We have one of the ones that Jim made to control the bartech from the gimbal, but it has been acting up pretty badly at the top and bottom ends (lots of shimmy and shake, and sometimes it resets itself half an inch back or so)

 

Is there any solid alternative that plugs into the 4 prong focus control?  We've seen the G-zoom equipment but I think it might be overkill for what we want.

I have one as well and so does Kyle. We both noticed that if you are not turning the wheel for a while, it falls into some "sleep" and you need to move it again to wake it up, resulting in a jerk of the motor. that happens more with very slow and small moves.

Have not found an alternative to it so far.

Looks like we just needed a new potentiomenter and to pull back a couple of inches on the wiring.  Wiring was shorting out from crimps, and potentiometer was fried.  New one is about as close to perfect as we could ask for.
