I'm sure this topic's been done to death but I still don't fully understand. How well do I need to understand? I need to understand well enough to know if my current or future project is okay. At one point I decided to forget about understanding and just put all grounds to one lug and let it go at that. And if that's true-- I'm done with this topic.
But it occurred to me that putting them all to one lug might not be just unnecessary. It might be wrong, contraindicated! So that gives me two more choices. I can keep asking questions until I understand or I can bring a pic of every system I ever wire and let people like Al tell me if it's ok. I'd rather understand. And the most important thing I need to understand is what constitutes a "foul". I'd also like to know if improper grounding is going to effect the performance of my CNC or simply interfere with my radio.
I need pictures to understand. I'll put some up later.
