Hi. I’m new to the laser world and bought an Ortur Laser Master 2 20W. One of the main things I want to use it for is cutting through 3mm wood and smaller. I have tried for about a month with only a little success recently when I heard back from GearBest to move my medium to about 35mm from the laser. That helped a lot but I have only been able to cut through my 3mm pine plywood when doing about 25 passes. My settings are 600mm/sec, 100% power, ~33mm from the laser. I think I have found that I need to give the wood a chance to cool more before doing another round of passes. Can anyone help me understand how to do this better with my laser?
Below is a picture of some of my MANY attempts to figure this out.
