What does EEPROM mean/do?

EEPROM stands for Electrically Erasable Programmable Read-Only Memory. It is a type of non-volatile memory used in electronic devices, including microcontrollers, computers, and other systems. Non-volatile memory means that the data stored in the memory is retained even when the power is turned off.

EEPROM serves as a storage medium for small amounts of data or settings that need to be preserved across power cycles. This memory can be read, written, and erased electrically, allowing for easy modification of the stored data.

In the context of 3D printers, EEPROM is used to store settings and parameters that are critical for the printer's operation. These settings may include calibration values, firmware settings, and other configuration data. EEPROM allows users to modify these settings without the need to recompile and upload new firmware to the printer every time a change is made. Instead, the printer's firmware can read the updated values from EEPROM during startup or when needed, and the user can adjust the settings using a control interface, such as a graphical display or a computer software.

Overall, EEPROM provides a convenient and flexible way to store and modify important configuration settings in electronic devices, including 3D printers.
