Using a CNC router is a dusty business if your material of choice is wood. Sure, you can keep things tidy by chasing the cutter around the table with a shop vac, but that sort of takes the fun out of having a machine that can make cuts without you. The big boy machines all have integrated dust collection, and now you can too with this 3D-printed CNC router dust shoe.
Designed specifically for the X-Carve with a DeWalt 611 router, [Mark Edstrom]’s brush is a simple design that’s almost entirely 3D printed. The shroud encloses the router body and clamps to the mounting bracket, totally surrounding the business end of the machine. The cup is trimmed with a flexible fringe to trap the dust and guide it to the port that fits a small (1-1/4″ diameter) shop vac hose. The hose is neatly routed along the wiring harness, and the suction is provided by a standard shop vac.
Files for the cup are up on Thingiverse; we suspect it’d be easy to modify the design to work with other routers and dust collectors. You might even find a way to shroud a laser cutter and capture the exhaust with a DIY filter.

Wood working is great but it can certainly get the shop dusty. [BigD] is a wood worker and needed a way to keep his shop from getting super dusty while sanding or routing. He ended up making a pretty slick dual-use downdraft table with a hidden filtration system.
The table’s frame is made from standard 2-by dimensional lumber you’d likely see most shop tables made from. It was built so that the top of the table would be flush with the table of the table saw. This allows the down-draft table to also act as an out feed support for the table saw, making it easier to cut longer pieces of wood.
To allow airflow to pull any generated dust down, a plethora of holes were drilled in the table top. Down below are a couple sealed chambers, one for the incoming dust and one for the air blower that creates the down-draft air flow. The two chambers are separated by a pair of filters which keep the dust from being blown back into the shop. A little door on the side of the table allows access to clean out the accumulated dust and debris. Now [BigD] can sand up a storm on his down-draft table without breathing in a sapling worth of dust.
CNC machines are great at churning out custom parts, but they tend to make a mess in the process. [Darcy] has built up his own CNC dust collection rig to collect the dust and keep his workspace clean.
To capture the dust, a custom dust skirt encloses the cutting tool and directs the vacuum. This was made by gluing acrylic parts together, creating a box that contains the dust and provides a connection for the vacuum system.
For $1, [Darcy] built a cyclone dust extractor. This spins air around in circles, causing the dust to fall to the bottom of a container. The result is less dust reaching the vacuum, and much less money spent on vacuum bags.
Since the vacuum makes quite a bit of noise, a muffler was needed. This is just a simple wood box to contain the machine. It can also be used to vent the exhaust outside to further prevent polluting the workspace.
While we’ve seen some similar builds in the past, [Darcy]’s design could be helpful for those looking to build their own system. He also gives us a video which shows the effectiveness of the dust skirt, which you can find after the break.

Not long ago the Shapeoko 2 came out. In case you missed it, the Shapeoko 2 is the 2nd generation bench-top CNC Router of the namesake. All axes roll on Makerslide and v-wheels. The X and Y axes are belt driven, power is transmitted to the Z axis by lead screw.
As with most products, there will be people who must hack, mod or upgrade their as-received item. If you are a regular Hackaday reader, you are probably one of those people. And as one of those people, you would expect there have been a few individuals that have not left this machine alone.

CNC Routers are great. If you’ve ever used one you know this but you also know that they will cover the machine and everything around it with a layer of dust. It is certainly possible to use a shop vac to suck up the dust coming from the router, however, the only problem with that is the shop vac’s filter will clog with dust and lose suction, defeating the intent of your vac system.
[Mike Douglas] was ready to step up his CNC game and decided to make his own dust separator. This design is extremely simple and only uses a couple 5 gallon buckets, a few PVC fittings and pieces of wood. To keep the cost down and the style up, the accompanying ‘shop-vac’ is also made from 5 gallon bucket with a vacuum lid. The project is well documented so head over to his site and check out the build process.

[Darrell] made his own cyclonic dust separator which connects to a shop vac. We’re amused by his poke at Dyson’s marketing machine where he mentions that the ads say it took years to perfect those vacuum cleaners and he managed to put his together in a few hours…. from trash/recyclables no less!
Two mini-kegs are used as the separating vessel. The only other parts are some PVC plumbing fittings which help to direct the air and give him a way to attach the collector to the shop vac. The top keg is where all of the magic happens. Air and debris is sucked in through the hose coming in the side wall. A 45 degree elbow directs it downward and to the side, which starts the cyclonic action. The shop vac is attached to the tube in the top, with a cylinder extending into the keg. The spinning air must make a sharp turn to get into that cylinder; it’s at this point the debris drops out into the lower keg. See for yourself in the clip after the break.
This isn’t the first time we’ve seen dust collectors that use this concept. [Darrell] pointed out this one made out of plastic cups, and this other made from a 5-gallon bucket.

We’ve been following [glaciawanderer]’s CNC build for quite some time and he’s recently added a few upgrades to make for an even more interesting machine. He’s been trying out new bearing blocks, anti-backlash nuts, and z-axis plates hoping to get some improvements. In the case of the bearing blocks, he went back to the older style because of the added safety and smoother movement. The final addition he made was a dust collection system. It’s just a couple support hoops and duct tape, but it should keep dust out of the threads and rails.
