7 Load Filament/Materials

In this section, you will load filament to the back of the 3ntr printer or into the MMS Unit. The printer is
delivered with 2 spools of ABS/ASA filament suitable for initial set-up calibration and test prints. For
simplicity, use this material.

NOTE – If only unloading filaments/materials from an extruder that will be left empty, you can select the

“Unload filament” function instead, then subsequently perform a “Purge filament” function from the LCD

Prepare Menu.

CAUTION - Only load filament for materials suitable for the 3ntr A2/A4 printers. If necessary, review the
datasheet or materials profiles within KISSlicer to determine acceptable filament types. If you are
changing the polymer type, you must perform a nozzle cleaning procedure before starting a change
filament procedure.

7.1 Load Filament to Back of Printer

This section details the process to load filament onto the back of the printer.

NOTE - If you are using an MMS unit or Humidity Controlled Container (humidity-controlled container)
the process is different. If feeding material directly from a Humidity Controlled Container or equivalent
container, follow the instructions as applicable (new filament spool is not mounted on printer). With an
MMS unit, follow the applicable portions of the instructions below.

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 either the “Change filament” (if

filament was previously loaded) or “Load filament” (if empty) function.

Figure 7.1.1 Selecting Function Change Filament

3) Assuming filament has been previously loaded, Select Change Filament “Extruder #1”

Figure 7.1.2 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 7.1.3 Confirming Selected Nozzle Temperature is Increasing

5) Once the set temperature is reached, the machine will purge some filament. Once this automatic

purging is completed, the display will indicate “Change Filament Now”. At this time, you can now
reach to the back of the cabinet to begin the physical filament change.

Figure 7.1.4 Heating/Purging Completed -Ready for Physical Filament Change

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.

18) Machine is now ready!

7.2 Loading Filament/Material into the MMS Unit

Loading Filament/Material to the MMS Unit differs only a little from the process of loading material to the
back of the Printer detailed in the section: Load Filament/Materials. Please follow the instructions from
that section, making the following adjustments for the MMS Unit.

Key differences are highlighted here:

• Filament spools are located within the MMS instead of the back of the printer

• The MMS spool holders (loose pieces/not attached) are threaded through filament spools and

secured with a locking pin.

Figure 7.2.1 Placing Filament Spool & Holder in MMS Unit

• The spool holders rest on support arms (weigh scales) within the MMS

• The filament must be fed through the openings in the MMS and/or the PTFE tubing from MMS to

the filament feeder.

23

TRAK Machine Tools

Southwestern Industries, Inc.

TRAK 3ntr 3D Printers – Printer & MMS Operation Quick Start Guide

Figure 7.2.2 Pulling Filament from MMS up to Feeder

• After loading materials into the MMS, make sure they are not tangled, and close the door quickly

to avoid increasing the humidity inside.

• You must access the MMS Server and click the Dash button to add/select materials and set spool

sizes for the actual material loaded in each extruder/storage position.

NOTE - This step is needed to ensure the materials loaded match what is viewable from the print
server.

CAUTION - If you fail to update the MMS Server with the filament spool details after loading,
bad prints may result because of insufficient filament or mistaken filament size/type (does not
match g-code print file).

7.3 Filament Care/Storage

In this section, we will highlight basic 3D print materials care/storage instructions.

NOTE - 3D printing materials are vulnerable to humidity, temperature, and contamination, with some
materials much more sensitive than others. The best way to care for and store 3D print materials is
within the MMS unit. If you are using a Humidity Controlled Container or MMS unit, and the MMS unit is
powered and maintained, no other steps are required. If no MMS is used, or materials are removed from
the MMS after use, please follow these instructions to maintain the quality of subsequent prints.

1) Consult and follow the manufacturer’s recommendations for individual filament type care/storage.

2) Keep filaments within their sealed packaging until immediately before use.

