Ping-pong method About multi-sided inspection

The standard specification for the ping-pong method is a one-sided inspection.

Multifaceted inspections are not supported.

Still, there is a need to inspect multiple surfaces.

Possible operational methods in this case are

KEEP INSPECTING ONLY SIDE A,

Then switch varieties.

CONTINUE TO INSPECT ONLY SIDE B.

This is a possible way to do this.

OF COURSE, IF YOU CONNECT A PLC FOR EXTERNAL CONTROL,

There are many more possible ways to do this.

But if you are trying to keep it low cost,

I think the above would be best.
