In NINA software there is a function called Overshoot Backlash Compensation. We need this for EAF in asi air
N.I.N.A. compensate for Backlash by overshooting the target position by a large amount and then moving the focuser back to the initially requested position. This method is much more forgiving than Absolute and is recommended for focusers with large backlash or when the backlash measurement is not very accurate. For Overshoot, once the user has determined a rough backlash value, this can be increased by an extra 50% and input as IN or OUT compensation. Since this method is very forgiving a trial-and-error procedure is also possible, by using progressively larger compensation values until the AF routine behaves properly and no sign of backlash is shown in the AF curve.
