I have a few 3D Printers, a scratch CoreXY build, Tevo Tarantula, and PowerSpec Ultra (rebranded FlashForge Dreamer) I run prints unattended often. Overnight or leaving my house for errands. The only thing I do is regularly check termination points and board components to see if they are fine.

I wish I knew what was wrong with other people's configurations or the quality/settings of their hardware that causes these fires.

I blame kit providers racing to the bottom to throwing together low quality hardware and passing them off as solid workhorses. For my Tevo Trantula I replaced the screw down terminal block for one with higher amperage rating after noticing some slight melting on the housing, and spent a whole day doing PID tuning for the hot end and the heated bed.

There should also be a bigger disclaimer for kits to deter people who don't have decent knowledge in electronics to just go for complete printers or higher quality/proven kits.
