Thanks Innkeeper, I appreciate your comment.

Finally I start using Sanguino with Repetier Host and it works perfectly except for the fact that I can't move the axes in a negative position, but probably is my fault.

If I use positive coordinates it works like a charme!

Dear all, I finished today the mounting of a Mostly Printed Cnc.

I have no a Ramps but I have a Sanguino available....any suggestion for using this board? Someone of you already did?

Thanks a lot

Roberto
