Short Step pulse can be problem too. My drv8825 work fine with ~1us Step, but according to specs it need 1.9us. So you can take twice function delay_1us
Code:
delay_1us();
delay_1us();
or
delayMicroseconds(2);

p.s. I was tried very short pulses on a4988. It can run with only 0.15 - 0.2us Step pulse.
