For a long while, I've been helping people diagnose problems with 3D printers and one of the things that stands out to me is how often people throw away bad prints while they're troubleshooting.

One of the first things I ask someone now is to give me their test prints for the last few changes they've made and what they changed, if they remember. Nine times out of ten, just looking at other factors, I've been able to pinpoint what's wrong.

Interestingly, this has also led me to a few "is it turned on" questions, the first of which is "when is the last time you tightened all the bolts that should be tight and loosened the bolts that should be loose?" The simple act of making sure tight things are square and tight has resolved many an unrelated problem because it makes you check so many different parts of the machine.

This also correlates with one of the takeaways from the old Computerworld column called Shark Tank. The most common aspect of the solution was to simply go and observe the failure, because so often it was an unaccounted for externality -- such as a cleaning crew unplugging something at 2AM when a system would "mysteriously" go down.
