Nema 17 stepper motor problem, how can I solve it?

Hello guys, I finally get done my Laser Engraver with Arduino, it's actually a combination of 3 projects from here, and now, at the end, my motors does not work...Here you can find the motor I use: connect them on a cnc shield with A4988 drivers, I use GRBL as a firmwale and the program for engraving I don't think they matter, because I use 3 of them with no results.P.S.: the Laser is working, the M03 and M05 functions works great, but the motors not a step...Thank you and I accept any speculations, I was thinking that the current from the driver was not enough, but after a research I found that isn't true ( I think ).
