What is the problem?
Is there any way to stop a print straight away?
What did you already try to solve it?
Turned power off or waiting for the the web to stop the print.
Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware,
serial.log or output on terminal tab, ...)
It would be nice to have a input either a physical button or a button on the web gui to stop the print straight away.
