Stealth mode is louder than normal mode  

RE: Stealth mode is louder than normal mode

I have the same problem! Did not find any cause too...

RE: Stealth mode is louder than normal mode

Check if your LCD enclosure (the orange thing) may be hitting your table. This can happen if your table is not quite flat or your LCD enclosure is mounted a bit low. You can quiet if down by sticking a folder piece of paper under it. I had this issue until I raised my printer higher by making new legs.

Hi, LCD is not touching the table. Nothing apart from 4 legs is touching it. Plus as @johann said above me, it only happens during stealth mode. Here's a video to illustrate that noise. I really need your help guys, cause it's driving me crazy 🙂 Thx

It it something in the PSU? In my case was something loose in the PSU. I solved it changing slightly the aacceleration in the slicer.

I don't know to be honest. Whole machine resonates like crazy during stealth mode. I tighten every bolt I could find and it helped a little bit. I will try to change acceleration like you suggested. Could you tell me what you changed? Thx

I have the same problem. Do you have a solution?

RE: Stealth mode is louder than normal mode

Sorry, no sulution, I use normal mode and it's not so a big matter, because it's silent enough.

RE: Stealth mode is louder than normal mode

Ok. Thank you for the answer. Maybe someone else can help.

Hi.,

It turns out main reason for the noise in my case was the LCD screen.  I unscrewed it from the main frame and it helped a lot. I also bought a granit paver 40 x 40 x 2 cm to use as a priner's stand and went back to original rubber legs. It really reduced vibrations and noise of the printer , both in normal and stealth mode!

I had the exact same problem with my i3MK3S. Printer was placed on a small & light Ikea table. Generally loud & no noticeable change in Stealth Mode. The table surface was amplifying the noise, like a drum.

Solved by placing a concrete paver under the printer, and a towel between the paver & the table (see photo).
Has made a huge difference in noise, and stealth mode is truly silent (the cooling fan is the loudest part).

RE: Stealth mode is louder than normal mode

I have never used stealth mode.  My printers are quiet without it or maybe I am half deaf.  I do have them on 18-inch tiles with cork insulators to reduce noise.

I've noticed the same thing, when I formly hold the display the noise is gone, I will detach it and add some rubber dampening.

Just to show what I had going: https://imgur.com/a/Zn3QgYd

I squished some rubber stickers between frame and display, now the noise is gone, for now.
