have an ap-25 and wish i had gotten the UP-2000 instead. How's that for an answer? The main difference is that the ap-25 uses linear motors and air bearings, whereas the up-2000 uses ball screws. The linear motors are faster, but the whole thing i

Currently working through a myriad of air leaks on an old MPM Ap -b and have a question that hopefully one of you fine people may know the answer to. The camera vx and vy use linear rail motors. As far as I can tell, there are nozzles between the sur

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

Sounds like your board stop sensor is not working properly so it's not seeing the y-stop/board edge when the board enters the center or the machine. You could try taking the camera cube cover off, jog the camera over a board then move the board back

Mr Duckmann2000. Where is the leak??? Is it up on the dispenser behind the printhead? If so the simpliest thing to do, assuming you are not using the dispenser, is to cut the incoiming air tubing to the dispense pinch, fold it over and ty-wrap it.

I am assuming this machine has a tactile sensor that mounts to the printing table. If the air connection or any of the wire connectors get under the rear rail it will cause the Z to fall. Also any bare wires on the tactile sensor that touch the prin

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
