I have omit a parameter in configuration ?

You have created a confusion : the K-TYPE label on PCB : positive on the left and negative on the right but in your manual you show as positive on the right !

I have added grace to debug, to show error for open circuit. //#define BOGUS_TEMPERATURE_GRACE_PERIOD 20000, If marlin fail the serial port is not open. After few hour, more debug, check wire, test another thermocouple. all is good... I close the issue
