Security » Intended Use
Version 1.0 5 von 25
SECURITY
1. Intended Use
3Dfeedy is designed exclusively for the home user in the hobby and do-it-yourself sector for the
following purposes:
• multi-filament printing
• number of filaments dependent on number of Feedy units; 3Dfeedy intended for 3 filaments.
• compatible filament is dependent on your 3D-printer.
All other applications are expressly excluded and are considered to be non-intended use. The
manufacturer or dealer accepts no liability for injuries, loss or damage caused by non-intended or
incorrect use.
Possible examples of non-intended or incorrect use are:
• use of the 3Dfeedy for purposes other than those for which it is intended;
• failure to observe the safety instructions and warnings, as well as the assembly, operating,
maintenance and cleaning instructions contained in this operating manual;
• failure to observe any accident prevention, occupational health or safety regulations specific
and/ or generally applicable to the use of 3D-printing equipment;
• use of accessories and spare parts not intended for the 3Dfeedy;
• modifications to the 3Dfeedy;
• repair of the 3Dfeedy by someone other than the manufacturer or a specialist;
• commercial, craft or industrial use of 3Dfeedy;
• operation or maintenance of 3Dfeedy by persons who are not familiar with the handling of the
feeder and/or do not understand the associated hazards.
Despite intended use, non-obvious residual risks cannot be completely ruled out.

Preparation 3D-Printer » Disconnect Power Supply
Version 1.0 6 von 25
PREPARATION 3D-PRINTER
The following steps are explained in general, as they are applicable the same way to any 3D-printer.
However, the pictures are shown as an example based on Ultimaker 2+, which makes the individual
steps probably look slightly different.
We cannot give any warranty for your 3D-printer. However, if you follow all the steps carefully
and take care of yourself and your printer, no damage is expected.
As you are installing 3Dfeedy to your 3D-printer, you have to make sure your 3D-printer does
have a CE-Conformity.
1. Disconnect Power Supply
Disconnect your 3D-printer from the power supply.
Failure to follow the instructions for proper set up, use and care for your device can increase the
risk of serious personal injury, death or property damage.
2. Unplug PTFE Tube
• Unplug the PTFE tube from the extruder.
• Unplug the PTFE tube from the printhead.
For unplugging the PTFE tube, usually a release button has to be used.

Preparation 3D-Printer » Remove Extruder
Version 1.0 7 von 25
3. Remove Extruder
• Unscrew the screws of the extruder.
• Remove the extruder.
i It could look different with your 3D-printer to the visualization shown above.
4. Remove Drive Gear
• Remove the drive gear from the extruder drive motor.
In some cases, an additional stud screw has to be removed or loosened.
i It could look different with your 3D-printer to the visualization shown above.
i Sometimes, the drive gear already fits to the drive gear of 3Dfeedy (e.g. Ultimaker 2+), which
makes it unnecessary to change it. You can check this by comparing the additional drive gear
from the box with the mounted one of your 3D-printer.
If the drive gear is tight fit to the extruder drive motor, do not damage the extruder drive motor.
Please purchase a new extruder drive motor with equal settings of the existing extruder drive
motor.

Assembly 3Dfeedy » Connect Drive Gear to Extruder Drive Motor
Version 1.0 14 von 25
ASSEMBLY 3DFEEDY
Now 3Dfeedy is ready for marriage:
1. Connect Drive Gear to Extruder Drive Motor
i You may use the extruder drive motor from your 3D-printer uninstalled in chapter “Preparation
3D-Printer”.
i Alternatively, a new extruder drive motor can be bought and used for further steps.
If a new extruder drive motor was bought, make sure it has equal settings to your extruder drive
motor for not damaging the mainboard of your 3D-printer.
• Connect the drive gear from the box to the extruder drive motor by pushing it on the shaft if
necessary.
i Take a close look at the flat shaft of the extruder motor drive to correctly align and connect the
drive gear.

Version 1.0 15 von 25
2. Connect Extruder Drive Motor to Cover of Drive Unit
• Put the drive unit cover on the extruder drive motor.
i If the extruder drive motor is of the size NEMA 14 or NEMA 11 go to step 2.1 and take a closer
look on how to install these extruder drive motors.
i If the extruder drive motor is of a different size than NEMA 11, NEMA 14, NEMA 17, probably a
new drive unit cover has to be prepared in advance.
i If the motor shaft is too long use spacer between extruder drive motor and drive unit cover. This
will be shown in detail in the instruction “3Dfeedy Spacer Instruction Manual”.
• For NEMA 17 insert and tighten three M3x6 screws hand-tight with the Allen key to fix the
extruder drive motor to the drive unit cover.
2.1. Connect other Extruder Drive Motor sizes to Drive Unit Cover
• If the extruder drive motor is of the size NEMA 14, use the holes highlighted in red and fix the
extruder drive motor with four M3x6 screws from the box hand-tight with the Allen key.
• If the extruder drive motor is of the size NEMA 11, use the holes highlighted in purple and fix the
extruder drive motor with four M2.5x6 screws from the box hand-tight.
i If the motor shaft is too long use spacer between extruder drive motor and drive unit cover. This
will be shown in detail in the instruction “3Dfeedy Spacer Instruction Manual”.

…
• Connect the extruder drive motor with the drive unit cover to 3Dfeedy.
• Insert and tighten the two M3x6 screws hand-tight with the Allen key to fix the extruder drive
motor to 3Dfeedy.
• Insert a M3 hexagon nut from the box to the groove.
i If the steps of the manual “3DFeedy Spacer Instruction Manual” has been followed, sometimes
the hexagon nut is already installed.

Assembly 3Dfeedy » Insert Selector Shaft
Version 1.0 17 von 25
4. Insert Selector Shaft
• Insert the selector shaft to 3Dfeedy.
Be careful when inserting the selector shaft for not damaging the housing at the transmission
unit!
• After inserting the selector shaft carefully rotate it slightly to fit the highlighted area of the
selector shaft to the drive gear.
• If there are collisions when inserting the selector shaft, the components on the shaft may be
slipped and have to be repositioned during insertion.
• Try to rotate the manual adjustment wheel until the selector shaft starts to rotate.
i Slightly press in the selector shaft at the bearings to avoid it from pushing out.
i If the selector shaft starts to rotate, the selector shaft is correctly oriented.
i If the selector shaft does not start to rotate and the selector shaft is pressed out even though it
is fixed with your hands, the selector shaft is probably wrong oriented and the step marked in
violet should be repeated. This can usually also be seen when the bearing does not fit at all in
the groove.
