SETUP
Warning! Take care not to remove or damage the yellow tape on the build platform. This
tape is essential to ensure the 3D model properly adheres to the build platform during
printing. If this tape becomes damaged or wears out, replace it with painter's tape,
Kapton® tape, or ordinary masking tape.
Perform the following steps to prepare the printer for use.
1. Remove the printer from its packaging and place it on
a flat, stable surface with plenty of ventilation and a
nearby AC power outlet.
2. Open the Accessories box and remove the Filament
Rack. Slide the tab at the flat end into the slot on the
left side of the printer frame.
3. Ensure that the power switch on the rear panel is in the OFF position (Oside
depressed). Plug the C13 end of the included AC Power Cable into the C14 panel
connector on the AC Power Adapter, then plug the other end into a nearby AC
power outlet. Depress the Iside of the power switch to power the printer ON.
4. Rotate the control wheel clockwise to move
the highlight to the Move entry, then press the
center of the control wheel to open the Move
menu.
5. Rotate the control wheel clockwise to move
the highlight to the Home Axis entry, then
press the center of the control wheel to activate the Home Axis function. The
printer will move the extruder head to the "home" position.
6. Turn the printer off by depressing the Oside of the power switch.
7. Slide a sheet of A4 paper between the build platform and the extruder nozzle. The
extruder height above the build platform should be 0.05mm, which is the thickness
of a sheet of A4 paper. The extruder is at the correct height when the sheet of

8
paper can be slid between the nozzle and the
platform without binding. When the extruder
head is moved or when the paper is moved
under it, there should be a slight amount of
resistance, but the paper should not be
dragged with the extruder when it is moved.
If the height is incorrect, use the included hex
wrench to make slight adjustments to the
platform height by turning the screws at each
corner of the platform. Turn the screws
clockwise to lower the platform and
counterclockwise to raise the platform. Turn
the wrench no more than 1/4 turn each time,
then recheck the height. Continue checking
and adjusting until the height is correct at all
points on the platform.
8. Insert the included microSD™card into the slot
on the right side of the printer.
9. Turn the printer on by depressing the Iside of
the power switch on the rear panel.
10. Rotate the control wheel clockwise to
highlight the Temperature entry, then press
the control wheel to open the Temperature
menu.
11. Use the control wheel to highlight the Extruder
entry, then press the control wheel to edit the
value. Rotate the control wheel to set the
temperature to the target temperature for the
type of filament you plan on using.
12. Using the same procedure, set the Platform temperature to the target temperature
for your filament type.

13. If the button under the Extruder and Platform reads Start Preheat, use the control
wheel to highlight the Start Preheat entry, then press it to start preheating the
extruder and build platform. The button will change to read Stop Preheat and the
Extruder and Platform buttons will read the actual temperatures.
14. While the printer is heating, open your filament. Using a pair of scissors or side
cutters, diagonally snip the end of the filament to make a point, as shown in the
images below.
15. Using the control wheel, navigate to the Move menu, then select the Z Axis option
and press the wheel. Turn the control wheel counterclockwise to raise the extruder
off the build platform.
16. Place the filament reel on the filament rack on
the left side of the printer.
17. While squeezing the lever on the Feed
Mechanism, insert the filament and push it into
opening. Keep pushing until you feel resistance
as it hits the extruder. Release the lever on the
Feed Mechanism.
18. Using the control wheel, highlight the Extruder
entry on the Move menu. Press the control
wheel, then turn it counterclockwise to feed
filament into the extruder. Continue until
filament starts to extrude out of the nozzle.
Wait until filament is no longer coming out of
the nozzle.

19. Using the included plastic scraper, clean the extruded filament from the nozzle and
build platform.
20. Using the control wheel, select the Print option
from the main menu. The printer will read the
contents of the microSD™card and display
them on screen. Highlight the cat.gcode file,
then press the control wheel to start printing
the model.
21. After the first layer has been laid down, use
the control wheel to Pause or Cancel the
printing operation. Examine the layer and
compare the printed material with the images
in the table below. If the result is wrong, turn
off the printer and re-adjust the platform
height as indicated. Clean off the printed material using the included plastic scraper,
then print the model print again. Keep repeating this process until the result is
correct.
Wrong
The nozzle is too far from the
platform. This can result in the
extruded material not sticking to the
build platform.
Correct
The nozzle is at the correct height
above the platform.
