ESP32Controller is an open source hardware controller for 3d printers, laser cutter/engraver and other CNC machines. There are currently 3 iterations of the board all based on either the ESP32 or ESP32-S2. The ESP32 is a dual core Xtensa LX6 with 34 GPIOs and the ESP32-S2 is a single core Xtensa LX7 with 43 GPIOs and built-in USB support.

Jul 30, 2023 · I am trying to create a device that can control 3D printers using serial communication. For this, the microcontroller I chose was the ESP32-CAM by AI Thinkers. I connected the ESP32-CAM to the WiFi and used Telegram, to communicate with the ESP.

This project helps beginners to quickly understand the basic usage of the Roller and Switch components and adds page jump function to replicate the UI interface of a 3D printer, which is very practical.

Most entry-level 3D printers require that the user copy the G-code file to a USB thumb drive or SD card, but this mod will let you use an ESP32 to transfer G-code to your 3D printer via Wi-Fi. This mod should work on most 3D printer models that have control boards with accessible UART (Universal Asynchronous Receiver/Transmitter) ports.

The E4 board is a minimal 3D printer control board based on the ESP32 microcontroller from ESPRESSIF, with built-in Wi-Fi and Bluetooth. The controller speed is up to 240MHz, 16M flash. Why do you need this board?

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.

Sep 20, 2021 · There is the timer-based standard method, but ESP32 has some HW-accelerated solutions, like:- PWM with modifiable frequency. Set it to 50%, and just adjust the frequency when needed. Also set a pulse counter on each output, so they can be HW-tracked, and set interrupt for them to adjust when needed.

Oct 14, 2022 · Wifi Module For 3D Printer(ESP32) This module is based on esp32, uses arduino for programming, and the firmware is open source. It realizes the core functions of wifi transfe

Apr 29, 2019 · Easier to add esp8266 wifi to an arduino board than to wire it as the direct controller and compile/port firmware with every change. Most people are moving on to 32 bit boards if they do any of this work.

If so, this new open source 3D printer control board based on the ESP32 may be worth checking out. The Espressif ESP32 module was originally developed for IoT applications, which is why it has built-in WiFi and Bluetooth capabilities.
