Meshcam generates code for the 4th axis, the point is it will not generate code so that all 4 axis can be moving at the same time. Or is this not what you are saying?
Yes..Meshcam generate Gcode for 4th axis..but it is not true 4th axis..You are canabilizing one axis into Rotary motion...
The Gcode for true 4th axis is
g1 x-.655 y.165 z-.060 a15 f5.0
whereas Artcam,Meshcam and Deskproto will generate like
g1 x-.655 y.165 a15 f5.0The main reason for my question is so I can be a bit ahead with my planning. I have a possible requirement to reproduce small complex casting by milling from solid. As it stands at the moment it would seem Meshcam can cope with this but will I need a more sophisticated Cam package in the future, perhaps for speed or smother finished.
I will probably look at bit closer at 'DeskProto Full'
Depends on the accuracy you needed... Some software only work with STL models and those STL models are not accurate representation of 3D models... Deskproto or VisualMill will work for you... The VisualMill will be much better as it has Feature machining capabilities..As I am new to Gcode programming what would a simple piece of Gcode look like that would have all 4 axis moving together in a non linear way; for that matter I don’t think I could do it in 3 axis.

See my simple 4th axis..its not a true 4th axis , i generate Gcode with Artcam
