Cool CNC engraver using Solar

Nice build, the author has 2 issues, 1 it takes a long time to engrave, 2 once done you need to close off the lense so you don’t keep burning. Since lasers are some of the most expensive bit for an engraver, it does make sense to do this. What would have really topped this off is if the entire thing ran on solar.
