M190 - Wait for Bed Temperature

thermal Wait for the bed to reach target temperature.
Related codes: M140

Description

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

Notes

This command may block the command queue. Enable EMERGENCY_PARSER so that hosts can break in using M108.

Use M140 to set the bed temperature and proceed without waiting.

Without any parameters M190 does nothing.
