DRV8825 driver modules often use 0.05 ohm sense resistors instead of 0.1 ohm. So try turning the pots down to 0.8V.
I changed the voltage only for 1 driver to 0.6V, the rest I can;t seem to change the value. I turned the pot 360 degrees 10 times, both sides and measured each step, but it goes only from 1.6 to 3 V.
Does this mean the driver it's fried, or maybe the pot is damaged from the extreme heat on the previous tests ?
