CAD (Computer Aided Design)
We suggest using Onshape to create 3D models and 2D profiles. It can be used for free, it's easy to learn and requires no installation because it's cloud based.
CAM (Computer Aided Manufacturing)
Use Cambam to specify how you want to cut your project on the Dmattic. It's powerful cam software that can be used for free or can be purchased to get unlimited machine operations.
Tutorials for using Onshape and Cambam will be available soon.
