[ML-General] Weird Smell from Wanhao Duplicator i3 Control Box

[David Cantrell]

 You would have to double check the burned areas inside of the control box
for hints, but from personal experience, 3-D printers burning are usually
the heat bed connector on the motherboard over amping, shorting and
catching fire. For future reference, you can buy a cheap adapter card on
Amazon that has a MOSFET that allows the heat bed to pull power directly
from the power supply which prevents the over amp situation.
