I spoke to an Epilog rep at a conference, he said the two most common
causes of fires are power supplies(they either overheat or fail and arc
electrically like the one you mention in dallas) and tray fires caused by
vector cutting over a tray full of discarded material. If you are cutting
patterns with lots of small detail, the little discards can pile up
quickly, and overshoot from the laser can set it on fire.
