GRBL beginner’s guide
1. Software downloading
LaserGRBL is one of the most popular DIY 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).
2. Software installation
Double click the software installation package to start the software installation and click
“Next” until the installation is complete.
3. Language
Click “Language” on the menu at the top to select the language you need.
4. 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.
16
5. Set picture parameters, engraving mode, and engraving quality
1) LaserGRBL can adjust the sharpness, brightness, contrast, highlight and other
properties of the target graph. We can preview window affect during adjustment
and adjust the affect to your satisfaction.
2) In the engraving mode, “Line-to-line Tracking” and “1Bit Shaking” can usually be
chosen, “1Bit 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 setting, click next to enter the setting of
engraving speed, engraving energy, and engraving size.
6. Set engraving speed, engraving energy, and engraving size
1) The recommended engraving speed is 1 000, which is 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 instruction is recommended
for engraving in “1bit 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 GCODE 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 – 115 200 (Figure A.10).
5. Click the lightning sign. When the lightning sign changes to the red “X” and the
direction sign is lit, it indicated that the connection is successful (Figure A.11).
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.
The default engraving speed is 1000
and can be adjusted as required
Set the energy value. Improper energy
will affect the engraving effect
Enter the size of the graph you
want to engrave

NOTE: If you cannot find the correct port in the “Ports”, you may need to:
Method 1: Click “Tools” in the menu to install CH340 driver (The 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.

NOTE:
The energy value is set to 500, and the laser intensity accounts for 50 % of the power.
The energy value is set to 1000, and the proportion of laser intensity to power is 100 %.
The larger the energy, the faster the speed can be set.
The above parameters only for reference. Due to the different properties of the
materials, please adjust the parameter values according to the actual situations.
Machine testing guide
1. Turn on the machine and connect it to the computer.
2. Movement test:
Control the machine to move up down, left, and right on the software, check whether
the moving direction is correct (Figure A01), and check whether the moving distance is
correct (Figure A02).
3. Laser emission test:
The software imports the custom icon, click on the light (low light). Wear protective
glasses to observe whether the laser module emits blue light (Figure A03).
4. Test the files in the TF Card:
NOTE: Laser will generate heat and glare, which may cause harm. Please follow the
instructions to avoid injury.

Z-axis auto focusing configuration guide
Working principle:
The laser module lifter would move downward, once probe touching engraving surface,
Z-axis limit switch would be activated, and laser module would move upward to pre-set
lifting height. Once lifting height set in software, the machine would complete focusing
automatically.
When laser module moved 7 mm upward (lifting height set to 7 mm), the focal length
(distance between laser module to engraving surface) would be 50 mm.
