My Ender 3 v2 has some dimensional innacuracies I would like to fix, but I am unable to find the steps per millimeter controls in Cura. I printed a standart calibration cube, but the z and y axis wre scaled down by approximately a tenth of a millimeter,from 20 mm to 19.9. I am unable to find the current steps per millimeter.How can I fix these innacuracies in Cura?
