Tested! Flash an Anet ET4 to Marlin 2+ firmware using ST-Link v2
183People have been clamoring for the Anet ET4 to have Marlin 2.0 since it arrived. Anet has listened and using an ST-Link V2, it is pretty easy. Anet shared files you can download them from the link below.

The original link from Anet appears to be dead.

There was also a desire for the firmware to be open sourced. Today, I can say it is here. Marlin 2.0+ has been released and is available for you to customize to your heart's content.
An awesome user Karl created a blog that showed how to recover or fix the ET4. I snagged a ST-Link and decided to give it a try and show you how it works.
