Isn't backspin when you spin the trackball quickly in one direction and it actually moves in the opposite? Similar to how a spinning wheel can look like its moving backwards.

Truecade:

You're not alone.  I have this same problem on one of my cabinets using the Ultimarc trackball.  If I spin the trackball fast in one direction, the ball does not contact the roller well and movement is slow.  

If you figure out how to fix this, let me know.  :)

TheOtherBob:

Well I took the trackball apart and from a tip from Andy, I swapped the x and y bearings.  Plus I put a small drop of 3-in-1 oil in each of the 5 ball bearings.  While the ball definitely is rolling smoother, it still is a little slow when tracking up now.  I'll give Andy a shout and see if I can get another shaft... maybe that shaft just isn't making good contact.
