if that was directed at me:

FysETC S6 v2.0 board with currently 4.24E on it. 
other data:

#define AXIS1_DRIVER_MODEL            TMC5160_VQUIET
#define AXIS1_DRIVER_MICROSTEPS       32 
#define AXIS1_DRIVER_MICROSTEPS_GOTO  16     
#define STEP_WAVE_FORM             PULSE

#define GUIDE_TIME_LIMIT                0
#define GUIDE_DISABLE_BACKLASH        OFF
#define SLEW_RATE_MEMORY              ON 
#define SLEW_RATE_BASE_DESIRED        5.0

the problem i am having sounds like what is happening here as well but i never thought about it maybe being microstep rates. For the rest check the older topic, my findings are in there
