Lubricating the axles

To maintain your Ultimaker 2 Extended+ correctly and keep it running smoothly, it is recommended to lubricate the axles periodically.

X and Y axles

When you notice small ridges on the surfaces of your 3D printed objects or feel that the X and Y axles are dry, it is advised to put a single drop of sewing machine oil onto the X and Y axles. This will help your Ultimaker 2 Extended+ to run smoothly. Sewing machine oil is not included in the Ultimaker 2 Extended+ package, but we highly recommend using only this to lubricate the X and Y axles.

Important: Don't use WD40 as this will affect the coating that is on the axles. We advise to only use sewing machine oil for oiling the axles.

Z trapezoidal leadscrew

Once every 6 months, the Z trapezoidal leadscrew has to be lubricated with Magnalube. This is the green grease that was delivered with your Ultimaker 2 Extended+. Spread 10 drops of grease over the entire threaded rod. With your next print, the Ultimaker 2 Extended+ will lubricate the axis by moving up and down.

Note: Magnalube should be applied to the Z trapezoidal leadscrew only; do not put it on any of the other axes.
