Step 4: Remove all 5 connectors and the red and black power wires from the PCB.


5.  Remove the four small nuts that hold the PCB to the x-axis. These are very small, be careful they are not lost.

It can be helpful to have someone hold the hatch open during this step.


6.  As you remove the PCB board, note that there are 4 spacers on the ends of the 4 screws, once again be careful not to lose these as you remove the board.


7. Once the board is removed, put some masking tape on the screw heads on the other side of the x-axis plate. This will keep the screws from popping out as you put on the replacement board.

 

                                                                                                                                                                                             

8. Line the replacement board up with the 4 screws and spacers, and set it into place.



9. Put a single nut on the end of a small screwdriver, then line it up with the threads of the screw and attach the nut.
