I have some square blocks 3x3. I need to cut a 2x2 pocket in the center but have the walls taper out instead of 90 degrees. I have X6 mill level 1 and a 3 axis miller. Is this kinda cut possible? I can have steps, and we are also hoping to keep the corners of the tapered walls as sharp as possible. Any ideas? I could possibly get a trial of level3
