After printing the Calibration cubes, I do not know where these G-Code came from though they printed in excellent condition.

If you sliced them with Pruseslicer post your 3MF file will look at your settings.

Cubes were sliced with cura nd prusa slicers, i didnt get 3mf that time, but i recreated that project:
