For normal xyz milling I’ve used the one supplied by “Fusion” for UCCNC. It is fairly generic and doesn’t have cutter comp, although the code for it is in there. I think it was Gerry that kindly enabled the cutter comp and that is available on this site somewhere. Both PP’s work fine on my mill.
I have also been trying to find a proper post processor for fusion and uccnc that has cutter wear enabled , been told to use a mach3 one but dont know what other errors that is going to cause
