Has anyone had luck with this? I have tried a few post processors and experimented with tolerances. Almost all arc show a radius error.

I have not tried turning posted from Fusion. I did modify the LinuxCNC post to my own milling variant for Dynomotion. I could share that if someone needs it. My next task is figure out how to add 4th and 5th axes to that post.

HI bill,

   I had a similar problem when I started using kmotion cnc on a lathe, but it was not with fusion 360. I have another cam system, and if the kmotion cnc was set to display diameter mode on the X axis, the machine would choke on the arcs that came out of the cam system because they were being output in radius mode.

  On my cam system it would not change the arc output even if I changed the cam system setup to diameter mode for some reason. This cam system is old and no longer supported, so I just run Kmotion cnc in radius mode, and no longer have any problems.

  Hope this helps.

That fixed it. I'm using the Mach3 post in fusion and doing a search on circle leads to a scaling parameter that's by default diameter. Set it down to one for radius and it works. Still all kinds of things like tool selection, g95,96 in that post that are wrong but at least they are things I can delete manually until I get it optimized
