You can set M111 1 which enables ECHO of commands send. This define specifies the position,

command. With checksum you know, how it looks from the sending string. With this define
uncommented, you will see the last command executed. To be more specific: It is written after
execution. This helps tracking errors, because there may be 8 or more commands in the queue
and it is elsewise difficult to know, what your reprap is currently doing.

Set the EEPROM_MODE to 0 if you always wan't to use the settings in this configuration file. If not,

it will detect a mismatch of the first byte and copys default values into EEPROM. If the first byte
matches, the stored values are used to overwrite the settings.

taken from the EEPROM.
