• Quiet TMC2660 stepper drivers, up to 256 micro-stepping.
• High speed uSD card and support for a second external SD card if required.
• Dual extruders controlled on the main board, up to 5 additional stepper motor drivers are controlled on the DUEX expansion board.
• High Power rating: Each stepper driver is capable of 2.8A motor current, currently limited in software to 2.4A.
• Access the printer via a PC, tablet or smartphone on a local network.
• Set up and control your printer through the web interface.

Fully Automated Calibration

All our printers’ models are delivered with the electronic expansion board named Duex. This allows allocating a dedicated
driver per each motor for both Z axis and X axis. As a result, Modix is now offering a full set of automated calibrations routines
including:

• Bed tilting calibration
• Bed leveling
• Gantry alignment
• Z offset calibration

IDEX dual printing add-on

“IDEX” stands for independent dual extruder, where each extruder is capable of moving independently from each
other. As a result, while the active extruder is printing, the second extruder is “parked” outside the printing area.
Therefore, dual material printing made with IDEX technology comes out cleaner and with higher success ratios
in comparison to other configurations as such the two print heads are installed side by side on the same carriage.

IDEX allows printing of advanced models that have internal geometries by using water-soluble filament. In addition,
printing the dense support layers (interface layers between the model and the solid support structure) with a breakaway
support filament, saves a lot of manual labor for support removal. In addition, since there is no need to keep air gap
between the dense support and the model itself as normally happened when using the same material for support, the
supported bottom surface of the models comes out clean and smooth. This saves a lot of time needed usually for
sanding during the post process.

The IDEX is sold as an optional add-on for all generation 4 printers. includes:

• Secondary printing subsystem: Griffin print head, clog detector, PTFE, spool mount.
• Motion system: secondary Y axis motor with the required components (belts, pulleys etc.).
• Metal brackets for both Y axis and print heads
• Wires, drag chains and optical end-stops.

Modix Advanced Soluble Filament

Automatic Filament Changer

Modix’s IDEX can also be used as an automatic filament changer. When using the same filament on both print heads,
the printer will be able to switch between the print heads automatically once one the printer detects a filament run-out.
Here are the benefits:

Get prints faster – One of the biggest challenges of 3D printing is the need to constantly monitor and maintain the printer.
This can be especially frustrating when the machine has to sit idle overnight while waiting to be fed with a new filament spool.
That’s where the Modix IDEX Filament Changer comes in. This clever technology allows the printer to switch out filament
spools on its own, without having to pause its operation and wait. That means you can keep your printer running around the
clock, without losing time on waiting for someone to service it.

Improved print quality – Not only does the Modix IDEX Filament Changer save you time, but it also helps to improve the quality
of your prints. By not having to open the enclosure for service, the printer is able to maintain its chamber’s temperature,
preventing the partly printed model from shrinking. This allows you to produce higher quality prints with fewer defects.
If you want to take your 3D printing to the next level, be sure to check out the Modix IDEX add-on.

Super High Flow Hotend

Super volcano hotend high flow is an optional add-on designed for customers who print large bulky objects and need to
print fast. It is also an excellent choice for printing thick vase mode style objects since the single walled objects are stronger.

This add-on is based on the E3D super volcano heat-block and nozzles. It is provided with 80W heater and a thermistor.
The new addition is now delivered with a mounting CNC made bracket. This mounting protects and stabilizes the long
heatblock during printing. As a result it provides high print quality as vibrations are minimized during accelerations.

Includes:

• • E3D SuperVolcano heater block
  • 1mm nozzle brass nozzle
  • Slice Engineering bi-metal heat-break
  • 80W heater
  • CNC adapter
  • Blower Fan & duct

Tilt Screen & Emergency Button & Frontal Power switch

This trio feature combo is available as standard for BIG-Meter and BIG-120Z and offered as an add-on for the
rest of the printers.

Tilt Screen – Mounted on an articulated arm, the tilt screen is a convenience feature. It is very useful during
print head calibration process and other maintenance routines as you can always turn the face towards you.
Left right, upwards or downwards.

Emergency Reset Button – Together with the tilt screen update, an emergency reset (software reset) button is
now located on the front of the machine. This control and safety feature will allow you to immediately stop
prints whenever needed.

Frontal Power Switch –easy to reach power on/off button. Useful when the printer is installed in a tight corner.

Removable Magnetic Bed

This add-on will greatly improve the user experience and save you time on a daily basis.  Modix’s printers are delivered by default with a
PEI sheet that releases the print once the bed is cooled down to room temperature. With the removable magnetic bed add-on, users do
not need to wait or work hard with a spatula and can easily and immediately remove objects after completing the print job by simply
bending the spring steel plate.

This add-on includes an adhesive magnetic sheet that should be fixed to the aluminum bed plate and a removable spring steel plate
that should be placed on top of it. The flexible spring steel plate can be printed on from both sides. One side is PEI powder coated
providing textured bottom surface and the other side is serviced with a smooth PEI sheet providing a glossy bottom finish.

Another advantage is with maintenance, the PEI installed on the bed plate can degrade over time. Print removal with a spatula may
result in unwanted scratches that later appear at the bottom of the printed object. Replacing the PEI on the removable spring steel or
even buying a spare unit is much easier than removing it from the bed plate itself.

Active Air Filter

The Modix Active Air Filter (MAAF) is an external air filter device. The filter cleanses the printers’ chamber by capturing
micro-particles and gas fumes that are released from melted filament throughout the 3D printing process. MAAF provides
a constant air cleansing process during the entire printing process, circulating the air in and out and back into the printer
while cleaning it repeatedly.

Multi-layer filtering
A large fan inside the device draws the air from the printer through a flexible vent tube connected to the top of the device.
The air is then guided through a set of three filters before it is circulated back into the printer.

The triple filter system includes
1. Pre-Filter – Remove large dust particles from the air.
2. HEPA Filter – High-Efficiency Particulate Absorbing (HEPA) filter, composed of a mat of randomly arranged fiberglass
fibers designed to capture tiny particles released during printing.
3. Active Carbon Filter – Clean the air from toxic fumes released during the 3D printing process.

It is about your health!
Sub-micron particles and fumes released during the plastic melting process pose risk to your health. Therefore, every
owner of a Modix 3D printer is strongly advised to install an air filter.  Air filter is a MUST-HAVE add-on if you intend to
print with any plastic beyond PLA, i.e. PETG, ABS… Although common knowledge is that printing PLA in a well-ventilated
room is fine, there is no clear definition of proper room ventilation and during the winter and summer times windows are
normally closed.

Controlling the air speed
Frontal speed selector allows controlling the air flow speed. Running the filter on the lowest speed during the printing
process will not affect the internal chamber temperature while providing effective filtering. By the end of the printing,
you can set the speed for the highest option for a few minutes in order to ensure the complete chamber has been
cleaned of any harmful additives opening the doors.

Spare Filters
Considering the daily use of the printer in a clean room, the HEPA/Carbon combo filters last from 6 to12 months
and the pre-filter from 3 to 6 months. An alert indicator to change the is located on the front panel.

Power Distribution Unit (PDU)

PDU is included by default with the BIG-Meter and BIG-180X due to their high current drawing requirements.
Since we have found it to be a very convenient cable management solution, it is now offered for all other models*.
Replace 3 AC cables with only one cable connected to the wall.

* This solution does not support BIG-120X running on 110V, please contact the sales team for an alternative solution.
