After calibrating the build plate with the first nozzle, the second nozzle needs to be aligned as well, to ensure the heights of
both nozzles are set correctly. For this it is only necessary to set the correct height by using the calibration card.
1. Place the calibration card between the second nozzle and build plate.
2. Rotate the button at the front of the Ultimaker 3 until it touches the calibration card and fine-tune it until you feel slight
friction/resistance when moving the card.
There should always be a distance of 14 mm between the bottom of the heated bed and base plate to prevent
errors during active leveling.
Leveling frequency
The Ultimaker 3 will ask how often you want to level your build plate, once you have leveled it.
These are the options:
• Every day
• Every week
• After startup
• Never
• Automatic (the leveling frequency is determined by the printer, based on the amount of printing hours since the last
time the build plate was leveled)
You can always change the leveling frequency by going to System g Build plate g Frequency in the menu.
Z oset calibration
The last part of the manual leveling procedure is the Z offset calibration. This ensures that the correct vertical distance
between the two nozzles is stored. This procedure can also be done separately.
1. Go to System g Maintenance g Calibration g Calibrate XY offset.
2. Place the calibration card between the second nozzle and build plate.
3. Rotate the button at the front of the Ultimaker 3 until it touches the calibration card and fine-tune it until you feel slight
friction/resistance when moving the card.
XY oset calibration
Besides the vertical offset, the horizontal distance between the nozzles, in the X and Y direction, also needs to be
stored. The print cores that are supplied with the Ultimaker 3 are already calibrated, but when the printer detects a
new combination you have to do an XY offset calibration first. This calibration must only be done once; after this, the
information is stored on the printer.
A correct XY calibration will ensure that the two colors or materials align well.
The AA print core that was installed on receipt of the Ultimaker 3 has already been calibrated with the other AA and BB
print core and does not require calibration.
To do the calibration you will need the XY calibration sheet, which you can find in the accessory box or download here.
If you need to print it, make sure you print it on an A4 paper at 100% scale.
Ensure 2 print cores and materials are installed before starting the calibration.
