Stumbled on this video. Nothing to add but AWESOME ideas went into this!!!

Quality content right here! Please post more :) Thanks

Honestly your videos are really bloody good. Keep it up 👍

Look, I'm just gona flatout say it. I'm extremely jealous of you. I have had plans to do everything your doing, even the French cleat system on the wall but it's been a struggle trying to economically handle all of it and be able to put in time for these projects. All in all. Hats off to you, i had bought a canister filter for my harbor freight dust collector. Much better then the bag. You are on the right path. Like previous comments the reduction of airflow can still be reduced. There are alot of youtubers that go in depth of making a even greater system. I would even recommend having the vacuum motor close to the cnc spindle system and then connecting it to a main dust collection system. Being able to 3d print fittings, man. Your doing it and it's awesome that it's working out for you.

thanks for the ride

This is so nerdy, I love it. 🤓

Pretty interesting results indeed, dude! Fantastic work! 😃 But, honestly, even if the efficiency dropped by 50% it would still worth it. The bag is a nightmare! 😬 Anyway, stay safe there with your family! 🖖😊

Great data Preston! I would love to see the numbers after you have run a few cuts with the filters. Are the cylinders+cyclone that much better than the dirty bag? Only you can tell us!

Try reducing the diameter gradually to increase efficiency

Thanks for a very good video. I wonder if you considered the fact that the 5 stacked HEPA filters are filtering in the reverse direction to their intended design. I think that the dust particles are normally supposed to land on the outside of the filter media and not the inside. Did you have any thoughts on this?

That router hood is designed for the high pressure low volume shopvac not a low pressure high volume dust collector. Use a 3 stage central vac motor instead of a dust collector. You can pair that with a dust deputy for shopvac so. Then use a similar spiral hose sized for shopvacs as well. Overall it will be cheaper smaller and easier use.

Love your work. Will do your stacked design. What about the mount for the ShopFox?

Interesting video, couple of items of constructive feedback: 1) I believe you're using those shop vac hepa filters the wrong way. That is, if you think about how a shop vac is designed, the suction source is INSIDE those filters and the dirty air hits those filters from the outside. In your design airflow is going in the opposite direction (inside out rather than outside in) to what those filters were designed for. No idea how much that impacts your results but I can guarantee it does impact it negatively. 2) You say you might look at designing a new dust shoe in the future. Well, you're right that it is far and away the largest factor in poor airflow in the system. You've got your new 3D printer now, I think this should be prioroity #1! You've invested in the cyclone, but that investment is wasted without a redesigned dust shoe that doesn't restrict airflow, and a different filter setup that uses filters for the airflow to go in the proper direction. My .02 cents. All the best!

I would definitely alter the dust boot to make better use of the 4" pipe.

Jet (and others I'm sure) make dust collectors that have a massive scaled-up version of the sort of paper filter your using (they're a few hundred bucks but I think you spent near that on this filter setup...) anyway They have a handle on top that you can spin around and it runs something up against the inside of the filter to knock dust loose, It probably wouldn't be too hard to design a 90 degree angle pipe to go on the top of your filter stack that you could run a tube through, and then have some brushes or something attached to the tube to clean your filters, knocking everything into your filter trap, Id love to see another wind test with those filters plugged up after a few months of use

Which filters are you using?

Did you design the CNC too or was it from a kit?

Is the flow enough to make the cyclone work? Not sure if that needs a minimum or maximum flow to work

Thank you for the video. UNanswered: Q: How well does this collect DUST when cutting MDF & wood?? Isn't that the only IMPORTANT test / question to answer?? Please let us know!

About $70.00 in filters. How much Filament for the stack? I've been printing for 2 years now and I just want to make sure this is cost effective. PETG or better I'm guessing?
