The speed, acceleration and dimensions of the print area are not recorded in EPROM

The problem is the following: change in the firmware of variables

#define X_MAX_LENGTH 105

#define Y_MAX_LENGTH 150

#define Z_MAX_LENGTH 30

#define MAX_ACCELERATION_UNITS_PER_SQ_SECOND_X 100

#define MAX_ACCELERATION_UNITS_PER_SQ_SECOND_Y 100

#define MAX_ACCELERATION_UNITS_PER_SQ_SECOND_Z 100

 And others in charge of movement

do not affect the operation of the device. Given that the values ​​that I entered using the alternative firmware before are clearly stored in the printer's memory.

At the same time, some variables work, for example, from the section // ################ Endstop configuration #####################

Tell me what you need to do to save these settings in EEPROM?

EEPROM_MODE = 1

(#define EEPROM_MODE 1)

Repetier

That is normal - it still uses values form first upload. Run
M502
M500

to reset eeprom to config values.

Thanks, everything worked
