    Abstract: 隨著工廠自動化以及智慧製造的普及,雷射加工的需求與應用面也逐漸增加。雖現今大部分的加工機台皆可改裝為雷射加工機台,像是龍門式平台,機械手臂等等。但上述機台的馬達負載較大;而本次使用的H-bot機構,因其機構特色,可使得馬達平均負擔負載,也因此可以有較小體積。
    ;With the popularity of factory automation and smart manufacturing, the demand and application of laser processing are gradually increasing. Although most of today’s processing machines can be converted into laser processing machines, such as gantry platforms and robotic arms, however the motors of above processing machines have to bear a heavier motor load. The H-bot mechanism used in this study has the advantages of lightweight and lower motor load.
    In this research, the user interface can convert the input 2D bitmap into GCode and connect with the STM32 microcontroller. By using I/O and RS-485 control method, The STM32 can make the motor run at specified speed and step. STM32 also can control the laser driver by using PWM. Finally, achieve laser processing.
    By using X direction mode and multi-pixel mode, the result will have good grayscale performance and shorter processing time. With the design and improvement of the software, the final result can have better accuracy. Comparison with the previous research’s result, the result in this research achieve better performance on original image similarity.
