Ok, I found the bug. I don´t know why that is so, but never mind. I changed the wire orientation of the thermistor and that was it. Is there any diode in the thermistor or why the orientation matters? I thought that a thermistor is a restistor with a almost linear restistance dependency to the temperature.

Hi Ian,

I have a Kossel XL with only one extruder. I am using the dc42Kossel config:

Hi,

I´m a beginner with 3D Printers. And now I have a serious problem with my Duet 0.8.5. When I want to switch on the hotend with pronterface, nothing is gonna happen. The LED which should light up also doesn´t show any reaction. The heat element (incl. wires) and the thermistor is working fine. I checked both of the hot end plugs and none of them is showing a voltage output.

Cheers
Nico
