I have purchased a logitrol cnc unit that contained those drivers, and it always had 12v and it worked for years.

Hi

SOLVED
The problem with gecko logic power supply.
I tapped on my pc 5v power, instead of my 12v, and it works.
Is there any problem using my pc power supply 5v, to  my gecko drives logic power ?

Thats good to hear, there shouldnt be a problem but its hard to say without knowing the specifics of the actual boards you are using to supply the Step/Dir signals.
