Is this grinding noise on startup normal?
Had some issues which seem to be fixed (filament threading, grub screw was stripped), is this noise normal when its starting up?

RE:
If anyone runs into this issue, try opening up the mmu3, untightening the grub screws, realign them so one of the grub screws is on the flat part of the shaft(for me the flat part was on top) and then tightening everything back up.
Lucas from Prusa support helped me figure this out, thanks to Frank's video here!
