  • Hi,

    i just want to configure my new printer and the fan control shows up to 8 fans, but i have only the standard duet 2 wifi without an duex extension board.

    Is my configuration wrong?

    Thanks for help 🙂

    That only shows 3 fans configured.

    Where are you seeing 8 fans?

    What firmware and DWC version are you using?



  • Is visible on the Dashboard and also on the Status page under Fans
    Fan Control

    Duet Web Control 2.1.1
    Board: Duet WiFi 1.02
    Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 2.05.1 (2020-02-09b1)
    Duet WiFi Server Version: 1.23



  • @TiToMoskito said in Fan Control - Shows 8 Fans but i have only three connections:

    /Ethernet 2.05.1 (2020-02-09b1)

    As a suggestion, go back to DWC2.07 to see if that fixes your problem and report back please.
    I am aware of some issues with 2.10 and 2.11.

  • Thanks that worked for me, downgrading solves it.

    Is the display correct using DWC 2.1.4 ?
