So, galvo lasers are crazy fast, but the work area is small. Gantry lasers give you big work areas, but they are slow.
Why hasn't anyone ever put a galvo laser on a gantry. You'd get the speed of a galvo, and the larger work area of a gantry.
I found one company that does it, but they are a Chinese laser company with a super sketchy website. I did, however, find this video. https://www.youtube.com/watch?v=nWleLIfKrbg
