tag: m0105
title: Report Temperatures
brief: Send a temperature report to the host.
author: thinkyhead

group: thermal

codes: [ M105 ]
related: [ M155 ]

notes:
- Some hosts may hide the reply from `M105`.
- A better way for hosts to get regular temperature updates is to use [`M155`](/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.

- tag: T

  description: Hotend index
