Sounds from z axis movement when updated firmware to Marlin K8200

Hi , I updated my firmware to “firmware_k8200_marlinv1”
everything seems to work but I get these noises when I use
Cura monitor 10 steps and 100 steps in z-direction.
See movie at:

What can be the cause of the sound from the z-axis movement ?
