Focus Commands

• fsync [-w]                        - move focus to sync position

  The fsync command moves the focus motor to the home position, and resets the focus encoder to 0. This command must be run before an absolute focus position can be used.

• fmove [-w] -a position            - move focus to absolute position
• fmove [-w] -r offset              - move focus offset mm

  The fmove command moves the focus to an absolute position or a specified offset. The focus is measured in millimeters. Under normal use, the absolute positions are easier to keep track of, although the current focus postion can always be read from an rstat command.
