15. How to Update Ender 3 firmware?
One of the important aspects that should do after assembling the Ender 3 is to update the firmware. May not be needed in day one, but possibility within week one.
There are two steps in updating the firmware:
- Installing a boot loader.
To install a bootloader so that future firmware update can be done via USB connection. This involves opening up the body and connecting an Arduino as an ISP. The steps may look overwhelming at the start but it is not very complicated.
2. Updating the firmware.
Install the latest version that has thermal runaway protection. It seems like Creality ships Ender 3 without the latest version of Marlin. (Marlin is an open-source firmware for the RepRap family of 3D printers. Ender series is one of them).
The firmware update process is nicely documented and there are many resources that you can follow. I started with this howchoo article, which was very helpful.
Below are the other videos that were resourceful:
The below two videos assumes that you have an Arduino that will help the installation of the bootloader.
The below video assumes that you have a USB ISP ASP Microcontroller Programmer device that helps to install the bootloader. Here are some options on Amazon.
I hope this helps!
