I did 95% power of my RECI Z4 100 watt with 2 inch lens on 1/2 inch thick MDF with focus on the surface.
At 10mm/sec, it went about 9mm though. It was enough so that when I bent the board, it easily sheared on the cut line.
But then I tried cutting out a 10mm circle. I had to go all the way to to 3mm/sec AND I had to focus in the middle of the board. Lots of charring.
Why was it so hard to go 12.7mm when it can so easily go 9.2mm? Does this mean that I need a 4 inch lens? The depth of field is greater so that helps. But the spot size doubles so that hurts. I am not sure which wins in the end.
Question two - I get flaming, and I am concerned the flame will damage the auto focus probe or the aiming laser or the nozzle. My compressor is going, but it is the standard small one, and does not blow much air. Do I want to find a way to hook up a real compressor? How can I adapt a real compressor to that snap in tubing? Should I?
