Factor 4 - Lift switch calibration
The switch bay in the front-right corner of the gantry enables the second print core to be lifted and lowered. It is important that print core switching functions well for active leveling and a correct nozzle alignment in dual-extrusion prints. The lift switch is already calibrated at the factory, but calibration can also be performed manually if needed.
It is recommended to perform this calibration in the following situations:
- After replacing the gantry or replacing / adjusting components on the gantry
- After replacing the print head
- When the print core in slot 2 is not lifting and lowering correctly
Instructions
In the Settings menu, go to Maintenance → Print head → Calibrate lift switch and select Start calibration. Open the glass door of the build chamber and follow the instructions on the display.

1. Move the switch | 2. Move the print head Manually move the print head toward the switch bay in the front-right corner of the gantry. Ensure that the lift switch is placed inside the switch bay. Select Confirm to continue. | 3. Align the switch Gently pull the print head forward to ensure that the lift switch is placed correctly. Ensure to not bend the switch bay. Select Confirm to continue. | 4. Check the switching The printer will next perform a nozzle switch. It is important to closely observe the print head to check if the nozzle switching is done correctly. Select Start Lift Switch and watch the print head. |
If the lift switch is correctly moved to the front and back, select Confirm to complete the calibration process. If this is not the case, select Try Again to repeat the calibration steps.
Did the lift switch move to the front and back again correctly, but you do not observe the print core in slot 2 raising and lowering as expected, there could be a problem with the lift switch mechanism inside the print head. Please contact support for further assistance.
