Hey Loren, welcome to the Village! Two things to look at. First, make sure the table is a perfect 90° to the blade. Don't trust the gauge. Use a small square, or a small protractor, or even the side of a credit card to check that the table is square to the blade.
Second, make sure you have proper tension on the blade. You want to hear a high "ping" when you pluck the blade. If you hear a "clunk", it's not tight enough.
So, come on in and join the fun!
