I posted some information about the E-Chain I desinged as a DIY project. I got a lot of requests for how I did it so I wrote it up step-by-step.
You can download it here

You can also download the Gcode for the project as well.
Here is a little video I made showing the dragon cable in action. This is actualy the third gen E-Chain I have developed, and holds up very well.
Feel free to post any questions about the dragon cable you may have. It should work for any CNC build. You can make the links out of any 1/8 material but I like hardboard cause its cheap and can be painted.
