I'm planning to modify my RepRap Discount Full Graphics lcd to include bed leveling

I’m planning to modify my RepRap Discount Full Graphics lcd to include bed leveling using MAX endstop (similar to that of ultimaker 2). Can anyone point me in the right direction on how to proceed? Cheers!

You’ll have to modify the firmware for this. The Um2 is adjusing the homing offset to build this feature. I can point you to the right code in the UM2 firmware if you want. (I made that modification for the UM2)

That is indeed a great feature of ultimaker 2 and it would be really helpful if you can tell me which file(s) to refer in the repository.

And yes I know a lot about your contributions in the 3d printing community

All the code that handles the magical bed setup is in here:

github.com

Ultimaker/Ultimaker2Marlin/blob/master/Marlin/UltiLCD2_menu_first_run.cpp

#include <avr/pgmspace.h>

#include "Configuration.h"
#ifdef ENABLE_ULTILCD2
#include "Marlin.h"
#include "cardreader.h"//This code uses the card.longFilename as buffer to store data, to save memory.
#include "temperature.h"
#include "ConfigurationStore.h"

#include "UltiLCD2_menu_print.h"
