In all of the videos showing the Glowforge in action I don’t remember any showing the Air Assist port. (Might be wrong). Air exists the rectangular vent behind the head and shoots rapidly toward the front of the machine. Smoke circulation is such that it completely avoids the head area and exits the left rear of the unit.
This material test uses less than 40% of the current maximum score speed. Settings will continue to evolve as the S/W changes. I used a little $50 Polaroid Cube camera for the video.
Watching that it makes more sense why the air assist wouldn’t be pointed towards the back and the exhaust port. doing it this way creates a circulation in the glowforge that appears to clear the whole work area, or at least a large percentage of it. Very cool video.
So if you were doing small enough objects you could go higher because the air assist would never get over that part? (This sounds sorta like the nozzle clearance stuff on some 3D printers)
Good video. That reminds me. I don’t believe I shared this video publicly that shows the air assist scoop front and center. Not a whole lot of smoke gathering in the exhaust.
