MOTORS(OPCS)		Optical Printer Control System		MOTORS(OPCS)

    NAME
        motors - enable/disable the motor hardware for debugging scripts

    USAGE
        motors [on/off]

    DESCRIPTION
        With off as an argument, this command will disable motor
	movement, causing any commands that run motors (pro,cam,rep,go..)
	to NOT move the motors. Counters will run, but the motors will not.
	Also buckle/viewer checks will be disabled, not checking the
	actual hardware.

	This command is useful for testing OPCS without motors and without
	any actual hardware connected. Such as developing camera 'run' scripts
	on a portable computer, to be run later on an actual printer.

	Run scripts will execute faster when 'motors off' is in effect,
	allowing one to speed up debugging of 'run' scripts.

	When motors are disabled with this command, the current position
	of the motors are saved. When you re-enable the motors with 
	'motors on', the counters will revert to the previous positions
	just before 'motors off' was issued, avoiding confusion over
	where the motors REALLY are.

    EXAMPLES
        cam 12        # Runs the camera 12x
	motors off    # Disable running the motors
	cam 12        # Counter will advance 12x, but motor wont run
        motors on     # Enable motors. Counters revert to actual posn. 
        cam 12        # Run the camera normally

    SEE ALSO
        CHK(OPCS)  - check if counters are where they're supposed to be
	RUN(OPCS)  - run OPCS command scripts (quickly with 'motors off')
