Ouuuuuch.
That just means you're spreading
GLASS FIBRE dust throughout your whole shop as the dust goes through the holes in the 'bag'. A normal bag type dust collector will catch the big chips (which aren't going to get into your lungs anyway) while spreading the fine dust everywhere, and that's the stuff that will hurt you.
You could not pay me enough money to work near a setup like that unless I was wearing a P100 full face respirator 100% of the time. Glass fibres in the lungs simply cannot be good for you.
I machine G10 every day. The only way to do it safely is to plumb a vacuum system into your machine, with a nozzle right next to the cutting zone. The vacuum should at the very least be a 'HEPA' type, but remember putting HEPA on the box just means the filter media is HEPA, it doesn't mean the dust collector/vacuum has actually been leak tested and HEPA certified. A collector with full-unit HEPA certification would be much better. I use a 'dust cobra' from Oneida Air Systems.
The dust collector will not be able to pull in all the big chips, but they are not the issue as they will settle downward immediately. The issue is the fine dust and the dust collector will get all of that. As I said I machine G10 every day, usually for at least 2 hours a day, on my Fadal VMC. After years of doing this there is ZERO G10 dust under the way covers.
Here's some photos of my dust collection setup. The large loc-line nozzle is connected to an ABS pipe which is attached vertically to the spindle cover by magnets from McMaster. The pipe is connected to a hose which runs along the cable chain to the back of the machine and down to the dust collector. The dust collector is switched on and off by M-code.
The large loc-line nozzle is the dust collector, the small one is for air blast when cutting steel. They are never used at the same time, and the air blast is never used in a cycle after cutting G10. All G10 chips are vacuumed out using a HEPA shop-vac in between cycles. This machine always runs dry, no coolant.
The nozzle is kept as close to the spindle nose as possible while still allowing clearance for the tool-changer. It clears the tool-changer by 1/16" or so.
A side note: to cut G10 stock into blanks ready for the CNC use a wet tile saw with a diamond grit blade. Lasts 1000x longer than a chop saw with a carbide blade, and does not produce any dust.
Also, buy a respirator.
