notes:
|
|
- This command (as well as [`M109`](/docs/gcode/M109.html) and [`M190`](/docs/gcode/M190.html)) can block new commands from the host. To break out of wait for temperature using [`M108`](/docs/gcode/M108.html) from the host, enable `EMERGENCY_PARSER`.
|
|
- Use [`M141`](/docs/gcode/M141.html) to set the chamber temperature and proceed without waiting.

This command optionally sets a new target chamber temperature and waits for the target temperature to be reached before proceeding. If the temperature is set with `S` then it waits *only when heating*.
