ESP3D
FW for ESP8266/ESP8285/ESP32 used with 3D printer
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/smoothie ware using GCODE) if the serial connection has a correct setup. I currently use it with my personal flavor of repetier for Due based boards. The web interface files are present in... -
