Thanks Chris. I thought he was referring to another adjustable parameter in FC. The profile paths have "use compensation" , on by default. In what context would one not want to allow for the tool size
So I could define a new tool and pretend it is 0.2mm larger in diameter and use that for roughing out, then use the correctly sized tool for the final cut.
This may provide a shortcut for adding a finishing pass to the profile paths. They have finish depth which allows finishing cut in Z but no means of finishing the profile itself, it seems. It would presumably be fairly simple to do a first pass with an inflated compensation then a finish pass with the true size. Adding a new option to define "profile finishing cut" should straight forward enough.
