Extruder Hits MMU When Tilted Forward

When the MMU3 is tilted forward, the extruder Chimney hits the MMU nameplate screw when it gets near the top and causes prints to fail. It gives an error that X crashed, but it can't be recovered because the stepper motor slips. 

The bracket that supports the MMU on top of the frame has two positions - tilted back and tilted forward. This happens when it's tilted forward. You'd think I would have learned after the first time, but this has happened twice and caused my 10 hour prints to fail which is very frustrating.

Please fix the bracket. See pictures.

RE: Extruder Hits MMU When Tilted Forward

The MMU shouldn't be tilted forward like that, you should be able to push it back so it is leaning backwards to secure it. Please review the official docs: https://help.prusa3d.com/guide/10b-mk3s-mk3-5-setup-and-calibration_334155#394406
