I'm back at it finally. I put together a board to manage the heater connections and the power for them. It will also provide power to the Arduino Mega 2650. I have been using fritzing http://fritzing.org/ to manage my connections since I am wiring up the equivalent of a RAMPS board, utilizing the old Reprap 2.1 stepper controllers and the one pololu driver that I have been using for the extruder stepper.
