Help with DQ860MA Driver

HI All
I'll really appreciate your help

on acceleration and deceleration I have terrible noises ( something like the step motor goes step by step or under very heavy load )
on high RPM ( of the step motors ) they work pretty smooth ( jogging at 1000mm/s )

it's based on Arduino GRBL V1.1

I attach my motor connection schematics + Driver setting + GRBL Settings
