First of all want to say thanks for the help I have gotten here. finally got my replacement laser up firing and cutting after a miserable summer replacing my first laser after it burned down. Folks here made things much less miserable than they could have been.
Now that I have it running I wanted to get help with controlling the flaming I see happening. Cutting 6mm cork with a 100Watt RECI running at speed = 20 and power = 72%. The lens is 18mm diam by 80mm focal length. What this means is that the short laser head is a good 5cm off the surface of the cork when the lens is focused on the surface. So, although i still run it, it seems unlikely that the air assist is doing anything. The cuts are sufficient for my needs but you will see in the pictures that there is a lot of flaming on the surface during cutting (as evidenced by the partially charred surface). Cutting cork, for those of you who have not done it, is tricky and get trickier as it gets beyond 3 or 4 mm.

So, I would like to avoid burning down this one as well and would like to figure out what is causing the flaming, whether there is any way to improve the air assist to improve cutting and any other thoughts that have not occurred to me.
