Vibrating heatbed after 25d printing time and 635mtr filament

A few months ago I build this printer and have been printing a lot. Now the heatbed starts making some noise when printing. I checked all the nuts and cannot find anything loose. I also tried servicing and greasing (as in the manual) and recalibrating. When I put my finger on the right side of the bed while printing the noise stops. When I tap my finger on the board (when not printing) I hear a sort of tremble/vibration. What can I do?

Check the smooth rods are securely fitted.

Step 27 on:  https://help.prusa3d.com/en/guide/2-y-axis-assembly_165795

Check the Y carraige mounting, step 21 on same page.

Cheerio,

somehow the middle is the most stable

Thanx I checked that but could not find anything loose. Somehow the middle of the plate is the most stable and all 4 corners resonate a bit (video)

Normal.  Bearing noise.  Don't like the noise?  switch to Drylins.

Carefully loosen and retighten the bearing clips; if yours is the older style with the U bolts take extra care not to overtighten them.  Instructions on the same page as above.

Cheerio,

I don't mind the noise but am carefull and single newbee. No people around that I can ask whats normal. Thanks @diem that worked for me. I also swithed to ghost mode for the first time and are going to keep it that way for now. Thanx all!
