Hi all!
First of all I'm new to all this stuff.
I would like to build a machine like this one:
I already have a Gecko drive G540. Can I run the Gecko stepper drive
with the Arduino board, and if, than witch one?
Thank you for an answer!

You could use a Gecko drive (any of them with a step/dir interface) but they would be overkill for this application. The NEMA-17 size motors he's using wouldn't require the power that the Gecko drives are capable of.
You would be better off with a RAMPS board (~$50) and the associated A4988 drivers (~$10/ea). That is what he's using in the video.
Thank you for your replay 
I already have NEMA-23 motors and my machine is bigger than this one.
Can you tell me if there is a ADURINO board that can run such combination ( NEMA-23, Gecko drive G540 )?
Thank you again!
Aleksander
