CNC (Computer Numerically Controlled) routing is a method of making things using computer aided design software (CAD) to design something and then the router machines it.
The Process:
CNC pre-made designs available free
To get started right away, you can use a website that collects pre-made CNC make files. There are thousands of options, look for .STL, SVG or DXF files.
Thingiverse (2D and 3D designs)
Pinshape
Design software programs - CAD
If you want to create your own project from scratch or modify an existing file, use any of these free programs.
Carbide Create (download the free design software for 2D designs)
Tinkercad (Free design software for 2D and 3D designs) For 3D designs to use with the Nomad CNC, Meshcam software is necessary to generate g-code.
