Adam: I would say that you do have a reliability problem. - check parts for solderability - check your board finish - check your profiles - check your paste - check your processes with focus on cleanliness - do some mechanical tests, you should rath

maybe you should check the mechanism .such as the drum with the twenty shaft.and A,B AXIS'S synchronization.and the clearance fo the helical gear.check the cutter and no strange sound, check the lens and no dirty or stable.check the twenty shaft.

By any chance is it eutectic paste and pallidium leads? Also how tight are you checking coplanarity? At least with the MPA-G3 you can check so tight that any IC will fail in the real world. Or you can check so loose that you might as well not check.

5mm. 3.Check that there are fiducials. The above checks are purely for Processing the board thru the machines. There are lots of other checks for stencil design etc. aj...

1. Check for pins or something else under the rails. 2. Check the motor for the axis and the sensor that defines up position(I doubt it there is an encoder for this motor) 3. check card 4. check interface cable

CHECK IO BOARDS STATUS, CHECK HEAD IO 24VDC SUPPLY, CHECK 24VDC SUPPLY TERMINAL, CHECK WIRING CONNECTED TO HEAD IO I think this is an I/O communication problem. Fail in connecting to I/O cards.
