Yep,
Dust is BAD for lungs and bearings!!!
I wouldn't do this as a regular gig, that's what a wet CNC is for(and they are messy!)
One thing Brady mentioned was not to use compressed air(use vacuum) as air pushes dust into shop air and bearings. WOULD use an N95 or better.
Jerry,
Wet cutting without a constant flow of water creates an almost cement.
HAVE thought about carving some of my soapstone(Talc) with mineral oil, as mineral oil(or better using body oils like on my antique soapstone carvings0 is often used for finish.
