When the plate has reached the target temperature, the nozzle is heated. This happens up to about 5-6 degrees below the target temperature, until the ender displays a "Heating Failed" error and the connection is lost. The effect is independent of the setpoint temperature. Seems like an Offset of -6 degrees.
No SD Card in the Printer, temperature intervall (autoreport) 0s
