The microcontroller can store settings to EEPROM

to use the fuction set in configuration.h
#define USE_EEPROM_SETTINGS --> Save and recall Settings aktive
#define PRINT_EEPROM_SETTING --> Print settings to UART

Commands:
M500 - stores paramters in EEPROM
M501 - reads parameters from EEPROM
M502 - reverts to the default
M503 - Print Settings

   - Corrected distance calculation. (thanks jv4779)
   - MAX Feed Rate for Z-Axis reduced to 2 mm/s some Printers had problems with 4 mm/s

+ - M502 - reverts to the default "factory settings". You still need to store them in EEPROM afterwards if you want to.
