1. The software is not set properly; If you want to choose a engraving machine that supports DM/PL language, or choose a corresponding model of engraving machine, and if you want to turn off the tip compensation (small print below low-speed engraving 1CM can turn on the tip compensation, but the compensation value should be reasonable);

2. Serial port and parallel port are connected simultaneously; Or the same computer outputs to different devices;

3. The engraving file was interrupted before output;

4. When the parallel port is transmitting data, operate the keyboard;

5. The lettering software has been damaged, or the computer has virus infection;

6. There is electric welding nearby, or there is interference from power tools such as radio stations and machine tools. Communication using parallel ports is sensitive to external interference. If the external interference is strong, serial communication is recommended);

7. If an inappropriate regulated power supply is used, such as the relay regulated power supply of household appliances, strong interference will occur at the moment when the relay is turned on and off, resulting in communication data errors;
