There is a fairly steep learning curve with Fusion 360. I was already using F360 for my 3D printing, so it was a natural transition for me when I built my MPCNC. A lot of people are happy with, and do amazing things with, Estlcam. As for F360 CAM, the only thing MPCNC specific about it is the post processor. You can find a link to download it in this topic.
If you are looking for F360 CAM tutorials, I don’t know of a current author making beginning tutorials. I can point you towards some YouTube channels where I picked up my CAM (directly and indirectly), but their content might be a bit dated. The concepts still apply, but the F360 interface continues to change/evolve.
