This, 110%. I had a client's Pinbot start smoking from a failed bridge while he and I were discussing leaving the machine off until I could come back with the parts to do the modification. I had used up the fuse holders I had doing my Space Shuttle and High Speed a few days before. It was a good thing we were standing right there when it happened, I managed to shut it off quick, but I still had to replace a bunch of wiring. He was about to put the machine out on location, I can't imagine how big a disaster that could have turned in to.
