I was ripping some 3/4" cherry this evening, the first time I've ripped hardwood on this saw. The wood became hard to feed about halfway through, and a lot of the pieces came out with burn marks on the piece between the blade and fence. Also, the pieces were very slightly convex on the blade side (I think it was the blade side, at least).
This made me think the rip fence was out of adjustment, but to the extent I'm able to tell, it appears to be exactly parallel to the blade and to the table. I'm going to borrow a dial indicator and make damn sure it's parallel (or, more likely, angled away a couple thousandths), but in the meantime, are there other things that can cause this? The saw is a Craftsman 22122 (or something like that); it's the mid-range model of their new line (cast-iron wings but no Biesemeyer fence).
