Hi
A couple of days ago the hotend wouldn't heat up and i got a couple of errorcodes/warnings in the display. The bed heats up just fine, so i ordered a new hotend parts (heater, thermistor and a new aluminum block). Changed all of this, but still the same error. I can se that the thermistor works because it changes values in the display when touching the thermistor-end. Any good ideas why the heater doesn't heat?
When starting the preheat both the bed and the nozzle temperature starts at about 25c. There is no heating at all. The printer takes about 10-15 sec to conclude with the error message.
