Weird sounds when moving bed down please help

Leadings screws cleaned with ipa still sounds like filament is stuck or something, but I can’t see anything :frowning:

I have already completely removed the z belt and cleaned everything with ipa, the sound is still there :confused:

Hey there,
I saw your other post regarding this topic, sadly both of your videos arent up anymore. Do you still have a problem with weird sounds on z movement? I noticed sounds earlier this day.
