Ender 3 V2 Fimware

Hello! This document is used as a repository for the custom firmware used on the PWB STEM printers.

Failure to use these EXACT FIRMWARE files attacked to this article will result in PERMANENT FAILURE

Explanation

Some explanation for the warning above. The attached firmware files on the left pane are custom built for the printers in this room. In the off-chance they become corrupted, or have software issues, use the files to re-flash the printers.

Therefore, we've decided to use mriscoc's Ender 3 V2 firmware. It's packed with features, and quality of life improvements.

The Anatomy of firmware names

The firmware files are named according to the printers features. There's an example below.
