Loud grinding noise
Is anyone else experiencing a loud grinding noise when their MMU3 starts up? I'm running the latest firmware for the MMU3 and the MK4. But I had the same noise with the last versions of firmware.

I have that noise too. It's difficult to say whether it should be "normal" or if something is wrong. However, printing with the MMU3 seems to be ok for now.

I have the same question and cannot find an answer in this database.

Apparently, judging by other comments here, it is harmless and does not impact the function of the MMU3, but I would still like to have a solution for this, since it is quite annoying.

Same noise here. It's happening when the idler turns. My guess would be that at least one of the bearings rattles on its shaft.
