ACTUAL KERF of the GF LASER

Depends on the material. There are many threads here on how to test and measure it.

Edit… took me a second to find it - this is the one I find most useful.

Compensating for kerf is the difference between joints that are sloppy or that fit with just the right amount of force. Even though a laser cutter removes only a fine amount of material, that slight difference in dimension between your plans and the physical material adds up. It’s worth noting that your kerf can…
