Marlin: DRV8825's

[WillShawx]

Description

When i attempt to use DRV8825's on Marlin 1.1.8, the motors vibrate and don't spin. However, using the exact same drivers on Repetier Firmware, i get no issues at all.

I change A4988 by DRV8825 on a Ramps board with Marlin 1.1.8. No problem but need to adjust current.

I’m using MKS GEN 1.4

Marlin 1.1.8 defaults to #define MINIMUM_STEPPER_PULSE 0 in Configuration_adv.h (this was changed in bugfix) DRV8825's require that you change it to #define MINIMUM_STEPPER_PULSE 2, you didn't supply configs as the issue template requested so I can only assume you haven't.

DRV8825's require that you change it to #define MINIMUM_STEPPER_PULSE 2

It may not matter on AVR, but it can't hurt.
