Y-Axis Stepper Motor Clicking

Hello,

I've done ~100 hrs. of Prusa Mini printing (in terms of print time), and my Y-axis stepper motor has begun making an annoying, noticeable clicking noise. The noise appears to be coming from the inside of the stepper motor, and it occurs once per rotation in the same location. (I.e. if the click occurs, say, at 0 degrees rotates, and you rotate the shaft a full 360, there is always a click at that 0 degree point.) I purchased this printer partly for the silence (which is normally very good), but this clicking is very irritating and makes overnight prints not fun anymore. I have a little apartment and used to print in a different room, but the clicking is quite audible and makes it more difficult to sleep.

Despite the clicking, there is no noticeable loss of print quality, and my prints look great when completed (despite the frequent clicking). I'm wondering if this is something wrong with my belts, or whether there is plastic jammed somewhere, or whether it's a possible warranty replacement.

EDIT: This has occurred on multiple FW versions. I have used all FW versions so far, and am currently on 4.0.3-RC1 (even though this also happened on 4.0.2).

Update: For anyone having this issue, I contacted Prusa Support and they are shipping a replacement motor. They may also have me send back the failed motor for investigation. This issue does, apparently, occur sometimes on the MK3S but it is quite rare. And, yeah, that's about it and I'm glad Prusa stands behind their products. 🙂

New videos of the problem

Note that the videos don't do justice to how loud the clicking is. The clicking sound travels about twice as far as the actual printer motor noises.
