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 found the problem... the vx cable trunking was the wrong radius, so when the axis was moving at slower speeds to read pre stop position, the axis was not reading the platen correctly due to extra downward force.. Ive now replaced the trunking and

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

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

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

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
