Help needed DQ860MA

Hi all
Need help setting up DQ860MA Stepper Driver with Arduino UNO
on low RPM the vibrate and very noisy

I've connected them as attached below

here are my GRBL Settings

==================

$0 = 10 (Step pulse time, microseconds)
$1 = 255 (Step idle delay, milliseconds)
$2 = 0 (Step pulse invert, mask)
$3 = 4 (Step direction invert, mask)
$4 = 0 (Invert step enable pin, boolean)
$5 = 0 (Invert limit pins, boolean)
$6 = 0 (Invert probe pin, boolean)
$10 = 0 (Status report options, mask)
$11 = 0.010 (Junction deviation, millimeters)
$12 = 0.002 (Arc tolerance, millimeters)
$13 = 0 (Report in inches, boolean)
$20 = 0 (Soft limits enable, boolean)
$21 = 0 (Hard limits enable, boolean)
$22 = 0 (Homing cycle enable, boolean)
$23 = 0 (Homing direction invert, mask)
$24 = 25.000 (Homing locate feed rate, mm/min)
$25 = 500.000 (Homing search seek rate, mm/min)
$26 = 250 (Homing switch debounce delay, milliseconds)
$27 = 1.000 (Homing switch pull-off distance, millimeters)
$30 = 1000 (Maximum spindle speed, RPM)
$31 = 0 (Minimum spindle speed, RPM)
$32 = 0 (Laser-mode enable, boolean)
$100 = 640.000 (X-axis travel resolution, step/mm)
$101 = 640.000 (Y-axis travel resolution, step/mm)
$102 = 640.000 (Z-axis travel resolution, step/mm)
$110 = 2000.000 (X-axis maximum rate, mm/min)
$111 = 2000.000 (Y-axis maximum rate, mm/min)
$112 = 2000.000 (Z-axis maximum rate, mm/min)
$120 = 100.000 (X-axis acceleration, mm/sec^2)
$121 = 100.000 (Y-axis acceleration, mm/sec^2)
$122 = 100.000 (Z-axis acceleration, mm/sec^2)
$130 = 200.000 (X-axis maximum travel, millimeters)
$131 = 200.000 (Y-axis maximum travel, millimeters)
$132 = 200.000 (Z-axis maximum travel, millimeters)

any one ...
any idea ?

I'm afraid you forgot the core of the issue: your code. Without that it's rather hard to comment on where you may go wrong.
Expecting a reply within 3 hours is also a bit demanding for a free forum.

hi,
sure thing, attached
I use the Aspire 8.5 and the export as GRBL (in mm)
