Quieting down the nextruder buzz

I had a few parts buzzing and rattling on my nextruder assembly.  I manged to find the two main contributors and quiet them down significantly.  Check it out if you have a noisy XL.

Nice work!  I tried to leave a comment on your first video, but for some reason my comments never post.  Got to love YouTube.

I opened a conversation with Prusa last month regarding a resonance coming from the dwarf cover area.  They told me they are working on a fix and Input Shaping will also help with the sound.

Regardless, I tore everything apart on the extruder and came to the same conclusions as you did.  I put small round rubber pads on the bracket behind the part cooling fan, and I put the same pads on the dwarf cover.  It's darn near silent now.

Nice, yours does sound very good now.  I would love to see what prusa comes up with to quiet things down, but I am satisfied with my noise level and have moved on to trying to print as fast as possible before print quality breaks down.

Will def be trying this later today.  I hadn't noticed it until I started printing a large piece with rectilinear infill and man, it's buzzing like crazy.  Also, it's noticeably louder the closer the extruder is to the center of the X axis / gantry, which I suppose makes sense, since there's more opportunity for vibration/resonance the further the extruder is from the axis mount points.

Added a strip of earplug material between the fan/blower and the metal frame of the extruder.  Also added some little circles of earplug at each of those metal twist mounts for the board.  Certainly helped.  I also found that tightening the hinge screw for the flip-up cover helped a bit as well.  Not perfect but good enough for the moment.  We'll see if it's common enough of a prob to for them to release a modified shroud design.

Glad it worked out for you.  A lot of it could be fixed with some printed part design changes.  I think that adding flexible materials will still be a quieter solution.  It has been a few weeks and the noise is still gone.
