I have a “startup” license for Fusion 360. It is free but must be reapplied for yearly. I think that reapplying is really just click on accepting terms. The student license version is the same except I think you only need to reapply every 3 or 4 years. I thought that Fusion 360 contains a full version of HSM CAM but maybe that’s not the case. From http://cam.autodesk.com/fusion360/ “The CAM capabilities of Fusion 360 share the same proven CAM kernel as HSMWorks and Inventor HSM™”. Anyways, the CAM functionality in Fusion 360 seems pretty complete and in many ways more than I need or can manage.
