      I have connected the fan and set the parameter Q1000. If I set the speed in the DWC to 95%, the motor burns out!

        Can you give more detail about what exactly you are connecting?

            @Zseven I assume this is a CPAP/vacuum blower control PCB and not a standard fan, is that correct?

                @Zseven then you need to give us more details. Type of blower, how everything is wired between the PCB and the Blower and the control board, etc.

                I highly doubt the Duet board can burn out the big blower because those fan ports are limited to 1A; I assume the blowers pull more than that.

                  Hello ,
                  I have requested the data sheet from the manufacturer.

                    ello ,
                    I have now got a replacement as the last fan has burnt out.

                    08-06-2024_08-37-38.jpg

                    DC7-24V brushless turbo fan motor 100000 rpm high speed aluminium alloy impeller with brushless motor and speed controller

                    I have now connected the fan direnkt to the 24V power supply and I can control it very well with the potentiometer

                    I have now measured the voltage at the potentiometer and between the red and black cable are 5V

                    The yellow cable should be the PWM signal.

                    How can I now control this fan with the Duet 6xd?

                    Witch pins ?

                      The wiring on the photo does not match the wiring on the PCB graphics.

                      If you could provide a link to the listing and/or a full spec sheet that would help. "PWM control" can mean different things, in this case it could be 0-5V for example which would require extra circuitry.
