home rotates the filter wheel to the home position. This must be done whenever the electronics are taken off the telescope or the computer is turned off. Note: home is not filter 0 but is instead position 2.5 (in between filters).

step= moves the filter wheel the specified number of steps. Use this command to make small motions of the wheel off the center position. There are 400 steps per full rotation of the six position wheel.

tense - turns on the motor power and keeps it on. Caution- this will heat up the dewar.

relax- turns off the motor power and counteracts the tense option. The motor power is normally turned on just for the duration of rotations specified by the num= or home motions.

home_force - tells the controller that the present position is the home position.
