2 OVERVIEW
The Mojo system builds models from CAD STL files that are sent to the system using a USB cable from a
dedicated host computer. The printer builds three-dimensional parts by extruding ABSplus model material and
SR-30 support material through two computer-controlled print heads, producing high quality parts that are ready
to use immediately after completion.
The Mojo system consists of two consumable QuickPack Print Engines. One QuickPack Print Engine contains
ABSplus model material and the other QuickPack Print Engine contains SR-30 support material.
Print Wizard is the preprocessing software that runs on Windows 7 or Windows 8 platforms.
Mojo builds a maximum part size of 127 x 127 x 127 mm (5 x 5 x 5 in.). Each QuickPack Print Engine contains
1311 cm³ (80 in³) of material and the extrusion head.
Power Requirements: 100-240V~, 6-3A, 50/60Hz

PROCESSING YOUR STL FILE FOR PRINTING
OPENING PRINT WIZARD
Create an STL file using your CAD software. Refer to your CAD software help section for more information
about converting your CAD drawings into STL files.
There are several ways of starting Print Wizard:
• From the Start Menu, select Print Wizard and then select one or more STL files from the STL
file list. Holding the Ctrl key down allows the selection of multiple parts. Use the Windows
Explorer tool bar to select the viewing options.
• From Windows Explorer, select the path where you store your STL files and then double-click a
single STL file to open.
• From Windows Explorer, select the path where you store your STL file and using the Windows
Explorer function, select several STL files. Use Ctrl left-click to select more than one STL file.
Right-click and select Print 3D to open the files.
Select Large Icons or Extra Large Icons to view thumbnail images of the parts.
SELECTING A PRINTER

connected to the printer in the boxes provided, and then press OK or from the menu on the Mojo control panel
on the host computer.
Figure 4-18: Entering an IP address
18
Page 25
SELECTING SUPPORT STYLE
Supports are used to support the part during the build process. Supports are removed when the part is
complete. Support styles will affect the support strength and build time of the print. SMART support is the default
setting.
Figure 4-19: Support style
• SMART (default) - Minimizes the amount of support material used, reduces the print time, and
improves support removal for many parts. SMART support uses a consistent spacing between
support toolpaths and is less dense than Basic.
• Basic - May be used for most parts. Basic support uses a consistent spacing between support
toolpaths.
• Surround - The entire part is surrounded by support material. Typically used for tall, thin parts.
19
Page 26
SELECTING PART INTERIOR
Model interior establishes the type of fill for the interior solid area of the part. Solid is the default setting.
Figure 4-20: Part Interior
‘
• Solid (default) - Fills the part completely for the most durable parts. Build times will be longer.
• Sparse - Low Density - A lower density part interior for the shortest build times and lowest
material use.
SELECTING DISPLAY UNITS
Display units can be selected for English or Metric measurement. The STL file selected will display the size of
the part under the file name. Display units determines whether the part size is displayed in millimeters or inches.
The unit selected will also be reflected in material information in the Mojo Control Panel window.
Figure 4-21: Display units
20
Page 27
SELECTING THE ORIENTATION OF YOUR PART
The orientation function displays an expanded preview window that shows the orientation of the part when it
prints. Orientation impacts build speed, part strength, surface finish and material consumption.
Figure 4-22: Part orientation
You can change the orientation of your part by clicking the Orient Part button and then selecting the orientation
desired from the preview window. The selected part can be further manipulated by using any of the X, Y, or Z
axis slide controls or by adding a specific value. When the desired orientation is achieved, click OK to save the
settings.
Icon Description
Rotates the displayed part around the X axis.
Rotates the displayed part around the Y axis.
Rotates the displayed part around the Z axis.
Orientation considerations
• Build Speed/Material Usage A lesser amount of supports will allow for a faster build speed.
Another factor affecting build speed is the axis orientation. The printer can build faster across
the X-Y plane than it can along the Z axis. Orienting a part so that it is shorter within the printing
chamber will produce a faster build.
• Part Strength - A part is stronger within a layer than it is across layers. You may need to orient
your part to have its greatest strength across a specific area. For example a tab that needs to
be pressed would be weakest if you are applying pressure across layers.
• Surface Finish - Orientation will affect the surface finish in specific areas of the part. How the
part is oriented will determine how the surface finish will look and allow the printer to provide the
smoothest finish for a specific area. For example, if printing a cylinder, orienting the cylinder
upright will have a smoother surface finish than printing it on its side.
21
Page 28
ROTATING THE PART VIEW
Left click on the part and then drag the mouse to the left or right to rotate the view within the chamber. This will
provide viewing of the front, left side, back, and right side views of the part(s) being printed.
Figure 4-23: Rotating the view
SELECTING THE SCALE OF YOUR PART
Before you process a part for printing, you can change the size of the part within the build chamber. If parts are
too large to fit in the build chamber when the STL file is first loaded, they are automatically scaled to fit the build
chamber. If the part is automatically scaled to fit the build chamber, the scale box will turn red. The part size can
be changed by entering a scale number or by using the slider control. Every part has a pre-defined size within
the STL file. After you have opened the file you can change the size of the part produced by changing the scale.
The scale always relates to the original STL size of the part as defined in the STL file.
Figure 4-24: Scaling
22
Page 29
For example: a cube that is defined as 5.1 cm (2 in.) X 5.1 cm (2 in.) X 5.1 cm (2 in.) can be built to be 10.2 cm
(4 in.) X 10.2 cm (4 in.) X 10.2 cm (4 in.) by simply changing the scale to 2. If after changing the scale to 2, you
decide that a size of 7.6 cm (3 in.) X 7.6 cm (3 in.) X 7.6 cm (3 in.) would be preferred, change the scale to 1.5 the scale relates to the original size of 2 inches, NOT the resulting 4 inches from the first scale change.
SELECTING THE NUMBER OF COPIES
Users may choose the number of copies (parts) to be printed. The printer will automatically calculate the number
of parts that can be printed on the modeling base. As the number of copies are increased, the printer may add
another job.
Figure 4-25: Number of copies
23
Page 30
JOB CREATION
Print Wizard automatically calculates the size and number of parts that can be printed on the modeling base. If
the size and number of the part are too large, Print Wizard will add another job.
The number of jobs created is based on:
• Part dimension
• Part orientation
• Scale
• Number of copies
Figure 4-26: Job added
Note: All jobs displayed will be sent to the host computer when the Print button
is clicked.
24

