Incorrect orientation of the ribbon cables.

Re: LCD not powering Up?

yea, it's the usual prusa-ribbon-cable trap.

💡
the kit should be shipped with a written warning note:
"beware of the orientation of the ribbon cables (check them twice with the pictures at the assembly manual), because we as prusa decided to reverse the common cable orientation, so that the red wire indicates pin#10 (instead of #1, as the rest of the world does)... because we are different".

dem inscheniör is' nix zu schwör...

Re: LCD not powering Up?

The online guide has had a warning for as long as I can remember. I don't have a current printed manual to look at.
