My wanhao duplcator I3 v2.1 shut down suddenly during a print, with some burnt smell, when I try to restart it the screen turn on and off in a short while. I checked inside the control board to see what is wrong and I found out the power supply plug on the control board melted and a pin also burnt. What should I do at this moment? replace the connector/board?

This is an ongoing problem with Wanhao. Mine actually caught on fire. The power requirements are more than what the connectors are rated for. Usually the problem starts with the heated bed connector since it draws the most power. If the printer is still under warranty, Wanhao should repair it at no charge. Consider yourself lucky that it wasn’t any worse.

You should get a replacement board, but the same thing is going to happen again. Look up Wanhao/Monoprice MOSFET heat bed fix. It’ll only cost you a couple bucks and you won’t have to worry about this again. And my hot bed actually hearts up slightly faster now.
