Start by adjusting the <b>Main</b> control until the +lines of the grid are as straight as possible. Use the <b>Shift</b> controls, if +necessary, to correct for any asymmetry. Finally, if the best setting of the +<b>Main</b> control leaves a "wiggle" in the lines, use the <b>Edge</b> +control to remove it.
