My DCS575 has the alignment problem. The blade is not parallel to the long edges of the base plate.
I tried loosening the screws on the base and punching the plate to alignment but there is not enough movement. I am about to slightly enlarge the screw holes through the base to see if I can move it enough to run parallel.
it is a good saw otherwise but I hate when I run it against a square to make accurate 90degree cuts and it is out a lot.
