So I’m having trouble cutting 1/4” plywood, birch to be exact. I’m having to run it at 5mm/s at 100% at 2 passes to get it to cut. Some of the pieces didn’t cut all the way through either. Any suggestions? I know the mirrors are clean and aligned because that was just completed. I have a 50w black and blue co2 laser.
Are you setting Min Power the same as Max Power? At low speeds, you need to.
I am, I just adjusted the focal point and did another test at 2mm/s at 80% with 1 pass and it worked.
