CNC Dust Collection part 1

I have been needing to build a dust collection hook up for the CNC machine. In this project I used a modified version of the dust shoe that is on CNC Router Parts web-page. With the help of Nathan at CNC Router Parts, we made a design for a dust shoe with two 4" flexible hose connections. My hope was that with suction from two 4” hoses, I could get away without using the brush attachment. But I have found that the brush helps greatly in catching the dust and helping it up into the dust hoses.

Frank one thing you might try to replace the brush material is some vinyl plastic strips like you see in cold storage facilities to let people and forklifts through. We did this with our cnc routers at work. Some plastic around 0.02-.03 thick works fine. wrap a piece around the dust collector and cut slots every 1/2" or so. I you only have some thinner material, use two layers and alternate the slits in the plastic. One thing is to not make the strips longer than the distance from the edge to the cutter or they may get sucked in and cut off :-) Especially when using a planing cutter to flatten the spoil board.

I've also seen someone use a piece of clear plastic from a bottle, but I'm not exactly sure of the results. Maybe just a 2-3" piece in front of the bit so you could watch it work.

I can see that working. I've made eye protectors from a mayonnaise jar, and drawer slides from clorox bottles (which is thin HDPE). So many reusable plastics out there.

I can confirm that this works- it's what we did at a local makerspace. The one problem we were having was it kept sucking in and collapsing, which wasn't a big enough problem for us to put effort into fixing. I's sure Frank can figure something out about that if he runs into that problem.

@We_Reddit 7 жыл бұрын

I can't help but thinking as i watch this that at some point the brush material may get stuck or pushed back enough in the piece that is being cut, and it becomes entangled with the bit. I suppose a single piece of a plastic brush will just get cut off, but wouldn't using a bigger piece like vinyl strips risk this kind of entanglement and damage to the cnc?

Hi Frank, the CNC machine I sometimes use has a big enclosure which is somewhat transparent and then an opaque shoe you can lower if needed. Both make it real hard to see what's happening so I decided to add a small camera inside the shoe. You can get a decent 1080p camera and a Raspberry Pi for very reasonable price and as a bonus you get CNC cam shots for the channel. You can take the bend out of your plastic parts by heating them with a hot air gun and bending by hand. Just go slow, and work out the correct temperature on scraps beforehand. Great videos, it really makes my day when a new one shows up :)

I've got a similar terrain map of Mt. Hood hanging on the wall of my shop. We made it on our CNC when I worked at OMSI. It was a proof-of-concept for a bigger project showing the entire Pacific Northwest and would allow the user to place different types of power plants around the area and would show how much of the Pacific Northwest you could power with those different combinations of power plants.

Funny. I have a clear brush made of transparent plastic material and was just thinking about replacing it with a bristle version. You can't really see through the plastic anyway clear enough to be useful, and I think I'm getting more dust escaping than I've seen with the bristles. That said, I'm new to all this and my plastic-skirt version is the only one I've played with.

Frank, Suggestion/Thoughts of a madman: Put your Y connection on the router itself. Run a single 6" flexible hose from the ceiling duct down to your router instead of two hoses. Make sure to have some sort of swivel mechanism on the ceiling hose connection as well, or have a secondary hold point as to not stress the hose joint itself.

Frank, always enjoy your videos. I have a smaller Shapeoko style CNC and had a dust boot which moved with the head and it always seemed to have problems. I got the Suckit Dust boot and you set the height for the dust boot and the cnc head can move independently. Works so much better, maybe you can design one of your own similar in style and it may function better as the hose stress on the head is taken away. Great video though!

Hi Frank, nice Video - as always :-). Two recommendations: 1. If you want to glue something to plastic try RTV silicon. I use this even on POM and it works. It's not super strong but keeps the magnets or the brush in place. 2. To see the router bit during the operation you can make a cutout in the brush. This also helps controlling the air flow. If the brush is all around, the air do not know which way to go and sucking is from everywhere. If you have a small cutout in the area of the router bit the air has a specific way to flow and helps sucking (especially with your suction power). Best Regards from Germany Alex

My suggestion is to see if there's enough room in the top of the dust collection fixture to have a Pi Cam (from a Raspberry Pi) and some LEDs stick through. Then you could monitor what the bit is doing in a web browser. You'd also have some cool footage.

Quick Tip: I was triggering my proximity sensor on the Z axis with my dust collection hose. The wire inside the hose was enough to trigger the sensor because it was dangling around the top of the Z axis. A small guard fixed it, but was a pain to figure out why it was stopping all the time..

Your projects are always inspirational. My $0.02 on this one: Also experiment with a single 4" hose shoe. Does the increased airflow from two hoses balance out the additional loss of suction from the increased size of your brush-enclosed area? My guess is no. The brush-enclosed area should be small for best results. You could actually use both hoses, but reduce down to a smaller brush area with a manifold--that would be sweet. The skirt needs to go all the way around and control airflow as much as possible to be effective. But, as suggested many times, an upper shoe cut from acrylic or plexiglass will increase visibility. Also, a making either the whole skirt or just a window region in your brush from a sheet of flexible clear nylon cut into strips will really help with the visibility. Cheers!

