I’ve never done any metal on my MPCNC. Just soft wood, cutting boards (cheap source of plastic), and foam for practice/tests (wouldn’t want the z axis diving deep or 1 feed rate to be too fast).
I know about as much as I need to know for the CAM side of things in inventor hsm (same cam as fusion) but I need to learn more about feeds and speeds as well.
I’ve never installed any autodesk products on a business/school computer so I don’t know what it needs access too that it isn’t getting. Best bet is to try it at home or google what your problem is.
