I use Fusion 360 for a lot of my CAM and I want to run the first set of roughing toolpaths a bit faster and then up the smoothing settings for my finishing pass. I have an ATC, so I want it all to be in one file.
I realized I can just add a "Manual NC" operation with "Pass Through" in front of the operations I want to have the smoothing applied to and do a G64 call to turn on my appropriate smoothing.
Here's a screen shot showing this; first three ops have one setting, and then I can change it to something else for my finishing passes.
Just sharing in case it helps someone else who wants to do this:
