The power plug to my RAMPS board started to come loose during a long print, resulting in a poor connection, heat and melting around one of the pins of the dual 12V connector. The socket on the board itself is OK. Anyone know where I can buy just the 4 pin (actually two 2-pin) connector by itself? Thanks.
The http://www.reprap.org/wiki/RAMPS_1.4#Bill_of_Materials shows the 4-pin version of the mating connector as WM7953. The Wiki has a link to the part from Digikey; that listing mentions it is Molex part number 39530-0004. 39530-0002 would be a two-contact version, but I can't speak to whether they are gangable or not for installation of two of them into the 4-pin board connector.
