Ender3-S1-<date>.bin

 - Stock marlin configuration for Ender 3 S1
 - Adds G2 / G3 Arc support
 - Adds G10 / G11 Firmware based retraction (Use M207, M208, M209 to configure)
 - Adds M600 - Filament Change
 - Adds M603 - Set Filament Load / Unload length
 - Adds M701 - Load Filament
 - Adds M702 - Unload Filament
 - Enabled Advanced OK
 - Enabled CLASSIC_JERK
 - Enabled S_CURVE_ACCELERATION
 - Supports Meatpack

NOTE:
Pay attention to the two versions of the motherboard for the S1, one is using a SoC STM32F1 and the other using a STM32F4:

* Ender 3 S1 printers that come with a firmware version 1.x.x have the STM32F1 chip.
* Ender 3 S1 printers that come with a firmware version 3.x.x have the STM32F4 chip.
* Check the version number on the STM32Fx chip itself to confirm your hardware version.
* Installing 1.x.x stock firmware or a compiled one to the target STM32F1 on STM32F4 mainboards might brick them! And vice-versa.

Where to put the firmware file on the SDCard:
* STM32F1 board: Put the *.bin file into the root folder.
* STM32F4 board: Put the *.bin file into a folder named STM32F4_UPDATE.
