Reading about Ground Plane it’s get more confusing. So in my cnc control panel (about 20”x20”x 9”) I have the 4 stepper drivers, 3 PSU’s and a BOB along with ESS. If I get a piece of metal 3”3”x1/8” thick would that be considered a Ground Plane? If not, any suggestions?

Reading about Ground Plane it’s get more confusing.

Here is two definitive papers on grounding and bonding by Siemens.
I have used these methods over the years with no kind of problems experienced.
See the one on shield grounding that has changed when carrying out equi-potential bonding of the earth conductors.

What is everything mounted on, this is normally a Metal Panel and unpainted wherever anything is mounted this must be paint free

The Ground Bus is attached to the Ground Plane, (Ground Bus is where all Grounds connect Star Ground) so in your cabinet the Ground Plane is the metal panel that everything is mounted on

Outside the Cabinet the machine is the Ground Plane, the machine and the Cabinet are Grounded Bonded together from the Ground Bus to the Machine

So, the Ground Plane can be any part of the machine or cabinet if correctly wired

If not done this way nothing would be safe to use
