RAMPS with different motors. (1 reply)

Hi, guys. I'm currently making my first Reprap(prusa I3) And I can't find some information.
Please, help me to find out is it ok, to use Nema 17 stepper motors with different current(1,8A, 2A, 1.3A) in one reprap or i need completely simmilar stepper motors?

Thanks for your answer!
