A4988 matching pulse (no replies)

I wanted to try marlin on my printer, but I'm encountering some issues with steppers and driver A4988.

I'm using this setting (as recommended for A4988):
#define DEFAULT_AXIS_STEPS_PER_UNIT    { 93, 93, 1097.5, 97 }

#define MINIMUM_STEPPER_DIR_DELAY 200
#define MINIMUM_STEPPER_PULSE 1
#define MAXIMUM_STEPPER_RATE 500000


For example, I have signal from original firmware which works fine, and this is how it looks for one step from encoder:

And here's from Marlin 2.0:

Here's also WFM files for this recorded signal.

Any idea which parameter to change in order to create the same step signal?

Thanks in advance.
