Ultimate Soundproof CNC Machine Enclosure for Woodworking

I custom designed this enclosure myself to facilitate noise suppression but still allow for proper air flow to keep the tools from overheating. By using a custom baffle system this keeps the unit quiet and cool (ish). An Ultimate CNC machine enclosure!

Great job with your enclosure. I appreciate your time sharing on video.

[@BitnerBuilt]

Thanks Jason!

[@scruffysanta8442]

Very nice looking build and it seems to work very well. I applaude your addition of the fire extinguisher to the top. However, You really should also mount one in the area where your shop vac, dust collection as well as the power strips. That area could also be an area that would be a higher instance of fire. With all the sound proofing foam, any small fire is going to grow exponentially due to all that foam. Just a thought from an old retired firefighter. :)

[@BitnerBuilt]

Thanks for the tip! It’s good thinking

Thank you so much for this. I'm just getting into CNC, still shopping for the machine, and this answers my worries about a home shop for, not only noise, but for dust as well. Awesome and thank you also for keeping your videos free of the buffoonery, memes, and other attempts at comedy that so many try to incorporate. Well done.

[@BitnerBuilt]

Thanks! Trust me I’m a buffoon, but I hide it most of the time 😆 yes this will take care of the noise and dust 100% also look at the quiet line of dewalt shop vac, they are orders of magnitude quieter, it’s what I use now in this unit. It is big (negative)! But does its job

[@studiogerk]

Nicely done. I have a project along these lines in my near future and you've given me some ideas, specifically the baffles. My build is going to have another layer or two (sonopan and drywall, mostly because I have the materials already). I'm a bit tight for space otherwise I'd do an air gap as well! Given how well yours is working I think that would be overkill. I just need the same sort of thing as you, not perfect silence. Thanks for sharing!

[@BitnerBuilt]

Yea the baffles work well and don’t have to be huge but the more turns the better

[@gjforeman]

Very nice CNC system. My CNC is on a cart with drawers, but the enclosure so far exists only in my head, and now I'm weighing incorporating some of your ideas. Thanks.

I watched your "Ultimate French Cleat" video by chance. 3/4 of the way through I thought to myself, this guy would make a great CNC machinist. I have been in the trade for over 20 years and the last 6 as a CNC applications engineer. Your attention to detail definitely fits the CNC machining trade, and then here you are after I subscribed I see you have a CNC router video. I am happy to have come across your videos and as a metal machinist, most woodworkers I come across think they have attention to detail but I know they wouldn't make it in the metal working side of CNC machining. I have the inverse problem of working with ultra tight machining tolerances and complex machines, and not being able to find a woodworking channel that matches my level of OCD. I think I have found it. Also, in that French cleat video you did, around the 24 or 25 min mark, be sure to replace that stud where your kids measured their height before you cover it up with drywall, and keep that piece of wood for a special project you can include it in.

[@BitnerBuilt]

Oh very kind of you Matthew! Yea my thoughts are constantly take up with ocd organizing and finding the most effective way to get everything in the shop as effectively as possible lol. Your completely right about the stud, honestly I’m going to keep the basement exposed until we want to move at some point, I have too many toys there to empty and proper finish it, thanks for the sub!

[@YuvakTuladhar]

What a nice enclosure. You have thought about lots of details. Amazing! I don't have much problem with noise because I will be using the spindle and the 1.5 hp is in the closet next to the CNC router but I do want to have a see-through thick plexiglass enclosure from three sides just for safety reasons as I have kids coming sometimes. Also, I like the remote system you have installed. Thank you. I like the camera idea too.

Well done. I've been thinking of jumping into CNC, but hesitant. I'd appreciate more content about how you incorporate it into everyday woodworking. Despite the fact you're a damn yankee, I still subscribed.

