M112 - Full Shutdown

safety Shut everything down and halt the machine.

Description

Used for immediate halt, M112 shuts down the machine, turns off all the steppers and heaters, and if possible, turns off the power supply. A reset is required to return to operational mode.

M112 is NOT a safety-rated “Emergency Stop” in the formal sense and is not guaranteed to meet the requirements of any safety category or required performance level (PLr). This is functionally a control stop. Machine builders should perform their own risk-assessment and implement suitable safety stop devices.

Notes

M112 is the fastest way to shut down the machine using a host, but it may need to wait for a space to open up in the command queue. Enable EMERGENCY_PARSER for an instantaneous M112 command.
