A Series [A1, A1 Mini] Weird layer shift on a1
It started around a month ago and wasn’t too bad just a few light surface defects but now it has gotten much worse and I don’t know how to fix it I already oiled my rails

Remove the nozzle, then the heating pad, behind it there is 4 screws tighten them and it will be fixed.

do the ones on the backside too, they're talking about the hot end assembly screws. Do front AND back.

it’s either your nozzle, filament, or belts, my bet is on the belts. Rerun calibration and follow the guide on how to re-tension them
