Good morning
This morning I woke up with a beautiful print (duration 6 hours) completed successfully, but the extruder was turned on and the temperature hotend fixed at the working temperature.
I turn off, pc, ramps and unlink Arduino, and than I restart everything but temperature was set to 0.
The thermistor marks 112k, 120k to the connector on the ramps so I try to pass it from t0 to t1 but nothing changes, always Temperature 0.00
I changed a new thermistor directly connected without wires on the ramps, I separated the ramps from Mega2560 and I reassembled, and I reloaded Marlin but still nothing.
Is it possible that ATmega2560 is broken and is no able to handle the thermistor, but only those? everything is working properly.
or is possible that RepetierHost does not shows right temperature, becouse yesterday I have seen some trouble of working in Repetier.
Thanks
