    • Berd air pump to E1 output

      I am looking at installing a 24 Berd air pump on my duet2 wifi. specs below.

      Board: Duet WiFi 1.02 or later (duetwifi102)
      Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.0 (2020-01-03b3)
      Duet WiFi Server Version: 1.23

      I have read a lot on using the spare heater output to drive the pump the question that I have is with assinging pins in version 3 firmware. I have tried the following and have had no luck. Any help would be greatly appreciated.

      M950 H2 C"nil" ; disable heater 2 and free up the associated pin
      M950 F0 C"e1heat" Q500 ; Fan 0 is connected to heater 2 pin, PWM at 500Hz
      M106 P0 S1 C"Berd"
      M563 P0 S"Part Fan" D0 H1 F0 ; define tool 0 ( heater 1 fan 0 (berd)

    • RE: 24v PWM fan at 100% only outputs 4 volts when fan connected

      Did not notice that on the 1st mosfet. Are they replaceable? I have tried to map to the 3rd PWM for my part cooler but I have not had any luck. I posted what I tried above.

    • 24v PWM fan at 100% only outputs 4 volts when fan connected

      I have my part cooling fan on fan 0. It has worked for 6+ months. yesterday I it stopped working. My hotend fan is still working. I checked voltage on the pins and it is 4 volts with the fan connected and the fan at 100%. when I disconnect the fan I get 24 volts. I have tried multiple fans all act the same. I am using 2.03 firmware. This is what I have in my config file for fans

      ; Fans
      M106 P0 S0 I0 F1 H-1
      M106 P1 S1 H1 T40

      ; Tools
      M563 P0 D0 H1 F0
      G10 P0 X0 Y0 Z0
      G10 P0 R0 S0

      I have tried to remap the part fan to fan 2 using

      ; Fans
      M106 P2 S0 I0 F1 H-1
      M106 P1 S1 H1 T40

      ; Tools
      M563 P0 D0 H1 F2
      G10 P0 X0 Y0 Z0
      G10 P0 R0 S0

      No luck . I have also looked at the board I don't see any issues with the board any ideas?
