Everybody, thanks for all the help. After a whole lot of fiddling I got the thing to move, just to find out that it expects 3mm Filament, which is not sold at my local store. So faced with replacing the hotend and extruder I gave up and ordered a kp3s pro for less than 100€, maybe my first printer should be something that actually works.
