nozzle reads 0/0

hotbed reads 17/0

err: Mintemp.

What should I do?

Hotbed Ed heats up when I place hand on, showing it reads temperature. Nozzle does not. Any advice?

I had this before, check both ends of your thermister wiring from the hot end, something loose somewhere.

I also had it once when I used to have an ultimaker in the garage, but that was because the temperature was below 10 degrees, had to heat the sensors up with a candle and a cup of hot water to get it going lol! Real high tech stuff!
