Lubricate the lead screw of the Z motor

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.

Note: Because the amount of Magnalube supplied with the Ultimaker 3 is more than sufficient for one year of maintenance for the printer, it is not included in the Maintenance Kit.

  • Make sure that the bed 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.
