RAMPS 1.4 stepper driver failure? (no replies)

Hi All, I'm new here, my name is mike and about 6 months ago I bought an Anet A6.

Because this was not the quality printer I wanted, I made some pretty big modifications:

- Added aluminum frame based on the Anet AM8 (https://www.thingiverse.com/thing:2263216)
- Added Bowden setup with original E3D V6

Since the mainboard of Anet is also pretty crappy, I wanted to change this to RAMPS 1.4 (especially because you can change the current of the stepper drivers)

So yesterday i tried connecting everything to the ramps board to test 1 driver (DRV8825).

What happens now is i power the RAMPS board and connect to it through serial connection at 250000 BAUD.

After this i send "G1 X30 F3000" and i hear the stepper energizing (very soft humming) and it looks like it's trying to move.

Then after about 3 seconds the stepper is not energized anymore and the led on the RAMPS board (close to mosfets) starts blinking really rapidly.

The only way to reset the board is to totally cut the power (Also USB to RAMPS) and restart the system, it also doesn't respond to serial when it is in this "panic" state. (Also the reset button on the RAMPS doesn't do anything) the LED keeps blinking.

I couldn't find people with similar problems, but it might be that you have an idea what could be the problem?

I'm running on 1/32 microstepping (All three jumpers connected). and the Vref is set to 0.7 volts.

Thanks :)
