I have noticed recently that my zero clearance throat plate hasn't been sitting flat. I have check for debris, cleaned it well and adjusted the set screws. As soon as I get one adjusted flat to the top, the other one is funky and not flush. And when i slide my fence over it grabs at the edge. I noticed this recently as I was having a hard time getting it to go in. The plate for dado's fits just fine. Its almost like it is warped. Any suggestions from you SawStop owners. 52" PCS
