I recently got hold of a nice WH20 and swapped the DMD out for a spare color one I had. Whilst doing this I noticed the original DMD had no ground braid attached. If I had left this alone what's havoc could this have caused? Luckily my color DMD had a ground braid supplied so I fitted this with the color DMD when I swapped them out. I'm not very savvy with machine electronics so I was just curious as to what could have gone wrong if this was left unchecked.
