Manual Nozzle Height Calibration
To manually determine the correct nozzle distance, please follow these steps:
1. Open the Maintenance dialog box from the 3D Print menu and click the Center button. The
current nozzle height is indicated as shown in the Maintenance dialog images below. In the
Windows example, the platform is currently at the bottom of the printer; the Mac example
has the platform 135.5mm from the bottom.
2. Enter the height to which you want the platform to move to into the textbox and click the To
button. In the above Windows example, the platform will move to 121 mm above the
platform’s origin. In the Mac example, the platform is already at the height selected.
3. Check the distance between the nozzle and the print surface. If the platform is currently at
121mm and appears to be about 12mm away from the nozzle, change the number in the
text box to by 9mm to
130 and click the To button. Use small increments from this point to
avoid striking the print surface into the nozzle.
4. Once the print surface is about 1mm away from the nozzle, increase the number in the text
box by 0.1mm increments and click the To button. Repeat until the print surface is 0.2mm
from the nozzle.
TIP: An easy way to check the
distance between the nozzle
and print surface is to fold a
piece of paper in two, which will
be about 0.2mm thick. Use this
as a spacer to gauge the
distance between the nozzle
and print surface.
5. Once you have the print surface
within 0.2mm of the nozzle, click the
Set Nozzle Height button to save
the current nozzle height.
6. Check the nozzle height at all four corners of the platform. Repeat the Nozzle Height
Calibration and Platform Leveling processes if needed.
You may need to recalibrate the nozzle height if the models are not adhering to the print
surface properly or are warping. It is also recommended after moving the printer or
changing the print surface.
TIP: If the print surface contacts the nozzle while making height adjustments, it is good practice to
re-initialize the printer and before undertaking any other operations.
