I've had my printer for over a year and the other day thermal runaway tripped on the heated bed. I took a look around and saw my connector had melted down (Picture).

Is it possible to alter pins.h of Marlin to use a spare pin that to trigger a DC SSR with a heatsink (Link) connected to a typical PCB heater? Or would it be better to replace the whole ramps board?

Thanks in Advance

... yes, you can change pin definition -- look into the file "pins.h"

I've driven one of my heated beds with an AC-SSR and power from a 12V transformer (what gives rougly 16VAC) without problems ...
