I have been having problems with the x-axis skipping randomly, on multiple jobs, with laser engraving (though so far not on cutting). It is not in the same spot each time and does not "jump" the same distance--one time it may shift a quarter inch and the next it's an inch and half. However, I do hear a "click" right before the shift.

We have a ULS 6.60 laser that is four years old. The x-axis pm was performed in February this year (new belt, bearings, idler, and drive gear motor).

We have taken the x-axis apart and cleaned and inspected the belt and all other parts, and double-checked belt tension with a spring scale.

I have called Universal Support several times, but haven't got any other suggestions. I have jobs backed up for the holiday rush and am starting to panic!

Any suggestions would be helpful. Thank you in advance!
