What am I doing wrong? a simple cutting board made up of glued up strips. after gluing I ran the length of one side along the jointer and followed that by ripping the opposite length for parallel. Than I cross-cut each of the sides using a cut-off sled and i get corners out of square. Is this my machines out of square. I checked the cut-off sled to the blade and its square. I check the fence to the blade and its square. If I get one square corner is there a correct sequence of cuts I could make to assure the other three corners are square? thanks in advance
