So I have a 3D Printer (K280), and I needed to replace the fan. So I bought a spare that is compliant with the original specs. I stripped the wires and twisted them together (without covering them up first to see if they work first). A friend accidentally touched the fan while plugged in which caused the two exposed ends to touch and then sparks appeared where they touched and also appeared right where the fan wires connect to the board. Sadly the wires caught on fire and worked it’s way up.
Now I took a closer look at the board (MKS Base V1.5) and noticed this. If you look at the 3rd transistor, under it/on the board you can notice there is a darker color. I have to assume something got damaged here.
Do I need to replace the board?
Can I switch the extruder wires from the ports (green) E0 to E1 (They look to be identical so I don't see why not). It looks as if the three transistors are corresponding to each slot pair, and if that seems to be the case, I would think it is possible to move the extruder wires from E0 to E1 ports to avoid the potentially damaged transistor.
Are there any potential problems I should look for?
Thanks
