Can it’s right for my cnc ?
If not so Sujest me
Thanks
I trust you bro and
I am grateful to you for your all this halp
Once again from the heart big thank you

Your power supply is ok. I still recommend to connect only one motor. Try first the Y-axis like on my picture. Also remove the jumper you made in the green connector for the 12Volt. I also used only the two outer terminals.
Make sure that in the right GrblGru window axis positions are sent back when you move the Y-axis with the jog buttons.
When you turn on the 12 volts, the motor should be a little harder to turn. You have to adjust the current for the motor at the very small potentiometer on the small driver board.

I had try and grblgru send back axis position. But stapper can’t move
I had bought 3 year ago arduino uno and it’s ramps bord, stapper drivers, stapper motors, power supply
That time I just make a dry run and stapper are moving well
Then I Made mistake give a 12v power on uno and uno smoked and failed ramps bord and drivers are conected
So my question is in that accident drivers are failed? Or after long time I used that driver so it failed reson of moister ?
If drivers are failed so Sujest me which drivers now I order
Now 15 days ago I just bought mega or ramps bord
Or if other reasons of not working steeper so Gide me what to do.
Thank you and sorry for troubling you 
I assume that you can now move all axes, X,Y,Z,A and B, and that Mega-5X also sends corresponding axis positions in the right window. In parallel, the axes in the 3D model must also move on the screen. This means that Mega-5X works error-free.
So now you have only a hardware problem. I suspect that your drivers are defective. I don’t know if all of them are defective. You can try if maybe one driver is still ok.
I recommend you to order 4 new drivers in any case. They are not expensive. You have to buy drivers that can provide the current for your motors. I can’t help you there. Look on the Internet. There is a lot of information about drivers and motors. Also look again exactly how to set the current for the motors.
Wish you much success

Yes one driver was still unused. And I did it right now. And my stepper turned. My other stepper drivers failed.
Now I bay a new stapper drivers and then my machin is start
Thank you so much for all your help.
Your best wishes come true for me.
