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. |
