Did you calibrate before starting to guide Peter? MaximDL needs to know which direction to tell the mount to move when the star's centroid drifts from center. Calibration configures this. Good calibration is when you have a red L shape on the calibrated star. You'll see this in the guider exposures.

Peter.
If you're guiding at the same focal length, I would suggest 4 pixels to start with. Too high, and you'll loose the guide star or it will take a while for Maxim to recenter and settle.
