I didn’t really run into problems when leveling my bed. However, the first time I tried to print the dodecahedron the print failed. Even the skirt around object was wonky, as seen below. I noticed that the y-direction bed movement was not smooth, so I loosened the wheels holding the bed onto the rail a little. I also re-sliced the .stl file and changed the infill type. I’m not sure whether it was one or both of these actions that fixed the problem, but I was able to print with no issues.
