Maintenance

Clean the feeders on the Ultimaker 3

January 30, 2020 11:34

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 turn smoothly.

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. In addition to blowing out the

particles once a month, it is recommended to also clean the inside of the feeders after

one year of printing. 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:

Remove the material by navigating to

Material/PrintCore -> Material [x] -> Unload

. After

this, turn off the printer

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

Reduce the tension of the feeder by turning the bolt in the top of the feeder, until the

indicator is at the highest mark

Use the hex screwdriver to loosen the two bolts that hold the feeder to the back panel

and slide the feeder backward away from the printer

Open the feeder by removing the four bolts that hold the housing parts together.

Place the two halves in front of you, making sure that all parts are in the back section

of the feeder

Use a clean cloth or a cotton swab to wipe all filament particles from the feeder parts.

Use a paintbrush or an old toothbrush to clean the knurled wheel. Also clean the

small gear attached to the feeder motor

Apply a small amount of Magnalube 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

Reassemble the feeder by placing the front section over the back section, making sure

that all parts are still in place. Insert the four bolts and tighten them in a cross

pattern, starting in the top-left corner

Place the feeder back on the printer

10.

Insert the Bowden tube into the feeder by pressing down on the tube coupling collet

in the feeder and pushing the Bowden tube all the way in. Secure the tube with the

clamp clip

11.

Reset the tension of the feeder by turning the bolt in the top of the feeder, until the

indicator is at the middle mark
