I currently have most items ordered for my lowrider v3 so I am patiently waiting for those to arrive. In the meantime I am planning the enclosure for the CNC.
For 3D printers, rubber tiles remove pretty much all of the vibrations and reduces noise significantly. Does this apply to CNCs too?
The idea would be a sheet of plywood at the bottom, a layer of rubber tiles and then another sheet of plywood on top where the lowrider is attached too. Would this do anything or is that not worth it? The walls and roof of the enclosure will have foam attached.
I understand. But the spindle makes a sound that you can somewhat trap or at least reduce, right?
With 3D printers I noticed that the fans and stepper motors are louder than the vibrations when you stand next to it. Being in the next room, I no longer hear the fans or steppers but I do hear the very low pitched vibrations.
So I was wondering if the lowrider generates sounds like that?

I doubt this would make any difference. As Phillipp mentions, most of the noise comes from either the router, or from the cutting. Using a spindle instead of a router for the cutting does make a significant difference in the router noise, but spindles comparable to the common routers used on these machines are significantly more expensive than the routers. Also, I would shy away from using anything soft, like rubber, supporting a surface you need to be rigid.

I built my enclosure for my Primo and used foam board in an attempt to deaden the sound. IMO, the foam didn’t do well to deaden the frequencies produced by router and cutting. In addition, the foam traps heat, and on a hot day when running jobs, my enclosure was hot enough to warp a couple of the plastic parts.
I recently decided to replace the foam with acoustic panels. I purchased these, but have not installed them yet. I’m waiting for a bit warmer weather for gluing. I’ve also seen YouTub videos on DIY solutions. I used the idea of fabric outlined in this video when I made an enclosure for my air pump (air assist for the laser).
The panels you linked are similar to the ones I will get. That’s what I meant by foam panels. Out of curiosity, what did you think I meant?
Thanks for the tip! I see how a rubber layer could reduce rigidity. Definitely skipping that then!
My house is attached to a neighbor on one side and I am trying to take that into consideration. There are thick walls in between but I want to reduce the noise as much as possible anyway.
Often when “foam” is mentioned on this forum, they are referring to foam board like this. Foam board is currently what I have installed in my enclosure, and I’ve seen other posts where people are using foam board (or are planning to use foam board) in their enclosures.
