Milling-Machine

Frontend, Server, and Microcontroller code for a milling machine made for Lab IV at Texas Tech University.

Installing

The server and the front end are both handled by Node.JS - follow directions for installing from their site.

Depending on your choice of microcontroller either download and install Arduino or Energia. The code was written for a Tiva C Series Connected Launchpad but should work on other microcontrollers that are Arduino compatible. Edit the top of the code to match the pins on your microcontroller.

Usage

Go to the MillingInterface folder in terminal and run using

node index.js

Creating G-Code Files

Download and follow the directions from PCBGCode. EagleCAD is required for this script.
