Qt-based 3D printing control system and communication method thereof

Abstract

The invention discloses a Qt-based 3D printing control system and a communication method thereof. The Qt-based 3D printing control system comprises a controller, a field printing device and an upper computer. The field printing device comprises motion shafts, namely, servo motors. The method comprises the steps that a controller transmits a control signal to the servo motors to enable all the shafts to move according to a planned path; the upper computer communicates with the controller; tasks include monitoring motion information of the motion shafts and controlling and adjusting parameters in the printing process; controller communicates with the upper computer in a communication mode based on the Ethernet network, the IP address of the controller is preset, and whether communication succeeds or not is judged through a QT open instruction designated communication method and the opened port number; a query request is transmitted to a lower computer controller from upper computer software, and the controller returns corresponding data in a certain format according to the communication protocol. The Qt-based 3D printing control system is good in data processing capability, rich in on-chip resource and capable of detecting and controlling kinematic variables of a lower computer more and has the advantages of being high in reliability and good in stability.

Description

technical field [0001] The invention belongs to the technical field of 3D printing and communication, in particular to a Qt-based 3D printing control system and a communication method thereof. Background technique [0002] 3D printing technology is a technology that uses bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing based on digital model files. 3D printing technology is also called additive manufacturing technology. Compared with traditional "subtractive manufacturing" technologies such as machining, it is based on the principle of discrete / accumulation and realizes manufacturing through the gradual accumulation of materials. It uses the computer to cut the 3D model of the formed part into a series of "thin slices" of a certain thickness, and the 3D printing equipment manufactures each layer of "thin slices" from bottom to top, and finally superimposes to form a three-dimensional solid part. This manufacturing technolo...

Problems solved by technology

[0004] At present, some general-purpose 3D printing devices on the market have poor communication. In most cases, an LCD screen is used to control the operation of the entire lower computer. It is difficult to monitor all the control variables of the system, so that when some variables change during the printing process, it cannot be found in time. If no adjustment is made, it will cause printing errors and affect the quality of molded parts

Compared with the traditional open source ArduinoMega2560 3D printing control board, it also has its own upper computer control software, which can monitor some control quantities, but limited by the lower computer processor and on-chip resources, it can only use serial communication, and the data limited interactivity
