Always On fan... not on?



  • Hello all,

    I have just connected my e3d v6 fan to my duet wifi "always on" fan connector but the fan isn't kicking to life. I've disconnected and checked continuity of the wires to the fan which is good. I've tried moving from always on fan 1 to always on fan 2 (not identified as such but from closest to the main VIN to the next one along) but still the same. I have changed the fan as I had another laying around - still no good. Disconnected the fan and checked for voltage - nothing coming through, despite getting 0.02 continuity.

    I have RRF 3.1.1 - do I need to configure the always on fans so they go live (as I've read the dozuki but it only states fan0,1,2 which I presume are the PWM fans?)

    If so, how do I configure them in my config.g?

    Do you have a jumper on the V FAN selection? If you have a v1.03 or newer, check if the fan fuse is still OK.
    See https://duet3d.dozuki.com/Wiki/Duet_Wiring_Diagrams for further details



  • Didn't realise there was a fuse for the fans... and even with the diagram took a while to find it!

    Fuse it is. 👍
