Duet3 config.g help.



  • I believe I have everything wired correctly so I think my problems must be in my config.g. So far steppers are moving correctly, heaters are heating, and thermistors are reading but I haven't been able to get my extruder fan to run or my piezo to show that it is triggering. If someone is willing to look over my config.g I would appreciate it.```

    Try removing the S1 from the M106 command.

    The probe type should be P5 in the M558and Z-0.6 in G31 seems a little large for a piezo setup. That will put the nozzle 0.6mm above the bed when Z=0.

    Here's my setup:

    M574 Z1 S2
    ;              Probe                 Probe  Dive    Travel  Probe

  • @gtj0 I tried removing the S1 modifier and the fan still doesn't show up in DWC or kick on at temp.

    My piezo is mounted unconventionally inside the spacer between my stepper and Titan Aero so it took a bit more force to trigger. That's why I had to use a larger offset. I had more luck in analog mode vs digital. It was working fine on the Duet wifi with RRF 2. Does analog mode no longer work in RRF 3? The Z probe reads in the 400s as it is but doesn't change when I tap it even though the LEDs on the Universal piezo board do trigger. If I were to try digital again I think maybe I have to use different pins on the piezo board. I don't remember.

    @rkrammes said in Duet3 config.g help.:

    M558 C"io8.in" P1 I1 R1 A5 F333 T5000 ; Set Z probe type to analog, active low, maximum attempts, pause, plunge speed, and movement speed

    Pin io8.in is not capable of analog input. See https://duet3d.dozuki.com/Wiki/Duet_3_Mainboard_6HC_Hardware_Overview#Section_IO. Change the M558 mode to P5 to use digital input, or select an analog-capable pin.

    M106 P0 S1 H1 T45 C"Extruder" ; Set fan 1 value, PWM signal inversion and frequency. Thermostatic control is turned on

    That line refers to sensor 1, which hasn't been configured yet. Try moving it to be later than the M308 S1 line.



  • @dc42 Thanks so much, David. I will give those a try tonight.



  • Yes! Everything is working except the fan doesn't show up in DWC. Still working correctly though. Now I gotta add a couple more fans, clean up my wiring and this config. Thanks, guys!


  • administrators

    Thermostatically-controlled fans don't show up in DWC because they are controlled automatically.



  • @dc42 said in Duet3 config.g help.:

    Thermostatically-controlled fans don't show up in DWC because they are controlled automatically.

    Would it be possible to have them show up in some way to display their speed and indicate they are thermostatically controlled?


  • administrators

    @Phaedrux You could use a 4-pin PWM fan and use the tacho output to display the fan RPM on demand.



  • @chrishamm Not many folks have 4-wire fans on their hot ends. 🙂
