Five Axis Fusion360 for newbies

Morning All - I'm designing then building a 5 axis machine (trunnion and rotary type) and I'm new to 5 axis. So interested in any heads up info on how Fusion works in this area and any general discussion about 5 axis for beginners. eg kinematic centre, Fusion posts, suggested or target speeds for trunnion and rotary. I'm figuring out speeds for these now so I can size the motors. Epochs a router but then I'll move onto a mill once I get comfortable. Epoch is a development of Frankie a 3 axis router I built and sold. Thanks for any input. Peter
