Printer Safety Check

The Printer Safety Check plugin comes bundled with OctoPrint starting with version 1.3.7.

It tries to identify printers or rather printer firmwares with known safety issues, such as disabled thermal runaway protection, and displays a warning box to logged in users on such identification.

Currently the following firmwares produce this warning:

  • Anet A8 stock firmware

If you know of further printers/printer firmwares that need to be added here, please get in touch on the forum and provide their response to an M115.

Note

Feel free to disable the plugin in OctoPrint’s Plugin Manager if you feel like it is unnecessary. Be advised though that even if your printer might be running totally fine with a known unsafe configuration, that might change unexpectedly and with catastrophic results.
