Fusion 360 has both CAD and CAM built-in. And there is a MPCNC postprocessor for Fusion. See this topic. The learning curve for Fusion 360 CAM is significantly steeper than for EstlCAM, but Fusion’s CAM has a lot of abilities and features not available in EstlCAM.
Personally, I do all my router work in Fusion 360. I do export DXF files for use in Lightburn for laser cutting and engraving.
Then what if I want to import a bitmap picture, is that in Fusion or Eslecam?
What do you want to do with a bitmap picture? EstlCAM has some image support. Fusion 360 does not. In Fusion, you can only use images as reference.
