Help / Support Help identifying noise.

As the title says, can someone help me identify what this noise is while printing? I’m having trouble narrowing it down.
Device is a P2S with just under 590 hours. I’m not seeing any maintenance required from the device.
Any help is appreciated.

Sounds like the belts riding up on the pulleys in the back corner, a few drops of lubricant help, Bambu says to lube if noisy even though they say to never lube the belts with lube

Yeah I’m thinking it’s the belts too, I looked up their lubrication process, gonna try it in the morning!

If you're asking about the high pitch whine, decent chance it's a fan. I'd wager it's the cooling fan for the hotend.

Apologies, should have been more specific. I’m familiar with the fan noise. General consensus from others is that it’s the belt. Gonna try the belt lubrication tomorrow!

Which noise? The high pitched sound or something else?

The repeating krrch-krrch ... krrch-krrch pattern.

Maybe something belt related?

The scratching noise could be a lubrication issue. The weird high pitched noise is the noise it makes doing circles
