This Initial Set-Up & Calibration Guide covers the basic steps required to set-up, calibrate, and operate a
new TRAK 3ntr A2/A4 printer and optional MMS unit from uncrating through to printing test parts. These
basic steps are outlined in the Initial Printer Set-Up & Calibration Checklist, below. Advanced set-up,
printer re-configuration, and repair maintenance procedures are not included within this guide.
This guide contains instructions to operate the TRAK 3ntr A2/A4 3D printers to simplify initial set-up and
calibration for factory trained technicians. It is not intended for customer use. Upon successful
completion of the initial set-up, calibration, and test prints, the customer should be encouraged to use
the simple and straightforward Printer & MMS Operation Quick Start Guide to get started, and the (full)
Printer & MMS Guide for those topics not covered in the QS Guide.
NOTE - The completeness and level of detail for set-up, calibration, operation, and maintenance
procedures within this guide is limited. Where additional information is required please consult the (full)
Printer & MMS Guide, Maintenance Manual, or specific procedure/work instruction documents.
CAUTION - Section 2 contains important safety information, it is highly recommended that all personnel
and operators review and understand this information before starting. Only qualified and trained
operators should use this Initial Set-Up & Calibration Guide.

2Safety
The safe set-up, calibration, and operation of your TRAK 3ntr 3D printer depends on its proper use and
precautions taken by each operator. If these activities are performed incorrectly, there are risks, not
limited to, electric shock, pinch/crush, burns, inhalation of fumes/debris that can cause serious injury or
death.
Read and follow this Initial Set-Up & Calibration Guide. Understand the printer operation and safety
precautions before setting up, calibrating, or operating the 3D printer.
•Always wear safety glasses and safety shoes.
•Always stop the printer before opening the access door and reaching into the printer.
•Always allow the printer, printer surface plate and workpiece to cool adequately before reaching
into the printer.
•Have a qualified electrician make all electrical connections and cable wiring
•Never wear gloves, rings, watches, long sleeves, neckties, jewelry, or other loose items when
operating the printer.
2.1 Safety Precautions
1) Do not operate this machine before the TRAK 3ntr Safety, Installation, Maintenance, Service and
Parts List Manual, and the Safety, Programming, Operating & Care Manual have been studied and
understood.
2) Do not run this machine without knowing the function of every control key, button, knob, or
handle. Ask your supervisor or a qualified instructor for help when needed.
3) Protect your eyes. Always wear approved safety glasses (with side shields) .
4) Allow the machine to cool before reaching into it for any reason. The printer bed, printer surface
plate, printed part, extruders/nozzles, and other printer interior components can reach very high
temperatures and cause serious burns.
5) Don't get caught in moving parts. Before operating this machine remove all jewelry including
watches and rings, neckties, and any loose-fitting clothing.
6) Keep your hair away from moving parts. Wear adequate safety headgear.
7) Protect your feet. Wear safety shoes with oil-resistant, anti-skid soles, and steel toes.
8) Take off gloves before you start the machine. Gloves are easily caught in moving parts.
9) Remove all tools (wrenches, check keys, etc.) from the machine before you start. Loose items
can become dangerous flying projectiles.
10) Never operate a 3D printer after consuming alcoholic beverages, or taking strong medication, or
while using non-prescription drugs.
11) Protect your hands. Stop the printer bed movement and extruder translation mechanism:
a. Before opening the printer access door
b. Before reaching into the machine for any reason
c. Before changing parts
d. Before removing the printer bed tray, printed parts, or filament debris
e. Before you make an adjustment to the extruder, nozzles or any interior mechanism.
12) Protect your eyes and the machine as well. Don't use a compressed air hose to remove the
debris or clean the machine.
13) Stop and disconnect the machine before you perform maintenance and calibration operations.
14) Keep work area well lighted. Ask for additional light if needed.
15) Do not lean on the machine while it is running.

