FDM型3D打印机电机控制系统的设计与优化

摘要

This paper focuses on the basic components of FDM 3D printer type motor control system design and description, which mainly includes the following components: micro-controller unit, three-way travel switch module, the two temperature sensing module, squeeze the machine and heating bed heating circuit module, four stepper motor drive module and basic communication get fast component. This document details the specific circuit of each module controls each module of the system implementation and basic principles, but also on the selection and some important parameters include summarized and computing devices. In the specific circuit design, the main consideration of the LPC1768 microcontroller circuit, stepper motor drive circuit and power supply circuit, finally, each module design also a certain amount of testing, concluded that the design of the motor control circuit composite technology claim.%文中主要对FDM型3D打印机电机控制系统的基本组成部分进行了设计与描述，这些部分主要包括以下几个部分：微控制器单元、三路行程开关模块、两路温度器的传感模块、挤出机和加热床加热电路模块、四路步进电机驱动模块和基本的通信模块组成的。同时，详细说明了每个模块控制系统的具体电路实现方式和基本原理，也对包括器件的选型和部分重要参数进行总结和计算。在具体电路设计方面，主要考虑了LPC1768微控制器电路、步进电机驱动电路和电源电路。最终，还对设计的各个模块进行一定量的测试，得出结论，所设计的电机控制电路符合技术要求。
