Ultimaker S5 Material Station User manual

Ultimaker S5
Fine knurl feeder kit
Notes
Caution: Make sure the laments are removed, the Ultimaker
S5 is turned o, and the power cable is disconnected from the
printer before you start the replacement.
Introduction
This document describes how to replace both of the feeders of the Ultimaker S5. A new feeder with a ner knurled wheel was developed
to improve printing with PVA on the Ultimaker S5 Pro Bundle. The ne pattern of the knurled wheel reduces stress on the PVA material
and prevents it from breaking inside the Material Station. These new feeders are strongly recommended for the Ultimaker S5 Pro Bundle if
PVA is used regularly.

Requirements
For this repair, you need a new set of feeders (provided
in the Fine knurl feeder kit) and a 2 mm hex screwdriver.
Optionally, you can use grease to perform maintenance
on the feeder gear while performing this replacement.
The screwdriver and grease were included in the
Ultimaker S5 accessory box.
• Fine knurl feeder left (1)
• Fine knurl feeder right (2)
• 2.0 mm hex screwdriver
• Magnalube grease (optional)
Note: Both of the feeders must be replaced. The two versions
cannot be mixed on the same printer. Keep the ne knurl feeders
in the kit until the old feeders have been removed. Ensure to
keep them separate.
The new feeders have been marked with a black dot on the back.

Tip: Only pull the Bowden tubes out of the feeders, but leave them in
the Material Station’s decouplers
Note: Do this for both of the feeders
1. Remove the power extension cable between the
Ultimaker S5 and the Material Station
Note: The Ultimaker S5 Pro Bundle does not need to be dismantled
for this repair. Only follow the steps described here
The following steps describe which actions are required if a Material Station was already installed. If you are a new Material Station user, go direcly
to the next page and follow the steps before installing your new Material Station.
5. Pull the tube coupling collets out of the bottom
of the feeders and set them apart
Note: These collets will be placed in the new feeders when
reconnecting the Material Station
