Mach3 will read the g-code and output signals to the machine that invoke the driver and motors. This application also serves as the tool to configure the connection to the actual CNC machine. They offer an evaluation version that allows you to run 500 lines of g-code. Mach3 is also created by the folks over at Artsoft. Mach3 is a perfect application for this part of the process. So now we need that g-code to be shoved into the machine so the object can be formed. The final software application is the one that this video is all about. It may cost a little, but it may be worth it. Another application that can be used is Laz圜AM by Artsoft. What's a layer, you ask? I will get into that in more detail later. It converts the DXF file to g-code and enables you to set specific parameters for each layer. My personal recommendation, because I'm cheap, is 'Ace Converter'. This DXF file needs to be converted to G-Code (a file that is understood by the last software application). So, you have a DXF file, say it's named citymodel.dxf. In this three program toolchain, an intermediary application is needed to link the CAD to the CAM. There are some applications that are relatively inexpensive, but did I mention I am poor? CAD, or Computer Aided (Assisted) Design and CAM, or Computer Assisted Manufacturing, can reside in a single application however, the cost can be astounding.

The latter of the software selections of only one application would be to purchase a CAD/CAM package. The more appropriate word would be 'poor'. The toolchain can contain as many as three software applications, or as few as one. In my explanation, I will discuss the individual software applications as the process is completed and I will get into more detail as I create the tutorials for each application. A software toolchain is a 'chain' of software that enables the completion of an entire process from design to implementation. What's a software toolchain anyhow? Well, my fine feathered machinist. Now we come to the software section of this tutorial series.
