# \[Marlin] M105 - Report Temperatures

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

## Description

Request a temperature report to be sent to the host at some point in the future.

## Notes

* Some hosts may hide the reply from [`M105`](https://app.gitbook.com/docs/gcode/M105.html).
* A better way for hosts to get regular temperature updates is to use [`M155`](https://app.gitbook.com/docs/gcode/M155.html) (requires `AUTO_REPORT_TEMPERATURES` and `EXTENDED_CAPABILITIES_REPORT`). Hosts then no longer need to run an extra process or use up slots in the command buffer to receive temperatures.

## Usage

`M105` `[T<index>]`

### Parameters

* `[T<index>]` Hotend index

## Examples

Get a temperature report
