Development of CNC Pen writer using Arduino Microcontroller

N. Ramu

In this paper explores the utilization of Arduino microcontroller over PLC controller for implementation ofCNC plottermachine.After learning through the various websites, this CNC plotter is fabricated using arduino microcontroller, two stepper motor ,one servomotor, interfacing relay cards and free open source software like linkscapeand processing software.The linkscapesoftware is used to generate the G code file for the given drawing and the processingsoftware is used for feeding generatedG CODE files are feed into the arduino controller which controls the outputdevices to reproduce the given drawing. This machinedraws the given sketch faster and more accurate than the humanbeing This machine can draw the images of letters, text, cartoons and shapes.
