mulcmuA digital bubble level was built to measure the platform tilt over the travel range. This consists of an ESP32 dev board with 1.9" LCD and Sparkfun ICM-20948 breakout board. The base was small enough to mount on the effector platform (with hot end removed). Some python code was used to have Klipper move the platform around and record the x and y tilt from the bubble level.
