After replacing the service screen of my UM2 extended, Cura does not connect any more with my computer (Windows 10)
I use cura 4.5
I get the message ER05
I set the settings back to the fabric settings.
But still I get the ER05 message.
I checked all the cableconnections and the Z switch works properly.
So I tried to upload the firmware, but Cura says that there is no USB connection.
I tried another cable and computer, but still no result.
Please help me
