Grinding noise on slow speed

Hi,
I'm testing a circle movement of my workbee that have dvr8825 stepper driver.
$100 $101 $102 should be 25 but I set to 250 so 1 step is 10mm movement.

My question is why does it make a grinding noise on slow movement? do I need to microstep?
I see the speed in the g code its F2.5

See the video below.

Yes... I would increase the micro stepping.
