This is a professional and optimized firmware for Ender 3S1 3D printers. It is based upon original Marlin repository and has many improvements from the bugfix branch. You can get the latest version here: https://github.com/mriscoc/Ender3S1/releases/latest.
You can download the latest binaries from the assets at the bottom of the release page. To know if you have the last release go to the info page in the display of your printer and compare the release build date with the name of the binary file. The filename follows the convention:
Ender3S1-YYYYMMDD.bin
Where YYYYMMDD indicates the date of the build.
