<p>Possible? Yes. Advisable? Perhaps not. Since it is the power connection, I would be tempted to solder the cables directly to the board. If the board is found to work, I would then install an external MOSFET for the heated bed, to reduce the amount of current that the controller has to handle.</p>

<p>Recently my RAMPS power connector caught fire while heating the heated bed. I suspect this was a defect caused by the connector, and de-soldered/removed it as best I could. I'm  not an electrical engineer, so I'm looking for advice on whether It is possible to re-solder the power connectors directly onto the board, or I'm just risking another fire. Here are pictures of the top and bottom.</p>
