not sure what’s going on: my taz worked for all of 3 prints before the hotend began to stop heating up, at all.

if i plug the power resistor into where the bed is usually connected, it’ll begin to heat up. i even tried the following change in the firmware, around line 1330 in pins.h:  
//edited here to make heater on extruder connect to heater 1 port instead  
#define HEATER\_0\_PIN 7  
//was 9  
#define TEMP\_0\_PIN 0

#define HEATER\_1\_PIN 9  
//was 7  
#define TEMP\_1\_PIN 1

am i missing something, or did i just buy a very expensive paperweight?
