Focuser Preferences



Polling Rate

The the time in seconds in which the focuser is polled for temperature and position. Some focuser struggle with a 1 sec polling rate, setting the rate may helps, default = 1


Limit End of Travel Position

This setting allows you to guard band or limit the full travel so as to avoid hitting a hard stop. For example, if the setting is 10 steps, the the focuser will only travel between position 10 and max travel - 10, default = 0



Backlash Compensation

This is used to set the desired backlash compensation value and direction. Use this feature if the focuser driver does not allow backlash compensation or you wish to have FocusMax make the required focuser moves. Backlash compensation is important as FocusMax is designed to drive the focuser in one direction toward the focus position thus eliminating error in the final focus position.

Do not activate FocusMax and focuser driver backlash compensation at the same time.
