5.11 Clean the feeders
The feeders forward filament to the print head. To make sure that exactly the right amount of material is extruded,
it is important that the feeder gears can smoothly turn.
After many hours of printing, or when material has been ground down, there is a chance that there are small
filament particles in the feeders. It is recommended to clean the inside of the feeders after three months. In order
to do this, the feeders have to be removed from the printer.
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 clips from both sides of the feeder, press on the tube coupling collet, and pull the Bowden
tubes out of the feeder. Next, remove the two tube coupling collets
3. Reduce the tension of the feeder by turning the bolt in the top of the feeder with the hex screwdriver, until the
indicator is completely at the top
The hex screwdriver that was supplied with the Ultimaker S5 cannot be used for this action in combination with
the Air Manager. Use a 2 mm hex key instead.
4. Use the hex screwdriver to loosen the four bolts of the feedder housing
5. Carefully pull the front part of the feeder away from the printer and put it aside
Be careful not to lose the ring that is located at the bottom of the feeder. If it falls out, place it back in the
feeder housing with the widest side at the top.
6. Use a small brush to gently clean all filament particles from the knurled wheel, the flow sensor axis, and the
inside of the feeder housing
7. Place the front part over the feeder again and firmly push it into place. Insert the four bolts and tighten them in
a cross pattern, starting in the top-left corner
8. Insert the tube coupling collets into the feeder and push the Bowden tubes from the Ultimaker S5 and the
Material Station all the way in. Secure the tubes with the clamp clips
9. Reset the tension of the feeder by turning the bolt in the top of the feeder, until the indicator
is at the middle mark
5.12 Clean the print cores
Maintenance of the BB print core should be performed once every three months, or after 400 printing hours. Using
the Ultimaker cleaning filament is the most effective way to clean and unclog the BB print core on the Ultimaker S5.
If you don’t have the Ultimaker cleaning filament at your disposal, you can use PLA instead.
Cleaning filament can be used to clean the print core on an Ultimaker S5 by applying hot and cold pulls. Hot pulls
are used to get the biggest parts of degraded material out of the print core and are especially necessary when
a print core is clogged. With a cold pull, the remaining small particles will be pulled out, ensuring the print core
is completely clean.
If necessary, you can also use this method to clean an AA or CC print core. The AA print cores do not require
preventive maintenance. The print core CC Red 0.6 benefits from preventive maintenance once a month, or
after 150 printing hours.
