Reading this thread reminded me of an article that I wrote some years ago and was published in MEW issue 311, page 17 et seq in which I gave a brief review of a Shapeoko router machine which was part of a prize in a competition run by Alibre. The other part of the prize was free copy of MeshCam..
I quote from that article:
“An email exchange with the suppliers of Alibre suggested that if I was intending to use the router on aluminium (which I was, primarily) then I was going to need software to produce the G-code which was more “robust” (their words) than their in-house offering MeshCam.”
I subsequently set up Fusion 360 to provide the G-code, using it successfully on a number of projects until the machine sold.
Basically, I’m seconding Jason’s recommendation , above.
