Topic: What settings are in SD(3) EEPROM?

I'm wondering if anyone can point me to a resource which lays out what settings are held in EEPROM, ideally the one in the Solidoodle 3?  I've seen the settings that can be edited in Repetier-Host, but am assuming there are others.  Given that EEPROM settings override firmware settings, I thought it would be useful to know what else - if anything - is set there.

Thanks in advance,
Matt

Re: What settings are in SD(3) EEPROM?

From EEPROM Retrieve Settings function in ConfigurationStore.cpp in Marlin:

  EEPROM_READ_VAR(i,axis_steps_per_unit);  
        EEPROM_READ_VAR(i,max_feedrate);  
        EEPROM_READ_VAR(i,max_acceleration_units_per_sq_second);
        EEPROM_READ_VAR(i,acceleration);
        EEPROM_READ_VAR(i,retract_acceleration);
        EEPROM_READ_VAR(i,minimumfeedrate);
        EEPROM_READ_VAR(i,mintravelfeedrate);
        EEPROM_READ_VAR(i,minsegmenttime);
        EEPROM_READ_VAR(i,max_xy_jerk);
        EEPROM_READ_VAR(i,max_z_jerk);
        EEPROM_READ_VAR(i,max_e_jerk);
        EEPROM_READ_VAR(i,add_homeing);
        #ifndef ULTIPANEL
        int plaPreheatHotendTemp, plaPreheatHPBTemp, plaPreheatFanSpeed;
        int absPreheatHotendTemp, absPreheatHPBTemp, absPreheatFanSpeed;
        #endif
        EEPROM_READ_VAR(i,plaPreheatHotendTemp);
        EEPROM_READ_VAR(i,plaPreheatHPBTemp);
        EEPROM_READ_VAR(i,plaPreheatFanSpeed);
        EEPROM_READ_VAR(i,absPreheatHotendTemp);
        EEPROM_READ_VAR(i,absPreheatHPBTemp);
        EEPROM_READ_VAR(i,absPreheatFanSpeed);
        #ifndef PIDTEMP
        float Kp,Ki,Kd;
        #endif
        EEPROM_READ_VAR(i,Kp);
        EEPROM_READ_VAR(i,Ki);
        EEPROM_READ_VAR(i,Kd);

        SERIAL_ECHO_START;
        SERIAL_ECHOLNPGM("Stored settings retreived:");

The default values are derived from the initial settings in firmware for all the above variables. The variable names more or less align with whats in Slic3r for the obvious stuff (and the Preheat stuff is for use with an LCD....)
