DIY CNC Enclosure - Silenced & Dust Free Solution (Cheap)

This is an easy to build CNC enclosure that will provide silence and dust free CNCing. All the OSB was found at construction site where they were building a house. 2x4s were purchased but there was lots at the construction site in the scrap pile. Polystyrene foam board was left overs from a past job, which ended up free. I think it was about $8 a board or something like that. I found pink foam board in the dumpster at the construction site that would have worked as well, but used this instead.

106db coming out of the CNC router was quieted to 75db. Which is the tone of a normal conversation. I could have coated the walls in egg crate foam for even more silence, I found this to do the job and the price was right.

I am running a E3 CNC from Bobscnc. (Old CNC Model - No longer sold)

The fact that you care about bothering your neighbors earns my respect. Good for you. Subscribing now....

[geospectrum]

Good job, they are Decibels, not decimals though.

Interesting material choice with the styrofoam. Styrofoam is more for heat than sound. I think a good thick layer of it would be a good thing, but I would have supplemented the choice of materials to stop a wider range of frequencies. I like using 30 mil thick construction paper, the thick stuff, and use 2 layers of 3/4" sheetrock on each side, and you could put styrofoam inside that, and 3/4 plywood on the outside. You need some weight to stop sound. Also, you could put some odd shapes of styrofoam inside to create uneven walls inside so there are uneven reflections so there will be nothing trying to resonate. Maybe a layer of thick home insulation, or thick super heavy commercial insulation much better, and put that between the plywood and the sheetrock. The sealing to make it air tight is really important. Still a great job. Glad it worked out for you.

What's the heat like inside? Also not worried about fire/ flammable materials on the interior walls?

[DurandsDesigns]

Nice job I just made one myself. It helps a lot with dust and cuts the noise down as well. I use a security camera and wifi plug as well so I can shut down in the house if I see any problems.

[bartisticproductions]

Excellent video. Thanks for the speeding it up.

[RoseKindred]

Nice build, I do not have a CNC yet but learning about them. I would update this with one or two fire suppression balls because I am scared of it burning down.

[scaletownmodels]

Just wondering what a layer of eggcrate foam would do. You see it used in sound studios all the time to absorb acoustic reflections. Nice you care about the neighbors. I don't like to use my metal abrasive saw as it's so darn loud.

[wampumbiskit]

i like it other then the part i would turn it 60 degrees clockwise, so the end of the table is facing the door, just in case you want to mill like a larger sign into 2 steps with the door open.

[MichaelDavidHiltner]

Thanks for the chuckles! Oh, and the idea too!

[Cnthib]

Nice job, awesome ending.... If I would add anything to mine, would be a pull out drawer that the CNC sits on.

[gatorman]

Good job I want to know about the dust cover

I made something very similar, but I used egg carton foam for sound dampening. It started getting really hot inside, and I was worried that I'd spark a fire with all the little dust flecks floating around. I ended up attaching a vacuum port to one side and putting a small vent hole on the other to get the fine dust out. The extra noise from the vacuum didn't help, but I'd imagine that dust collector would have been a little quieter.

[MattJonesYT]

That looks great. If you caulk all the air gaps, especially with something like green glue, it will work even better. BTW egg crate foam does not sound proof, it is for reducing reflections.

[WubbaLub]

I did this with a cnc machine at work and noticed a ton of heat buildup inside. How is yours after running for a few hours?

[sitgesvillaapartmentneilsc]

wonder how it would be if the machine was un der load, thats the true reading you need to produce as that will be very different.

[usafgarza]

Great idea! I also have an E3 and need something like this. Can you provide the measurements? Also, I have a bit duster on the way, so looking forward to adding that! Thanks!

[SuperMouseDV]

Thank you for sharing this.. I will be building my own version very soon. I will thought make sure mine has a solid floor for the CNC to rest on..
Might make it 4-6 inches of insulation thick under it. (I have a Shapeoko 3 XXL not assembled yet) But like everything you did with yours. I might put
the laptop on its own shelf though.. Thanks for sharing as I wan to run mine at all hours like my 3D printers..

Where does all the dust go, do you have a vacuum on it? What size in the router.
