Requirements for grayscale engraving: 1. The source image is a grayscale image. 2. Select the line grayscale engraving mode on the software. 3. Turn down the power of the software. It is easy to directly engrave black with high power. 4. It is also related to the reaction of the engraving material itself after high-temperature carbonization. It is better to use wood carving to make it more obvious.
