Wireless CNC Plotter for PCB Using Android Application

Printed Circuit Board (PCB) making is very costly and tedious. It involves a chemical that is health hazardous and is not nature friendly. There are many constraints in making PCB at the developing stage during testing and debugging. Wireless Computer Numerical Control (CNC) plotter for PCB can be used to route the PCB wirelessly which can be sent using the computer or laptop. It also comes with a special feature of android app connectivity that can be used to track the work progress and even it can be used to send the data to the CNC plotter and you can use it on the go. The android application designed provides a simple interface so that the user can easily access the various options available. Memory is used to save the last state and the entire work can be recalled at any time. Further the material used is inexpensive, easily available, and is affordable. This tool can be used by an engineer to make the PCB for initial stage testing and debugging purpose. This method of CNC routing eliminates the harmful chemical used. The paper also represents the algorithm used by the controller and android application designed for the wireless CNC plotter for PCB.
