Wi-Fi egg bot

Based on the M5stack core platform (ESP32), this project aims to provide a refresh to the original Egg Bot giving it the ability to load/slice/save/print files without the use of a PC.

Demo

Development work

Remaining things for a first release:

• WiFi setup - start firmware (or switch if unable to connect to a network) in AP mode. Allow changing the mode/wi-fi settings from the web client
• M5 UI - update M5 code to include UI to: start/pause/stop print, view progress and Wi-Fi settings (AP settings and/or IP in STA mode)
• OTA - easier firmware update (removing dependencies for platformio or other tools after the first flash)

Lower priority:

• Move image processing in web worker
• Make project compatible with generic ESP32 boards

Building

Web client (angular based)

Dependencies: node.js

cd eggduino-client
npm install 
npm run build

M5 code

Dependencies: PlatformIO

I personally use Visual Studio Code with the PlatformIO IDE extension.

platformio run                             - build code
platformio run --target upload             - upload code
platformio run --target uploadfs           - upload web client files
