Autodesk, after killing Artcam, has licensed it out the team of Artcam developers and it is now alive and released under the name Carveco. It has ALL the functionality of AC Pro (or AC Premium if you followed the Autodesk version) and for a limited time (rumored to be 60 days) the cost is only $1600.00 for full version perpetual use and 12 months direct support. (This is an introductory special)
It is compatible with Artcam files and is the same program as AC Premium 2018.
Check it out at www.carveco.com.
I've also been told that people with an Artcam license can get it for $1300.
