ArtCAM JewelSmith 9.1 is a legacy version of a CAD/CAM software suite that was officially discontinued by Autodesk in 2018

ArtCAM JewelSmith 9.1 is a legacy version of a specialized CAD/CAM software for jewelry design that has been since July 7, 2018. While you may find "free download" links online, official support and activation for this version are no longer available from the developer. Status and Availability

A cracked version of ArtCAM 9.1 usually cannot talk to modern CNC controllers (like Mach3, PlanetCNC, or DSP controllers). The post-processors were written for parallel port (LPT) machines. Unless you are running a 20-year-old PC with a parallel port, the software will "work" visually, but it won't cut material.
