Overview

## Principle
3DPrinter and ESP32 are connected to the SD card through an analog switch. ESP32 controls the switching of the analog switch. Normally, 3DPrinter is connected to SDCard. When uploading files, ESP32 is connected to SDCard.

## The 3D printer
test uses elegoo neptune3pro, which only updates the file list when the SD card is inserted. The firmware needs to be modified and the file list is updated every time the file interface is opened (provided by Station B Light Manufacturing Modification method), the compiled firmware and screen firmware are shown in the attachment.

## Module firmware
* Option 1: ESP3D firmware
Use ESP3D project, just modify the pin definition
* Option 2: Firmware of this project
See attachment
