The dust extractor can be seen on my machine photos. It is basically a hose that is mounted in front of the spindle which is connected to a shop vac.
I have seen similar setups in other threads that used bristle brushes in a perimeter around the hose and bit that help to extract more dust but I didn't like that they block the view of the work being cut.
I have cut mdf plastic and aluminum for many hours and a simple dust extractor like mine works great at extracting small airborne dust. I have terrible allergies and just a tiny particle of dust in the air causes me to sneeze and have a reaction but i never had any troubles while the dust extractor was running. Lots of larger dust particles cannot be sucked up and will fall close to the machine (within a foot or so) but i just vacuum up my mess afterwards and its not bad.
I can tell you that without the dust extractor turned on there would be dust collecting even 20 feet away from the machine.
ps: deleted the g-code from my sign but i will try to make a newer one for you.
