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?

[TiToMoskito]

Is visible on the Dashboard and also on the Status page under Fans

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 ?
