Banging Noise

I reactivated my prusa mini after some downtime. Before doing so I did some maintenance work (lubrication) and noticed a banging noise when the print bed moves it‘s axis in this position (Video). I haven't changed anything to the original state the printer came in, yet I'm convinced this noise wasn't there in earlier days.

Prusa Mini banging noise

So far I've flashed the newest firmware and had a look at the belt - I believe tension is fine and bass note-ish. I understand that the axis calibrates itself and therefore "hits" the endstop - yet the "intensity" of the sound worries me.

I’m a little concerned that he current state is going to introduce issues through the unintended mechanical wear. Has anyone else experienced this “intense” noise right after the mesh bed leveling? Anybody have some experience with that? Solutions to fix this?

So I just downgraded the firmware - issue is slightly better. Upgraded again to V4.3.1 and the problem is gone! Seems it was software related in the end..?

It may be the angle of the video but it looks like the heat bed wiring is hitting a black box behind the printer?
