Fix warm motor issue ...
I found my microtouch motor got warm after several minutes. I turned off the duty cycle from the robofocus controller but no help. After debugging, I found I accidentally put the useless (I guess 12v) yellow wire into the motor. After removing it, the motor still works and no more warm.

2020/05/24 Finally - new motor focuser for CFF 250 RC
With the new purchased focus motor, finally address the problem of focus position slipping.
I re-use robofocus controller on the new motor and here is how to wire it correctly.
Works great. Happy.
