12. Connect the replacement harness to the connector socket on the main PCB at connector location
“X/Y Home”. This harness is assembled backwards to the other harnesses in that the extra slack is
at the sensor end, instead of in the base assembly.
13. Run the harness around the left perimeter of the base interior and out the left access hole.
Replace a twist-lock cable tie to bundle all the harnesses together in front of the access hole.
14. Follow the adjacent harnesses running up to the z-motor and tie the x/y home harness to the ad-
jacent harnesses in 3-4 inch intervals up to where it runs under the z-motor.
15. Run the harness at and neat down the channel in the y home ag and connect the harness to
the y home ag. If there is a twist, correct it all the way to the z-motor so that no twist of the har-
ness is in the length from the z-motor area to the PCB.
16. Replace the EMI cover carefully by following steps 8-10 in reverse order.
17. Reinstall the remaining covers in the reverse order that you removed them and tighten the screws
to the torque specications.
18. Turn the machine ON.
19. If there is any problem with the harness, you will have received an error as soon as the machine
initialized because it won’t nd home. No further testing is required.
