I used the fusion posts about 6-8 months ago and had to pretty much re write the whole thing for it to work as it kept shutting off my spindle mid cut. The file I rewrote is now not even recognized by fusion though. The problem ended up being somewhere in the header where spindle speeds labeling were/was defined incorrectly. They have since fixed whatever was wrong and it works fine for 3 axis work. I have yet to try my hand at any indexer projects with it but am anxiously awaiting when they put out something similar to deskproto.
