There are six tags in total here. Configure relevant parameters of the printer here.
4.2Connection
Choose right Port and Baud Rate. For other parameters please leave them as default, and click
Apply.
Port ：Get the printer connected to the port of computer, which is corresponding to the USB
Serial Port in the Device manager.
Baud Rate: Corresponding to the Baud Rate in firmware. Generally it is set as 250000.

www.geeetech.com
Shenzhen Getech Technology CO.LTD
Note: If the operating system is Mac OS, please set the baud rate as 115200. Meanwhile, you need
to do debugging for the motor direction of the printer again after re-uploading the firmware.
Open the firmware in Arduino 1.0.1, change the baud rate of firmware to 115200 in
Configuration.h file.
After modification, re-upload the firmware. About how to burn the firmware, please refer to the
FAQ.

www.geeetech.com
Shenzhen Getech Technology CO.LTD
After successfully modifying the baud rate in firmware, modify the baud rate in Repetier-Host
to 115200 as well.

4.3Printer
Set the extruder’s moving speed both in horizontal direction and Z-axis direction in the Printer tab,
and click Apply.
Travel Feed Rate: 4800mm/min
Z-Axis Feed Rate: 100mm/min
This is the default printing speed of Repetier-Host. You can adjust these two speeds if you need. But
please note that too fast print speed will lower the print quality.

5. Function Test
The uploaded firmware of Me Creator before delivery is based om Windows operating system, and
we have done debugging on it to make sure that every part of it can work normally. However, there
may be abnormal circumstances because of the process of transportation or other unpredictable
factors. Please do simple test before using it.
5.1 Use Repetier-Host to Test
5.1.1 Motor’s running direction test
Before the test, manually set the motors of X / Y / Z axis at the intermediate position of each axis in
order to avoid accidental collision occurring during the test. There is emergency stop button in the
top right corner , or you can cut off the power. Be prepared for emergency stop. Open
Repetier host and connect the printer. Click Home button , then three axes will move towards
the endstop. After they touching the endstop they will move back for a short distance and then stop
the movement. If the moving direction is reversed, you can change the direction in firmware.(please
refer to FAQ)

5.1.2 Heating function test
Click the heating button of the hot bed and the extruder . When the icon changes into
the state as shown below, it indicates the heating is ongoing.

www.geeetech.com
Shenzhen Getech Technology CO.LTD
Meanwhile you can see the temperature at the bottom of Repetier. If the hot bed or extruder can not
be heated, please refer to FAQ.
5.1.3 Extruder test
Please note: It is set in the firmware that the extruder will not work before the temperature reaches
above 170℃. Therefore, please heat the hotend above 170℃before testing any motor inserted in
the extruder’s port. Otherwise motor will not have any response.
First we raise the temperature to 200℃, then click the downward arrow and it begins extrusion.
Click the downward arrow to test if the extrusion of filament 0 is fluent or not. In order to avoid
blockage, please extrude filament at 1mm or 0.1 mm. You can use one hand to hold the filament so
that you can easily know the situation of motor’s rotation and filament’s movement.

5.2 Use LCD for Test
5.2.1 Homing
LCD>Prepare>Auto Home
Turn on the printer, first please make a homing. If you don’t make a homing, it will choose the
current position as home position by default. Debugging has been done on Me Creator before its
delivery, and the homing direction is toward the endstop under normal
situation.

www.geeetech.com
Shenzhen Getech Technology CO.LTD
5.2.2 Heating
LCD>Prepare>Preheat PLA/Preheat ABS
Test the heating function of hotbed and extruder. Default settings are as follows:
Preheat PLA: Nozzle:180°，Bed:70°
Preheat ABS：Nozzle:230°，Bed:110°
During heating process, please observe if the extruder and hotbed are heated to the preset
temperatures or not. Also note that after heating to the preset temperature, the temperature will not
rise and it maintains at the preset temperature.
You can change the preset temperature by entering LCD>Control>Temperature> Preheat PLA
Conf/Preheat ABS Conf. Choose Store Memory to save the current parameters in current directory.
5.2.3 Motor Direction
LCD>Prepare>Move Axis>Move Axis 10mm/ Move Axis 1mm/ Move Axis 0.1mm

www.geeetech.com
Shenzhen Getech Technology CO.LTD
If the homing and heating tests are normal, next you need to test the running of X, Y, Z axis and
extruder motor in Move Axis option. At the same time you need to observe if the running direction
of the motor is correct or not. For example, the extruder involves extrusion and withdrawing. If the
motor direction is opposite, the extruder can not feed normally.
X，Y axis can move at 10mm,1mm or 0.1mm.
Z axis and Extruder can only move at 1mm or 0.1mm.
For the printer, you need to check whether the extrusion is normal or not. Please set a reasonable
temperature depending on the melting point of filament, then test the feeding at 1mm or 0.1mm.
1）Choose CD>Control>Temperature>Nozzle to set extruder temperature.(generally it is the
melting point of the filament)
2）When the temperature of extruder reaches the melting point of the filament, begin the
extrusion at 1mm or 0.1mm. Check if the extrusion is fluent or not. If not, please refer to the
FAQ.

2.2.4 Unlocking motor
After unlocking motors, each axis can be moved by hand.
6. Hotbed Leveling
Before printing, please check whether the moving path of the extruder is parallel with the hotbed or
not, which is called leveling.
Coarse tuning
Adjust the trigger of the endstop of Z axis, and try your best to set the homing position of Z axis
right on the hotbed.

www.geeetech.com
Shenzhen Getech Technology CO.LTD
Fine tuning
1）Make a homing for the printer.
2）Unlock the motor, manually move the extruder to the three positions of the hotbed shown in the
picture. At this moment the nozzle tip is already very near to the hot bed because of previous coarse
tuning.
4. Put a piece of A4 paper between the extruder and hotbed. If there is a little bit friction when you
pull the paper back and forth, the distance is proper. Otherwise you need to adjust the screw in
this corner of the hotbed to slightly lift or lower the hotbed.
