High pitched noise from the extruder (not from fans)
Hi, I have brand new Prusa i3 MK3s (which I built from the kit). And while printing (in the stealth mode) there is a (really annoying) high pitched noise coming from the extruder, somewhere between 16kHz and 20 kHz (see attached image). It is NOT coming from the fans, when I stop them the noise is still there unchanged.
Is there something I can do about it?

I find that stealth mode sometimes generates resonances that are much louder than normal mode. It depends on what you print. I typically print in normal mode and it’s quiet enough.

You're probably hearing the PWM/stepper drive noise. I hear it too and it stops when the stepper idle timeout occurs and the motors shut off. Not much you can do about that, though it is reduced in stealth mode due to reduced motor currents.

Don't worry its something that goes away when you get older lol.

Hi,
I know it's an old topic, but maybe someone is also searching for how to resolve high-pitched noise.
In my case, it was indeed current flow via extruder motor. I turned on E-cool mode from the experimental menu and the noise disappeared almost completely (hearable only during retraction, so probably also could be tuned) ( https://help.prusa3d.com/article/experimental-menu-mk3-s-_161213).
