CoreXY Belts Calibration Slat

A simple 20x20mm square slat, at 45 degrees, with a simple notch to know orientation.

You can quickly print them to check and fine-tune your belts at your CoreXY system.

In order to do that:

1- Set your X and Y steps/mm to theoretical values.

2- Print this thing and measure both sides. There is no problem if they are not 20mm but they must be equal.

3- If they are not equal then:

If A>B then tight the A or lose the B belt

If B>A then tight the B or lose the A belt

When they are equal then you are set to calibrate your steps/mm for accurate printing. I strongly recommend this thing:

You can also print 4 of these slats, one each corner, to check if your printer has parallelism issues.
