Comparing sprinter config file to repetier

I am running RAMPS 1.4 on Arduino mega 2560 on a Prusa, looking at trying out Repetier. So, the first thing I figure I need to do is set up a configuration.h file, translating the numbers from my Sprinter configuration file.

Now, some things are obvious. (RAMPS 1.4 is still 33, 1 is still a 100K thermistor).. I don't know what #include
#include "pins.h" do, I hope I can leave them alone.
Then the whole eeprom thing. Confusing, but I am still reading.
Instead of 1 line with x,y,z,extruder calibration figures, there is a line for each of xyz with more eeprom stuff and I assume the calibration factor buried in the extruder info. The default values look different enough, looks like I may have to redo calibration for the machine. (sprinter says Axis steps per unit, Repetier says mm, is a unit a mm?) Since I didn't do the calibration originally (shared machine) this could be interesting
Endstops. I go from a dozen lines and 3 things to either comment out to set to true or false to a bunch more, none of which appear to be commented to start out. (unless you can comment many lines at once.)

After all this whining, my question: Is there anyone out there who translated a sprinter configuration file to a repetier configuration file who would be willing to give a little hand holding to someone who understands the basics, but gets bogged down in firmware?

They are the same plus some more. Names may have changed.

It includes the board pinouts and activates the one selected, 33 = RAMPS 1.4 in your case. Thermistor type 1 is the same as in sprinter.

Here is a good doc if you haven't found it so far: [www.repetier.com]

Sprinter units are mm. So steps/acceleration are the same. Extruder stuff is seperated to allow multiple extruders.

The same as in sprinter, but it was split for each end stop, so you can use different types of end stops in one printer.

There is not really much to do. Get the steps per mm, thermistor, end stops and board id right and you are done for a first test and these are the same as in sprinter. The rest can be changed from Repetier-Host in the eeprom settings window if they don't match. If you have a special problem after that and can not track it down to a specific setting causing it, ask again.
