Nothing is Langmuir specific. All you need is the “Mach 3 Plasma” post processor. I would assume mastercam or SW cam would have that. That will spit out the appropriate .tap file for mach 3 to use and make cool stuff!!! lol
Good luck! FYI, in fusion preferences you can set it up to be like SW for shortcuts and mouse clicks etc… it makes the transition a lot easier!
