| + | [title] Jumpers |
|---|---|
| + | [* black] Make sure your jumpers are set correctly. |
| + | [* red] V_FAN: This is where you select the voltage for the 5 fan ports. You want the jumper on VIN (pins 2 & 3) to set the fans to run on the voltage that is supplied to the Duet 2 WiFi(24v). If you set it to 5v(pins 1 & 2) the fans won't turn on. |
| + | [* black] 5v Selection: You need to select if 5v is provided by the onboard regulator(24v to 5v) or from an external 5v source. |
| + | [* icon_caution] Only use INT 5V EN or EXT 5V EN. |
| + | [* orange] INT 5V EN: Most builds you will have the jumper placed here. |
| + | [* yellow] EXT 5V EN: Place a jumper here if you want to use an external PSU to provide 5v to the board. |
| + | [* icon_note] If desired you need to connect the external 5v source to the +5V and GND pins on EXT 5V header |
