PRECAUTIONS

1. Avoid looking steadily at the laser, which may damage your eyes.
2. Avoid touching directly during the machine working.
3. Before engraving, put the honeycomb structure platform under the object.
4. Avoid combustible object or gas.
5. Keep it away from children or pregnant women.
6. Do Not take apart the laser without instructions.
7. Do Not use it on material that reflects the light.
8. Wear goggles while opening the acrylic cover.
9. Turn off the power when not use.

SAFETY GUIDELINES

Warning : Laser engraving machine cannot directly carve or cut material that reflects the light: may cause injury. The product has a high engraving speed and is not recommended for industrial cutting. And the laser head is a consumable. Do not operate the laser head directly with your hands. Please wear goggles. The laser diode is a sensitive component. please prevent static damage.

PART LIST

BEFORE USE

1. Remove the masking sticker attached on the metal housing and the acrylic cover.
2. Open the acrylic cover and take out the accessory packing box. (Figure A.02)
3. Cut the yellow ties fixed near the synchronous wheels of the X and Y axes. and check whether the laser head can move normally. (Figure A.03)
4. Cut the ties fixed on the honeycomb platform. take out it and check to ensure that there is nothing left in the machine. (Figure A.04)

FOCUS ADJUSTMENT

Focus adjustment before engraving:
When engraving. the focus needs to be on the surface of the object. The focusing distance of the laser lens is 50mm. The 50mm high cushion blocks (46mm + 2mm + 2 * l mm) can be used.

Focus adjustment before cutting:
During cutting. the focus needs to be in the middle of the fault of the engraved object. Therefore. according to different plate thickness. different cushion block combinations are used. Some­times. it is necessary to rotate the lifting Z-axis knob on the laser head counterclockwise for more fine adjustment.

Thickness of Plywood| Height of cushion block+ Rotation of 2-axis Knob
---|---
1mm

2mm 3mm

| 49mm (46mm + 2mm + l mm)+ half a turn

TEST BEFORE USE

1. Plug in to turn on the machine.

2. Test On Move:
   On the screen, click “Control”âž” “HHome”. After homing, click “Position” and click “X+” “Y-” to move. (Figure A.OS)

3. Test On Light Emission:
   Click “Adjustment” and choose”5%”. Wear goggles and observe whether the laser head emits blue ray. Then click “Off’ to turn off the laser. (Figure A.06)

4. Test On Engraving:
   Back up the data ofTF card to your computer first. Insert the TF card into the slot on the left side of the machine. Place Kraft paperboard at the appropriate position in the top left corner of the honeycomb platform. On the touch screen, click “Control” and “Home” to return to the initial position. Click “Engrave”, choose “TS3-Test. NC” file (Figure A.07), enter the interface below (Figure A.08). Click “Frame” to confirm the position. If the position is inaccurate, move the X / V axis and click “Position” and “Frame” to reset. Click “Carve” to engrave until the position is confirmed.

GRBL INTRODUCTION

Software Downloading
LaserGRBL is one of the most popular DIV laser engraving software. which can be downloaded in LaserGRBL website http://lasergrbl.com/download/ (The installation package is also available on the TF card from the manufacturer or USB flash disk).

Brief introduction:
LaserGRBL is easy to use. However. LaserGRBL only supports Windows system (Win XP/Win 7 / Win 8 / XP/Win l 0).
For Mac users. you can also choose LightBurn. which is also an impressive engraving software. but it’s not free. And this software also supports Windows system.

Note : The engraving machine needs to be connected with the computer during engraving. and the software of the engraving machine cannot be turned off.

Software Installation
Double click the software installation package to start the software installation and click “Next· until the installation is complete.

Language
Click “Language” on the menu at the top to select the language you need.

Load Engraving File
Click “File” and “Open File” in turn. as shown in figure 8.1. and then select the graph you want to engrave. LaserGRBL supports files in the formats of NC. BMP. JPG. PNG. etc.

1. Set picture parameters, engraving mode and engraving quality.
   LaserGRBL can adjust the sharpness. brightness. contrast. highlight and other properties of the target graph. We can preview window effect during adjustment. and adjust the effect to your satisfaction.

2. In the engraving mode. “Line-to-line Tracking” and “l Bit Shaking” can usually be chosen:”l Bit Shaking” is more suitable for carving grayscale graph. Please Choose “Vector Diagram” or “Center Line” if you need cutting.

3. Engraving quality essentially refers to the line width of laser scanning. This parameter mainly depends on the size of the laser spot of the engraving machine.
   Note : The recommended engraving quality range is 12-15. Different materials have different reactions to laser irradiation. so the specific value depends on the specific engraving material.

4. At the bottom of the preview window. the graph can also be rotated. mirrored. cut and so on. After completing the above settings. click next to enter the settings of engraving speed. engrav­ing energy, and engraving size.

Set engraving speed, engraving energy, and engraving size

1. The recommended engraving speed is l 000. which is considered to be a relative appropriate value after repeated experiments. Of course. you can increase or decrease this speed according to your preference. A faster engraving speed will save time but lead to the decline in the engrav­ing effect. Slower speed is the opposite.
2. In laser mode. there are two instructions: M3 and M4. M4 instruction is recommended for engraving in “l bit jitter” mode. and M3 instruction is recommended for other cases. If you have only M3 instruction on the laser. please check whether the laser mode is used in the GRBL configuration. Please refer to the official instructions of LaserGRBL for GRBL configuration.
3. Choice of engraving energy. Choose it according to different materials.
4. Finally. set the size and click the “Create” button to complete the setting of all engraving parameters.

Save GCODE file
Click “File” in the menu at the top of the software interface. enter the drop- down menu. and select “Save”. Copy the saved .nc file to the TF card and insert the TF card into the engraver to use the file to engrave your work. Use the “MKSLaserTool” software in TF to add preview codes to Geode files.

CONNECT PC

1. Connect the machine with the computer installed with LaserGRBL software with USB data cable.
2. Plug in the power.
3. Open LaserGRBL on the computer.
4. Select the specific port number and baud rate-115200 (Figure A.l OJ
5. Click the lightning sign. When the lightning sign changes to the red “X” and the direction sign is lit, it indicates that the connection is successful. (Figure A.l l)
   Generally, the COM port does not need to be selected manually, unless multiple serial port devices are connected to the computer, you can find the port of the machine in the device manager of the windows system (as shown in Figure A.09). A simpler way is to try the displayed port number one by one.

Note:
If you cannot find the correct port in the “Ports”, you may need to

• Method l : Click “Tools” in the menu to install CH340 driver (This function is not available in some software versions);
• Method 2 : Copy the “CH340ser. Exe” file in the TF Card (USB flash disk) to the computer and install it.

1. After the laser head has been used for a period of time, it is necessary to clean the lens of the light outlet under the laser head to ensure normal cutting ability
2. Wiping the lens must be done after the machine is powered off, otherwise the laser will hurt people
3. After wiping the lens, please dry it naturally for about 3-5 minutes and wait for the lens to dry before powering it on, otherwise the light will cause the lens to break
4. You can watch the video tutorial by scanning the QR code of the manual
