Vinzenz

Hi, I just assembled my new Ultimaker Original +. Today I installed Cura and tried to perform the Build plate leveling. There I get a problem: the head goes to the front left position, I calibrate the position with a piece of paper. The display of the controller tells me that the z position is 3 mm here. So far so good. But then the head goes to the front right position and changes the z position to 6 mm. Therefore I can`t adjust the level at this position because the plate is too low :-( I can`t reach the distance 0.1 mm with the spring. I hope someone can help me Kind regards, Vinzenz