Maintenance purge is a way to verify that a QuickPack is extruding correctly or to purge out wet material from
the filament tube. It takes two maintenance purges to purge out all of the material in the filament tube. The
maintenance purge will purge material into air in the center of the build area. After a maintenance purge
completes, it is necessary to open the printer door and remove the purged material from the center of the build
area.
Note: If an opened QuickPack Print Engine has not been used in over two
weeks, two maintenance purges should be performed.

Mojo uses soluble support material which is designed to dissolve in a water based solution. Your part is left with
a smooth and clean finish with the fine details intact. The soluble support material can be removed by hand with
relative ease, but is designed to be dissolved from your parts for hands free finishing.
POWERING OFF
To power off the printer, turn the power switch to the OFF position. This can be done at anytime without harming
the printer. No other steps are necessary. If power is switched OFF while printing, the current part will not be
completed.
REMOVING THE QUICKPACK PRINT ENGINE
1. Open the cover.
2. Open the material sensor lid and remove the material tube guide from the material sensor.
3. Open the head socket lid and remove the print head.

5 MAINTENANCE
PREVENTIVE MAINTENANCE
DAILY
EMPTY THE PURGE BUCKETS
Empty the purge buckets after each build has completed.
INSPECT THE TIP WIPE ASSEMBLY
After each build you should inspect the tip wipe assembly to make sure there is no material build up. If there is
material build up, clean the tip wipe assembly by brushing it off. Material build up on the tip wipe assembly can
cause part quality issues.
AS NEEDED
REMOVE DEBRIS BUILDUP
Remove all material buildup on the platen and surrounding area. Failure to do so could cause part quality
issues.
CLEAN DOOR
Wipe clean using mild soap and a damp cloth. Do not use ammonia based glass cleaner on the door. It will
damage the polycarbonate window.
REPLACING TIP WIPE ASSEMBLY
The tip wipe assembly should be replaced with each QuickPack Print Engine replacement.
1. Open the door.
2. Lift out the tip wipes out from the holding bracket. There are two tip wipes; one on either side of
the chamber.
Figure 5-62: Removing tip wipes (right side shown)
3. When replacing the tip wipes make sure they are fully seated in the holding brackets.

6 TROUBLESHOOTING
GENERAL
Many printer issues can be resolved by pressing Resume in Mojo Control Panel or by cycling power.
CYCLING POWER
1. Turn the printer power switch to the OFF position.
2. The printer will shut off and the LED display will go blank.
3. Wait 20 seconds and turn the power switch to the ON position.
4. The display LEDs will blink in sequence during startup and when complete the display will turn
green indicating that the printer is in idle mode.
CLEANING HEAD TIPS
Occasionally excess material may build up on the head tips. Remove the excess material by gently scraping the
head tips using a small flat bladed screwdriver. Use care not to damage the head tips.
LOSS OF EXTRUSION
Occasionally, the head may experience a loss of extrusion. This will be evident by observing one of the
following:
• The head is moving with no material coming out of either tip.
• The height of the model and support materials are not equal.
• Structures are sagging due to lack of material.
If loss of extrusion continues to occur, replace the QuickPack Print Engine.
EXTRUSION VERIFICATION
Maintenance purge is a way to verify that a QuickPack is extruding correctly. See “Maintenance purge” on page
33.
