Hello,
I just downloaded the Create software intending to use it for CAM, it opens but does not click any of the buttons. On first opening it the screen was cropped 10% eliminating a portion of the green banner. After re-start I still don’t have it working.
The machine is a 2017 Windows 10, I 5 processor.
No, it is not for use with STEP etc. It’s essentially a 2.5d drawing program and can output CAM for that. It can import DXF (I think) and SVG line drawings.
There are a bunch of options for CAM off of models, but it generally means either a tool like Meshcam (from the same guy that does CC), or a CAD system (like Fusion360, which is free for hobbyists, and education). There are a bunch of other examples of tools listed over on the wiki.
