Hardware Control Circuit Design of FDM 3D Printer

Abstract

This paper designs the hardware circuit of desktop 3D printer. The STM32F103 are selected as the core processor due to its high-speed data processing capability and the rich peripheral interface resources. With the chip’s serial communication interface, provides a powerful and has a certain degree of expansion of the hardware platform for the 3D printing system, the use of stepper motor subdivision control driver chip A3979 control X, Y, Z three-axis operation, the theoretical analysis of the jitter algorithm applied to 3D printing, and strive to reasonable cost, simple structure, functional improvement on the basis of as much as possible to improve the efficiency of 3D printing and print output accuracy.
