Hello! We are myCNC, a multi-platform CNC Software which features a features a simultaneous 6-axes motion control and which can be used for a variety of uses including mills, lathes, routers, tangential knife setups, as well as plasma, oxy-fuel, and laser cutting machines. These controllers are a great resource for people who desire more granular control over their machining/cutting process, but unfortunately there doesn't seem to exist a post for them in Fusion. Currently some of our customers have expressed a need for a 3/4 axes milling post processor, however post processors for other setups (such as turning) would be amazing as well.
We have an active community that would be interested in using such a Fusion 360 post processor for myCNC, and would love to test it. Let us know if that would be possible, and thank you for your time!
