Hello, I'm coming up to you about an issue I have with a UM3E that I tried to use after few months of inactivity.
I installed the last firmware normally via the printer but, when I wanted to start a print, the UM3E failed during auto levelling step.
Actually, the build plate stops at 10 centimeters from printheads, even if I try to level it manually.
