As I finish a print, I just saw that my bed temperature was 107ºC, even that I printed at 60ºC. As the nozzle heat was cooling, the bed stayed at 107ºC. I realized that it had some problem, then I tried to reconnect the bed sensor. Nothing happened. Then, reconnected the nozzle sensor, and appeared “def” on both of the Temperatures. I also checked the voltage of the nozzle sensor: 5v. But the bed sensor: 2.5v.

Anyone knows what’s the problem?
