  HEATER_2_PIN and FAN_PIN are identical for ramps 1.4. So if you now have a heater connected where previously the fan was, you need to connect fan to a adapter I guess. So now you need to set the fan pin to the pin of the adapter you use.

  I am using a KFB2.0 3D printer controller board which is ramps 1.4 I was having the same issue for where I had to have my extruder 2 hooked to my fan port to use the second extruder.  I have found out that if you change in pins.h for the ramps 1.3 where it says Heater_2_pin 9 to Heater_2_pin 7 then you can use the fan and the second heater they way it's suppose to work I was wondering if there is any way there can be a ramps 1.4 added to the pins.h with this change in it or atleast for the KFB2.0 board.

  Did you check MPX3 board? I think there is one more output for fan. Guess it could be exactly that layout.

  Good to Know thanks forgot what i did to fix my issue. but i did check mark another default in the configuration settings. now it seems to working like before think i used the heatbed output as the control point pin since no heat bed installed.  when i switch to the radds i have to fix several pins due to several fubar thermistor inputs so that may have contribute when i set up the 3 extruders on one heater and Thermistor defaulting to zero which is really the heat bed thermistor input renumbered   to zero :>)

  Multi extruder with shared heater can also share the same thermistor input, also it makes no difference if you use fake or real sensor for them.
