Yeah but @tessa_scott, that easy fix can just be luck lol. Sometimes you chase a simple solder joint only to find the whole board is shot.

Sometimes even with a check, the tool can be in the wrong spot if your touch off plate is dirty. I mean, I've seen it save the machine but still wreck the part, which is a whole other kind of expensive. It's good advice, just not totally foolproof I guess.

Scale errors pop up everywhere once you start looking for them. I see it all the time with online furniture assembly guides where the parts don't line up. It's like a lack of double checking has become normal in a lot of places. Makes you wonder what else gets built wrong because someone didn't verify the numbers.
