- Requires 2 or more nozzles.

- The default hotend offsets are set with `HOTEND_OFFSET_[XYZ]`.
|
|
- Z hotend offset only available with `DUAL_X_CARRIAGE` or `SWITCHING_NOZZLE`.
|
|
- View current hotend offsets with [`M503`](/docs/gcode/M503.html).
|
|
- If `EEPROM_SETTINGS` is enabled, these offsets are saved with [`M500`](/docs/gcode/M500.html), loaded with [`M501`](/docs/gcode/M501.html), and reset with [`M502`](/docs/gcode/M502.html).
