激光加工控制系统 可以读入plt文件，然后仿真，再通过并口 输出x y步进电机的驱动信号及开关光信号-Laser processing control system can read plt file, and then simulation, then through the parallel port output xy stepper motor drive signals and switch optical signals

利用MFC开发的用光驱开关控制程序，从而实现通过按钮控制光驱的开关。-MFC developers use the optical drive switch control procedures, in order to achieve the switch button to control the drive.

Use the API function to control the switch of the optical drive
