I got a axiom pro 2x3 machine, the axiom overarm dust system, and pro dust shoe

I guess i just need a dust extractor/vacuum

i was looking at the online rockler store because i dont know where else to look or what to look for
https://www.rockler.com/dust-collection/shop-vacuums

and when i get a dust extractor/vacuum i am not sure how i am going to make a air tight connection from the dust extractor/vacuum to where the end of the lower part of the axiom overarm dust system being that part of it is a large hollow metal pipe i guess i will use some tape

They make hose clamps for that.

You might want to check into the harbor freight 2hp dust collector for less than the Rockler unit would cost

I don't know much about CNC machines but I would guess they put out a lot of chips and dust (mostly dust).

Does the manufacturer give any recommendations concerning the requirements for a dust collector?

I'd say that I would definitely go with something that has a HEPA filter or a lot of the finest dust will end up back in your shop. Only HEPA filters will trap the finest dust, which is the stuff you want to eliminate most. It is the most harmful to you.

I wonder if a vac would move enough air to grab the volume of chips and dust produced? You might want to investigate what is necessary to pull the high volume of waste which comes from a CNC away and safely inside your collector.

Just a couple of thoughts. Generally I have bought dust collection equipment that I felt would handle more than I need it to do. The HEPA filters aren't cheap but will keep your shop essentially free of a layer of dust. Also, a collector which can't move enough air will leave a lot of the chips/dust at the source and possibly clog up easily. Again, I am not a user of CNC machines so don't know the specific requirements, but have learned about dust collection over a long history of woodworking.

I predict you will need to empty that small bucket pretty often. Once it get much more than half full, it will start sucking dust into your shop vac's filter, making it useless pretty fast. Consider going to a bigger chip collector, 30 gallons is good.

And, add a Dust Deputy to the top. It uses 2.5 inch hoses and will dramatically decrease dust getting to the shop vac. The Dust Deputy is going for about $50, a good quality drum will cost anywhere from $20 bucks up. You can use a metal trash can, but will have to cut an opening in and probably reinforce the lid. A plastic trash barrel will definitely require a reinforced lid, and you'll need to line the connection between lid and can with some kind of gasket and several bungee cords to keep the lid down. Some folks replace the plastic lid with a shop made one of plywood. Not a bad idea. I'm a fan of the Harbor Freight dust collection unit when it is on sale and you have a coupon--about $170 or so. But the shop vac might do what you want since you have the dust attachment with brush for your CNC. Worth a shot.

BTW, Harbor Freight flyer came today and the DC unit is priced at $209, with a 25% off coupon that brings it down to about $162 for the weekend.

If you can put your extractor outside!

I'm doing that, per Stick's suggestion. Have a covered, now enclosed space between my shop shed and office shed, and my 30 gallon chip collector, 5 inch Super Dust Deputy and Harbor Freight DC unit are all in there. The space is pretty well sealed and I'll be cutting a return air port so the clean air passes through a set of extra filters back into the shop. Turned into a complicated project since nothing is square or plumb.
