Power supply is getting scratched

[sabbot 0]

I use ender 3 pro. All of a sudden I noticed that the power supply of printer is getting scratches by the bed. I tried leveling the bed and unscrewing the power supply and screwing it back. But nothing help. Can you please help me to fix it?

There should be 6-7mm between the aluminum uprights and the bed.

1.  You could try completely loosening the leveling screws, push the bed to the left, and then tighten it back up and re-level.

2.  Drill additional holes in the uprights and move the power supply outboard where Creality should have put it.

3.  Put a finger full of grease on the area where it's scraping and say "Good Enough!".
