6. Set engraving speed, engraving energy,and
engraving size
1. The recommended engraving speed is 1000, 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 "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.
Set the energy value. Improper
energy will affect the engraving effect
Enter the size of the graph you
want to engrave
The default engraving speed is

1. 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 "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 settings, click next to enter the settings of
engraving speed, engraving energy, and engraving size.
