Hello 
The company i work for have a geiss 5axis machine that have a sinumerik 840 DI Powerline – equipped with a Windows NT-System and MCI-Board controller.
In the past they have used mastercam (a really old cheap version) with a postprocessor fo this machine (.pst format).
Now i have fusion 360 ultimate and i would really like to use it for this machine but the generic sinumerik postprocessor does not seem to have the traori, and the B and C axis movement limitations built in
