3D (Three-dimensional) printer control system based on ARM

Abstract

The invention provides a 3D (Three-dimensional) printer control system based on ARM. The 3D printer control system based on the ARM is characterized by comprising an upper computer design side and a core control panel integrated with an ARM microcontroller. The upper computer design side is used for carrying out initial configuration on the core control panel integrated with the ARM microcontroller through a firmware; a three-dimensional model of a printing material object is processed through a slice software so as to generate a G code command; and the G code command is stored in a data storage module. The core control panel integrated with the ARM microcontroller is used for reading the G code command in the data storage module, analyzing the G code command, and generating a corresponding control command for controlling a 3D printer to work, wherein the G code command comprises information of a motion trajectory planner and motion control. The 3D printer control system based on the ARM provided by the invention adopts an ARM microcontroller chip with a high performance, stores a design scheme in an SD (Secure Digital) card so as to realize high-accuracy 3D printing, and has highwork reliability and stability.

Description

technical field [0001] The invention relates to an ARM-based 3D printer control system, belonging to the technical field of 3D printing. Background technique [0002] 3D printing technology, also known as rapid prototyping technology, is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. Due to the limited complexity, complete digital control, and no need to open abrasive tools, 3D printers have great potential in production applications. [0003] The related technology provides a 3D printer control system, including a computer, that is, the main control board of the 3D printer is connected to a single computer, and the computer is used as the control system to send control commands to the main control board, and then the main control board is based on the control commands. Control the work of the 3D printer so that the 3D printer prints out corresponding objects. [0004...

AI Technical Summary

Problems solved by technology

[0004] However, in the current 3D printer control system, the printer must be connected to the PC at all times, which not only occupies the resources of the PC, but also needs to consider the instability of the USB connection during the printing process, so the real-time performance is poor

Moreover, the current desktop 3D printer control system mainly uses AVR series single-chip microcomputers as the core controller. This series of single-chip microcomputers has low operating frequency and few internal peripherals, resulting in slow data processing speed, complex circuits, difficult debugging and poor anti-interference ability of the system.
