Preheat Error: Nozzle temp cannot go mor than 130 degrees
Hello,
I have a Prusa I3 MK2S S/W version 3.2.3 . I preheat the Nozzle at 157 degrees, the temperature gradually rises to 130 degrees and then I get a Preheat Error.
I check Thermistor and heater are connected correctly, the fuses are good, the hotend assembly is correct, the thermistor is ok, there is 12 V on the heater.
I go from 28 degrees to 100 degrees in 3 minutes and after 7 minutes I'm at 130 degrees! at this point the setpoint goes to zero, there is no more 12 V on the heating and the nozzle cooling fan is triggered.
can you help me! Thank you for your support sincerely
