Topic: Need help with Firmware side of Extruder Fan mod

Hi firmware gurus,

I'm not having much like dealing with arduino.
I have  a Solidoodle 3 with this board: http://www.soliforum.com/post/28760/#p28760
I had a friend solder up the mosfet and headers into the spots on the right side (not "fan" at the top) as described here: http://solidoodletips.wordpress.com/201 … ruder-fan/
I began following these instructions to enable the fan in my firmware and have completed up to step 13: http://www.soliforum.com/post/43170/#p43170
Now, when I went to enable the fan as mentioned here: ( http://solidoodletips.wordpress.com/201 … ruder-fan/ ) I found don't have a "Pins.h" tab on my arduino list as mentioned. I do have "SD2 pin map.h".

What have I done so terribly wrong?

Update:

Under Configuration_adv.h tab I do have this :

// Extruder cooling fans
// Configure fan pin outputs to automatically turn on/off when the associated
// extruder temperature is above/below EXTRUDER_AUTO_FAN_TEMPERATURE.
// Multiple extruders can be assigned to the same pin in which case
// the fan will turn on when any selected extruder is above the threshold.
#define EXTRUDER_0_AUTO_FAN_PIN   -1
#define EXTRUDER_1_AUTO_FAN_PIN   -1
#define EXTRUDER_2_AUTO_FAN_PIN   -1
#define EXTRUDER_AUTO_FAN_TEMPERATURE 50
#define EXTRUDER_AUTO_FAN_SPEED   255  // == full speed

Should  I change "#define EXTRUDER_0_AUTO_FAN_PIN   -1" to "4"?

Re: Need help with Firmware side of Extruder Fan mod

Where did you exactly get the firmware from? Can you provide a link? You should have pins.h... It might not show up in the arduino tabs, so you have to click on the small arrow after the tabs to get a dropdown menu with all the files. pins.h is with a small 'p', so it is ordered after all the filenames beginning with capitals. Alternatively, you can just navigate to the folder and open the file with any text editor. The options in Configuration_adv.h should not be relevant to your case.
