Hi

There are only a handful of settings that matter:

1) The display
2) The heater Kp, Ki, Kd numbers
3) The steps per mm on each axis
4) The thermistor types
5) End stops polarity
6) Home directions
7) The bed size
8) The speed and acceleration stuff
9) the temperature limits


Past that it's things like enable (or not) on the eeprom and bed leveling / probes. There is also some fluff like giving it a name. Get the first set of items above working and then add the other stuff a bit at a time. If you want to cut the list above in half and just do 1 through 6, the printer should work in that state. It won't be perfect, but it will boot and home.
