calibration cube weird defects

i just tried to print a calibration cube, but i get strange defects in x direction. I have already tried slicing the stl with another slicer and placing the cube in a different position on the print bed. None of this has helped and I still get the same result. Do any of you have an idea what this could be?

Check your motion system... Belts tight enough? Pulleys tight on motor shafts? No debris in belt path?

Thanks! I tightened the belts and now the print quality is great
