Issues with sensitivity on CH Products DT225 Trackball
« on: Sat, 10 January 2015, 22:31:37 »
I received a brand new CH Products DT225 trackball in the mail last week and I'm loving it. My only issue with the trackball is the low sensitivity, even with the dip switch flicked to double the speed. To make matters worse, the trackball is a lot more sensitive moving to the right than it is moving to the left. For example, if I want to move my cursor from my first monitor to my third one, it takes about 3 full rolls of the ball, which is pretty good. Moving the cursor the equivalent distance back takes 8 full rolls of the ball, which is much slower. Any ideas how to fix this imbalance?

Are you sure it's a standard model? The reason I ask is that all of these industrial-strength trackball companies do runs for special purposes. ITAC have a model specially designed for use with BAE Socket Set (very high end mapping software) and I have an Evergreen trackball made for the US Navy. All of mine, however, go the same speed in all axis.

Since the same sensor handles both right & left, I can only think of a bearing with more drag in one direction, in which case it might break in. Or, as I said, it might be a special model designed that way. (Who would be so crazy as to want that behavior?)

Yeah, I'm pretty sure it's a standard model. I'll just hope that it breaks in because I really love using this trackball.
