CNC operational use case

Compiled and uploaded ESP3D to a BTT ESP32 module designed/dimensioned for my Octopus v1.1.

Firmware for BigTreeTech ESP32U ESP32E Module for Octopus (or SKR3/ SKR 3 EZ/ SKR 2)

Anyone got BigTreeTech BTT’s ESP32u ESP32e Wifi Module working with their Octopus or other BTT boards? Am trying to figure out whether the module comes with web server firmware already installed, or, if and how we should install. Not seeing much info on BIQU product page and BTT repo. Plugged ESP32U module into Octopus, then powered up the board. I see and join wifi network e.g. ESP_DC1234, but http and https requests are refused. Getting Ping responses though. Pinout picture in BIQU produ…

Did this back when I was transitioning my LR3 to Octopus v1.1.

You could probably take any ESP32 Node MCU and wire up to a SKR 1.2 Pro, or Octopus with the right Dupont wire connections, they’re mostly just using UART/Serial to communicate which just needs a few pins, e.g. TX, RX, RTS (Request To Send) and maybe DTR (Data Terminal Ready), I’m not sure exactly. For SKR 1.2 Pro, connecting an ESP8266 based ESP-01S would be more straight forward.
