So I got put in charge of our 50W laser at work last week (which makes me even more excited for when I get my GF) and I was helping a customer make some hardwood puzzles out of a bunch of different woods. One of which was sepele (http://www.wood-database.com/sapele/) and for whatever reason we couldn’t through our 1/4" sheet of it. We tried different speeds, frequencies multiple passes and could only get about 1/8 of an inch through the board.
Thought I would ask around here and get some expert laser advice Anyone think of something that would explain why we couldn’t cut through? Are there other woods that are more laser resistant? I use a lot of purple heart, blood heart, and the like for some segmented turning projects and I was hoping to use my GF to make interlocking pieces to make glue ups easier and my patterns more intricate.
