Design of simple 3D printer control system

Abstract

The invention relates to design of a simple 3D printer control system. The design of the simple 3D printer control system is characterized in that ATmega2560 is used as a main controller; computer slicing software is used for slicing a 3D model and generating a G code; the G code is transmitted to the main controller via a serial port; a three-axis motor driving module controls an extruder of the printer to carry out 3D printing; a fuzzy PID algorithm is used for accurately controlling the temperature; the three-axis motor is controlled by PWM technology; the test result shows that the temperature of an extrusion head is controlled to be 245 DEG C and the control accuracy is 1 DEG C after the fuzzy PID algorithm is used; the time for entering constant-temperature state is changed from about 250 seconds in the prior art into about 70 seconds; the three-dimensional printing constant-temperature control performance is improved; the phenomena that the printing material is broken and the thickness is not uniform in the printing process are reduced; the requirement on the printing quality is met; the simple 3D printer control system with low cost and low power consumption is achieved.

Description

technical field [0001] This application relates to an application field of 3D printing technology, in particular to the design of a 3D printer control system. Background technique [0002] Most of the current 3D printers have the problems of high price and high power consumption, and the time for the print head to enter the constant temperature state is relatively long, which makes the printing material prone to broken wires and uneven thickness during the printing process. Therefore, a design A 3D printer with low cost, low power consumption, high printing quality, and fast temperature control of the print head is necessary. Contents of the invention [0003] The main purpose of this application is to provide a simple 3D printer control system with low cost, low power consumption, fast and stable temperature control. [0004] In order to achieve the above purpose, the control system includes: the minimum system module of the main controller, the USB interface module, the...
