B-Robot DRV8825 Problem

B-Robot DRV8825 Problem
Hi,

I want to built a really stable version of the b-robot.
So I bought 0.9 degree steppers and want to get 1/32 steps....

But now I have a problem with my B-Robot and the drv8825 motor drivers.
I tried different drv8825 motor drivers but only one is working. The other drivers are spinning too slow it feels like one motor has double speed.
I can also switch the drv8825 from left to right and left or right motor is spinning way faster than the other side. Also I have trimmed the motor drivers and both are at 0.5 Volt. I have also already twist and shield nearly all cables to avoid interferences.

My setup consist of:

- 2 Wantai Motors (Nema17, 1.7A, 4200g.cm,0.9°,42BYGHM809)
- B-Robot ESP8266 Shield
- DRV8825 motor drivers
- Turnigy LI-PO 1000mAh battery (20-30c discharge)

So has somebody get the B-Robot working with DRV8825?
Is it also possible to get 1/32 steps not only 1/8 or 1/16??

Hope to solve my problem quick. Thank you in advance for your help.
