Re: [CAD_CAM_EDM_DRO] Control Software Vs Control Hardware

You are correct with your understanding.

Here is a controller that reads the G-code directly and controls the
machine;

The problem is that they are generally quite pricey. So most hobbyists use a
PC to do the same thing using CNCpro, EMC, or other. Some people have used
micro's to build their own g-code interpreter/controllers.

There is an industry standard for g-code, RS274, but every manufacturer has
some specifics for their own machine, and so there is no absolute standard.

Here's a starting point in terms of links..
