The first thing I do is to set up two lasers to position a center line from the center of the rear stock holder to the point of the dead center at the top of the stock. Then check spacing from the stylus and the cutter. I use a 1/8” cutter & stylus and make sure it’s centered in the laser beam from one end to the other. Tiny missalignments will show up so they can be corrected..
