My P1S is on my desk. It has two monitors, a laptop, and a filament dryer. During printing, the monitors shake from the vibration. And during video calls, you can see on the laptop camera that the display is trembling. I used to have my laptop in a room where I could attach the desk to the wall. Now I don't have that option. So I decided to try the method recommended in the DronArmy chat - secondary foam and concrete slab. For the slab, I found a mold on makerworld https://makerworld.com/uk/models/44160-concrete-slab-mould-vibration-sound-dampening-base?from=search#profileId-634281

For printing, I used leftover filament that I had. To avoid clogging the extruder with dust - I used "a sponge filter".

And here is the form I ended up with:

Then I poured this with screed. Just in case, I went over the seams with tape.

I poured it with screed. But it was a bit too thin.

Screed Baugut

After a couple of days, I tried to lift it, but it hadn't dried yet and broke.

In this photo, you can see the waves from the tape on the inside. So for the second attempt, I left the tape only on the outside. For the second attempt, the weather was warmer, and I made a thicker solution. So after a while, I finally got this slab.

There is a height difference at the joints. A little sanding and everything is fine.

I found the foam in the DronArmy chat. I didn't want to buy a large piece and pay for shipping and extra material.

So I set all this under the printer:

The level of vibration decreased. But not enough for the monitors to stop shaking. But that’s more a question of the stability of my desk. So I will start working on this issue. And if I have the energy, I will take some vibration measurements.
