Hello, I don’t think the sounds are normal how can I fix that? Probably something with the z belt. It’s only when I move the bed down.
this sound is not normal. I do not have such a noise moving the bed down.
with best Regards

Are the lead screws clean?
Have they been cleaned and greased again? This might help some until support can get back with you with a solution. It would be nice to grease the bearings but they are shielded for contamination.

Is it possible the cable bundle behind the rear Z lead screw is rubbing against something? I’ve heard a similar sound as the bed nears bottom and those cables bend more and touch the enclosure. In your case perhaps the rough plastic sleeve is against the lead screw.
The Z rod is gripping the heatbed cable protection slieve. Try to reroute it.
They are clean and greased, it sounds like there is filament stuck or something… but I can’t find anything
I’ve also put a little grease on the bottom z belt but nothing got better