[@BitnerBuilt]

Haha thanks Beau! I will add that to my list and get a video out on that soon great idea! One great example is I made my standing desk video two days ago and while making the video I was thinking about man I really need to make this thing cordless with the battery. And I figured a solution right after I finish the video. A few people also commented about that! I already had, a battery converter for another video that I’m gonna do so it’s being re-purposed as we speak. It has a very small little button that would be a pain in the butt to cut out with a jigsaw so the ability for me to take some calipers and measure this buttons dimension, and have the CNC exactly make a hole that will be perfectly square, and exactly the size that I need where I need is awesome. That’s a five minute process. That’s going to give me a perfect result over if I did it by hand.

[@joeygleason8222]

Awesome video man, so many great ideas. One question though, could you go into a bit more detail on how to construct the baffles? What material is used, exact design, things of that nature. Having a hard time picturing exactly what a cross section of the baffle looks like. Keep up the great videos!

That cabinet is next level! You've got a lot of cool ideas going on there. I don't think I would have ever thought of fire suppression, but it makes so much sense! Thanks for sharing. How long did it take to build?

[@BitnerBuilt]

Thanks! Prob 2 days, I had it all planned out prior to building. Now I after 2 yrs with it I would say the shop vac area you want to use in line vent fans, more powerful than comp fans. I had a shop vac die because the heat in the compartment got too hot recently. The cnc area though stays max 91ish so that one’s fine!

[@marlontruscott]

..I suppose you could always put dynamat with the foam on top for sound deadening..

[@BitnerBuilt]

Oh that’s an interesting product, hadn’t ever thought of that of car noise insulation before, cool tip

[@douggreen1283]

Really like the video, I'm working on designing something similar (I hope) for my Onefinity Journeyman. Did you add buffer space when building to account for the foam, lights, etc you wanted to include? Or build to size, and squeeze everything in? Thanks!

[@BitnerBuilt]

Thanks! I accounted for the baffle otherwise I left a 2in gap around the perimeter. Part of me wishes is that I had left a little bit more space but at the same time, it’s a huge enclosure that takes up a large amount of space in the shop so on that note, I don’t want it any bigger 😂

[@rickpapineau2704]

Hello, Nice compact soundproof design you made . I agree the sawdust is going to drop every time you lift open that door, so when I make mine, I will have to change the lift open to fold down and be removable, which would also "pass thru routing as well for the ability to vacuum without covering the tool draws with saw dust. Just to clarify, you glued the grid to the at the bottom and sides, but left the top free to "flex" "not glued, which supports the final MDF layer which the router table rests upon? My understanding of tortion table is only one side is glued to the grid.

[@BitnerBuilt]

Thanks, on a torsion box of both sides are glued to prevent any flex and torsion. What I did in this design was make a poly glue torsion box as the base that the machine was in slid in upon onto two layers of MDF, so literally my entire machine can slide out of the enclosure if I need to, but the enclosure itself is perfectly flat to give it the proper base to sit upon

[@rickpapineau2704]

Thanks for clearing that up. Due my age, I may use1/4 thick material to reduce the weight of my torsion box, and just use one 3/4 inch MDF layer to mount my CNC router on.

[@sandrarattray1202]

How do you like the Longmill? I’m in research mode for a CNC and this one is on my list.

[@BitnerBuilt]

Hi Sandra, I have zero complaints and have been told by much more serious cnc owners that I chose well for the price range I was looking at. This is my first cnc and I wanted something that was not bottom of the barrel but decent quality at an "affordable" price. I would get their newer larger version as it has come up many times where I just needed a little bit more room.

[@ryana5359]

I like you build and your channel, you got a new sub from me. I am mimicking you cabinet for my Longmill MK2 48x30. I do have a question with your electrical load, does all of your power needs on one circuit? Looking at the amp load for the shopvac, makita router, and the longmill push over 20amps at max which doesn't include computer, lights, and fans. Do you have any issues with your setup?

[@BitnerBuilt]

Cool, thanks! So I originally had it on 2x15 amp breakers but I’ve had everything on 1x20 amp breaker for about a year now and it never trips. The one thing that I did do was plug the shop vac directly into the outlet.(after the remote plug to kick it on and off) and then on a power strip, I have the computer Longmill router lights. Most power strips are only 15 A so I figured putting the shop vac on there would overload it at the power strip

[@WoodenRoseWoodcraft]

Great video! Glad I found your channel. I'm in the process of planning my enclosure because I'm also in the shop late. Roughly how much money do you have in you build?

