Seriously. You’ve been disclaimed.
I hereby wash my hands of this idea.
OK, so I know there are probably 100 reasons this won’t work or is perhaps dangerous, but I wonder what would happen if you took thick wood and preheated it to something closer to ignition temperature prior to lasering?
Yes, air assist/exhaust would cool it. Yes the effect would decrease over time as the heat escaped the piece. Yes the GF doesn’t like heat, so putting something hot in it might cause an overheat message.
Still, I wonder if you could blast through 1/2" material if you gave it a boost like that. Anyone crazy enough to have tried it?
