1. Preface ----3D Printer User Guide I.1 Introduction The JGAURORA A-4 User Guide is designed for the A-4 users to start their printing journey with JGAURORA A-4. Even if you are familiar with earlier JGAURORA machines or 3D printing technology, we still recommend that you read through this guide, as there is lots of important information about the A-4 for you to get a better 3D experience. 1.2 Security matters 1) During printing, the temperature of nozzle part can be up to 250. To ensure safety, it is forbidden to touch the nozzle and build plate directly with hand. 2) during the running of the machine, it is forbidden to extend the hand into the machine to prevent the clip. 3) Always use the A-4 with a properly grounded outlet. Do not modify A-4 plug. 4) When the A-4 continuously work over 96 hours, it should be stop for 1-3 hours to restart. 5) Do not remove the models with force, and we recommend that you should wear protective glasses. 1.3 Filament requirements Do not abuse the filament. Please make sure you use the JGAURORA filament or the filament from the brands accepted by JGAURORA. If you won t use the A-4 in a long time, to avoid damp and affect print quality, you should remove the filament from the A-4 and sealed it. At the same time, to avoid filament knot, we should make its leading end fixed into the hole of filament tray. All polymers degrade with time. Do not unpack until filament is needed. Filament should be stored at room temperature:15-30 and in dry conditions. 1.4 Environmental requirements The printing temperature should between 5~40, humidity: 20%~50%, only in this range can the 3D printer work normally. 3

2) Choose the language you prefer(english as a example): ----3D Printer User Guide 9
3) Add printer ----3D Printer User Guide choose A-4, then press Add Printer 4) Load 3d file and slice it Load a 3d file of stl or obj, select the appropriate print quality, the lower right corner of the software shows "Slicing", that is to generate Gcode code. Choose the print quality you prefer 10
After slicing is completed, the lower right corner of the software shows "Save the file". ----3D Printer User Guide 5) Copy the G-code to the USB stick, insert it to USB port on the A-4 printer, and then select the file of gcode to print through touching screen. Note: How to operate the JGcreat software, pls refer to the file of Instructions of JGcreat in the USB stick. 11

4.2 Main menu introduction WIFI Extruder temp. USB Stick connected Firmware Info. Print menu Preheat menu Move menu Setting menu 4.3 Platform leveling Press the MOVE button, then press All, the extruder part moves to home. Press All 13
After back to home, move the extruder part through the moving shafts according to the directions as shown in the diagram, Prepare a piece of A4 paper as a reference, place it on the platform, move the nozzle to the A4 paper and make some withdrawaling of A4 paper, if the A4 paper is too loose to withdrawal, then clockwise the rotary nut; if the A4 paper is too tight, then anti-clockwise it. Step 1: Move to Right backward Step 2: Move to Left backward Step 3: Move to Left forward Step 4: Move to Right forward Note: Any question, pls refer to the video of Platfrom Leveling in SD card. 4.4 Filament loading Press the "Preheat" option, enter into "Preheat menu", select a corresponding material. This User Guide take PLA as an example. Select PLA(200) 14
In the process of preheating, firstly we open the top cover and install the filament tray to the stand, shown as pic: Load filament though the guide tube till stretch out from other end. Install the filament tray to the stand. Note: Load filament in the direction of clockwise. Press the pressing screw on the left side of nozzle, insert the straight filament with the other hand. When the temp. up to 200, click Move -- E+ button, till filament spill out. Filament spill out from the nozzle. Filament loading finished. 15
4.5 Filament replacement notes 1) In the process of model printing, when the filament is almost used up, pls follow the following steps for refueling: a: Click Pause on the interface of A-4, then the X axis will go back to the home. b: Click the "E-" button, and take off the tray after the filament is returned. c: Install the a new roll of filament, click the "E+" button, untill feeding finished. d: Click the BACK button, and enter the model print mode, and then click Start button to restore the printing. 2) When filament replacing, you are adviced to preheat the printer first, and then press the pressing screw with one hand, while push the filament down about 5-10CM with the other hand, then quickly pull it up. Pls do not pull it out savagely, otherwise, which will cause irreparable damage to the nozzle. 4.6 First printing 1) Model loading: Select and load the 3d file you want to print, or drag it directly into the software window. Click Open File 2) G-code save: After the 3d file slicing is finished, click Save to File button in the lower right corner to save, and then name it, copy it to the USB stick. Save the file 16
3) Insert the USB STICK into the USB port on the A-4, and then click "PRINT" on the "main menu", choose the 3d file of gcode. Click "START", the A-4 will preheat automatically, then the temp. of nozzle will reach the printing temperature you setted in the software, model printing begin until it is finished. Select the file you prefer to print. Click PRINT Note: when printing, if the first 1/2 layers can not be attached to the platform, please stop printing and re-leveling the gap between the platform and the nozzle. 17
5. Common problems and solutions ----3D Printer User Guide Item No. Problems description Reason Solution 1 Filament break at the extruder up end a. Forget to replace the filament which has used up b.

6. 3D printer maintenance ----3D Printer User Guide 1. Daily maintenance 1) Before using the machine to print, make sure that every safety protection measure are in good condition. 2) Regularly clean and maintain the equipment, try to clean the surface of the nozzle, hot bed, moving parts and other parts neatly, so as to prevent wear caused by excessive dust. 3) After each repair and maintenance, it is necessary to install the disassembled parts back to their original places, so as to avoid mechanical failures caused by missing and wrong loading. 2. Basic maintenance 1) Every day before opening the 3D printer, it is necessary to do some inspection carefully: whether the nozzle is blocked or damaged, the connection line of each part is normal, whether the guideway or optical axis is lack of oil, and whether the platform is calibrated and adjusted equally. when found rentate in nozzle, you need to immediately clean up; when parts or lines are damaged or aging, you should promptly replace them; add lubricating oil regularly to the rail or the optical axis; in the calibration process, if found the screw nut is loose, you should use six angle wrench, screwdriver, wrench and other tools to tighten it. 2) In the printing process of 3D printer,not only the design of each print model can not exceed the actual print range of the device, but also can not allow the machine to work in the too high temperature and too much load. Otherwise, it not only can not print the qualified product, but also damage the machine because the overload work. 3) In order to make you use print better, please pull out the print materials within the remaining extrusion head after finishing the printing work, and sealed well printed materials to prevent material becom damp and then break in the nozzle, finally cause nozzle clogging. 3. Transmission components maintenance When your machine is running, the noise becomes larger and the vibration becomes larger while moving. Then you need to clean the rail stains and add some lubricating oil to reduce the friction. specific Methods: first with a clean dust cloth to clean the grease or dust on moving parts, then drop 3-5ml (about 5-8 drops) lubricating oil, thirdly paint respectively that to the machine or rail axis, and move the moving parts to and fro, so that oil lubricate guide rail and polish rod. 19
