Hello people.
Yesterday i moved the bed down and heard a grinding sound almost like a squeaking sound. When i move the bed up there is no sound but when i move it down there is a sound.
I cleaned the 3 lead screws and tried again and the sound disappeared. After that i lubed the lead screws and let it print.
Today i moved the bed down again and the sound is still here. I did the same procedure and this time i cleaned and lubed the linear rails again.
The sound its still here and there is no difference when cleaning or lubing the rods or the lead screws.
I doubled checked if there is a filament or any dirt but everything seem clean.
Could it be a pulley underneath or a bad ball bearing? The weird thing is that is doing the sound only when moving down.
Thanks
I have the same sound, did you find a solution?
Update: I put a drop of super lube on all the Idler Pulleys underneath the printer (avoiding the belts), and that fixed the squeak I was getting when the bed would move up and down.
I did exactly what Bambu suggested for the Rear Idler Pulleys, but on the Bottom Idler Pulleys.

Do you mind elaborating on what you did or sharing a link to what they suggested for the rear idler pulleys? I have an X1C that just started making this noise after just under 300 hours of printing.
All you have to do is to lube the edge of the belts near the pulleys. Just apply a small amount of ptfe lube on a cotton swab and drag it on both sides of the belt. Not straight to the belt or the grips. If squeaking still there apply some ptfe oil under the pulleys. Be gentle and dont apply to much oil.
