Robert, Effective air-assist does indeed do all those things – it suppresses flames, helps with clearing debris from the kerf, and keeps smoke/soot from attenuating the beam while also protecting the lens. It clearly helps during most cutting operations but is often not needed/desired during engraving operations. But the key IMO is that it needs to be both effective and controllable… strong when cutting, minimal when engraving, and directed properly into the kerf regardless of the direction of …

and is working quite nicely on 3mm birch ply at 180 mm/min, 100% power, and a single pass.
