# Select the radiobutton labeled "Ignore" under "Settings -> Serial Connection -> Behavior -> Error Handling -> What to do on firmware error".

# Reset/reboot your printer.
# When the printer has finished rebooting, Connect with Octoprint. It may take a moment, but that is to be expected.
# In the Terminal, issue a M502 command to factory reset the firmware to clear out any lingering data.
