OctoPrint Firmware Updater
This plugin can be used to flash the firmware of your printer by selecting a file or an URL.
It can also check automatically for new firmwares by getting the printer's current firmware version and checking online for the latest one.
The automatic firmware update is done by detecting the current firmware version from the M115's response. This response string is parsed to identify the MACHINE_TYPE and the FIRMWARE_VERSION. This information is then sent to a web service which responds with information about the latests firmware available and the URL to download it, which is done automatically after the check.
The update check can be done automatically after connecting to the printer or manually from the plugin's dialog.

Configuration
In order to be able to flash firmwares, we need to install avrdude and then specify it's path. The path to avrdude can be set in the plugin's configuration dialog.
This can be usually found in /usr/bin/avrdude
In order to change the URL where the updates are checked you will need to edit OctoPrint's config.yaml.
