Hotend not heating
I had to swap the hotend of my MK3S+. Initially I got an ERR:MINTEMP error. After I moved the peg in the hotend the error message disappeared and everything seemed fine until I tried to feed filament. I checked the preheat for PLA and the bed temp went to 60 but the hotend temp remained around 135. Then I tried the wizard - same result.
RE: Hotend not heating
Maybe a faulty thermistor or thermistor connection error.

RE: Hotend not heating
I'll got through the details of the link.
Additional info:
When I switched on the printer right now the temp was 154, in other words a bit hotter than the roomtemp 😀 . Maybe this points to a certain area I should check first.
RE: Hotend not heating
Check the thermistor. Internal resistance measured with a multimeter should be approx. 100 kiloohms at room temperature.
