    When it's idle, the heater works ok, but when started printing it shows Heater fault error in a few minutes.(or sometimes in a few seconds)
    Sometimes it continues up and down about +-20 Degree C.
    I thought that the FET for heater 1 has a problem and changed the config setting to use heater 2. But the result is the same.
    Does anyone had the same problem ?

      sudden drops or spikes indicate a wiring problem. check the crimping on the cable.

      or move the cables by hand
