Fabex CNC (formerly BlenderCAM)

Fabex CNC, formerly BlenderCAM, turns Blender into a CAM environment for milling. It creates many toolpath types, including profile, pocket, drill, parallel, spiral and medial axis, from 3D models or black-and-white images, with cutters such as ball-nose, V-carve and flat end mills. It offers bridges for holding cut-out parts, layered milling, chipload-based speed adjustment, operation and chain simulation, and G-code export. It suits reliefs, moulds and organic parts on small CNC machines. Limitation: you need to know Blender, and 4- and 5-axis milling is only possible through manual indexing.
