Mystery buzzing sound from MK3S after 3.9.3 firmware update
My 3 month old MK3S has always made pleasant, soft, robotic sounds when printing next to my desk. After upgrading to the 3.9.3 firmware yesterday, it makes an unpleasant buzzing sound when both axes are traversing (diagonal movements, as opposed to just x or just y movements). Downgrading to 3.9.2 eliminated the buzzing again.
Anyone else experience this? Any ideas what firmware modifications could have occasioned this noise? I guess if some drive frequency has changed a bit it might be hitting a resonant frequency in a part of the print head...

I noticed it too. On my printer I'm also no getting about 2 Y axis crashes per hour of print. Also, didn't happen on previous firmware.
