I have finished the hardware part for the two main axes of my DIY plotter project.
The main axis is based on a relatively old scanner.
The scanning head, with electronics removed and properly reinforced, is the support for the second axis. I have drilled two tracks in the scanner frame, along which the bolts connecting the two axes can move. The scanning surface of the scanner acts as the work plane for the plotter.
The second axis is the cartridge movement unit of a Xerox printer.
I’m working on the third axis, the pen up/down unit.
(Still waiting for the grblShield to power this thing and see if it works 
)
Andrea, your order went out a few days ago so you should receive it shortly. I added your project to the grblshield projects page:

Let us know how it goes.
Great!! I am eagerly awaiting the shield to bring this creature to life
It is awesome how a small component like the Arduino+grbl+grblShield unit can enable building a lot of interesting machines.
The range is very broad: mine is a moneyless-fantasy-and-fun project, while other people use it in serious setup: http://blog.makezine.com/archive/2011/09/grblshield-cnc-mill-conversion.html
