[STL -> CNC] technique or software?

[DrQt]

Any software or techniques for generating CNC carving depth maps from a mesh or stl?

It’s not possible within Luban, correct?

You can use the STL directly either in Luban (not recommended) or in Fusion360. However, if you particularly need a depth heatmap you can use stl2png.

Edit: I do have a guide for doing 3d engraves with fusion360.

Fusion 360 Guide For Multi-Pass 3D Engrave

In a bit of a follow up to my Laser Guide and Rotary CNC Guide, I’ve decided to do a quick 3d relief guide for the snapmaker using Fusion 360. This guide assumes you know some basics of running the CNC, such as being able to jog the machine with the control app, set work origin, and set origins for the axes independently. There will also be some optional G-code changes and sizing done in other programs to achieve a better result. Disclaimer: I am in no way responsible for any possible damage to…