[@BitnerBuilt]

Thanks! I would guess around 700-800 for the enclosure lights remote foam blankets castors, drawer slides monitor arm, cables and pistons

[@WoodenRoseWoodcraft]

This is my something I do on the side right now but hoping to make it bigger. Can't wait to sell enough projects to justify price of building one like this.

[@aaronvonkreisler2586]

This is really awesome! How big of a difference do you think the baffles make? Wondering If I can get by without them or if they really are necessary for this level of quietness

[@BitnerBuilt]

The baffles are for quiet air ventilation. If you had holes in the top or side for air flow but no baffle your noise reduction will be a lot more negligible. Your only other option would be to have no air ventilation holes in which case you would have very good sound suppression but if you run that machine for a long time you’re going to overheat it, if you’re gonna do that, I would recommend putting the “brain” of the CNC. Outside of the enclosure, and running the wires in through a hole.

[@aaronvonkreisler2586]

@@BitnerBuilt Thanks for the reply! Sounds like I need to take a shot at the baffles. Another question for ya - It seems like everything is plugged into the remote outlets which are then plugged into a power strip, and I'm guessing that strip is plugged into an outlet directly or an extension cord? I'm going to buy all of that and do the same setup, but not sure if I need to worry about daisy-chaining since I will need to connect the power strip in the dust-control area to an extension cord (also know nothing about electrical 😆). Any thoughts on that?

[@BitnerBuilt]

@@aaronvonkreisler2586 I have one of those long power strips and then each of the remote outlets are on one of each of those. That then has an extension cord on it running to the outlet. here's a link to the strip I use and I have it inside the unit underneath where the shop vac is so it being centrally located everything can plug into it. amzn.to/3NqZzh1

Great build...I have wanted to use one of my Macs on my Longmill 30x30 as well but am having trouble finding Mac CNC software. What Mac compatible software do you use??? I guess I could run windows on the Mac?? Just curious. Thanks David Rodwell Winston Salem, NC

[@BitnerBuilt]

There are a bunch of web based versions that work so you can run it on Mac or practically anything else. I use easel and I run it on chrome (safari has some issues)

[@kenpoist7]

Have you experienced an additional heat build up with this enclosure? Nice informative video.

[@kenpoist7]

Sorry, didn't wait for the video to show the ventilation.

[@BitnerBuilt]

Thanks! That’s why I have the air vent baffles to keep it from building. It definitely does get pretty hot though in the shop vac cabinet if I’m running it for more than six hours. I had it going solid for 12 hours the other day so we opened up the back cabinet to let it cool down at one point for that back area. I’m probably going to replace the computer fan with more of a blower just so I’m forcing cooler air in there.

[@enduringpromise]

Thank you for sharing. Honest question... I am thinking the amount of air flow required by a Shop Vac would exceed the ability of the computer fans. My thought is that the computer fans are actually restricting the air flow. Your thoughts?

[@BitnerBuilt]

So the hole size I went with is 4in (fairly large) which I feel accommodates the flow enough, I would bet the fans themselves aren’t accommodating the push but the suction action itself is helping to move the air along as well. Even if the suction was overpowering the ability for the fans actions it’s still causing in and out action just due to the pressure of the confined space.

[@joeygleason8222]

One more question watching this back now that I'm actually building my enclosure! How are you grounding the wire that's wrapping the dust collection? I believe it needs to go to a ground in a wall socket but you don't just stick the wire in there right?

[@BitnerBuilt]

You can put one of the round loop attachments that crimp on the end and then I slide it on one of the outlets neutral bar that plug in in the unit. It’s unorthodox but it works

The fans that I used are 4” computer fans, these are good for the main cnc area. For the shop vac however I have swapped out to 4in in line fans to force more circulation as that was the area that would get the hottest. I will link those below. As the fans are 4in I make the interior of the baffles 4in. I will like a video where I show an open baffle. kzbin.info/www/bejne/jIOZdXmZopVlsKM amzn.to/3VaKVi5
