6. Updating the Firmware
Over time new releases of the router firmware may become available. On the Ender 3 V2 this is a very simple process.
The new firmware is contained in a .bin file, check any release notes provided to see what changes have been made.
● Download the file to your computer and copy the file to the root directory of the Micro SD card.
● With the router turned off insert the micro SD card, then power on the router.
● The screen will remain blank while the firmware is updated (10-20 seconds) and then the normal boot process will take place.
At this point the update is complete!
You can verify the update version by checking the firmware version number on the Info screen.
The .bin file can be deleted from the SD card but the update will only occur once even if the file is still present on the SD card.
Some slicers offer an update the firmware option when the printer is connected via the USB cable, we strongly recommend using
the SD card method.
