After producing several slightly misaligned joints, I noticed blade was not parallel to the fence. The manual says to adjust the fence parallel to the base. I checked and it was parallel to the base, but the motor is skewed slightly so that the blade is NOT parallel to the base, and there appears to be no adjustment for that. You can force the joint parallel in softwood, but not if you are joining hardwood.  The problem is compounded when you join two pieces of wood, each with a 1/32" error.  You wind up with a 1/16" offset you have to sand down. Very disappointing.
