@mpipes dropped me into this rabbit hole, and I am still freefalling.
This thing is so much fun.
Don’t know the wood species, the wood came from a Hickory Farms box they put your sausage and cheese in. it just happened to have been rendered into proper dimensions for laser fodder, so I pulled the staples and kept it.
I scrubbed it down with Fast Orange and toothbrush, water rinse. Cleaned really well, but raised the wood fibers on this stuff. That pumice hand cleaner is hard cutting, and the water is sucked right into it.
The ability to sculpt with a beam energy was science fiction in my lifetime. I love this thing.
