Insert 2 M3x20mm screws into the 2 holes in the homing Switch
Attach the 1000mm wire to the Homing Switch. Black goes to the blade connector on the long side, Red to the short side on the connector closest to the black wirw

Z-Homing Switch Installed

On the Z Router Assembly go back to the Z Homing bracket that was installed earlier
Install 2 M5 washers onto the M5x40mm screw
Insert the screw+washers into the Z Homing bracket
On the other side of the bracket place an M5 Lock Washer on the screw and an M5 Hex Nut
Slide the screw to about the middle of the slot in the bracket and tighten the Nut
Attach the remaining wire to the Homing Switch. Black goes to the blade connector on the long side, Red to the short side on the connector closest to the black wirw
On the other side of the Z Router Assembly you will position the homing switch so the blade extends off of the side of the Router plate
Take 2 M3x20mm machine screws and pass them through the front of the router plate and through the holes on the homing switch
Secure the homing switch with 2 M3 Nylock nuts using a hex key and needle nose pliers or a 5.5mm socket
Rotate the Coupler to lift the Z-plate and wait for it to Click the Z Homing Switch
Ensure that the click occurs just before the Z-Plate hits the Coupler to ensure you get maximum Z-axis travel
