## Description

Use [`M92`](https://app.gitbook.com/docs/gcode/M092.html) to set the steps-per-unit for one or more axes. This setting affects how many steps will be done for each unit of movement. Units will be in steps/mm unless *inch* mode is set with [`G20`](https://app.gitbook.com/docs/gcode/G020.html) (which requires `INCH_MODE_SUPPORT`).

## Notes

* |Get the current steps-per-unit settings with [`M503`](https://app.gitbook.com/docs/gcode/M503.html).

  With `EEPROM_SETTINGS` enabled:
* This setting for all axes is saved with [`M500`](https://app.gitbook.com/docs/gcode/M500.html) and loaded with [`M501`](https://app.gitbook.com/docs/gcode/M501.html).
* [`M502`](https://app.gitbook.com/docs/gcode/M502.html) resets steps-per-unit for all axes to the values from `DEFAULT_AXIS_STEPS_PER_UNIT`.

## Usage

`M92` `[E<steps>]` `[T<index>]` `[X<steps>]` `[Y<steps>]` `[Z<steps>]`

### Parameters

* `[E<steps>]` E steps per unit
* `[T<index>]` Target extruder (Requires DISTINCT\_E\_FACTORS)
* `[X<steps>]` X steps per unit
* `[Y<steps>]` Y steps per unit
* `[Z<steps>]` Z steps per unit

## Examples
