No Boot Dust Collection on the CNC Router
Вставка
- Опубліковано 24 січ 2018
- This dust collection is not your typical dust shoe installation on a CNC router. I don't intend to collect all the chips, and I don't want to hide the cutter from view.
This might be better titled dust 'extraction' as my intention is no to collect all the chips, but to clear pockets and slots. I am tired of holding the vacuum.
Power Tail: Power Tail is not longer available. This is a comparable device: : amzn.to/2Bj8o4f
In the end I wound up using this: amzn.to/2Dr5PPA
You can buy individual pieces too:
loc line: amzn.to/2n0E3CB
nozzle: amzn.to/2DtdFIg
vac adapter: amzn.to/2DzFDFz
Vacuum I'm considering: amzn.to/2DWi0F0

I now also recommend including a cyclone separator like this: amzn.to/39dZ4DE
You can find other things on my Amazon page at: amzn.to/3kZzDb6

I see why you like to watch the cuts, it's a satisfying view of work being accomplished. It's enthralling.
This was an awesome video. Excellent topic, good lighting, nice camera angles, and clean audio. It's a home run.
Thanks John. I am no cinematographer, so knowing that it came across well is appreciated. ~P
Where did you get the blue and orange hose as the better solution??
Could really use one.Thanks
Also as a tip use an SCR as a cheaper and heavier duty alternative to the Adafruit switch. Kyotto makes AC and DC up to 120 amps and up to 240 AC and 100 Volt DC.
3-32 vdc input signal @ < 10ma
Thanks
Dust extraction can be a tricky topic... I am like you...Keep my dust collection off most of the time so that I have a clear view to the spindle (unobstructed) mainly because most of my work is quite small. From time to time I will switch on the Jet to clear profile toolpaths so I don't re-cut chips and burn up/overheat endmills...I also do that with squirts of compressed air. Funny how you feel in control when you can see the spindle and cutter doing it's job lolol... My personal take on this is do what you feel comfortable with...Side Note: The only time I have a dust shoes attached permanently is when I cut any engineered materials that cuts mostly into fine dust like MDF and sometimes ply... Love the outtakes...that keeps it real :)
My end game I'm going to try a combination of suck and blow. Sort of like a broom and dust pan kind of approach.
good job, very informative.
Great job, Preston! I didn't know they made LocLine that large. I've got the dust shoe coming for my little X-Carve though. With all of the CNC machines around I have to keep the dust down so it doesn't gum up the ways. I also got one of the little relays with a 4 plug connection so I can have the controller turn on the spindle and vacuum at the same time. Hoping the 15A is enough for it...
Hope all is well and loved the video. It's definitely real life.

Thanks Tom. I understand with all your machines in a shared space. My mill and lathe are in a separate room so I can get away with a little more. Glad you enjoyed. The next video is less eventful. Take care. ~P
Does your machine use an Arduino for the controlling?
I agree entirely - you surely want to see the cutter engaging. Frustrating that clear plastic gives refraction of light as I do want to remove all dust so it may have to be a wide circular acrylic plate with brushes on the perimeter. But nobody seems to have come up with the perfrect solution to max dust removal whilst retasining max curtter visibility.
Just a heads up on the cheaper AC/DC control relay, from Digital Loggers. First I am not knocking the product. In fact their support team is excellent. However, if you are using a heavy duty dust collector, it may not work for you. Mine draws 15-20 amps at start up. This was enough to trip the built in current protection. If you are under the 12 amps it would be an excellent choice. Very easy to setup. It works great for turning on the light and spindle coolant water pump.
My friend you can make dust shoo by using plastic glass if you want to see the bit while running..
Good remedy for chip evacuations.
Have another question if you please.
I just recently picked up a “custom” built CNC machine and I see that your spindle clamping mount has the same middle cap screw that doesn’t fully seat into the threaded hole… just like mine. Is that screw for accessories or…. ?? That just the way it is?
Always have enjoyed your past builds and updates.
Many thanks.

