This device is a protection for a 3D printer when a power outage occurs. If the power goes out, the printer will not be turned back on when the power comes back.
The scenario I have experienced is the following. I was printing an object using a laptop. While printing, the power went out. The Arduino stayed powered by the laptop. When the power came back, the extruder was turned back on but no filament was pushed in by the extruder. The result was a ruined J-Head. The filament was burned
