My A1 has been scarring the plate on the prime line since day one. I found 2 out of 3 bed screws were very loose, but when I tightened them, the bed started dragging/binding. I had to loosen them again just to get it to move, but now it’s back to digging trenches in the PEI.

Nozzle is clean, but even after flipping the plate, it’s still happening. If I can't tighten the screws without the bed jamming, what am I supposed to do? Has anyone else dealt with a bed that binds when the screws are actually tight?

You can see right at the end of the prime line it digs in. Thanks for the feedback!
