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.

  3. Press start

  4. Copy the .bin file to the root of the card (base folder)

  5. Ensure that the name of the file was not previously used to update the printer. If necessary, rename the file. (use gibberish, remember to keep the .bin extension)
  6. Turn off the printer, disconnect any USB cable and insert the Micro SD card.
  7. Turn on the printer, the upgrade firmware process will start automatically.
  8. The display will be blank until the upgrade is finished (about 15 seconds).
