Calibration for the Ultimaker 2 Extended

Bed leveling

After the “Welcome” screen, the Ultimaker 2 Extended will guide you through some steps for calibrating the build plate. For printing it is very important that the first layer is nicely squished into the glass plate and sticks well to it. If the distance between the nozzle and build plate is too big, your print won’t stick properly to the glass plate. On the other hand, if the nozzle is too close to the build plate it can prevent the filament from extruding from the nozzle.

Before the bed leveling can be done, the Ultimaker 2 Extended will first do the "homing". This means that it will move the print head to the left back corner and the build plate towards the bottom, in order to set the origin point. After this, you can follow the next steps for leveling the build plate.

Note: If you don’t see the configuration wizard, navigate to Maintenance > Advanced and confirm for a Factory reset.

Setting the height

The first step is to roughly level the build plate by rotating the button at the front of your Ultimaker 2 Extended until there is approximately 1 mm distance between the nozzle and build plate. The measurement here is not critical, just make sure that the nozzle is close to the build plate without touching it.

Rough leveling

Next, a rough adjustment will be done on the front left and right side by turning the build plate screws. Turning the build plate screws to the left means that the build plate will get closer to the nozzle. Again there should be a distance of approximately 1 mm between the nozzle and build plate.


The last step will be fine-tuning of the build plate with the calibration card. Place the calibration card in between the nozzle and build plate on all 3 points and adjust the build plate screws until you feel slight friction when moving the card.

Note: Don’t push on the build plate while fine-tuning with the calibration card; this will lead to inaccuracies.
