Calibration

First use

When you turn on the Ultimaker 2+ for the first time, the display shows “Welcome”. The Ultimaker 2+ will guide you through some steps for calibrating the build plate. Follow the instructions shown in the display. The Ultimaker 2+ will do the “homing” first. This means that it will move the build plate towards the bottom and the print head to the left back corner, in order to set the origin point. After this, you can start the bed leveling.

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

Bed leveling

For printing it is very important that the first layer is nicely squished into the glass plate and sticks well. If the distance between the nozzle and build plate is too big, your print will not 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. To get the correct distance between the build plate and the nozzle, you need to level the build plate. You must do that before using the Ulitmaker 2+ for the first time and then periodically.

Setting the height

Roughly set the height of the build plate by rotating the button at the front until there is approximately 1 mm distance between the nozzle and the 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

Adjust the front left and front right build plate screw to roughly level the build plate at the front side. Again, there should be a distance of approximately 1 mm between the nozzle and build plate. Turn the build plate screws to the left to move the build plate closer to the nozzle.

Fine-tuning

The last step will be fine-tuning of the build plate with the calibration card. Place the calibration card 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.

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. Check out the below images to see a successful first layer and two unsuccessful ones.