What do you think about making the holder from clear acrylic as a lot of people are suggesting in the comments? Possibly make the top part bigger in the front and be able to see the bit from above. It would mean less concentration of the suction power but the brushes stop the kinetic energy of the sawdust and the dust stays on the table. Or get collected the next time the router passes by. Thanks for the great video!

So, I have a dust boot for my X-Carve that is attached to the stationary part of the router carriage and adjustable up and down. This enables the brush to be at a fixed height over the workpiece and eliminates the tendency for the brush to affect the motion of the carriage. It does an admirable job of dust collection although I am not thrilled with the quality of the attachment/adjustment design. Just another thing to consider...

I guess if you have longer brushes (so they seal better to the workpiece) and leave a gap on each side of the bit, air should go in by the bit, pick up the dust and head out to the side to the hoses. That way you could see the bit in action. Also, as someone else mentioned, you could make the top out of clear acrylic or polycarbonate. Another idea is that you could drill holes and glue in a couple of white LEDs to illuminate the workpiece.

Great video Frank, thanks. The brush needs to be as long as the bit - maybe you could have separate brushes of different lengths? Re seeing the work - it's going to be difficult, making it out of clear plastic or adding a window is going to get dirty. The section of the dust collection head near the bit could be much narrower though, almost like a figure of 8 so the dust collection is at the side with a narrow section in the middle. You still won't be able to see the bit, but it will be more obvious where it is?

Dust collecting, one of my most frustrating issues in the shop. Last year, I thought that overarm table saw dust collector is on sale. That has to work great, can't be any worse then the current spray of chips from the 14" blade. Well, wrong. It does not work because you can't get enough suction flow at the end of a pipe. And flexible hose, just adds more restriction. In my case, I used a dedicated dust collector, with a short 8 foot piece of semi rigid 4" vacuum hose, to the reduced 3" pipe of the overarm collector. The optimal suction would be the vacuum impeller mounted right to the dust hood, moving the maximum amount of air. The other issue with the table saw collector, is the darn thing is in the way anytime the rip fence is within the dust hood size distance from the fence. Your overhead hose, I suggest to leave the 6" pipe size, as far down from your ceiling as possible to minimize the restriction from your 2 corrugated hoses, making the Y split as close to the Z axis spindle as possible. I wish someone would make a compact light weight motor/impeller for just these sort of collector issues where super high volume is needed. Thanks for the videos.

Hi Frank, I watched this video last week and an idea came to me that may improve on the brush and not visually obscure the cutting tool like a brush. If the brush were replaced with an air curtain it may keep the dust in and allow a clear view. I've worked with air curtains in large industrial plants and they are effective in keeping dust out of sensitive equipment, we used to take a clean compressed air supply and direct it where needed and it worked wonders. I could see a manifold like a copper pipe that has been shaped like the outline of the brush with air ports drilled along the bottom allowing air to hit the table and forming the curtain. Might work?

Just had a thought; while not all plastics are suitable for thermoforming, most plastics are in some way responsive in a useful way to judicious application of heat. If you have a scrap piece that's exhibiting this stress-bow I think you should experiment with heating it to relieve the stress. In an ideal world you'd heat it up to around 200~250F on a flat surface for 30~ minutes and all that stress would relax out without significantly impacting the parts dimensionally. The trick is going to be finding a low enough temperature to relax it without really getting it into the "workable" range where things might mush around. Looks like for delrin that's in the neighborhood of 180F; for Corian it's 300~350F PS, take the magnets out before tempering; heat can make them demagnetize.

@T70781 7 жыл бұрын

Based on some measurements I've done using a laser particle counter, I would guess that you were catching most of the fine dust (the dust that causes health problems) even without the brush. The larger bits have much more momentum so they require more air velocity to capture. The brush accomplishes that as well as bouncing them back into the air stream. With the large amount of airflow you have, you might be able to get by with a small opening for viewing. I attached my boot to the stationary frame so it doesn't move up and down with the spindle. That also allows a large opening in the center where the spindle moves through to see everything that's going on. Essentially, most of the air is drawn down through that center hole so you can see the bit but still catch everything. Unless you do a lot of 3D cutting that's taller than your brush, a boot that is held stationary in the vertical axis works better for most projects. I was going to design mine to mount either way but found that I don't need it.

Fun project... An idea I had a while ago while watching the trade-offs with dust collection on CNC machines. Could you build a dust hood that had it's own Z-Axis lead screw controlled by the g-code so it would move up and down with the "terrain" as the cut progressed to keep a near-contact air stream?

Regarding being able to see the bit, it's possible to mount a cheap webcam in the dust hood. If the dust collection does its job, it won't get dusty, they last a decent amount of time even with the vibration, and even when it breaks it's only $20 to replace it.

I think it might be possible to heat the PE to release some of the tension in the plastic. If you lay it flat in an oven and heat it up I'm guessing it will flatten itself. No more than about 100°C.
