Also check your belts/tensions/pulleys and motors on the camera axis. If you are getting any slippage then the camera will not be in the position the encoder says it is. It may still read the fids but will produce an offset.

It happens on the middle of the stecil cleaning. The camera and the cleaner will stay under stencil in half way back. Then machine asking the initate the motors. If to press initate then the pcb stopper will hit the rails. Usually we move camera and

The camera is probably clipping the top of your board when it is reading fids. This causes the motor to lose steps. Manually load a board to vision height and drive the camera over the board to check for clearance issues.

I have a Philips CSM84VZ. There are offset calibrations that compensate the X and Y distances from the camera to the heads and the beam pointer. Perhaps yours is similar and just needs a small Y adjustment for the beam pointer.

One other thing to check is your PEC camera. Universal uses a jig to calibrate this camera but you could check it using this method. 1.Run about ten 0402 parts on tape with the PEC camera off and check placement. If the placement is off change the x\

We recently scrapped our TP9-2U because of an issue similar to this. The X-axis would overshoot the pick and place positions. This particular machine(2U)only has 1 X motor. The UFP's and the MY machines have a small fine positioning motor that is on

I am assuming that the card that was changed was the motor driver card. Did they change the card with a known good board or just swap the X and Y cards. If they swapped cards it appears that the card that is now in the X motor slot is bad. Open the a

You should be able to see the counts in the service screen for the motors while testing them...that's usually the easiest way to see if they're functioning...at least the encoders. In some of the older systems, the drive motors were all the same, an

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
