U-Trak jitter
Ummon:
I had some slight worries about something like this when it came out because of its height relative to where the rollers would have to contact.

This height is exactly the same as the Happ trackball. The contact points on the ball are the same. This was one of my design requirements. This effect is no greater on the U-Trak than any other trackball, when spun to the limit.
The problem sounds like a faulty optical encoder PCB. This could be confirmed by swapping the 2 PCBs over. A replacement is on the way anyway.

Ahh, thank you. A mistake I made by eye-balling it.
