Hi all,
I have built a Mendel90 everthing is fine I like to start printing. But there is one single problem that I cant get solved. In Pronterface there is shown a too high temperature in hotend and bed (about 35°C in hotend and 39°C in bed). I tried all settings in Marlin and none fits. when I heat the extruder, both temperatures rise constantly. when I rise bed temperature nothing happens. with 17°C in the room both thermistors show a resistance about 140K which seems to be ok. Wiring with no resistance. What can I do?
