Creating my own Processing arc method

The Processing arc() command isn’t robust enough for my tastes so I wrote a new one that gives me more control over the things I care about. Along the way it lets me validate my arc code for the Makelangelo’s support of gcode commands G02 and G03. If people are learning Gcode then their arc() command would be helpful if it looked the same as a gcode command. Don’t you agree?



How to build an 2-axis Arduino CNC Gcode Interpreter

Computer model of where the 3-axis CNC router will move to cut the shape


3D printers, laser cutters, water jet cutters, robot arms, delta robots, stewart platforms, the Makelangelo: all of these are examples of computer numerical control (CNC) machines. CNC machines need to move accurately and on command. Stepper motors are a great way to move accurately – they move a predictable amount and then stay where you put them. To command the stepper motors we need a way to easily turn our human desires into machine instructions into stepper motor steps. In effect we need our robot brain to be an interpreter. I’m going to show you a simple interpreter written for Arduino that lets you move stepper motors for your robots.
