Safety Instructions
Building the printer will require a certain amount of physical dexterity, common sense and a
thorough understanding of what you are doing. We have provided this detailed instruction to help
you assemble it easily.
However, ultimately we cannot be responsible for your health and safety while you are building or
operating the printer. Therefore, be sure you are confident in what you are doing prior to
commencing with building or buying. Read the entire manual to enable you to make an informed
decision.
Building and operating involves electricity and all necessary precautions should be taken and
adhered to. The printer runs on 24V supplied by a certified power supply, so you shouldn’t ever
have to get involved with anything over 24V. Please bear in mind that there can still be high
currents involved and even at 24V they shouldn’t be taken lightly.
Check the power input of the power supply unit. You can choose either 110V or 220V according to
the power regulation in your country.
High temperatures are involved in 3D Printing. The extrusion nozzle of the hot end can run at about
230°C, the heated bed runs at 110°C and the molten plastic extruded will initially be at around
200°C. Therefore, special care and attention should be taken when you are handling these parts of
the printer during operation.
We wouldn’t suggest you to leave your printer running unattended, or at least until you are
confident to do so. We are not responsible for any loss, damage, threat, hurt or other negligent result
caused by either building or using the printer.

www.geeetech.com
14
ShenZhen GETECH CO.,LTD
4.1 Use Repetier-Host to Test
4.1.1 Motor Direction Test
Manually set the motors of X / Y / Z axis in the middle of each direction to avoid accidental
collision during the test. Always be prepared for emergency stop. There is emergency stop button at
the top right corner , or you can cut off the power.
Start Repetier-Host and connect the printer. Click Home button , then all three axes will
move towards the endstop. After hitting the endstop, they will move back for a short distance and
then stop the movement. The origin location should be in the right front corner of the printer
platform.
www.geeetech.com
15
ShenZhen GETECH CO.,LTD
Note: The origin of the coordinates is at the front left corner of the building platform.
Therefore, when X/Y/Z axis is homed, there coordinates are X=230mm, Y=150mm,
Z=0mm.
In this way, the positive direction of X axis is from left to right, i.e. +1mm means the motor
moves toward the X axis endstop at 1mm.
The positive direction of Y axis is from outside to inside, i.e. +1mm means the motor moves
toward the Y axis endstop at 1mm.
The positive direction of Z axis is from up to down, i.e. +1mm means the motor moves
away from the Z axis endstop at 1mm ( move down).
www.geeetech.com

So far, functional tests of the printer are done.
5. Hotbed Leveling
Before printing, we need to do hotbed leveling. Only after this step can quality of printed parts get
improved. Otherwise the un-leveling gap between the hotbed and extrusion head will affect the
filament adhering to the hotbed thus cause poor print quality or even not printing.
(1) Initially, home the printer.
www.geeetech.com
37
ShenZhen GETECH CO.,LTD
(2) Disable the stepper motors , manually move the extruder to the four corners of the hot bed
and fine-tune the wing nut at each corner to level the distances between the extrusion head and
four corners. During adjustment, you can put a piece of A4 paper (half fold it) between the
nozzle and hotbed. If you can feel a bit friction when you pull the paper back and forth, the
distance is proper.
www.geeetech.com
38
ShenZhen GETECH CO.,LTD
www.geeetech.com
39
ShenZhen GETECH CO.,LTD
www.geeetech.com
40
ShenZhen GETECH CO.,LTD
www.geeetech.com
41
ShenZhen GETECH CO.,LTD
If the friction is moderate, it means that the distance between the nozzle and building
platform is adequate.
If there is an obvious gap, it means the distance between the nozzle and the build platform
is too far. Under this condition, the extruded filament will not be closely attached to the
building platform. You need to rotate the wing nut at the leveling point anti-clockwise to
reduce the distance.
If you can’t see any gap, it means the distance between the nozzle and building platform is
too close. Under this condition, the filament can’t be extruded out or can even be jammed.
You need to rotate the wing nut at the leveling point clockwise to increase the distance.
(3) Dual-extruder leveling. Duplicator 5 uses MK8 dual-extruder, so you only need to adjust the
two set screws when leveling the extruder, as marked in following picture. You can take one
hotend as a reference when you are doing the adjustment. Loosen the corresponding set screw
www.geeetech.com
42
ShenZhen GETECH CO.,LTD
clockwise to increase or decrease the height of the other hotend.
With the above three steps, we have finished the leveling job. It is suggested to move the nozzle to
the center of the building platform to test whether the building platform is level.
6. Slice Settings
With one more step, we can start printing. Set the slicing parameters such as filament diameter,
printing speed, layer height, etc. to achieve better print quality. Open slic3r, a piece of slicing
software built in Repetier-Host. The following picture shows the operation flow.
www.geeetech.com
