Weird Z axis noise after firmware update

I have updated my printer’s firmware to 1.05.02.00 and now it makes some very loud noises when moving the bed up and down. Before this update, the printer used to be a little quieter…

Anyone experiencing the same issue?

Same her, and homed in the wrong direction.

mine is like making super crazy scratching sound when bed moving down to the bottom. Bambu said it is a protection mechanism…

Just adding to the thread that my 1.05.02.00 doesn’t seem to have affected anything. So it’s some of us, not all of us?