16) Prevent slippage. Keep the work area dry and clean. Remove obstacles of any kind around the
machine.
17) Avoid getting pinched in places where the printer bed or extruder arm movement can cause a
crush or pinch injury
18) Do not operate the printer with the printer access door open or any of the windows or service
access panels removed.

3.1.2 Lifting and Moving Printer
Figure 3.1.3 Moving Printer with Fork Truck (Secured to Pallet)
3.2 Uncrate & Unpack MMS Unit (If Applicable)
1) Use a fork truck to move the MMS unit as close as possible to the final location before
uncrating or removing from the pallet. The MMS unit has wheels and can be rolled on flat
level surfaces as needed.
2) Remove shipping screws holding top portion of MMS shipping crate to base
3) Lift off the top portion of the shipping crate from base
4) Remove ratchet straps
5) Set-Up a table or desk nearby for placing the printer/MMS/print server components during
the unpacking and set-up process.
6) Place materials from on top of MMS and place on a table
7) Remove protective bubble wrap and foam protection from MMS
8) Roll MMS Unit off the shipping pallet and on to the floor
9) Open access door to MMS. Remove the contents and place on a table (You may elect to wait
to perform this step later, such as after the printer has been placed on the MMS and when
ready to install the HEPA filter)
10) Remove protective plastic from MMS windows
CAUTION!
The A2 Printer should be moved by forklift or pallet jack ONLY when mounted on a pallet.
•The printer will be damaged if moved by forklift without the pallet attached.
•Once the pallet has been removed from the printer it must be moved by hand.
•Orient the printer with the sides or front facing the fork truck - The feeder mechanism and filament
spool holders on the rear of the printer protrude and can be damaged
•3 or 4 people are required move the A2 printer by hand - lifting it onto the printer stand, table, or
MMS.

3.3 Uncrate & Unpack Printer
CAUTION - After uncrating printer, DO NOT lift printer directly with forklift or slings. The printer
calibration and/or printer housing will be damaged if excessive force is exerted at any location other than
the four printer feet. Lift by hand with 3 or preferable 4 people if necessary. Replace printer onto
shipping pallet before using fork truck or lift.
1) Use a fork truck to move the printer unit as close as possible to the final location before
uncrating or removing from the pallet. The printer has fixed feet (not casters) thus must be
lifted and carried to its final position.
2) Remove shipping screws holding top portion of printer shipping crate to base
3) Lift off the top portion of shipping crate from base
4) Remove contents of printer and place on table.
5) Remove protective wrapping from outside printer
6) Open the access door to the printer bed and identify the protective materials and film at all
locations inside. Remove protective materials and plastic film from all printer windows and
access doors.
NOTE - Protective film must be removed or it will melt from the heat during the printing
process, causing damage to the printer.
3.4 Locate Printer and MMS Unit/Printer Stand in Final Location
If doing so, ensure the table or stand is rated for the weight of the printer and materials (A2=50 kg/A4 =
130 kg), is sufficiently flat, properly leveled, and is sturdy enough to prevent movement or vibration
during printing.
1) Move MMS Unit or Printer stand to desired location.
2) Lock wheels on MMS Unit or Printer Stand to prevent movement.
3) Get 3 or 4 people to lift the printer.
4) Place printer on MMS Unit/Printer Stand

5Install HEPA Filter
In this section, we will install/connect the HEPA filter Unit. Proper connection is required to remove
contaminants and maintain printer chamber temperatures during printing.
5.1 Install HEPA Filter (Common to MMSV2 & External Filter Unit)
NOTE –The final steps of HEPA Filter installation differ if; A) using an MMS V2 Unit that incorporates a
permanently affixed, internal HEPA filter unit OR B) if using a printer stand or no MMS unit. Determine
which instructions Section 5.2 (MMS2 V2) or Section 5.3 (External HEPA Filter Unit) are applicable and
follow them for completion.
Figure 5.1.1 HEPA filter unit within MMS V2
1) If using an external HEPA filter unit, then locate the air filter package including filtering unit,
filter cartridge, and power supply. Not applicable for MMS V2
