Thank you man

Nothing happened, always the same...

I will try to solder... Yes, I reflashed firmware many times

Can I have This firmware too?

I think that the board is defected, how Can I get another One ?

Yes... In X,Y slots Z motors works fine... Separatly but in both direction

If I remove the rods, motors run at the same way in one direction. With another driver nothing happen... It's the same thing

All wires are right, and motors are well because they run, but only in one direction. The electronic part is right, I tried to change some parameters on the firmware and it seems like there is a block with the rising movement of z Axis.
