title: Home Offsets Here
|
|
brief: Set home offsets based on current position
|
|
author: thinkyhead

requires: HAS_HOME_OFFSET

|
group: motion

|
codes: [ M428 ]

|
notes: |
|
|
- Only the Z offset can be altered on `DELTA`.
|
|
- This G-code can be disabled with `NO_WORKSPACE_OFFSETS` to optimize movement.
|
|
- Changing the home offsets will not invalidate bed leveling or other saved data.
|
|
- If `EEPROM_SETTINGS` is enabled, the home offsets are saved with [`M500`](/docs/gcode/M500.html), loaded with [`M501`](/docs/gcode/M501.html), and reset with [`M502`](/docs/gcode/M502.html).
|
|
- Use [`M206`](/docs/gcode/M206.html) to set the home offsets directly.

|
pre: What was X=10 becomes X=0. So the X home offset becomes -10.

code:

- G1 X10

Use [`M428`](/docs/gcode/M428.html) to set a persistent offset to the native home position and coordinate space by assigning the current position as the native home position. See the example below.
|
|
|
|
- The current position must be within 2cm from 0 or an endstop.
|
|
- The current position is set to the native home position.
|
|
- Any previous position shift from [`G92`](/docs/gcode/G092.html) is cleared.
|
|
- The home offset is persistent — added to the current position until changed.
|
|
- Some uses include fine adjustment of Z position (without moving endstops) and shifting the coordinate space to print on a different part of the bed.
