Hi all.

I have an old industrial CNC machine from a bygone era that I decided to repurpose for milling PCBs for another project of mine. While searching around forums for best practices i saw some posts saying that the dust created from milling the fiberglass board is quite hazardous, and dust collection and filtering is a must.

I've only just got this machine running, I haven't actually tried to make a proper PCB, I just used one of the boards for playing around with etching letters into, but reading about this has made me gun shy.

So my question is, should I be making or buying myself some sort of dust collector before I go any further into this? Is the risk that severe? What about an enclosure?
