Afeter 30 mins printing temp of bed set to 0
Afeter 30 mins printing temp of bed set to 0. In gcode i has no see it.
I enable logs of printing and it has gone now.
So it is not in gcode we send. Might be that it comes from some protection tests in firmware. If it happens frequently keep logging enabled so you can check the logs afterwards and see if there are any messages from firmware.
