TRAK 3ntr 3D Printers –SPFU Installation Quick Start Guide
1Introduction
This guide outlines the process to install the Soft Polymer Feeder Unit (SPFU) to Nozzle #1 of your TRAK
3ntr A2 or A4 printer. Before you can install the SPFU, you must complete the Clean Nozzle procedure
(also outlined within this guide).
2Clean Nozzle Procedure
This section details all the steps to clean extruder nozzles. The nozzle cleaning procedure must ALWAYS
be performed BEFORE changing to a new polymer type filament. A nozzle cleaning procedure should
always be performed any time there are unacceptable nozzle flow conditions that cannot be cleared with
several purge cycles.
2.1 Clean Nozzle Procedure Overview:
There are three steps to cleaning nozzles;
1) Remove existing filament(s) using the change filament function
2) Feed cleaning filament (nylon) to the extruder(s)
3) Clean nozzle(s) using the front panel control Clean Nozzle function
CAUTION - Only load factory recommended (nylon or equivalent) filament for cleaning procedures.
NOTE - Before using the Clean Nozzle function from the front panel, you must use the Change/Load
Cleaning Filament procedure to remove build/support filament and feed the nylon cleaning filament to the
extruders to be cleaned.
2.2 Unload Filament Using Change Filament Function
In this section, you will change filament removing existing spools before installing the cleaning filament
(instead of a new build/support material filament spool). It should always be performed before a nozzle
cleaning procedure.
NOTE - If you are using an MMS unit or PolyBox (humidity-controlled container) the process is different.
If feeding material directly from a PolyBox or equivalent container, follow the instructions as applicable
1) Check that there is enough clearance (20-30mm) between nozzle and plate before starting. If
not, move printer plate following instructions for “Move Z axis function”
2) Navigate to the Prepare menu. From the Prepare menu select “Change filament”

3) Assuming filament has been previously loaded, Select Change Filament “Extruder #1”
Figure 2.2.2 Selecting Extruder for Change Filament
4) The selected extruder will begin heating up and the LCD will display Heating… Observe the
temperature readout for the selected extruder and see it increasing.
Figure 2.2.3 Info Display During Change Filament
5) Once the set temperature is reached, the machine will purge some filament. Once this automatic
purging is completed, the display will indicate “Unload Filament Now”. At this time, you can now
reach to the back of the cabinet to unload the filament.

6) Locate the feeder handle on the selected extruder. Grab the feeder handle of the selected
extruder, push it down and secure it into position with the provided lock “lip” This way the feeder
mechanism will be disengaged. Looking at the feeders from the rear of the printer, the rightmost
is the #1 feeder, and leftmost is #3.

7) Pull the filament from the feeder, rewinding the filament onto the spool.
Figure 2.2.7 Pulling old filament out of feeder unit
8) Thread the end through the opening on the spool to keep it from de-coiling.
Figure 2.2.8 Secure filament end to spool
9) Unlock and remove collar from filament spool spindle of selected extruder on back of printer.
Remove filament spool and place in a dry and clean container (with desiccant package) away
from heat and sunlight.

2.3 Load Cleaning Filament
1) Obtain the cleaning filament (Hollow nylon filament specially for nozzle cleaning).
Figure 2.3.1 Nozzle Cleaning Filament (Nylon)
2) Trim off several mm to remove bends, dirt, tape, or damage. Straighten as needed.
Figure 2.3.2 Trim off the end of new filament
3) Use scissors, knife, or a pencil sharpener to point the filament end for easy feeding to the
extruder.

4) Feed the filament into the feeder unit and keep feeding until the end stops at the extruder.
Release the feeder handle. Verify the locking “lip” is disengaged.
Figure 2.3.4 Engage the filament feeder
5) The locking lip is now engaged. The machine will automatically control the filament feed.

6) Press the button on the jog wheel. The LCD will display “Priming #X” as it purges some filament.
Upon completion, the LCD will display “Change #x Complete” to indicate completion.

7) Repeat filament change/load cleaning filament procedure for extruder #2 (as necessary)
8) Repeat filament change/load cleaning filament procedure for extruder #3 (as necessary)
9) Procedure complete!
2.4 Nozzle Cleaning (Automated Function)
This section details the nozzle cleaning procedure. The nozzle cleaning procedure must ALWAYS be
performed BEFORE changing to a new polymer type filament. A nozzle cleaning procedure should always
be performed any time there are unacceptable nozzle flow conditions that cannot be cleared with several
purge cycles.
NOTE - Before using the Clean Nozzle function from the front panel, you must use the Change Filament
procedure to remove build/support filament and feed the nylon cleaning filament to the extruders to be
cleaned.
1) Use CHANGE FILAMENT/Load Cleaning Filament procedure (see appropriate guide section for
instructions) to remove filament in use and to load cleaner filament to the machine.
