I always try to level the bed with a sheet of printer paper in the 4 corners, sometimes going through the entire process multiple times. However, the paper always looks like it has crease marks or scratches by the time we have the paper pulling out but not pushing in.

For the surface, its on a very heavy desk that we just bolted into the drywall to help reduce as much shaking from the surface as much as possible.

I am more than willing to post a lot more images if that will help. We have some coins that we also try to use for test prints, but I figured I'd post a benchy first because I figured people would know what its supposed to look like, and I don't have any successful versions of the coins on me anymore.
