1. Display and Control
The display on the front of the Ultimaker2+ shows all important information. You just need to rotate the knob on the right to select the desired item, then press the knob to enter or execute the item.
After turning on the Ultimaker2+, the small screen will first display the Ultimaker logo before entering the main menu, which has three options: Print, Material, and Maintenance.

Pressing the "Print" option will access the SD card, allowing you to select files for printing.
Material
Press the Material option, and you can choose to change the filament (Change) or view the current material settings (Settings). Selecting "Change" will guide you through the filament change steps on the display. Choosing "Settings" allows you to further select the material type or press "Customize" to modify the material's print parameters.
Maintenance
Press the Maintenance option, and you can choose "Build plate" or "Advanced". Selecting "Build plate" allows for print bed leveling. "Advanced" contains various options for manually performing specific operations or adjusting machine parameters.
The "Advanced" menu includes:
- LED settings: Adjust the brightness of the LED lights inside the Ultimaker 2+.
- Heatup nozzle: Manually set the nozzle temperature to heat up the nozzle.
- Heatup buildplate: Manually set the heated bed temperature.
- Home head: Move the print head to the back left inside the Ultimaker 2+ for homing.
- Lower buildplate: Lower the print bed to the bottom.
- Raise build plate: Raise the print bed to the top.
- Insert material: Automatically heats the nozzle to load filament.
- Move material: Heats the filament to the target temperature, then rotate the knob to control the feeder motor to move the filament.
- Set fan speed: Control the speed of the fans on both sides of the print head.
- Retraction settings: Customize retraction settings.
- Version: Displays the firmware version of your Ultimaker 2+.
- Runtime stats: Displays the total power-on and printing hours of your Ultimaker 2+.
- Factory reset: Restores your Ultimaker 2+ to factory settings.
Fine-tuning
The Ultimaker2+ allows you to fine-tune settings during printing, giving you complete control over the printing process to help you achieve the best print results. Press the "Tune" option during printing to adjust various settings. The adjustable items are the same as those in the "Advanced" option, such as print temperature and print speed. Alternatively, you can press "Pause" to temporarily stop printing, change the filament, and then resume.
2. Changing Filament
What if you want to change the type or color of filament? Simply remove the existing filament and load a new one.
Removing Existing Filament
1. Enter the material change menu on the small screen by selecting "Material" > "Change".
2. Wait for the nozzle to heat up for about 1 minute to ensure the filament is melted before being retracted from the nozzle (the machine will perform this step automatically).
3. After the nozzle heats up, the feeder motor will automatically reverse and retract the filament. If it doesn't retract completely, you can manually pull out the remaining filament.
Loading New Filament
Reload the filament in the same way as the first time, ensuring the new filament is placed on the spool holder in the correct direction (counter-clockwise).
1. Cut the tip of the filament into a sharp shape.
2. Insert the filament into the feeder motor and push it until it is gripped by the motor.
3. Before the filament reaches the first bowden tube clip, press the knob next to the screen to continue automatic feeding.
4. After pressing continue, the filament will quickly feed to the nozzle.
5. Once the filament is automatically extruded from the nozzle, press the knob again.
Note! Do not touch the nozzle during heating to avoid burns.
Note! The color of the extruded filament may initially differ from the one you loaded. This might be residual filament from factory testing. Once the residual filament is completely extruded, the color will return to normal.
3. Print Bed Leveling
The levelness of the first print layer is crucial, so regular print bed leveling is recommended. Of course, if you find that objects can no longer be printed level on the bed, or if the machine has been transported, it is advisable to perform print bed leveling to ensure good adhesion of printed objects to the bed.
Please select "Maintenance" > "Buildplate" on the display. The print head will first automatically home, then move to the center-rear of the print area, and then you can begin adjusting the level.
Height Setting
This is the first step of leveling. Rotate the knob next to the screen to move the print bed until it is about 1mm from the nozzle, then stop. The exact distance is not critical, as long as the bed is close enough to the nozzle without touching it.
Initial Calibration
Perform preliminary calibration using the two adjustment screws at the front of the bed. Turning the knob to the left raises the bed, and to the right lowers it. Again, aim for a distance of approximately 1mm between the bed and the nozzle.
Fine-tuning
Use the calibration card for fine-tuning.
Place the calibration card between the print bed and the nozzle, then adjust the calibration screws while moving the card to feel the friction between the bed and the nozzle.
The nozzle will automatically select three points for you to repeat the same steps. Adjust the friction between the bed and the nozzle to be consistent.
Note!
Only slight friction is needed; do not over-tighten.
Do not push on the print bed during fine-tuning to avoid affecting accuracy.
4. Software and Firmware
For slicing software, we recommend the free software Cura, which can quickly and accurately slice your 3D models, allowing you to preview the print results and ensure accuracy in all details.
Installation
Download the Cura software from the Ultimaker official website to begin installation. The first time you open Cura after installation, you will be prompted to select a 3D printer. Choose Ultimaker2+ to start using the software.

