Hello, I have fixed the issues with the centering. Below the centering head there is a adjustment screw. First you have to remote a few screws to get access to it. They you can turn the adjustment screw to align the centering jaws.

Calibration was done improperly or you have a bent mount tool.

Hello, I have some troubles with my MyData TP11-UFP with the precision of the placement. All the parts which are mechanically centered are slightly misaligned. Attached are some pictures of 0603 and a SOT23 part. I have made the calibration but it

+1 to what Sr. Tech said. I'd also add that you could have some uneven deterioration of the centering jaws. Check by doing a couple of things (this will help check if the tool/tip is bent/deteriorated as well): 1. Turn off mechanical centering, and

Yes, I took the chuck off head 3, and made my own nozzle, which is working quite well. I can't set head 3 to vision, as this machine doesn't have the vision system. I set it to "IC" and that seems to work fine. I set mech alignment 1 and 2 to yes,

Hi Bobpan, Regarding "second", the results of the test are no difference - still rejects the part. I tried 2 mils, 3 mils, 5 mils, 7 & 9. I changed the tolerances fron about 15% to 20%+. By the way, I did put on the new nozzle and it is still the sa

I was hoping somebody knew how to do this. My method was to place parts at 0 and 180 degree rotation, and adjust head offset until the parts were in the same position at both rotations. Then, I adjusted the M.A. station offset to zero in on correct
