(0)(Black) X-Axis Limit Switch
(1)(Brown) Y-Axis Limit Switch
(2)(Red) Z-Axis Limit Switch
(3)(Orange) X-Axis Stepper Motor Wire.
(4)(Yellow) Left Y-Axis Stepper Motor Wire.
(5)(Green) Right Y-Axis Stepper Motor Wire.
(6)(Light Blue) Z-Axis Stepper Motor Wire.

Step 2 X-Axis Fixed End Mounting

Attach a Drag-Chain-Fixed-End to the V-Slot-2040-750mm using an M5-Low-Profile 8mm and an M5-Drop-In-Tee-Nut.
It should be located 150mm from right hand end of the V-Slot-2040-750mm if looking from the back. Ensure that it is parallel with the V-Slot-2040-750mm.

Step 3 X-Axis Moving End Assembly

WorkBee Kits may include different version drag chains, please refer to the correct drawings for assembly of the version supplied.

Attach a Drag-Chain-Moving-End to the X-Drag-Chain-Moving-End-Mount in the orientation shown above using 3 x M5-Low-Profile-15mm bolts and 3 x M5-Nyloc-Nuts.
Attach a Drag-Chain-Moving-End to the X-Drag-Chain-Moving-End-Mount in the orientation shown above using 2 x M5-Low-Profile-15mm bolts and 2 x M5-Nyloc-Nuts.

Step 4 X-Axis Moving End Mounting

--- WorkBee 2.2.1 ---
Secure the X-Axis-Moving-End-Assembly to the X-Plate-Back using 2 x M5-Low-Profile-60mm bolts and 2 x M5-Nyloc-Nuts.
--- WorkBee 2.2 ---
Secure the X-Axis-Moving-End-Assembly to the X-Plate-Back using 2 x M5-Low-Profile-55mm bolts and 2 x M5-Nyloc-Nuts.

Step 5 X-Drag-Chain

Like with the Y-Axis, lay the X-Drag-Chain flat on a table. Feed through the (6)(Light Blue) Z-Axis Stepper Motor Wire.

The tabs of the Drag-Chain can be flipped open with a small flathead screwdriver. Doing this will help to feed the cables.
The end of the stepper motor wires with the black connectors should be at the male end of the X-Drag-Chain (opposite to Y-Axis).
Attach the female end of the X-Drag-Chain to the Drag-Chain-Fixed-End on the V Slot-2040-750mm. It will take some force to click it into the Drag-Chain-Fixed-End. A small flathead screwdriver can be used to help pry the Drag-Chain in place.
Bring the male end of the X-Drag-Chain up to the X-Axis-Moving-End-Assembly and attach it to the Drag-Chain-Moving-End. It will take some force to click it into the Drag-Chain-Moving-End. A small flathead screwdriver can be used to help pry the Drag-Chain in place.

If you’ve followed the steps accurately your router would have been installed. So you can route the power cable at the same time.

I found that connecting the drag chains to the moving-end and fixed-end assemblies quite difficult when they were in place and was concerned that I might break them.

It was far easier to connect them first and then attach the assemblies to the frames.
