Scratched sides

Why does that happen?

The shorter sides are perfectly fine while the longer ones (Y axis) are uneven and ugly. The belts seem to be OK, as far as I can see and feel.

I would check if the x/y are perfectly (not off by a mm) squared.

Sorry for being complete noob in that, how do I check it?

And if you need to realign the axes, check this video for UMO+ (it's the same for um2)

Did as the doctors said, the prints look better for now. Hope, it will last.

Thanks everyone for the help.
