Verify that the endstops and steppers are still operating properly by repeating Steps 59, 60 and optionally Step 61 before proceeding. It will be much more fun this time since you have the arms and effector/hot end installed! Everything check out OK? If so, continue this step.

Open a web browser and load the DWC. Notice the temperature displays for the Heater 1 (hot end) and Bed temperatures highlighted in the first screen capture. These should display reasonable room temperature values but might be off by 5°C or so. It's ok if the temperatures are off by a few degrees and also if they are not identical.

Remove the blue silicone sock from the hot end. Enter 60° in the Heater 1 Active field and press ENTER. The hot end should start to heat up and stabilize at 60°C as shown in the second screen capture. Verify that the hot end fan turns on at 50°C, it is thermostatically controlled and turns on above 50°C and off below.

Once the hot end is up to temperature, enter 60° in the Bed Active field and press ENTER. Again, watch the temperature display to verify the bed reaches 60°C. This will take several minutes.

Next enter 225° in the Heater 1 Active field and press ENTER. Allow the hot end to reach 225°C. The third screen capture shows the hot end and bed at the target temperatures.

Now enter 250° in the Heater 1 Active field to perform the final nozzle tightening. The current Duet firmware has a maximum default hot end temperatures of 262°C but E3D specifies 285° for tightening the nozzle. Not to worry, tightening the nozzle at 250° is adequate and safer. Read about the procedure here: Final Tighenting.

You do not need to perform the PID tuning described on the E3D V6 page. You can also do the final tightening with the hot end installed on your printer if you are careful, but do be careful, 250°C can leave a nasty burn.
