How to Update the Firmware on the Ender 3 V2
Before my recent firmware update on my Ender 3 V2, my firmware was at least three versions behind the latest. This caused some issues when I updated my Cura slicer and set up OctoPrint on my Ender 3 V2. Creality updates its firmware to ensure that the printer works properly with third-party applications, among other things.
Not updating your firmware will eventually cause issues, so spend the five minutes running the update before your next print. It might just save a big print project from failure (which is the worst!).
Luckily, Creality has made it much easier to update the firmware on the V2 than it was to update the firmware on the original Ender 3.
How do I check my firmware version?
On your Ender 3 V2, use the selection knob to go Info. You'll see the firmware version your printer is currently running.
Here's the easiest way to update the firmware on the Ender 3 V2.
