On my CR6-SE, i have made all necessary calibrations via printing 20mm xyz cubes.
After the calibration, when i print the same 20mm xyz cube, the print comes with accurate dimentions which is 20x20x20.
But when i try to print something bigger like 150 x 30 x 20 mm the print's dimentions comes so much different than what i have designed.
What should be the problem? Any idea to fix it?
