I got a new Incra for Christmas, and was very excited to add the sort of accuracy they are known for to my shop. I quickly got it close enough to square just to try it out, but hadn't used it much until last night.
I made a cut and checked it with my machinist square, showing that it was off. I went back through the instructions, and set it up again using my machinist square flush to the fence of the Incra, and flush to the body of my blade. Initially the far end of the square showed a gap of about 1/32" or so. I made another cut, and got the exact same results, if not worse!
I checked it with my machinist square and my framing square. I checked both squares against a stock edge of plywood to ensure their squareness and both appeared to be dead on. I even recheck the gauge to the blade once all the bolts on the Incra are fully tightened and it still lines up.
I kept the blade raised a lot higher and made some more cuts which made it a little better, but not much. I have a Ridgid R4512 which I've heard are notorious for going out of square at different heights, but I hadn't found that to be true on mine as of yet. I also set the blade parallel to the miter slots with a dial indicator.
What could I be missing here? Is it my square? Is it my table saw? Is it the Incra? Is it just Murphy teaching me a frustrating lesson?!?!?!?!
