{% hint style="success" %}
**📅Update: 2020/09/18**
{% endhint %}

## Description

Set the current for a stepper motor in milliamps units.

## Notes

* Requires one or more TMC stepper drivers.

## Usage

`M906` `[E<mA>]` `[I<index>]` `[T<index>]` `[X<mA>]` `[Y<mA>]` `[Z<mA>]`

### Parameters

* `[E<mA>]` Current for the E0 stepper
* `[I<index>]` (>=1.1.9) Index for dual steppers. Use I1 for X2, Y2, and/or Z2.
* `[T<index>]` (>=1.1.9) Index (tool) number for the E axis. If not specified, the E0 extruder.
* `[X<mA>]` Current for the X stepper
* `[Y<mA>]` Current for the Y stepper
* `[Z<mA>]` Current for the Z stepper

## Examples

Set the XYZ motor currents to 200mA

```
M906 X200 Y200 Z200
```

Set the E1 motor current to 10mA

```
M906 T1 E10
```

Set the X2 motor current to 5mA

```
M906 I1 X5
```
