Steps Calibrator
thingiverse
This is a simple way to fine-tune your movements. Use a caliper to measure X/Y when it's attached to the bed. Rotate the X/Y model 90° if you need longer measurements, which will make calibration easier. If done correctly, you'll only need to do this once and achieve a 99.5% accurate printer. Please let me know if any information should be added to make this test more straightforward and user-friendly. Also, if other models could benefit from these steps, please share your knowledge. I'd prefer it if others contributed to enhancing this single guide rather than creating a new one.
