I am a complete noobie at this stuff, so please forgive me in advance for dumbness. I just got a k40 laser engraver and after setting it and making an engraving on a piece of luan plywood. I discovered that anything more than 10 pct power promptly set the wood afire. I think I need one of those air assist hickies.
Do you think I can just rig the hose of a air brush somewhere near the lens to blow on the workpiece, or do I need to route the air flow through lens nozzle. I can see one advantage to the latter in that it could help keep the lens a little cleaner. But my main thing right now to just blow away the flames and smoke.
Any advice is appreciated
