I have some issues with my second nozzle. I installed it yesterday and all looked fine. Nozzle heats up and reads temperature correctly. Now i try to load filament into this nozzle using the load filament option: The hotend heats up and platform moves down and the printhead smack in the middle of the buildplate. Then the extruder doesnt work sadly. I have tried using repetier sending all kinds of (suggested by others in this forum) yet but to no avail.
I tried moving the extruder cable from extruder 1 to extruder 2 and this works fine. I also checked the voltage and it was all ok. Even switching around the plugin driver boards doesnt fix the issue.
