Actually I had that too, I ended up loosening everything off so the focus knob inner could spin in the plastic insert, loosened the bolts that hold the focus motor on to the scope and just wriggled everything about to allow it to find it's own center. It is still not a great setup and you can hear it has a tighter spot once per focuser revolution, but it has been working for the last year or so.


I have been thinking of changing mine to the ZWO EAF now that they have a bracket for the C925, not likely to be stranded investment if I change scopes given it is a generic focus motor.
