Well @neilferreri did develop a post processor for Vectric products that supports everything the Shapeoko can do, it’s available here:
I believe that at least at some point Vectric pointed their customers to it when they requested a Shapeoko-compatible PP.
I’m using it as I write (working on a project using Vectric VCarve right now), with a BitSetter and VFD/spindle and it works perfectly
