I want to start using jigs I am tired of wasting 7 inches of lumber in all carvings I made to jigs one for 11" x11" pieces the jig is 18x 11" and the other jig measures 31"x11" for 24' long pieces when I loaded the board the screen asked what the board thickness is on the card the measements are 11x11x3/4 thick do I need to change the board thickness on the settings when using a jig. Thank you for any help. Doug
