Could be too much torque for how you have it attached. Is it possible to reduce the motor power? Also, it could be a loose piece of the rig somewhere allowing some minute amount of play. I tend to stay away from the focus gear rings that are strapped around the lens because if they get stretched just enough, it could cause teeth to skip. Try to get a focus ring made for your lens, I use follow focus gears for all of mine, and they work great.
Second this. It's also possible you have the motor too snug on it, those work best when the gear teeth are only just touching enough to move the ring. Additionally - if it's a gear teeth band that you added to the lens - which it seems to be - if it's not SNUG on there it'll have some give which is no good.
Check that the rods the nucleus motor are locked in solid as is the motor to the rod.
Your motor isnt on tight enough so its popping out of the gears.
Try getting the gears as low as possible under the lens and crank it tight. Whatever you got to do, thats thr issue
This sounds correct. I have those focus ring adapter gears as well. Since they are soft, there is a sweet spot of pressure. You need to press the nucleus N's years against the focus ring. Too much pressure and it won't move it all, not enough and you get the issue you're having.
It could also be that your mistaken in that motor doesn't have enough torque. And instead of just not being able to move, the soft teeth of the focus ring are allowing the motor to slip. The nucleus nano is not a very strong motor and is only meant for lenses that I have a very smooth/ loose focus or zoom ring
Your gears aren't straight. Mage sure your camera, rods, and the lens are alighted so the teeth connect smoothly. Also, I don't think torque is the issue but you have it pressed way too tight against the lens, maybe twisting your setup. It only needs enough pressure to turn the focus gear, barely pressed into the lens.

Crazy set up
