3. Depending on the type of connection you are using to print to the laser, you will need to
either unplug the Ethernet cable or USB cable from the back of the engraver where it plugs
into the controller board.
4. Unplug the 4 connectors on the controller board mainly located along the left side if you are
looking directly at it. Out of one of those 4 connectors, on the newer machines it will have a
bracket with 2 Phillips head screws holding the connector in place to secure it to the board.
If you have the newer machine, use a #1 Phillips head screw driver to remove the 2 Phillips
head screws from the bracket so you can unplug the connecter. Look at figure 2 for
reference.