Being able to watch the cutter is good, so many dust collection systems get in the way. Some 3D printed parts would help out in a number of places here, such as adapters for hoses and various mounts and adapters.
I have added the compressed air nozzles now. First time I ever had a use for 3d printing.
@@sbirdranch Like any tool it is hard to understand what it is good for until after one has used it awhile. Not everyone has the same experience, but I've found that I make several new items a week with my 3D printer and many of those are fixtures, tools or tool storage and organization. Being able to conjure a 3D idea up in OpenSCAD (free design software), 3D print it (to a few thousandths accuracy, and with very little of my time required), and start using it in a few hours is pretty amazing. Aside from making custom brackets and hose adapters in this case the dust collection head could be custom made to suit the router. Custom holders and trays for tools are handy and organize tools better than random storage. I make spacers with exactly the right external curves and internal cable tie channels that I could not make any other way. There are many types and colors of plastic that can be printed, and the raw material is in convenient rolls, one doesn't need to find a piece large enough or make a trip to the store to get material as is required for CNC cutting. The amount of plastic used can be very efficient with essentially hollow or various honeycomb internal structures. I never guessed at the variety of uses I have found for the 3D printer. It is also useful for making prototypes that later will be cut with CNC for fit testing and verification. Quite a few CNC routers are even built with lots of 3D printed plastic parts. The printer is not large and very quiet and dust free so it doesn't have to be relegated to the garage or shop, which is especially nice in the winter. :)
@@alanb76 That is a lot of good ideas. To be honest I have put off 3d printing for one more reason. Historically they have been very fiddle and I just didn't want another thing I had to budget my time for. I have a good friend that keeps up with that tech and occasionally I ask about them. His last purchase (compared to his previous) is cheaper, faster, and better. Those are all good things. So at the risk of thinking about it further I will ask....what make/model do you run? ~P
@@sbirdranch I started with a Lulzbot Mini, ready to print right out of the box. Now I'm using a Prusa Mark 3 which I got as a kit but can also be purchased ready to go. Both of these printers are open source and have good support both from the vendor and from the user community. Either would be a good first printer. I had purchased a kit years ago and it was a project that never quite completed, these are well beyond that. The cheap clones often need fiddling and upgrades. If you've already mastered a 3D design program that will produce files for 3D printing you're ready for it.
thing tubber radiator hose and two hoseclamps should work on getting the two hoses to connect
you could make the dustshoe out of clear plastic , you still be able to see way happens
I finally found the right connector that snaps into the last ball link. Good idea though. ~P
If you don't want to use a dust shue you might consider fabing up an enclosure and setup a cross wind extraction system. This is where you draw air from the front to the back or side to side whichever works best for your application. The design has to be right in order to concentrate airflow across the waist board. The main problem is CFM, you need a ton of it to make that sort of system work. I have a small CNC system that I have done this to and it works fairly well though I also run a dust shue in conjunction with it. I'm running a two stage Grizzly moving 750 CFM through an enclosure measuring 30L x 24W x 20H. The other key is air velocity! This is where the design comes into play. The inlets on the enclosure have to be the right size in order to speed up the flow through the enclosure to remove the chip from the waist board and the project.
That is an interesting idea. I have found that in some of what I cut, being more aggressive give a better chip and less dust. No size of cut helps when running in MDF that is for sure. ;) ~P
@@sbirdranch MDF is a dusty process which I have found that more CFM to the dust shoe works best!. Fine dust like MDF does not have that much mass therefore it does not require a lot of velocity to capture it. The supply to the enclosure has a 4" x 2 1/4" split.
I have a dust sweep at the bottom back that serves as the collection port which is controlled by a blast gate, the more I close it off the more goes to the shoe yet it still pulls air through the vents in the enclosure!
The vents are positioned strategically at the front and sides so they clean the gantry rails and waist board while making things a lot quieter all at the same time. The trick is calculating the right amount of opening and size of the opening for your vents to equal the amount of volume of air you can move through the intake hooked up to the machine.
I would like to know the lnk of the breakbord where can I buy it and if it comes with USB for mach 3
Here is a link to the exact board I am using: amzn.to/2Jhr2yG
I have the bulk of my components in an Amazon list here: a.co/fl2VO8N
It is being driven by a Warp9 Parallel smooth stepper board (see list). I know they make a USB smooth stepper also. I don't know if CNC4PC makes a USB version. Good luck.
LOL sorry for texting you over and over ... great vid
Terry2theGremlin It wasn't you :)
Great video and ideas, what is the blue hose called?
amzn.to/2Dr5PPA
It is called loc line. The same manufacturer that does coolant nozzles etc.
There are more links in the video description for individual pieces that may be cheaper to purchase than as an entire set. ~P.
Great video... I did a similar setup using a harbor freight single stage dust collector hose with a floor drain and hose (no where near as clean of a set up as you have). I mention this because my setup gets almost all of the chips. Why... Assuming the suction is a better... maybe something to consider for your setup. Do you know of anything 4 inch similar to the loc-line? Thanks for the video ... I am going use some of your ideas to improve mine.
jnbff10 so the floor drain is your inlet? I bet that dust collector moves a ton of air. I have a small-ish dust collector from Penn Station that sits at the other end of the machine and is hooked to my bandsaw. I could use it but didn't want the 4" hose. I have not seen a loc line style hose in that size either. ~P
sbirdranch I am not sure it’s a drain. I picked up in the plumbing section with other PVC connectors. It looks more like the rectangular end in the dust collection kit you have. I have it mounted similar to what you have but using several wire ties. As you said I want to see the cutter doing the work.
I think THOR would be happy to see how you manage your hammer at high speed :-)
I like watching the drill bits wander away on the bench as he power hammers the metal strip. +1 for informative and well shot. Thanks for sharing
With CNC Routers you need lots of suck OR, a little blow. I'm like you I don't want to cover up my bit and I want to see the work being cut and for setup, so a dust boot is a no for me. I don't care about getting chips on the floor or my machine, that's what its for. I do want the chips out of the pockets and not to have my cutter bit cut them twice, so they need to go as fast as possible, So for me It was a air setup with controlled puffs every 10 seconds of air directed at the end of my bit. It removes and chips/dust from the bit and keeps the work/pocket clean.
So is the vacuum blowing on it or vacuuming up the dust? You said you were going to use it like a blower and then the text message came in and killed that train.
The vacuum is pulling the chips out. I mentioned using compressed air to blow as well, but did not implement that in this video. ~P
where did you get the blue hose
Links are in the description. ~P
Was sitting here eating popcorn when i had a thought about your CNC Router i watched yesterday. Why don't you use a down draft table under the work, then you could use low level air pressure to evacuate the chips from the cut without spreading them all over the shop.
Found this down draft table build. ua-cam.com/video/QWTZNpcC2Eo/v-deo.html Some plexiglass side shield would help keep the larger chips over the table.
A local cabinet maker evacuates his chips/sawdust, through a six inch duct, to a sawdust pile about 20 feet from his shop, in the edge of his cow pasture.
Interesting concept. Definitely something for the fine dust like when cutting MDF. I have a small 4" dust collector at the end of the table I am trying to figure out how to integrated. Maybe this will give me some ideas. Thanks for the link ~P
