Checks for unsafe or broken printer firmwares
The Firmware Check plugin tries to identify printers or rather printer firmware with known safety issues, such as disabled thermal runaway protection, or other kinds of severe issues, like known communication crippling bugs, and displays a warning box to logged in users on identification of such a firmware.
It was formerly called "Printer Safety Check" and used to be bundled with OctoPrint since version 1.3.7. It was unbundled in 1.4.1 and turned into an install dependency to allow for a separate release cycle. It is still considered a core plugin of OctoPrint, treated as if bundled and thus also active in safe mode.
The plugin is part of the core dependencies of OctoPrint 1.4.1+ and will be installed automatically alongside it.
In case you want to manually install it into an older version for whatever reason, install via the bundled Plugin Manager or manually using this URL:
