My new printer has a problem with bed leveling. When I unboxed it, the print bed was lower in the center by default. I was able to mostly correct it by raising the four center mounting screws (I added four 1 mm spacers).
However, the rear side along the Y-axis is still not level, and I don’t know how to adjust it. If I lower the two rear corner screws to level the corners, the rear center sinks down again.
Is the bed itself warped? Is there another way to adjust it?
I noticed there are four wheels with screws underneath the bed. Can these be used for adjustment? They are closer to the center of the bed, so I assume they won’t help much with the rear Y-axis issue.
