Hi
First time i tryed printing after updateing the firmware it auto leveled and started printing fine but because the print failed (lost grip on build plate) i abort it. It then lowered the build plate and unloaded my filament.
I then reloaded the filament and tryed agian. It started printing, failed agian and when i aborted the print the bed didnt lower and i got the ER18.
My UM3 now shows the ER18 (print head connection error) every time i turn on the printer or sometimes it will start up but then gives me the ER18 message agian when i try to auto level.
I have tryed resetting it to factory settings but that didnt change the firmware back as i had hoped and it still says ER18
Could this be because of the firmware update or is it just a coincident?
