Lubricate the S-line axles

To make sure that your print head and Z stage can move smoothly at all times, it is advised to lubricate the axles every month. This is normally only necessary after the first year of printing. If the axles feel dry, this can show in your prints as small ridges on surfaces. Apply some oil to the axles at least once a month.

A bottle of oil is included in the accessory box of your Ultimaker S3 or Ultimaker S5. This oil is specifically for the smooth axles of the printer. Only use the supplied oil, as using other oils or grease may affect the coating of the axles, which can affect the performance of your printer.

Caution: Before you start, turn off the printer or ensure it is disabled in the Ultimaker Digital Factory to prevent new print jobs from starting remotely.

X and Y axles

First, check if the axles are clean. If necessary, use a paper towel or microfiber cloth to wipe any dust or dirt from the axles. Then, apply a small drop of oil to each of the X and Y axles as well as both print head shafts. Manually move the print head around to evenly distribute the oil.

Note: Do not apply too much oil to the axles, as it might drip from the axles onto the build plate, which will affect print adhesion. If a drop of oil falls on the build plate, clean it thoroughly before printing.

Z axles

Apply a small drop of oil to each of the Z axles. In the Ultimaker menu, go to Configuration - Build plate. Select Raise and then Lower to move the build plate up and down in order to evenly distribute the oil.

Note: Do not apply the oil to the Z motor's lead screw. This must be lubricated with the supplied grease once every three months.

Note: Never use the grease (Magnalube or Eurol) on the smooth axles of your printer. If you have done so accidentally, make sure to thoroughly clean the shafts before applying the oil for relubrication.
