Values are stored in EEPROM and will be maintained upon power down of Arduino. But EEPROM works only if enabled in Marlin?
- M500 Store current settings in EEPROM for the next startup or M501.
- M501 Read all parameters from EEPROM. (Or, undo changes.)
- M502 Reset current settings to defaults, as set in Configurations.h. (Follow with M500 to reset the EEPROM too.)
- M503 Print the current settings – Not the settings stored in EEPROM.
