Re: Driver Boards

The g-code interpreter is run on the arduino and the shield has the stepper controllers all built in. So, the complete system is the arduino, shield, 3 stepper motors and power supply. You just send the gcode over the serial connection through USB.

Re: Driver Boards

One newer board on the scene is a grblShield. It was featured on make.com in an article. I actually bought one but have not had the chance to play with it yet.

It is a basic shield for Arduino that has 3 stepper controllers on it. There is a video on http://dank.bengler.no/

Runs a subset of G-code.

Re: Anyone thought of this?

One advantage I see of building a 4x2 rather than a 2x4 is you don't have that much to convert if you want to go to 4x4 or 4x8 at a later date.

If it is not slated for expansion, you just end up with a longer and heavier gantry.
