Now the lines on the needle plate, are they based on the needle being in the center position or left position?
More than likely it is based on the center position. I would take some sample squares and stitch 1/4 inch seams and measure to see what it is compared to what it should be. For example 3 pieces that are 2" in width. Stitch together and see if it measures 5" I always do this with my students when I teach beginning quilting, before we even stitch their first blocks.
