This firmware allows not only to have a cheap bridge between Wifi and serial, but also to have a web UI to configure wifi, to monitor 3D printer and even control it, and to make things easy,
UI is fully customizable without reflashing FW.
Firmware should work with any 3D printer firmware (repetier/marlin/smoothieware using GCODE) if serial connection has a correct setup.
I currently use it with my personnal flavor of [repetier for Due based boards](https://github.com/luc-github/Repetier-Firmware-0.92).
The web interface files are present in data directory but UI has it's own repository [ESP3D-WEBUI](https://github.com/luc-github/ESP3D-WEBUI).
* Be aware ESP3D-WEBUI is for firmware 0.9.99 minimum - previous released version use tpl files which are no more used.
* Note for ESP8266 1MB flash : FW is now too big will all features you need to chose strip the FW and select only some features, also WebUI is now also too big for full multilanguage support to fit the 128K SPIFFS so please use pack with limited language (en +another) https://github.com/luc-github/ESP3D-WEBUI/tree/2.1/languages

## Features
* Serial/Wifi bridge using configurable port 8888
* Use GPIO2 to ground to reset all settings in hard way - 2-6 sec after boot / not before!! Set GPIO2 to ground before boot change boot mode and go to special boot that do not reach FW. Currently boot take 10 sec - giving 8 seconds to connect GPIO2 to GND and do a hard recovery for settings
* Complete configuration by web browser (Station or Access point) or by Serial/telnet commands
* Authentication (optional) for better security
* Update firmware by web browser
* Captive portal in Access point mode which redirect all unknow call to main page
* mDNS which allows to key the name defined in web browser and connect only with bonjour installed on computer
* SSDP, this feature is a discovery protocol, supported on Windows out of the box
* Fail safe mode (Access point)is enabled if cannot connect to defined station at boot.
* Embedded FS uploader and updater.
* OLED screen support
* Notifications using Line / Pushover / email
* The web ui add even more feature : https://github.com/luc-github/ESP3D-WEBUI/blob/2.1/README.md#features

## Installation
Feedback on 2.0 was : ESP3D being a library is not really useful and make setup more complex, so now we are back to simple application.
1. If you haven't already set up Arduino IDE for ESPs then do so for [ESP8266](https://github.com/esp8266/Arduino) or [ESP32 core version](https://github.com/espressif/arduino-esp32).
2. Download the [latest release](https://github.com/luc-github/ESP3D/releases/) and manually copy the libraries present in the `ESP3D-x.y.z/libraries` directory into your `Arduino/libraries` directory. (*no need if using platformIO*). *These versions are verified to work with ESP3D, any others (newer version) may cause untested behavior.*
- Use webserver support (recommended as stable), asyncwebserver support is no longer stable on ESP3D
- * arduinoWebSockets from @Links2004
Generic ones:
Specific for ESP32
* ESP32SSDP
If you want OLED support:
* oled-ssd1306 from @squix78
If you want DHT11/22 support:
* DHT_sensor_library_for_ESPx from @beegee-tokyo
3. Compile project esp3d.ino according target: ESP8266 board or ESP32 board, please review config.h to enable disable a feature, by default athentication is disabled and most others are enabled.
* for ESP8266 set CPU freq to 160MHz for better (https://github.com/luc-github/ESP3D/wiki/Install-Instructions)
4. Upload the data content on ESP3D file system
* Using SPIFFS uploader, this plugin and install instructions is available on each ESP core - please refere to it
or
* Using embedded uploader (you may need to format SPIFFS using : [ESP710]FORMAT on ESP8266 first)
if embedded uploader does not show up you can force it ti display using : http://your_IP_address?forcefallback=yes
