I was making some 3d prints today to up my safety game to make sure all fumes and toxic stuff was properly dealt with.

I went to plug in a USB stick to my machine and it SPARKED. it shut off immediately.. I feel so useless I don't know how to fix this. Anytime I plug a USB stick into that drive the machine restarts, and gets stuck in a boot loop until you take the stick out.

I returned my fancy new laser engraver today, and now my only 3dprinter/laser engraver is an electrical hazard ;-; I need help
