M304 - Set bed PID parameters P I and D
M400 - Finish all moves
M500 - stores paramters in EEPROM
M501 - reads parameters from EEPROM (if you need reset them after you changed them temporarily).
M502 - reverts to the default "factory settings". You still need to store them in EEPROM afterwards if you want to.
