Bed leveling

As explained in the Get Started section the first layer of a print is very important. Therefore regular bed leveling is advised. Always re-level the build plate when you notice that the plastic is not equally placed on the glass plate. After transportation of your Ultimaker 2 it is also advised to re-level the build plate to ensure your 3D prints adhere well to the build plate.

To start the bed leveling procedure on your Ultimaker 2 you must activate it from the menu. Therefore, navigate to "Maintenance" > "Build plate".

Wait for the Ultimaker 2 to do its homing procedure and continue when the print head is in the center at the back of the build plate.

Setting the height

The first step is to roughly level the build plate by rotating the button at the front of your Ultimaker 2 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.

Fine-tuning

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 put pressure on the build plate while fine-tuning with the calibration card; this will lead to inaccuracies.

Successful first layer

When 3D printing, it’s very important that the first layer is nicely pressed onto the glass plate with flat lines of filament and no gaps in between. The images below demonstrate a successful first layer and two unsuccessful ones.

Successful first layer thanks to good build plate calibration
Successful first layer ✔
Unsuccessful first layer thanks to too tight calibration
Build plate too tight to nozzle ❌
Unsuccessful first layer thanks to too loose calibration
Build plate too far from nozzle ❌
