thingiverse

This is just a flat square, to test the bed level. In Cura, put it int the middel and save it as a standard quality 0.2mm There's a 1 layer of 0.2mm and a 5 layer of 0.2mm Print it out in the middle of the bed. The print should be consistent and flat. When this it pretty ok, you can start with your auto bedleveling procedure.
