So I'm looking at hooking one of these lasers onto my 1040 cnc.

Says it can cut ply single pass 8mm was skeptical but then saw someone demo it on YT

I think at that price I will take a punt , really mostly doing some etching for my daughters Etsy wooden stuff. And a few ply coasters for a friend. Anyway I'll let you know how it goes.
