Found this wood toxicity info:

And this about wood dust:
http://billpentz.com/woodworking/cyclone/index.cfm
"Our particle counters show many small shop activities especially woodworking even when using hand tools that make no visible dust make huge amounts of invisible fine dust compared to how little it takes to harm our health. Fine dust is so light that normal room air currents blow the fine dust all over before it can be collected unless we suck in the air from all around the working portions of our tools which is such a large amount of air that it takes just over three times more air flow to collect fine dust than it takes to collect heavier sawdust. Most shop vacuums, air cleaners, dust collectors and cyclone systems barely move move enough air to collect visible sawdust so they miss collecting much of the fine dust. Worse, in spite of advertising claims most small shop dust collection equipment comes with open filters that freely pass the unhealthiest invisible dust. Wood dust last years unless it gets wet so shops that vent inside quickly build up dangerously high amounts of invisible unhealthy fine dust that also contaminates all attached areas. This is why most fine dust exposure comes from fugitive dust which is previously made dust that escapes collection. Our particle counters show most even very clean looking shops that vent their dust collection systems inside build up so much fine invisible dust that just walking around without doing any woodworking stirs enough dust airborne to fail an EPA air quality test.

Soooooo…my cnc is in my apartment. Guess I’ll be sticking to machining metal and plastics from now on…
I’m also going to assume that Renshape has the same problem as wood.
What about wax?
