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 grease to the lead screw. Over time, grease may need to be reapplied to maintain consistent and accurate movement of the Z stage.
A tube of grease is included in the accessory box of your Ultimaker 2+ Connect.
Note: Do not use this grease on the smooth axles of the Ultimaker 2+ Connect; this will affect the performance of your printer.
Caution: Turn off the printer or ensure the Ultimaker 2+ Connect cannot accept new print jobs through the Digital Factory.
- Make sure that the build plate is positioned at the bottom of the Ultimaker 2+ Connect
- Apply a small amount of grease to the lead screw of the Z motor
- Move the build plate up and down to evenly distribute the oil. This can be done manually, or through the Maintenance → Move build plate menu
