Abstract: This report presents one of the application performed by Arduino Uno when sandwiched with Grbl shield which is a high performance open source CNC controller written in optimized C-language. Here in this paper a file with extension .jpeg or .png, or .pdf is imported in an open source Aspire software which converts it into .txt or .prt file. Vectors of the imported file is traced accordingly, followed by modelling and manufacturing procedures. Once the simulation of the manufacturing file is visualized in Aspire software then G-code file is generated using post processing operation, this G-code file is saved with .txt extension. The Gcode file is then browsed in Universal G-code sender software coupled to Grbl shield v0.9j and Arduino board through a laptop serial port, G-code visualizer option is available on Universal G-code sender software to visualize the manufacturing steps along with the simulation. In this way proprietory control of a controller is eliminated, and CNC machine is made user friendly.
