A precise way to calibrate your X & Y steps per mm.

Instructions:

1. Download the model and 3d print.
2. Measure all sides and adjust your steps per mm (This is done by dividing 20mm by your measurement for that axis, then multiplying your stepper's settings by your result for the axis).
3. Inspect the sides and adjust the bridging speed and input shaping or jerk and acceleration settings.
4. You could also stop a print half-way to measure the cube's wall thickness so that you can fine-tune your extruder steps.
5. Repeat these steps until you perfect the 20mm calicube.
6. Then send a picture to show off your cube in Comments & Ratings tab.

And don't forget…

Happy calibrating!
