5.13 Lubricate the feeder gear
To ensure the feeders forward the filament smoothly and accurately, the gears are lubricated. After many hours of
printing, it is recommended to reapply this lubrication. As small filament particles may have stuck to the gears, it is
advised to clean them first.
It is also recommended to replace the Bowden tubes after one year. While lubricating the feeder gears, follow
the instructions to simultaneously replace the Bowden tubes.
The following steps need to be performed for both feeder 1 and feeder 2:
1. Turn off the printer and remove the power extension cable
2. Remove the clamp clip from the feeder-end of the Bowden tube, press down on the tube coupling collet and
pull the Bowden tube upwards out of the feeder
3. Use the hex screwdriver to loosen the two bolts that hold the feeder to the back panel
4. Carefully move the feeder away from the back panel and disconnect the filament detection cable
from the flow sensor
5. Use a clean cloth or a cotton swab to wipe all filament particles and grease residue from the feeder gears.
Clean both the gear connected to the motor and the larger gear inside the feeder
6. Apply a small amount of grease to the gear attached to the feeder motor. There is no need to spread this out;
the feeder will do this automatically when it turns
7. Hold the feeder close to the back panel and connect the filament detection cable to the flow sensor
8. Place the feeder back on the printer and secure it with the two bolts
9. Push the Bowden tubes from the Ultimaker S5 and the Material Station all the way into the tube coupling
collets. Secure the tubes with the clamp clips
5.14 Replace the Bowden tubes
This only applies to the Bowden tubes on the Ultimaker S5, between the feeders and the print head. The
Bowden tubes of the Material Station do not require regular replacement.
The Bowden tubes guide the filament from the feeders to the print head.
Forwarding improperly cut or ground down filament through the Bowden tube could scratch or damage the inside
of the tube. If this happens, the filament can no longer be smoothly forwarded to the print head. This can lead to
under-extrusion or other print quality issues.
After removing a Bowden tube multiple times, the tube coupling collet can wear out. If this happens, the tube
coupling collet will no longer have a firm hold on the Bowden tube. In this case, the Bowden tube will move up and
down during prints, which can negatively impact print quality.
If the Bowden tubes are permanently damaged, they need to be replaced. To maintain optimal print quality. it is
recommended to replace the Bowden tubes every year.
Disassembly
1. Open the cover of the Air Manager
2. Place the print head in the front-right corner
3. Use your fingernail to remove the clamp clips from the tube coupling collets at the print head and feeders
4. Press down on the tube coupling collet in the print head and at the same time, pull the Bowden tube upwards,
out of the print head. Repeat these steps for the feeders
5. Loosen the four cable clips from the Bowden tube (extruder 2)
6. Guide the Bowden tubes through the mounting bracket of the Air Manager to remove them
