## What it is
ESP3D is open-source firmware for ESP8266/ESP8285 and ESP32 boards that adds WiFi connectivity to 3D printers, CNC machines, and sand tables. It provides a web interface, file management, and serial-to-WiFi bridging so printers can be monitored and controlled remotely.

## Use cases
- add wifi to my 3d printer with an esp32
- control my marlin printer over the network
- send g-code to my cnc wirelessly
- monitor 3d printer remotely from browser
- replace usb cable with wifi module on printer
- upload files to printer sd card over wifi

## When to choose
- you have an ESP8266/ESP8285/ESP32 board and want wireless control of a 3D printer, CNC, or sand table
- you need a built-in web UI, file manager, and serial bridge without running a separate host
- you use Marlin, Repetier, GRBL, or Smoothieware firmware on the machine

## When to avoid
- you need OctoPrint-style plugin ecosystem and camera streaming - a Raspberry Pi host may fit better
- your printer controller has no free serial port for the ESP module
- you want a turnkey commercial product rather than firmware you compile and flash yourself

## Facets
- artifact type: application
- maturity: active
- function: embedded, http-server, file-upload, websocket, cli
- domain: iot, embedded-systems, hardware
- platform: iot, embedded, cross-platform
- tags: 3d-printer, cnc, marlin, repetier, grbl, smoothieware, wifi-bridge, sd-card, arduino, esp8285, automation, esp8266
