1 - You need to enter Fusion360 CAM-module (called Manufacturing) and set up the toolpath etc there, then export the gcode which you then can import into Easel.
Easel can not open a Fusion360 design file (CAD-file) but it will read/accept the Fusion360 generated gcode. It will not be editable in Easel.
You’ll need the appropriate Easel Post Processor installed into Fusion, you’ll find the PP download under Easel -> Help -> Download
Easel creates the toolpaths for you, but in Fusion you need to specify them. Try with the 3d carving options where @HaldorLonningdal is commenting (manufacturing). There is a lot of settings, but most of them are self explanatory. Keep in mind:
- Create your toolholder / bit, size, length, default speeds
- You may want to add a small extra to the bottom of the stock, if you are used to over cut in easel to prevent not going all thru the material
- Find how to limit the depth of cut, this is in the cut settings itself, not as global settings
- Experiment with ramp, lead in and outs
At the end, you export something called NC Program, which is what you import as gcode to Easel.
