      Hi,

      I'm setting up a new printer and the first with firmware 3.3.0.

      When tuning the bed heater it got to "phase 4" and the message mentioned "tuning with fan off".

      Simple question: Fan? What fan?

      Thanks.

      Frederick

      Printers: a small Utilmaker style, a small CoreXY and a E3D MS/TC setup. Various hotends. Using Duet 3 hardware running 3.4.6

        Spurius message for bed heaters. With hotend heaters tuned as a tool it will turn the part cooling fan on and off to take its cooling effect on the nozzle into account.
