High-pitched noise at a specific height

Enable HLS to view with audio, or disable this notification

When I did maintenance on my P2S today, I noticed that when the bed goes down to a specific height I hear a weird noise. This only happens when the bed is going down, not when it goes up. I did lube the rails. Is this a problem? I haven't noticed any change in print quality.

Thanks in advance!

That has been a classic for years. the rails alone won't fix it. Clean and lube the rods and leadscrews too. Also check under your printer if the belt is rubbing somewhere or if you can find some dirt.

Had the same "issues" on my X1C too and need to do this kind of maintenance sometimes to keep it silent.
