Would be interesting to know what you did in the firmware to make that happen.

I didn't really do anything, I just downloaded the firmware that ward posted a long time ago on my big RUMBA thread, hooked up the end stops and it worked without jumpers.  So I don't know why others are saying that you need jumpers.  If you want, send me a PM with your email and I'll send you a copy of the firmware I use but its nothing special as far as I know.

This has made you the exception to the rule . Yours actually worked the way it's supposed to and by my count that is one out of 17 that I have encountered.  Like I said before, if I would just take the time I'm sure there's a logical answer.  In the meantime jumpers keep it simple.

btw - Solidoodle tends to way over do the steps for the extruder - try it around 210 or so to start with (105 for 4988 steppers x 2), then do the calibrations to verify it is feeding the correct amount and adjust accordingly.

If running Marlin as set for regular SD23or 4 you will need those jumpers shown in the above picture.  I have yet to get it to work properly through firmware changes alone.  I'm not in a position to view your file.  Smart phone isn't as smart as I'd like.

a couple observations on your firmware....

max extruder temp setting should be set to 295 to take over run into account - going over 300 will damage the thermistor.
#define HEATER_0_MAXTEMP 310     //{SD Patch}

your endstop settings:
// ENDSTOP SETTINGS:
// Sets direction of endstops when homing; 1=MAX, -1=MIN
#define X_HOME_DIR -1
#define Y_HOME_DIR -1
#define Z_HOME_DIR 1

mine are:
// ENDSTOP SETTINGS:
// Sets direction of endstops when homing; 1=MAX, -1=MIN
#define X_HOME_DIR 1
#define Y_HOME_DIR 1
#define Z_HOME_DIR -1

My printer is also an SD4 running on a Rumba and an E3D v6 hotend.
If you don't have one, I highly recommend an 8825 stepper driver for the extruder - much nicer than a 4988 with the E3D.

Thanks! That fixed my endstop issue! 
All my drivers are 8825.

Fan 0 is your G-code controlled fan or slider in RH.
Fan 1 is set in configuration.adv and turns on with movement or bed heat then stays on for a set time after things stop.  It's one of the best features ever.  It's amazing how loud all those fans are.  If you have trouble finding it let me know and I'll post a screenshot.

I tried moving the bed and turning on the bed heater, still no led for the Fan 1.
Endstops fixed sorta, the switches work now, but when I home, it only moves a little bit, I have to keep clicking the home button to keep it moving, and once it hits the endstop, it can't move away from it.

attached is my marlin file, if anyone smarter than I could look at it and see what I screwed up.
