      I have a DICE Printer.
      my FAN Config
      M950 F0 C"out3" Q500
      M950 F1 C"out5" Q500
      M950 F2 C"out6" Q500

      out5 and out6 also work.
      But out3 burns my fans (Sunon MC30060V2-00U-A99).
      Measured at the fan 5V arrive.

      But the fan is already on strike at 50%.
      Can someone help me?

      Here the wirring

        Are you saying that out5 and out6 are working correctly?

        But out3 burns my fans (Sunon MC30060V2-00U-A99).

        What do you mean by "burns"?

        Measured at the fan 5V arrive.

        Are you saying you have measured that the outputs are providing 5 volts?

        But the fan is already on strike at 50%.

        What does that mean?

          Thank you for your Answer.

          yes working correctly

          What do you mean by "burns"?

          The fan rotate, then stops and smokes and that already at 50%

          Are you saying you have measured that the outputs are providing 5 volts?

          yes corretly

            Not all fans can be controlled with PWM to vary the speed.

            Perhaps the one that is smoking is one of those that cannot be controlled.

            If it is still working try 100% - that feeds un-pulsed power to the fan just as if was receiving power from a 5 volt DC source.

              Thanks for the tip

              I tried that but it did not work.
              The fan spins for about 5 seconds and then it stops.

              And I noticed now that as soon as the fan stops the board reboot. no smoke appears.
              Isn't there a possibility to use the out3 withouth PWM?

                Perhaps you are drawing more current than the on-board power 5 volt power supply can provide?

                It's limited to about 700ma according to the docs.

                That would explain why the board re-boots.

                  The fan which makes troubles has only 0.072mA - in my opinion that shouldn‘t be the reason for re-booting
                  What do ya think?

                    If you don't need PWM control or switching, can you connect it directly to a 5v source and run it as always on?

                    Is this the fan?

                      @Phaedrux yes its this type of fan.

                      I will do a test run tomorrow and will let you know!

                        Does the fan work on the other ports without issue?

                          @fcwilt @Phaedrux Thank you very much for the help.

                          I have measured the power current of the fan and found that it is too much. The current of the fan rised above 1A after a short time.

                          I have replaced the fan and now everything works.

                            So it turned out to be the fan that was causing the reset as we suspected.

                            Glad to hear you got it all sorted.
