I'm using fusion 360, so I'm not sure if it has that setting. Im pretty new with fusion. Still trying to figure it out, I'm used to using Mastercam and bobcad. I had the same problem with them as well. I just found something on the warpt9 site that says that there are some. It's with .066 version of Mach and the recommended fix is to revert back to .062 release of Mach and the latest version of ess driver. It doesn't specifically mention my issue but it is worth a try at this point.
