Stealth mode is loud

I’ve been running my preassembled Prusa i3 MK3S on stealth mode for a few nights now and at first it was running so quite. But now even on stealth with uniform shaped prints it runs louder than normal mode. Has anyone had this problem before and if so could you share what you did to fix the issue?

Hi. Have you found a solution? It seems to be a problem with the stepper motors in stealth mode. In normal mode the resonance is gone.

Hi cant think what that could be, i use stealth all the time now.

My printer is in the bedroom, its that quiet i dont have a problem sleeping.

I must say that i use damping feet, think that helps a lot, but one thing i found was last week i had a squeak on the X rod changed out the bearing for a new one. Regreased it all up and could not believe how much smoother and quiet it ran.

May be worth looking at the bearings, I  did find the X motor was loose

I looked for the bearings, the rods, greased everything. Maybe its a faulty Y-axis motor. I read in several groups, that some people had problems with the Y-axis motor in stealth mode. My printer is making so much noise, I cant use it in the bedroom, no way.

Mine on stealth is louder too. I think it’s down to the resonance and the surface I have it on. I also think my X bearings are starting to make more noise so I plan on regressing then soon (already done the Y bearings).

I am having the same issues, mk3s.. Its only 1 month old. I turn on stealth at night because I am light sleeper. I was working perfect and now all of  sounded it sounds louder then normal mode. I hope someone has an idea, if anything i am going to open a case.
