So my printer was working just fine for maybe like 5 months with the board functioning perfectly. And recently it begun interrupting the print over and over again. After a few times of this, a part labeled S1G blew up. I think it was an overcurrent because my wiring was wrong as I only used one pair of screw terminals to draw in 12V for everything. So the screw terminal melted and the component blew up. After digging, it appears that it's a rectifier and honestly I don't know how to get a replacement for that. Preferably a THT for DIY repair. Any help would be appreciated in order to repair the board. Many thanks.
