Hi, @TechnewszoneAll you need is an image, then use Snapmakerjs to convert it to gresyscale then generate GCode to do laser engraving.

[About the Snapmaker Showcase category](http://forum.snapmaker.com/t/about-the-snapmaker-showcase-category/111/11) Check this out.

Tips:

1. Please be sure you choose greyscale mode. [https://manual.snapmaker.com/laser\_engraving/generate\_g-code\_using\_snapmakerjs.html](https://manual.snapmaker.com/laser_engraving/generate_g-code_using_snapmakerjs.html)
2. Follow this to focus laser [https://manual.snapmaker.com/laser\_engraving/set\_the\_laser\_power\_and\_choose\_a\_way\_to\_engrave.html](https://manual.snapmaker.com/laser_engraving/set_the_laser_power_and_choose_a_way_to_engrave.html)
3. Last but not least, try different wood

@poundteam We implement Dithering algorithm to generate Gcode. All you need is an image. These two images have been tested.
