This is my very first post on this forum, hopefully you great people will sort my problem.
In my setup I have two nema 17 0.8A stepper motors, Pololu DRV8825 and ramps 1.4 on mega 2560. all the axis are working fine, but z axis is moving very slowly, is it because I have installed dual motors on single driver or there is some thing else that I am missing ?
Value on VRef is 0.40 V
