I had some success with a moonlite DC focuser and Focusmax.
I suggest you move your mirror forward so you're operating in the middle of the focuser's range if that's possible.
I would start by racking the focuser all the way in, then moving out to eg. 5000, then zero the position in Focusmax - this lets it start from a known point. A servo focuser will never be as repeatable as a stepper as there is no feedback as to whether the motor has actually moved in response to the pulse. I had more repeat ability of my results by following this method.
The tutorial about the LX200 microfocuser was what I used as a guide.
