Ok who’s working on the 5 axis ox?
http://www.5axismaker.com/ is using some other extrusion than the V-slot and C-beam, but they have something going for a while now … Would Fusion360 be able to generate the gcode for a 5 axis machine?
I sure wish we had good tools for 5 axis and not just 3+2. It is not trivial to even define what 5 axis is because you can do it several ways and the Gcode has to be made for very specific machine configurations. I have been told that the Smoothie has firmware support for it but I have not seen any video on how it’s done nor what tool chain they used other than their board. 5 axis is the holy grail for CNC so I hope this catches on and the Open Source software catches up.
Partial 4 axis can be simulated - MeshCAM is a not too expensive software, amongst others, which can help to do several faces.
True 5 Axis, like you say, can be very machine specific. It could be simulated, as seen here : https://youtu.be/LuED2IbdcOs. Just the multiple angles and tool changes properly sequenced. But I doubt anyone would want to try that approach to do the helmet in 5 axis sculpting as done here : https://youtu.be/RnIvhlKT7SY !

@Steve_Anken very nice one and surely inspiring for a light duty machine
@SuperCharger619 I’d better target at some kind of “C-Beam X5” (just to say @Mark_Carew_OpenBuild hmm ;-)) with a higher Z and combined rotating assembly (ala PocketNC, http://www.pocketnc.com/pocket-nc/) on the table… Just thinking 
@Serge_Ecoiffier machining pr0n 
Oh and that titanium crown, oh my…
