Yes, the GF can cut 1/2" maple. I did a deep engraving a logo (photos to follow)then cut out a 5.25" disc around the logo.
Wood: 1/2" maple. I picked it up at a specialty flooring lumber yard in the Bronx. They let you go through their collection of wood and pick the planks you want. The plank was 13’ long x 14.25" wide. Rosenzweig Lumber
It is not really retail but if you arrive in jeans and a flannel shirt they will let you roam around. When you first get their ask someone on the loading dock to direct you to the office. It is in the back.
Specs
Pass 1: Speed=100 Power=Full Focal Length= auto Result: .115" Deep cut
Pass 2: Speed=100 Power=Full Focal Length=.385 Result: .216" Deep cut
Pass 3: Speed=100 Power=Full Focal Length = .285 Result: Cut complete
Note: I used a depth gauge to measure the cut depth after each pass and changed the Focal Length accordingly. For new users the Focal Length tells the laser where to focus the laser beam. After the first cut the wood (wood to be vaporized) is now .115" thinner than before.
Important Note: On the last pass the wood started to char in the upper left corner. I recommend increasing the speed and making 4 or more cuts. I can sand off the charred area but it isn’t pretty.
