GOOD 3D PRINTING PRACTICES
Before Printing
1. Ensure that your gcode file is correctly setup, with the filament diameter set to
1.75mm and the correct temperature settings for the type of filament you are
printing.
2. Check that all cables and connectors are properly connected.
3. Check that the Heated Build Plate is level and approximately 0.1mm from the nozzle.
4. Check that the Heated Build Plate is clean and dust free, and that the nozzle does
not have excess material stuck to it.
During Printing
1. Closely monitor the first layer being printed. Most problems will occur in the first
layer. If problems occur, stop the print process, remove the extruded filament, fix
the source of the problems, then restart the print.
2. Do not leave the 3D printer unattended during operation.
3. Keep your hands clear while the machine is printing.

10
After Printing
1. Wait for the Heated Build Plate, Extruder, and printed model to cool before
attempting to remove the print.
2. Carefully remove the 3D object. Never direct the scraper towards your fingers or
body. Keep the scraper evenly flat when scraping to avoid damage to the Heated
Build Plate and the Print Mat, which will affect adhesion for future prints.
3. Store the 3D printer in a clean, dry environment.
4. Store any unused filament in a manner that will not allow it to be exposed to
moisture or humidity. For best results, use a vacuum sealed plastic bag with a silica
gel pack inside to absorb any residual moisture.
ASSEMBLY AND MOUNTING
Remove all parts from the box and place them on a
flat work surface. The parts pictured are the base, the
two Z-axis pillars, the X-axis gantry, the X-axis rail,
and the MK12 extruder.

11
Place the base on its side. Locate the Z-axis pillar with
the sticker No.2. Slide the No.2 pillar into the base
vertical locker, then tighten the bolt at the bottom of
the base.
Tighten the locking bolt by turning it clockwise, then
flip the base onto its other side and install the other
Z-axis pillar onto the base using the same method.
Turn the base so that it rests on its feet and the Z-axis
pillars are vertical. Loosen the two locking bolts at the
top of the two Z-axis pillars (marked No.3 and No.4)
by about 5mm, so there will be sufficient space for
the X-axis gantry to slide in.

12
Remove the plastic end caps from the X-axis gantry,
then slide it under the bolt heads and locking
washers. Ensure that the No.3 and No.4 stickers are
mated. If there is insufficient space for the gantry to
fit under the bolt head, loosen it a bit more and try
again.
Insert the hex screw driver through the holes in the top
of the gantry and tighten the hex bolts. Double check
all bolts to ensure that they are tight and that the
gantry, pillars, and base assembly is steady and tight.
Insert the plastic end caps onto the ends of the X-axis
gantry.

13
Screw the X-axis spacers (No.5 and No.6) onto the X-
axis rail, but do not tighten them so much that the
spacers cannot move along the rail.
Mount the X-axis rail assembly by inserting the X-axis
spacers in between the rubber wheels on the Z-axis
steppers. You may need to slide the spacers a bit to
one side or the other. Ensure that the X-axis rail is
mounted symmetrically and that the extruder holder
is facing the front of the printer.
Using two hex bolts, secure the X-axis spacers to the
Z-axis steppers.

14
Insert the MK12 extruder into the extruder holder on
the X-axis rail.
Using the four remaining hex bolts, secure the
extruder the X-axis rail assembly in four places, two
on each side.

15
WIRING
Connect the wires and
cables as shown in the
image to the left. Route the
ribbon cable through the
ribbon cable clips before
connecting it at each end.
AUTOMATIC LEVELING
Turn the couplers on the Z-axis steppers to make the X-axis rail level. Use a small level on
the X-axis rail to ensure that it is level. It must be level for proper bed calibration.

16
Plug the included AC power cord into the printer,
then plug the other end into a nearby AC power
outlet. Flip the power switch on the printer to turn it
on. From the Home page on the printer screen, select
Level > Auto level to initiate the automatic bed
leveling procedure.
Note: Once the auto leveling is complete, the printer
will remember the leveling data for future printing.
You don't have to level the bed each time, unless you
feel it may not be leveled. Auto leveling is for general printing purposes. If you need some
special layer thickness or other special purposes, you may need to adjust the four bolts
under the bed to achieve a more precise distance.
If auto leveling doesn't meet your needs, choose the Manual level option and follow the
instructions that will appear on screen.
Congratulations, your new 3D printer is now ready for use!
MANUAL LEVELING
While automatic leveling is sufficient for most tasks, manual leveling can achieve more
accuracy for printing at higher resolutions. Perform the following steps to manually level
the build plate.
1. With the printer turned on, press Utilities > Change Filament > Raise Extruder to
raise the extruder to allow easy access to the build plate.
2. Turn the printer off.
3. Use a small level to ensure that the X Axis rail is level. If it is not level, turn the Z Axis
Lead Screws on either side until it is level.
4. Squeeze each corner of the build plate and tighten the nut to lower the build plate.
5. Wipe the build plate with a clean, dry, lint-free cloth to remove any dust.
6. Turn the printer on.

17
7. Once the printer has finished initializing, press Utilities > Home XYZ to move the
extruder and build plate to the home position.
8. Turn the printer off.
9. With the power turned off, manually move the extruder to each corner and to the
middle of the build plate. Use a sheet of ordinary printing paper to check the
distance between the build plate and the extruder nozzle. Loosen the knobs at each
corner to reduce the distance between the build plate and the extruder nozzle until
there is some slight resistance to moving the paper. Keep adjusting and testing until
the proper gap is present at all points.
ADDING FILAMENT
Preform the following steps to insert filament into the extruder.
1. 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. Place the spool on
the Filament Holder.
2. Squeeze the filament feed lever on the extruder, insert the
filament into the hole on top of the extruder, then release
the lever to lock the filament in place.
3. Turn the printer on and allow it to finish initialization.
4. Press Utilities > Change Filament > Add Filament. The printer
will automatically preheat and then feed filament into the
extruder. Press the Back button after several centimeters of filament have been
extruded.

18
REMOVING FILAMENT
Perform the following steps to remove filament from the extruder.
1. With the printer turned on and initialized, press Utilities >Change Filament >
Remove Filament. The printer will automatically heat and, once the target
temperature is reached, will remove the filament from the extruder.
2. Store any unused filament in an airtight bag. For best results, store it in a vacuum
sealed bag with a silica gel pack to remove any residual moisture.
