Topic: hotend always on

I recently soldered headers to my sanguinololu in anticipation of adding a gcode controlled fan to my solidoodle. After a few bad prints caused by a badly seated power supply, I started up the solidoodle for another print. The temperature on the hotend shot up to about 230 degrees before I noticed. It seems okay so far (nothing melted off but I havent tried extruding yet) but I can't figure out what is causing the hotend to be stuck powered on. If I plug in either connection labeled "ET" on the bottom or "F" the temperature starts to rise. Did I short something while soldering? are one of the metal standoffs shorting something in the back of the board?

Re: hotend always on

need to find the instructions for doing this right as I see you didnt put the extra items on right side of board. search Solidoodle blog site for adding that fan it has pics etc. mean while unplug the fan and it should still work as b4 hopefully

Solidoodle 2 with Deluxe kit cover & glass bed with heater. and 2nd board SD2 used not 3rd and alum platform not installed yet still wood. also need cooling fan installed to board. use Repetier Host couple vers. Slic3r also have all free ware STL programs
