6. Assemble Duet Controller

Making sure the board is orientated in the correct way as displayed in the image.

The Large Cable Tie highlighted in Orange is for the 4 Stepper Motor Cables and the Limit Switches.

The Small Cable Tie highlighted in Red is for the power cable.

The Small Cable Tie highlighted in Yellow is only needed if you have the Ethernet Version, and is to secure the Ethernet Cable.

Insert a M4-Cap-Head-Bolt-20mm through each hole on all 4 corners on the Duet 3D Controller.

Onto each bolt slide a 1/4"-Nylon-Spacer.

Now it is time to join the Duet to the Duet Mount. Insert the bolts into the holes on the Duet Mount and secure using 4 x M4-Nyloc-Nuts.

If you have received the Duet Wifi External Antenna version please follow this Step, if not proceed to Step 4.

Unscrew the antenna wire from the antenna arm. There will then be 4 parts, antenna wire, star washer, spring washer, hex nut, antenna arm.

Discard the hex nut as it is not needed for the assembly.

Insert the Antenna wire from the back of the Duet Mount with the spring washer. Once pushed through add the star washer and screw on the antenna arm.

Follow image 2 to route your cable through the holes on the Duet Mount.

Push the antenna fitting onto the Wifi module until it clicks into place.

Insert 4 x M5-Low-Profile-50mm bolts through the holes on the Duet-Mount indicated in red.

Place an Aluminium-Spacer-40mm Spacers over each bolt followed by a Slot-Washer and finally an M5-Drop-In-Tee-Nut.

Line the assemblage up with the X-Gantry 2040 Extrusion on the right hand side of the machine (if looking from the back) and fix into place by tightening the M5-Low-Profile-50mm bolts until the M5-Drop-In-Tee-Nuts engage

The Mains Power should remain off during all wiring of the Duet Controller.

PSU Cable from Power Supply - Connect Red Positive Wire into the Top Screw Terminal and Black into Bottom Screw Terminal.

If the wires in your kit have white printed tags, please ignore this step. Each wire, at the connector end has a coloured clip with a number. This colour and number identifies this wire. Please see key below.

(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

The connectors for the Duet controller are keyed, so there is only one way which they can plug in.

Use 8 x M3-Cap-Head-Bolt-20mms & 8 x M3-Nyloc-Nuts secure the fans highlighted in Yellow onto the Mount with the Fan label facing outward.

Thread 2 x M5-Low-Profile-60mm Bolts through the fan mount. Then slide the a Aluminium-Spacer-40mm highlighted in Blue over each bolt.

Now attach to the Main Board mount using 2 x M5-Nyloc-Nuts.

Connect the fans to 'Always On' Fan connection of your Duet Controller before tightening the M5 Nyloc Nuts.

It is important that Air is blowing towards the controller when the fans are on.

Using the already inserted cable ties fix the wires into place securely to prevent any unnecessary movement and to keep the machine looking neat!

If you have the Ethernet version also secure that.
