      Hey,

      I have a problem and didn't really understand where it derives from.
      I'm setting up my Tenlog Hands 2 with a Duet 3 6HC and a 3HC.

      The default hotend / extruder combination has a common trace for the hotend 24V supply and the fan's 24V power supply.

      I connected the hotend to out0 on the 3HC and the fans to out7 & out8 on the 3HC with the jumper set to V_FUSED.

      So looking on the wiring diagram they should also have common V_FUSED on the 3HC and the GND connection switched by a FET (PWM etc.)

      But the Duet alsways resets if I enable the heater while the fans are plugged in.
      If I don't plug in the fans everything works as expected....

      Can someone tell me why this is happening and how to connect this board properly to the extruder?

      Thanks

        As stated in this thread, the problem is solved after swapping the cables connected to the 3HC on the out0 / out1 headers.
