Lubricate the S-line lead screw

The lead screw is connected to the Z motor and controls the movements of the Z stage. Over time, grease may need to be reapplied to maintain consistent and accurate movement of the Z stage. 

It is recommended to check the lead screw once every three months and reapply the grease when necessary. A tube of grease is included in the accessory box of your Ultimaker S3 or S5.

  1. Make sure that the build plate is positioned at the bottom of the printer
  2. Wipe the lead screw with a cloth or paper towel to remove as much of the old grease as possible
  3. Apply a small amount of grease to the lead screw of the Z motor
  4. In the Ultimaker menu, go to Configuration > Build plate
  5. Select Raise and then Lower to move the build plate up and down to evenly distribute the grease

Note: Only use the grease on the lead screw of the Z motor. Never apply grease to the smooth axles of your printer.


Tip: The image above shows Magnalube grease, which has a green color. Ultimaker recently switched to a different brand of grease (Eurol). Both grease types can be used for maintenance of your Ultimaker S-line printer.
