Save values to Firmware EEprom

[wakeboy180]

I have the Prusa I3 and found that the number of steps for extruding the filament was way off. By default it is set to 760 and I found that my setting needs to be 90.5. The issue is every time I "Save To EEPROM" in the configuration tab in RepetierGEEEtech or Repetier-Host it says the value was saved but if I turn the system off it defaults back to the 760 on boot up.

How can I save this new stepper value to the EEprom?

Dear friend,

If you want to reset the step of Extruder, you need to modify the corresping parameters in the firmware. then reload it to the mother board。
（The last parameter：#define DEFAULT_AXIS_STEPS_PER_UNIT {}）

Best regards!

Is it possible to get a copy of the firmware for the ramps 1.4 or at least a copy of the configuration.h file that is pre-configured. I downloaded marlin from the ramps 1.4 wiki page but none of the settings are configured for the prusa I3.
