Error: M106 : Fan 2 not found



  • On my Duet 3 MB6HC with Ffrmware: RepRapFirmware for Duet 3 MB6HC 3.1.1 (2020-05-19b2) I get Error: M106 : Fan 2 not found. I'm not sure where this originates from. Any config jedi that can take a quick look at my confg.g?

  • Nothing I can see there.
    Do you have anything in your config-override?



  • My config-override.g looks like this

    When do you get that error?
    What do you get if you send M98 P"config.g" ?

    Do you have anything in your tool change files?

    You don't have much defined in your config.g, can you post your other config files that may be getting called?



  • @rzi You don't have any fans defined in that config.g you posted.
    That file also looks incomplete.

    Goto https://configtool.reprapfirmware.org and set up your config.g



  • @Phaedrux It was a user error. I have two CNC machines. On my old machine I also control the dust extractor. with the M106 command autogenerated from my postprocessor. My new machine has nothing connected so it hits an error, naturally. Still, you pushed me in the the right direction by mentioning other config files, so thanx. 😃
