Question about Logitech Trackman Marble Trackball
My Logictech (Trackman Marble) thumb ball is okay with large, sweeping movements but sticks when I get down to fine movements. I've cleaned it and polished and brushed off the teflon points. Any suggestions (polite) would be greatly appreciated.
I have a total of six Logitech trackballs; four of the newer Trackman Wheel model, and two of the older Trackman Marble+ model (as pictured). All but one of them suffer from the problem described by dave48. The fifth, for some mysterious reason, never has this problem.
The solution I came up with is to light a candle and let melted wax drip onto the red thumb ball. A single drip falling on three random places on the ball usually does the trick. (The wax should dry as soon as it contacts the ball.) I then start moving the ball around to work the wax onto the teflon points. The movement will be VERY rough initially, but will gradually smooth out the more you use it. Sometimes the initial three drips aren't enough and the ball starts getting rough again, so I will melt three more drips of wax onto the ball and work them in as well.
This really seems to do the trick and for some reason the points don't seem to need cleaning as often either. You do have to be careful not to remove the wax when performing a cleaning, however. But if you do happen to remove some wax all you need to do is melt some additional wax onto the ball and work it in like before.

The ball in trackballs is held in position inside the ball cage by three ball bearings. If one of these bearings becomes dislodged or is missing, the ball will not rest evenly and the tracking will be affected. To see if this is the problem, remove the ball from the ball cage. (This may require removing the retainer ring or simply pushing it out.) Inspect the ball cage and look for three tiny bearings. If one or more is missing, please contact Logitech Sales at 1-800-231-7717, US and Canada, for replacement bearings. Please note, a shipping and handling fee may apply.
