Rostock Mini Homing Fail

I am trying to commission my Rostock Mini but am having trouble with homing, the axes all slam into the endstops but fail to stop. I am running Marlin V1 for Kossel on a RAMPS 1.1 board and have the Signal and Ground or each axes MAX limit wired to the NC termanals of each microswitch. I have verified that endstoppullups are enabled in firmware and a quick continuity test shows that the switches are working. The only thing I do not know how to do is verify that the RAMPS board is reading the switches. Is there a way to monitor the switches in firmware?

Here is a video of my Rostock

Send gcode M119 to get the current endstop status.

The MAX endstops are undefined for RAMPS 1.1, so you'll need to edit pins.h before you can read them

Is this correct? I have never edited a pins.h file before

With all switches triggered this is what Repitier reported

> 8:12:55 PM: N157 G119 *3

Ignore my Repetier results above I get different values everytime I run G119 no matter what I do so clearly I am doing something wrong.

Thats M119, not G119.

I'm such an idiot, I had the X & Y Endstops mixed up. She is homing like a champ now!

Also such a rookie mistake on the M119.

End Stops not triggered

< 9:36:25 PM: z_min: TRIGGERED
< 9:36:25 PM: z_max: TRIGGERED

I feel kinda dumb

I thought I'd post this video of my first dry run after calibrating Z height and bed level.

Is that by chance raw output from the firmware to the host in response to the M119?

I believe so, this is what shows up in the log window of Repetier-Host.
