    Hello everyone,
    i am running an e3d v6 Hotend on my Printer, to wich i have connected a thermocouple and an external thermocouple board
    but when i turn my printer on it gives me 260 °C for the hotend temperature altough it actually is at room temperature
    Assuming that it is a problem with the thermocouple, i have removed it from the thermocouple board, but even with no thermocouple attached, the printer still reads 70°C for the hotend (which obviously is also wrong) finally when i remove the themocouple board itself, it says 99°C
    I usually would suspect faulty wiring or a firmware issue, but i haven't changed anything in the temperature settings since it last ran fine
    has anyone an idea what could be the reason for this and how to fix this?
