Axis linearity calibration test

thingiverse

To verify the accuracy of my prints, I created a test piece set with sequential markers. Ideally, all six pieces should be identical, except for the sequence indicators. Additionally, diagonal pieces (numbers 5 and 6) must be straight, while others should also be aligned correctly. Regrettably, my test pieces are far from identical, suggesting a non-linear relationship between stepper rotation and X-axis movement. The steel reinforcements in the X belt were completely damaged.
