Hotend accident - damaged board?
Hello,
I am repairing a MK3s after a hotend accident (wrapped in plastic, torn outlets to the thermistor and heating element). After replacing the thermistor (100k), the printer still shows 0 ° C, if I connect the new thermistor instead of the heatbed thermistor, it shows the temperature correctly.
I assume that the electronics on the board is damaged (due to a short circuit / 24V contact on the input from the thermistor).
Is this input somehow protected or will it be necessary to replace the entire control board? Alternatively, can the extruder thermistor be switched to a free position on the board and change the configuration in the firmware?
Thank you
Michal
