Hi Ron,

I've run in to the same problem a few times myself,
in my case I was able to trace most of it to the project board or sled slipping on the Traction Belts or Board Sensor, the bottom of the board was to smooth or to slick. I was able to solve those problems by scuffing the bottoom of the board or sled with course sand paper or by adding a couple or strips of painters masking tape to the outter edges of the project where it makes contact with the Board Sensor. The last time it happened, it turned out to be a loose screws on the "Z" truck, causing the chuck and bit to wobble. Also a few folks mentioned the project board binding from the guide plate being to tight or the project board's sides not being parallel from end to end. Hope this helps a little.
