Missing pin or not ?

Postby lami3d » Fri Jun 18, 2021 3:54 pm

Hi everyone,

i have a question about a pin on the printhead that is not on my N2+ (2016) and that is on my N2 (2018).
It is the center pin on the left column on t he picture below

It doesn't seem broken? i just noticed that and wanted to know if it's normal or not ?

Thanks for your help.

No, that is an intentionally missing pin to form a KEY so that the mating ribbon cable connector that ALSO has a pin jammed into the matching hole cannot be plugged in backwards.
