Did this sound come out when he was homing, or was it made while he was working?
I remember in a private chat with you, you said that your homing was normal and didn’t make a sound.

If homing is good, then it may be that the software is not set up correctly and you let the z-axis go to an incorrect place. Note that the z-axis is 0 after the reset and the downward movement is negative.
