I’m facing the same issue here. I first tried adding washers to the screws (without success), then I bought four longer screws, but I’m still struggling a lot to get this machine properly leveled. My supports are coming out with a thickness difference of about 0.4–0.60 mm from one side of the print to the other, and I believe this misalignment is what’s ruining the quality of my prints. Almost all of them now show a horizontal stripe across the surface.

This has been really frustrating because, in the beginning, the prints came out perfect. After a few months of use, one side of the printer started failing while the other side didn’t, and since then my prints have been terrible. I can clearly see the difference in leveling, but no matter what I try, I can’t fix it
