So I just build my first printer a Prusa i3 and it's been working well for a day.
I started a new print when suddenly it stopped printing. Smelled something burning and saw smoke so I quickly unplugged everything. After checking all the cables it seems to come from the heatbed.
Everytime I plug in the heatbed cables, my power cable would get hot and the bed warms up. The led behind D8 stays red when I plug in the power. Everything else still works. I can still control the hotend temp. Bottom of the heatbed doesn't show any burn marks.
Should I get a new RAMPS board or just change the mosfet? How do i check if my Arduino is affected?
