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

MPM uses a one-print-Mylar system, as do other printer mfrs. In this system there is a Mylar sheet attached to a frame that is secured over the printer table with the board on it. You print onto the Mylar. The table X-Y-theta manual adjustments are u

OK if the paper is transparent and you can adjust the table X-Y-Theta under the paper- without moving the paper - the align with the solder lands on the board. If you have a DEK or MPM machine, the Mylar frame is like $300. I belive other printer mfr

Vision X-Y maintenance procedure, please advise. I have problem with camera not park so often time, and I don't have any solution accept buying a new vision Y right stepper motor, but that's just too much money roughly 2500 dollars.

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

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

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

During the start the error "DOWNLOAD VISION ERROR" - instead of "OK" is "NG". - resolved - video card died. But I still have a motor overload error Y1 (L057:CUR.DEV ... Y1 error) - what resistanc

I am new with MPM printer,need help.I am trying to teach a new board, after selecting targets,when I exit teach vision ,it errors out "Board Model Not Found". Board orientation is correct. The books talks about Vision Y not squared to axis. Does anyo

I think you are right. Board stop on Y. Vision square is the stencil fiducials. So if you are using pads.... I am not sure. But why didnt you used board fiducials? none on the board?
