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.
