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') ORIGIN Gregory Ercolano, Los Feliz California 08/23/90
