|
title: Set Hotend PID
|
|
brief: Set PID values for a hotend.
|
|
author: thinkyhead
|
|
|
|
requires: PIDTEMP
|
|
group: thermal
|
|
|
|
codes: [ M301 ]
|
|
|
|
notes:
|
|
- Requires `PIDTEMP`.
|
|
- View current PID values with [`M503`](/docs/gcode/M503.html).
|
|
- If `EEPROM_SETTINGS` is enabled, all hotend 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).