8 Purge Nozzle/Filament

In this section, you will complete a common operation performed BEFORE changing to a different
material and when nozzle flow issues are observed. TRAK 3ntr printers are typically delivered without
any filament installed/remaining in the extruder. Check and if there is filament in the extruder, you must
perform a Purge #1 and Purge #2 operation as described in this section.

NOTE – The Change filament or Load filament functions automatically perform a purge operation after
new materials is loaded using the automatic function. Additional purge cycles (as described in this
section) may be required until the expelled material no longer contains material previously loaded.

CAUTION – Before purging nozzles, check to verify there is adequate clearance between the extruder
and the printer surface plate. Use the Move Z axis function (instructions above) to jog down if necessary.
If desired for the purged material to flow onto the printer surface plate, or to observe the flow, use the
Move X and/or Move Y functions to position extruders over the desired location.

CAUTION – Before purging nozzles, verify the default purging temperature (245° C) is acceptable for
the material in use, otherwise use a custom purging routine/temperature. The default setting is
acceptable for the ABS/ASA materials that ship with the printer.

1) Begin by pressing the black button to enter the Main printer menu (from the information display).

Turn the jog wheel until the selector points to the Prepare menu, then press the black button to
select. Scroll down the menu until the selector points to the Purge filament menu and press the
black button to select.

9 Clean Nozzles

This section details all the steps to clean extruder nozzles. Nozzle cleaning is commonly performed when
changing filaments, if undesirable flow conditions are present, or during routine printer maintenance, set­up, and/or installation activities. When required, each nozzle must be individually cleaned.

NOTE - 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. Nozzle cleaning may also be
required during common maintenance and print job set-up procedures such as a nozzle change, installing
and SPFU, reconfiguring extruders, and more.

9.1 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.

9.2 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”

Figure 9.2.1 Selecting Change Filament from Prepare Menu

9.4 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.

10 MMS Unit Operation

This section provides information regarding the use and operation of the MMS Unit after initial set-up.

10.1 MMS Overview

The TRAK Plural Material Management System v2 is designed to properly store a range of materials ready
for feeding or fed to the printer from a humidity-controlled environment which insures optimum print
quality and part performance. With the server installed and connected to your network, both the
browser-based remote dashboard and the touchscreen on the MMS will display live material quantity
readouts in meters or grams for each of 6 spools of material.

Please review the information in this guide to take best advantage of the MMS and its functionality. See
“Controlling the RH in the Cabinet” later in this document for details on maximizing the performance of
the cabinet and desiccant.

10.2 Power ON the MMS Unit

NOTE: The MMS power switch should not be used to shut down the server. Before turning off MMS

power, shut down the MMS server (“sudo shutdown now”) and power off the printer using the printer’s

power switch or emergency stop button. (the MMS touch screen is powered by the MMS server.

10.3 MMS Touch Screen Control

The touchscreen displays live readouts from the MMS’s 6 material feed storage positions, and
configuration data of the printer’s 3 nozzles, and prompts you when printer configuration or material
changes need to be made on the printer (as entered into the MMS dashboard application).

Figure 10.3.1 MMS – Update Required

Figure 10.3.2 MMS Touch Screen

10.4 MMS Dashboard

Click the Dash button if needed to switch to the data entry mode to add materials, set spools sizes and
store nozzle configuration information.

TRAK Machine Tools

Southwestern Industries, Inc.

TRAK 3ntr 3D Printers – Printer & MMS Operation Quick Start Guide

Figure 10.4.1 Locating the MMS Dash Button

On the Dash page you can enter additional materials and edit any existing information. Remember that
you’ll need to know the specific gravity or density of each material entered to get reasonably accurate
material remaining estimations.

Remaining filament on each spool is calculated by using the empty weight of the spool along with the live
weight and material information entered for that spool. The server keeps a running average of the empty
spool weight, so if you know an empty spool weight has changed enter it into the field for the spool,
otherwise no entry will use the default average empty spool weight for that spool size.

After you make changes on the Dash page, the cabinet’s touchscreen will prompt you to confirm that the
changes have been made on the printer to ensure that the actual setup matches the MMS Server’s data.
