When I first connected my 24v fan, to my 24v Duet 0.6, using the connectors in
this image I got a melted wires and smoke, so I searched around for an alternative, and ended up plugging my fan into the FAN0 header, only to find out that this is for the part cooling fan.
I've checked the 2 pins with a multimeter and it reports 1. Not 1v. Not 24v, as it should, but 1, on the left of the display. What's going on?
