{{ _('E-Stop Settings') }}

Here you can change the command issued to your printer when you press the emergency stop button.

Usually this is M112. Only change if you know what you're doing.
Enabling this will attempt to automatically cycle the connection to the printer. This may cause the printer's control board to be reset and may help break out of blocking commands. Waits 3 seconds after the printer is "offline" before reconnecting.
A software emergency stop button is no substitute for a proper emergency stop button that physically cuts the power to the printer. How the printer responds to emergency stop commands, and connection cycling, will depend entirely on the printer's controller board and firmware. Never leave a printer unattended for extended periods of time.
