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?
Thanks for the links. Can't see any scorching, and everything I've measured seems OK. If there are LED's on the mainboard, i don't know how to light them. As of now there are no lights on the motherboard, but everything beyond that heater works..
