Ish. It's a paver stone on top of a piece of anti-fatigue foam that I cut down to fit.

The rubber on the bottom of the X1C grabs pretty well and I never had an issue with it walking, but the added mass does cut down on the noise and vibration. I wanted the table to be pretty heavy as well. I didn't come up with it - it's a pretty common tactic for cutting down on noise for faster 3D printers.

I have pretty much the exact same setup, but used a rubber paver and concrete paver. The rubber paver is a little harder, but still basically no vibrations anymore.

Thanks. I'm going to try this. My wife will be much happier if the louder printing of the P1S I got is muffled a tiny bit.

The spacer he has is almost as important. The chamber gets really hot while printing and can cause problems with PLA or other low temp filaments, so the fan on the back fires up and can be really loud. You can swap out the fan with a quieter one, but printing the spacer allows the top to vent so you can set the fan speed to 60% or so without chamber temps rising.

I printed a 'muffler' of sorts for my fan. Basically a box with a zig zag patter going down inside and a piece of felt shoved in it. It's held on by magnets and works decently well.

I haven't looked at a muffler, but it's a good idea.

Regarding chamber heat, I still haven't quite dialed in my PLA settings. On really big prints, like a router template, I get some peeling in the corners (exacerbated by the chamber fan). Adjusted the settings to run at different temps, fan settings, dried the filament, all of which improved the results, but didn't eliminate the issue. Gonna try a smooth finish plate instead of the textured one that came with it.

I had similar issues with my Prusa Mk3 when I first started using it, but it was easier to tune out.
