I am an engraver by trade. I run multiple CO2 laser engravers (Epilog and Universals) and they all have dedicated air assists to not only clean the surface while engraving but to cool the substrate. I have not read anything about how Glowforge deals with these issues. I have watched your videos and noticed a lot of surface flaming on the substrates you have been vector cutting yet there seems to be no burning and minimal smoke. From my experience the air assist would be essential in keeping smoke away from your lenses. Can you explain? Thank you.
Also can’t wait to get my hands on the pro model I ordered. The Glowforges capabilities are impressive.
