Brand new Ridgid R4512 Table Saw. Is the fence supposed to wiggle like this? It seems like it has a lot of play to me, and it is hard for me to know whether I am locking it in just right. Is anyone else's saw this way? I thought I was buying a 'nice' saw that didn't have these types of problems. I have already spent hours calibrating this thing and have everything pretty close to perfect except for this nagging fence. Blade came lined up perfectly parallel to the miter slot. Blade is a straight 90. Miter gauge is perfect.
