Two week ago I had to reinstall everything on my pc and choose version 43242. After that I was not able to run some of my toolpath after reposting them (my 1F was making a very loud grounding nose and loose reference)… The old fusion360 did not have circular interpolation disable.
We noticed that after I re-enable it there was no problem anymore. I informed Onefinity support and they post this… Fusion 360 and Circles (arcs) (circular interpolation)
