| Abstract: | Based on the background of South Additive Manufacturing Technology Limited Company. with SIEMENS S7-200 series PLC and MCGS as the core of software control, an automatic control system for 3D printing equipment of one type large metal component is provided. The PLC and MCGS touch screen of the system are communicated through MODBUS protocol, and the hardware communication network is built with industrial Ethernet, and the hardware of the wire feeding system is designed and the selection is completed. The wire feeding system realizes the closed loop control of the PID through the arc voltage feedback, which ensures the stability of the arc voltage in the 3D printing device, and controls the wire feeding speed by adjusting the print voltage accurately, thus optimizing the quality of the print work. |
