I discovered that while changing filament, sometimes I preheat the printer for a while. And few days ago I heard that the parts cooling, even not printing, goes front 0 to maybe 20-30 then 0, then ... and then nothing. Today the printer stopped working with this error. Do you think the EBB board can be dead?
I cannot use the printer anymore since it fail with the message (see screenshot).
Thank you for your help.
