I have just discoverd that there is a bug in MKS sbase drivers drv8825
I was doing a clean install on it and got small layershifts on all axis after some help on Facebook I did get som help to sort it out.
I did have to enable in configuratiation_adv.h
#define MINIMUM_STEPPER_POST_DIR_DELAY 650
#define MINIMUM_STEPPER_PRE_DIR_DELAY 650
#define MINIMUM_STEPPER_PULSE 5
#define MAXIMUM_STEPPER_RATE 250000

and that sorted things out
please uppdate the example config in the repository

It is not obvious from the title, but this behavior is discussed in issue #11205 .

The settings listed here are a good workaround, but not a solution. There is a problem in Marlin causing it not to guarantee MINIMUM_STEPPER_PULSE. I am working on a fix, but it isn't quite ready to post yet. Maybe it will happen tonight.
