The lead screw is connected to the Z motor and controls the movements of the Z stage. To ensure smooth movement of the Z stage, it is recommended to periodically apply Magnalube to the lead screw.
Over time, Magnalube may need to be reapplied to maintain consistent and accurate movement of the Z stage. A tube of Magnalube is included in the Accessory Box of your Ultimaker 3.
- Make sure that the build plate is positioned at the bottom of the Ultimaker 3
- Apply a small amount of Magnalube to the lead screw of the Z motor
- In the Ultimaker menu, go to System -> Build plate
- Select “Raise” and then “Lower” to move the build plate up and down to evenly distribute the Magnalube
Caution: Do not use Magnalube on the smooth axles, this will affect the working of your Ultimaker 3.
