8.7.4 - Motor Calibration
The system can be "homed" from the debug menu. Type "home" from any capitalized
debug prompt and press enter. This should display the "HOME>" prompt.
The system (or individual axis) will need to be "homed" if an "invalid position" indicator
shows up in either the angle or position commands.
DC>home
HOME>
The system can go through a full calibration by typing "h" and pressing enter. The
elevation will raise (or lower) to a predetermined elevation. The azimuth will rotate
clockwise until it encounters the magnetic position sensor or hits the hard stop. If it hits
the hard stop it will rotate counterclockwise until it senses the magnetic sensor. The
azimuth will then return to zero degrees. The elevation motor will then lower the dish
until it hits the hard stop.
Each axis can be calibrated (homed) individually. In order to calibrate the azimuth
motor the system must be at or above a minimum elevation angle (10 degrees). In
order to home the elevation motor the azimuth must be at zero degrees.
Each motor is identified by a number. The azimuth is motor 0 and the elevation is
motor 2. The format for a specific motor calibration command is "h [motor#].
The following command homes the azimuth. Wait for the system to complete moving
before attempting to issue another command.
HOME>h 0
HOME>
Important Note: Typing "s" and pressing enter at any time stops all motors. The
calibration may not be complete.
