Adjust the gantry tilt-stop angles (encoder calibration)

Verify and, if needed, adjust the tilt detection unit (the encoder that reports gantry tilt angle) so that all six tilt stop/limit positions fall within the standards below. Run this check whenever tilt behavior seems off, or as the recommended re-check after mechanical work on the tilt drive (for example, after replacing the gas spring — see Related).

Safety

CAUTION

Hazard: Placing a foot on the stand base cover while tilting the gantry to check each stop position

Consequence: Foot caught — injury

Avoidance: Never place your foot on the stand base cover while the gantry tilts
