Would be interesting to compare the average time between mitre saw uses in a "session" then you can shrink or grow the 1 minute timeout to match your actual use. Adding a foot button for the floor sweep would be cool too.
really great stuff. a couple of suggestions if you are interested... one is that the dust going through PVC will build up a ton of voltage... like thousands of volts. I had issues with the sparks interfering with the electronics on my CNC during really long cuts. So you may want to think about grounding your PVC pipes every so often. You can look up dust collection grounding for ideas. Another idea is for your floor sweep. My guess is that you will occasionally kick that sweep sticking out with your foot or rolling carts/tools. But you have that perfect wooden workbench there so you could cut a hole for the PVC to go down into and then have the floor sweep end flush with the wooden workbench, so you would just be sweeping up everything underneath there with nothing to trip on. Thanks for the great ideas!
Another idea for the floor sweep would be to switch out the push button for something you can trigger with your foot. Who wants to bent down for a button when you can use a foot pedal, motion sensor or photo sensor? Or even RFID with a tag in your working shoes, so your mice doesn't trigger the system in the middle of the night
You should add one of those industrial switches with the spring on, for the collector on the floor. With one of those you could just bash the spring with the brush and have it turn on without stopping sweeping.
Great stuff Zach! Super approachable and straightforward. And thanks for sharing your code and 3D models! I'm going to have to add these automated blast gates to my todo list now.
For my system I didn't add an auto close of the blast gate when the dust collector turns off because you might risk burning out the motor in the dust collector if it has too much resistance even when winding down. Instead when one gate opens for a tool all other blast gates close if they are open so there is always an open path for the air to flow in the system.
Could always use the linear gates by putting a small pinion gear on the servo instead of a control horn and then printing a little rack to go along the slide part. This is a great design but I don't think I'd like the big triangular bit stuck on my wall as much as the linear slides.
I notice that you have a 2x4 under the platform next to the floor dust collector. Perhaps build that into the area under the platform so it's not sticking out like that? One other thought is to delay the blast gates closing by 10 or 15 seconds to allow the dust collector to spin down so you're not putting a hard vacuum load on the pipes and fittings.
I've watched way too many dust collection videos. Your 2 45° elbows are more efficient than a 90°...it has something to do with turbulent flow and fluid dynamics, but my engineering courses were taken in the 20th century and not used since, so I'll refrain from speaking authoritatively here. Cool video as usual!
Fantastic idea, and a very good realization. Iwas on my way to do the same thing, but with a linear blast gate, but your idea is better and more easy. I will replicate that. I've got some question: 1. what kind of wemos D1 mini did you take D1 mini, D1 mini V3, Pro, V4 ? 2. do you think it will be possible to add some led to indicate the statut of the blast gate like a green when it is open and a red when it is closed ? I've got some 12V LED, and I would like to use it, but I don't know how to add it and program it with the D1 mini. Could you help me for that ? Also could you provide a wire diagram of the connection for the Wemos D1 mini and the servo and the button ?
Your gates probably could've been kept closed with springs, and then momentarily opened via another method That way the system is always "closed" until needing to be opened
You could open the gates by having vacuum from the extraction control some pneumatic actuators, but then, the servos function very well, and probably easier to make.
Not watched the full video but I hope you're putting some sort of flame arrestor in there, all that plastic which can cause static and all that dust could be an explosion waiting to happen.
Actually, no. Search for "Grounding PVC and Other Dust Collection Myths". There have been no known fires or explosions caused by dust collection systems using PVC pipes. After reading the article, you'll find that common myths like installing a ground wire won't help, and that metal ducting does not prevent the dust from acquiring a charge. Lots of good information there.
Pretty sure that's been totally debunked by several sources, but who doesn''t want unsolicited comments from someone who admits they haven't even bothered to watch the video so they don't even know if their comment is relevant at all.
The second camera angle and not looking at the camera thing is really off-putting. It’s totally unnecessary. Also leave off the fake camera movement you added in post.
I would like to gently disagree. The second angle is fun and keeps things moving even for explaining focused sections. I find it entertaining and I like it a lot.

Oh and you should totally make one of those really nice extra dust collection pieces for your mitre saw. they are all over youtube

Even the CNC should keep the dust collector on for a while to empty the lines and not leave sawdust in the PVC pipe. Just a thought.
For the floor sweep, you could add a sensor that would be easy to actuate with a broom, like a break-beam or ultrasonic sensor.
@@blazer5154 That's an interesting idea! I hadn't even thought of that. Any idea that allows me to be lazy is a good idea
Or just a simple flap you can operate with your foot. Worked in huge international facilities and that's all they use. Keep it simple
@@bytesizedengineering Not nerdy enough and is it gonna turn on everytime you walk by? Do a proximity sensor between the inlet and your broom.
My Pop would have loved this project. He was a huge fan of New Yankee Workshop.
Add a microcontroller to your broom storage hook to detect when you use the broom. Have that turn on the vacuum.
@@flannelshirtdad I love this idea! If only I was disciplined enough to have a storage hook for my broom 😆
The miter station isn’t cooperating, it’s not collecting all of the sawdust. Looking forward to your solution!

Loved the video but can you please tell me the exact make and model of your camera so I can make sure to never get it?

@@JCWren Yes, I have totally considered doing that. There are a lot of little tweaks like that, that are pretty easy to adjust

Question. What 3d printer and filament type did you use to make the components? Another great vid.

You are better off with 2 45's rather than 1 90 just to reduce suction loss.

Is the camera operator aware of concepts like 'depth-of-field' and 'auto-focus?'

I'm not smart enough to know how to add fake camera movement in post. That is an actual human being holding the camera
