Printing half the height (z axis) after upgrading to 2+

[Dirk3DMinerva 0]

hello,

I upgraded my Ultimaker 2 to 2+ this week and something went wrong..

Half of the time the machines crashes with code Error05 Z axis (Z limit switch is free and functional) and the other times the printer starts well, but prints the model in half the height.

Anybody any idea what went wrong with installing the upgrade package?

Thanks Dirk

Hi Dirk,

welcome to the forum!

Most probably you accidentally plugged the hotend fan connector to the wrong port.
