For printers with multiple tools you can use the Tools Tab to define the heater and extruder used for the tool. In the case of the Ender 3 there is only a single tool.

Check select First tool on start-up

Enter a name for the default tool if you like. This name will show up in the Duet Web Control. In this case we used the generic "HotEnd" just to differentiate it from the heat bed.

Make sure the extruder0 and heater0 are selected and choose fan0 to set the correct part cooler fan.
