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 calibra-
tion card.
Place the calibration card between the second nozzle and build plate.
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.
Press the button to confirm and complete the calibration process.
CAUTION: Do not push on the build plate while fine-tuning with the calibration card. This will lead
to inaccuracies.
Z offset calibration
The last part of the manual leveling procedure is the Z offset calibration. This ensures that the correct vertical dis-
tance between the two nozzles is stored. This procedure can also be done separately.
Go to System > Maintenance > Calibration > Calibrate XY offset.
Place the calibration card between the second nozzle and build plate.
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 offset 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. This is only necessary for new
combinations.
A correct XY calibration will ensure that the two colors or materials align well.
To do the calibration you will need the XY calibration sheet, which you can find in the accessory box. You also
need to make sure two print cores and materials are loaded.
To start the calibration:
1.
Go to System > Maintenance > Calibration > Calibrate XY offset.
2.
The Ultimaker 3 will now print a grid structure on the build plate. Wait until it is finished.
3.
Once the Ultimaker 3 has cooled down, remove the glass plate from the printer and place it on the
XY calibration sheet. Ensure the printed grid it is exactly placed on the two rectangles on the sheet.
4.
Find the aligned lines on the printed X grid and look which number belongs to these lines. Enter
this number as the X offset value on your Ultimaker 3.
5.
Find the aligned lines on the printed Y grid and look which number belongs to these lines. Enter
this number as the Y offset value on your Ultimaker 3.
