HELP! I could not find this in the forum, I might not be asking the right question. Just got my new Orion Motor Tech 80 W laser, been running test - started on cardboard (the problem is with all material MDF and Oak Plywood),even the Pulse does the same thing. the problem is that I get a laser cut and a mirror burn spot about 7 mm. not sure if is from my air. My machine came with its own air, mounted in the machine.
The far left is 600 - 100 speed at 70% 1 pass, next is 600-100 at 60% 1 pass and last is 600-100 for 40% 1 pass. thanks for your help
