[edit] Project Goal
The goal of our project is to create a cheep CNC router. The lowest price for a normal CNC Router is in the thousands of dollars. Once we complete our project we will have the instructions for how to create a CNC Router for about $500 and will make the code open source so that others hobbyists can make their own CNC router.
[edit] Design Specifications
The interface of the software will be relatively simple. The above screen shot is from the software that will convert the three dimensional CAD file into G-Code, which is the instruction set which is read by the CNC Router. The window shown above allows you to change properties of individual layers. This will need to be done depending on the material that is being used.
 Individual Layer Properties |
 Automatic Mode |
 Manual Mode |
The two screen shots above are from the Communication program on the computer. With this software you can load the G-Code file that was created by the converting software. This will be the automatic method for controlling the router. If the router needs to be controlled manually there will be a manual tab which will allow you to move the router freely.
This is a mock up rendering of what the final product will be similar to.
The diagram shown above is the general overview of our system. On the computer we will design two pieces of software. The first will convert the three dimensional CAD file into G-code. The G-code is a language made up of instructions that control the router. These instructions will be loaded into the communication program which will send instructions at request of the ATMega 328 microcontroller. This controller will be connected to the limit switches, the drill relay sThe diagram shown above is the general overview of our system. On the computer we will design two pieces of software.
