I’m having a bit of a problem with my Smoothieboard. While connected to Pronterface, Simplify3D, or Repetier Host if I warm the extruder and then click the off button the pin somehow gets written high and the temperature runs away. Same thing happens when I send m104 s0. I came in to a smoking hot end that had fried the thermistor as it passed through 600C. Any ideas on what would be causing the extruder heater output to go full power when S0 is written? I also have set the extruder max and min temps to 300 and 0 respectively. Thanks in advance.
