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.

New Toy - William Optics 51

Need to get a shorter adapter to get enough in-focus. SBIG sucks.
