      Hey guys.

      I've got a problem with my fans. Everything works except for fans 0 and 1, leading me to believe it could be a problem with the mosfet drivers.

      Anyone have troubleshooting ideas or know what kind of mosfets they are and where they are located on the board to be replaced?

      Thanks a ton!

      Ethan

        How are the fans connected?
        Do the fans work if connected to the always on port?
        How are your fans configured in config.g?
        Have you checked the fan fuse if it's present?

          presumably you mean the mosfet, as the fan mosfets don't have drivers, not the drivers - the latter would more likely than no cause 0, 1 and 2 to fail. details on part numbers and locations were recently discussed in this thread https://forum.duet3d.com/topic/15152/no-voltage-when-plugging-in-part-cooling-fan-did-i-break-it/5?_=1585522802818
