1. Preface
I.1 Introduction
The JGAURORA A8S User Guide was written to help new A8S users to start their printing journey with the
JGAURORA A8S. Even if you are familiar with earlier JGAURORA machines or experienced with 3D printing technology,
we still recommend that you read through this guide, that will help you have a better 3D printing experience.
1.2 Safety Advice
1) During printing, the temperature of the printing nozzle tip can heat up to 250℃. To avoid being burned, be
careful to avoid touching the nozzle while it is hot. The heated bed can also heat up to 100C, so please allow the bed
to cool down after printing, before you try to remove your completed prints.
2) While the printer is operating, there is a danger of hands or fingers being crushed by moving parts. To prevent
injury, please keep hands and long hair safely away from moving components, while the printer is operating.
3) Always use the A8S with a properly grounded outlet. Do not modify the A8S power plug.
Attention: Before power on, please check the input power is compatible with your local standard.( Method:
Observe the power switch at the hole of back base, if your local voltage is 230V, then adjust it to 230V, Similarly, if
the voltage is 115V, then adjust it to 115V.)
4) Please be careful when removing prints. The print bed is a glass sheet, so to avoid damage, please avoid using
excessive force. We recommend wearing protective glasses while removing prints. If you are using a spatula or
scraper to remove prints, please wear gloves to protect your hands from serious injury, and be careful not to damage
the print bed surface.
1.3 Filament requirements
Do not abuse the filament. Please make sure you use the JGAURORA filament or the filament from the brands
certified by JGAURORA. All polymers degrade with time. Do not unpack until filament is needed. Filament should be
stored at room temperature:15-30ºC, and in dry conditions.
PLA filament in particular can absorb moisture from the air, to become brittle and unsuitable for printing. If you
are not printing for extended periods of time, it is recommended to remove the filament and store it in an air-tight
box. Use the filament holes in the spool to hold the loose end of the filament, to prevent it coming loose and
becoming tangled.
1.4 Environmental requirements
The ambient temperature in the printing environment should be between 5 to 4ºC, with humidity between 20%
to 50%. Using the printer outside of these conditions may result in reduced or inconsistent printing quality.

1) Model loading: Select and load the 3d file you want to print, or drag it directly into the software window.
2) G-code save: After slicing of the 3d file is finished, click the “Save to File” button in the lower right corner to save
the file onto the USB stick, with an appropriate file name.
2) Insert the USB stick into the USB port on the A8S, and then click "PRINT" on the Main Menu , and then select the
3D Gcode file. Click "START" and the A8S will being to preheat the nozzle and printing platform. When the
temperature of then nozzle reaches the temperature set in the slicer software, the 3D printing of the model will
begin.
Click
“Open File”
Save the file

Note: When printing, if the first layer does not adhere to the platform, please stop printing and re-level
the printing platform and the nozzle, to set the correct gap.
4.6 Filament replacement notes
1) While printing a model, if the filament is close to running out, please follow these steps for reloading filament:
a: Click “PAUSE”at the printing menu, the X axis will then go to the home position.
b: Next click “OUT”to eject the filament out and remove the spool after the filament is ejected.
c: Install a new roll of filament, then click the “IN”icon until feeding is completed. Once the filament reaches the
nozzle, as small amount of plastic should start to extrude from the nozzle, in order to ensure the nozzle is primed for
printing. If this does not occur, extrude plastic manually until the nozzle is primed.
d: Click the “Back”button to enter into the model printing mode, then click the “RESUME”button to resume printing.
2) When replacing filament, please ensure the nozzle has been preheated to operating temperature first, before
performing the filament change. Please do not pull it out violently, otherwise it will cause severe damage to the
nozzle and extruder assembly.
Click “Print”
Select the file you
wish to print.

6. 3D printer maintenance
1. Daily maintenance
1) Before using the machine to print, make observe the safety recommendations.
2) Regularly clean and maintain the equipment. Clean the surface of the nozzle, print bed, moving parts and
other parts, to help prevent wear caused by excessive dust.
3) After each repair and maintenance, ensure all disassembled parts have been put back in their original place
to avoid mechanical failures that may be caused by missing parts or incorrect re-assembly.
2. Basic maintenance
1) Before operating the 3D printer, it is necessary to inspect the printer, and perform maintenance before use:
Inspect the nozzle for blockage or damage
Check the printing platform is calibrated and clean.
Check the printer is on a flat surface and is stable.
Check that screws and nuts are tight, and that no parts of the printer are loose or wobbly.
Check whether motion rails require cleaning or lubrication with oil.
When parts or lines are damaged or worn out, you should replace them before printing.
2) In the operation of the 3D printer, ensure not only that the design of each print model does not exceed the actual
printable volume of the device, but also do not allow the machine to work in too high a temperature or under too
much load. Otherwise, not only will it not print the object, but it can also damage the machine because of
overloaded work.
3) For best print results, please remove the filament remaining in the extrusion head after finishing printing.
Seal filament in air-tight containers to prevent material from absorbing moisture, which can cause filament to
become brittle and break during printing.
3. Maintenance of Moving Components
If you notice the printer has become noisy, or vibrates excessively, you may need to clean the rail rods and add some
lubricating oil to reduce friction.
To Clean and Lubricate: first, with a clean dust cloth, clean the grease or dust from the moving parts. Then apply
3-5ml (about 5-8 drops) lubricating oil along the motion rails. Brush the oil along the respective parts or rail axis, and
move the moving parts along the rails back and forth, in order to distribute oil within the bearings and to lubricate
the entire length of the guide rails and polished rods.
