title: Set Chamber PID
brief: Set PID values for the chamber
author: classicrocker883

requires: PIDTEMPCHAMBER
group: thermal
eeprom: true

codes: [ M309 ]

notes:
- Requires `PIDTEMPCHAMBER`.
- View current bed PID values with [`M503`](/docs/gcode/M503.html)
- If `EEPROM_SETTINGS` is enabled, bed PID values are saved with [`M500`](/docs/gcode/M500.html), loaded with [`M501`](/docs/gcode/M501.html), and reset with [`M502`](/docs/gcode/M502.html)

parameters:

- tag: P
  optional: true

  values:
  - tag: value
    type: float

- tag: I