Using Cura
1. Click "Load" to select your 3D object file (STL, OBJ, DAE, AMF).
2. Choose your desired settings, and Cura will automatically slice the model.
3. After slicing is complete, click "Save GCode" to save the file. It is recommended to save the file to the SD card.
4. After saving, remove the SD card and insert it into the Ultimaker2+ to start printing.
Updating Firmware
The Ultimaker official website regularly releases updated versions of Cura and the machine's firmware. Please check the official website frequently to ensure your software and firmware are up to date.
Please follow these steps to update the Ultimaker2 firmware:
1. Connect your computer to the Ultimaker2+ using a USB cable.
2. Connect the Ultimaker2+ power cable and turn on the power.
3. Open Cura, select "Machine" > "Install default firmware" (ensure that the Cura Machine menu displays Ultimaker2+). Cura will
automatically update your machine's firmware to the latest version.

5. Using Adhesives
Although the Ultimaker 2+ heated bed allows objects to adhere well, when using 3D printing materials with high shrinkage and a tendency to warp, it is still necessary to apply a thin layer of adhesive to the glass plate to enhance adhesion between the printed object and the glass plate.
When to Use
Depends on the material used and the size and shape of the object.
For example, ABS and CPE are recommended to use adhesive because they are materials that tend to warp. Plastics shrink when rapidly cooled, and some plastics shrink more significantly, leading to warping or curling of the bottom (corners) of printed objects. ABS and CPE belong to this category of plastics, so when using these plastics with higher shrinkage rates, adhesives are needed to prevent warping.
PLA plastic has a low shrinkage rate and hardly warps, so adhesive is not needed during printing. However, the glass plate should be kept clean, free of oil or dust, as these contaminants can prevent the plastic from adhering to the glass surface. Of course, there are situations where even PLA might require adhesive; if you are printing an object with a large and thin base, adhesive may be needed to prevent it from detaching.
How to Use
The Ultimaker 2+ comes with an adhesive stick. When using it, simply apply a thin layer of adhesive to the printing area on the glass plate before it heats up.
Tip! After applying the adhesive, you can use a damp cloth to lightly wipe it, allowing the adhesive to spread more evenly on the glass plate.

6. Changing Nozzles
The Ultimaker2+ nozzle set includes one each of 0.25mm, 0.4mm, 0.6mm, and 0.8mm nozzle diameters, with the 0.4mm nozzle already installed on the print head. You can easily and quickly change to a different nozzle diameter by following the steps below.
Removing the Existing Nozzle
1. Select “Material” > “Change” to remove the existing filament first.
2. Before removing the nozzle, perform the nozzle cleaning procedure to minimize the amount of residual plastic on the nozzle, which might affect subsequent prints with this nozzle.
3. Maintain the nozzle temperature at the temperature used during the nozzle cleaning procedure (e.g., PLA 90 degrees).
4. Use a hex wrench to rotate the nozzle counter-clockwise and remove it.
Installing the New Nozzle
1. Select the desired nozzle diameter and manually screw it in tightly. The heater block will still be hot, so be careful not to touch it.
2. Rotate the hex wrench clockwise to tighten the nozzle. Be careful not to over-tighten to avoid damaging the heater block.
Adjusting Cura Settings
Before printing, remember to adjust the nozzle diameter setting in Cura! Please note that the unit is mm!
