Stepcraft 420 CNC build

I connected the Arduino Uno to the LPT port of the Stepcraft. The connections that I made:

Arduino	Stepcraft LPT port
GND	18
A0 (direction X)	2
A1 (direction Y)	4
A2 (direction Z)	6
A3 (step X)	3
A4 (step Y)	5
A5 (step Z)	7
D8 (X/Y/Z limit switch)	12

I use LibreCad to draw the parts that I want to make. It's a free and open source CAD application for Windows, Apple and Linux. Where CAD stands for Computer-Aided Design.

For creating the milling paths and controlling the Stepcraft I use the Estlcam software package that is created by Christian Knüll. Where CAM stands for Computer-Aided Manufacturing. The main advantage for me is the low level entry to milling software. And it uses a Arduino Uno for controlling the stepper motors. And don't be afraid, you don't have to program anything, just click and go.
