Free, logical and highly recommended if you want to do CNC. > **[Carbide Create CAD/CAM Software for CNC Routers](https://carbide3d.com/carbidecreate/)** > > Carbide Create is a CAD/CAM program for CNC routers. It runs on Windows and Mac OS X, it's not cloud software that can be insecure and unavailable. I designed my own clamps that are easy to use and give you a lot more room. > [@Modifying the SM1 Table and its Clamp System](https://forum.snapmaker.com/t/modifying-the-sm1-table-and-its-clamp-system/8678): > > I have now completed the bed and clamp modifications for my SM1.
