What's the best strategy ?

It looks okay but as usual the basic version just lacks the features required and when you start adding the modules you might as well have gone for the top version.
I think I'm going to have to run two lots of G-code, one from a 3D CAM such as DeskProto and one from a 2D Cam such as Vectric Cut2D.
As Gerry says if the origins match then all should be well.

I've just had a look and it's got most of the basic features you need for both 2D and 3D so what is it you plan on doing that this £99 software can not do.? What you think you need may not actually be the case and you could be paying for features you'll never use.!!

That said.!! . . Regards the separate G-code then it's not difficult using cut and Paste to combine into one file. Just keep a Standard template file with your Header setup then cut and paste. I do this often when I'm setting up and using Fixture Offsets(G55, 56 etc) and want to combine individual parts saved in seperate G-code files into one file.
