Fun little laser project

A fun little experiment for laser engraving non flat surfaces. As you may well know laser engraving items requires there to be a focused beam. With curved objects this can be quite hard to stay focused causing decreased cutting/engraving power. My workflow here was to wrap the bamboo in aluminum foil and use bCNC to run an autolevel sequence.

I know you can save the probe data, has anyone attempted to create an STL of probe data?
