Created a taper hole in a solid with boolean operation in mastercam X4. When rough pocket or finish toolpath is created, I get a flat side on the arc all the way down (shows on backplot ,verify and part when machined). I have a Bridgeport R2E3, therefore post is set to break circle into quadrants, using radius (but I have tried I,J,K) in absolute (g90) and yes the xy is ticked. This post works great for 2D ops and will produce round circles but when taper ????. Any ideas would be helpful. Picture attached shows result displayed.
