This is a case for the ESP32 Cam to hang inside of an Anycubic 4Max Pro.
The Firmware is taken from here: https://github.com/luc-github/ESP3D
From the GitHub site:
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.
