There is a significant learning curve associated with both the CAD and the CAM components of Fusion 360. I was using Fusion 360 for CAD for 3D printing, so I was inspired to make the CAM work for my MPCNC. Note that you can use Fusion 360 for CAD and then take the resulting files and use Estlcam for the CAM. I frequently use Fusion 360 for creating DXF files that are then used in Lightburn for laser work.
As for Fusion 360 CAM, this tutorial is the first one I used. With significant interface changes in Fusion 360, the tutorial is dated, but there are some points in the video that really helped me. For example, the use of the cloud library for the storage of tools, and the fact that, by default, stock is created with extra height.
The Product Design Online YouTube channel is particularly beginner friendly, and he as starting some CNC videos when I last watched his content.
Winston Moy’s has a maker channel focusing on CNC machines. He uses Fusion 360 for many of his projects and outlines the CAM toolpaths and settings. I found his early projects helpful for understanding Fusion 360 CAM. In his later projects, he uses CAM in sophisticated ways that are beyond my abilities.
The NYC CNC channel has some helpful videos. They really vary in complexity and applicability to the MPCNC, but it is worth scanning some of them.
Lars Christensen channel will be really dated at this point, but he has a few CAM tutorials that I found helpful.
You will need a postprocessor for Fusion 360. The latest can be found here.
