Hello! I’ve unboxed and put together my new A30 Pro, but I am completely new to 3D printing. I am having this issue where I cannot access the manual level bad adjustment menu and when I press Home for the Z axis, the head lowers itself and presses into the bed, making a loud grinding noise and leaving scratches across the mat. Can someone please help me?

Hi, you can adjust the four knobs under the hot bed to reduce the height of the hot bed.
