put your crown mold back in the framing square. Put a sheet of paper or thin cardboard underneath everything and trace the triangle left under the crown while it is sitting in the framing square. Cut out the triangle, take it over to your table saw and use it as a gauge to set your blade angle. When I do what you are doing, I just rip the pieces out of a 2 x 4. You don't want your backing actually touching the back of your crown. You need a slight gap there to make sure your crown sits tight against the wall and ceiling. One other thing, you need to stop your backing short of the inside corners where you are going to run a piece of crown all the way into the corner with a straight cut on it and the other mating piece of crown gets coped. Usually leaving 3-4" short is plenty.
