I've always signed the back of boards by letting the machine measure the board by placing on end. My question is can and how do I carve that logo signature on the back of a board without the machine measuring the whole board? some of these name boards are 8 foot long and logo is only 12 inches so i'd like to put the board in and jog to where I want it carved without the time it takes to measure the whole board. Thanks in advance.
