Slow Trackball Tracking
<< < (2/3) > >>
TheOtherBob:
Just an update.  I took off the caps on the sides of the trackball and took a look at the encoder wheels.  When I spin the ball to the left quickly.... you can physically see the encoder wheel moving slowly... or eratically.  That would explain the slow pointer movement on screen.  Sometimes it moves just fine.  I got a tip from Andy (ultimarc) to try and soak the bearings in wd40 a bit.  We'll see how that goes.

Thanks....

NO DON'T DO IT!!!!!!!!!!!!!!!!

Check out Bob Roberts on fixing this.  DON'T USE WD-40... I should have listened, but I didn't, I had to get new bearings...

Not familiar with the Ultimarc trackball, but is there a spring loaded wheel at a 45 degree angle opposite the rollers?  There might be an issue with the spring pressure, or alignment of that wheel.

OK!  :)  Thanks for the heads up.  I didn't get around to it last night.  I'll hit up Bob's page for some more info.

There is a wheel there at 45 degrees, but I don't believe it has a spring to create pressure in it.  I'll have to check it again.  Thanks.....
