Motor Config -> Backlash Compensation
Backlash, sometimes called lash or play, is clearance or lost motion in a mechanism caused by gaps between the
parts. Motor's gearbox or other components in the focuser can have an amount of backlash.
Compensation will be invoked when the move in opposite of the compensation direction. Just make sure the
amount specified is more than needed to remove the backlash.
To enable backlash compensation, set Backlash Comp to ON and type the backlash step number at the popup
window. Click OK.
Setting is stored in the EEPROM and backlash compensation is applied on every motor movement.
