This is with a Freud 2+2 raised panel bit, nearly brand new. Only ran made 15 feet of board through this.
I'm taking off small passes, but I still get this light line on the board. When it gets stained, the light line turns darker than the rest of the board.
The board is white oak, and the bit ends up getting some pitch on it. I've tried this at all different router speeds (in a router table, of course) and different feed speeds. The problem only happens against the grain. It also won't sand out.
