CNC Router - 3D tool stack / open-source

Hola fellow makers -

I ordered some round-tip bits, which ought to arrive soon - the idea is to experiment with some 3D! Like a topographical map, an animal (kitty!), etc.

What tool-stack do you recommend for that?

Recently I’ve been using Debian Linux /Inkscape / Kiri:Moto / Universal Gcode Sender (UGS). That’s been good for my use case of 2D shapes etched into wood - text, shapes.

A lot of people have mentioned how cool 3D maps in wood would be. Also, I’ve got a potential client who wants sort of a rectangular tray with rounded insides - which I think could be completed with a large rounded bit and/or “3D” bits.

I haven’t even looked into greyscale depth maps, and how to get them into 3D models which could be used in Kiri:Moto or other tools.

Would love to hear y’alls thoughts and ideas!

Gracias!

As a quick side note: Last week, I moved the CNC gear to my apartment buildings social room, and had a free “engrave your thing” workshop + pizza event. The idea it just show people what’s possible, and get some local clients. An issue I had was there’s no internet there - so I couldn’t use Kiri:Moto as I typically do (web browser). I believe it can be installed locally. But its a good reminder to angle towards an open-source and non-internet dependent stack. Could be a separate thead, but putting it here for musing sake, to see what you all suggest.

I think you already have your tool stack. Kiri:Moto supports depth maps. You don’t have to get them into 3d models; Kiri:Moto supports them natively, as do several other tools. (It’s easier than you think!)

Kiri:Moto has Electron builds (super handy for folks who don’t want to use development tools) and is also easy to run from a local clone of the repository for folks who are minimally comfortable. I’m a back end developer, not a front end developer, and even I have been able to do that. :rofl:

Here are the instructions for running it locally, and here are Releases · GridSpace/grid-apps · GitHub where you can download electron apps for Windows, Mac, and Linux.
