PandaZhu – ESP32 powered 3D Printer controller board supports Marlin 2.0 & ESP3D WebUI

PandaZhu ESP32 3D Printer controller board

Around two years ago, we noted beta Marlin 2.0 support for ESP32 and some initiatives to create ESP32 powered 3D printer controller boards with built-in WiFi connectivity. Now Marlin 2.0 firmware officially supports ESP32 boards such as FYSETC E4, E4d@BOX, or MRR ESPA. Another ESP32 based 3D printer controller board has now been brought to my attention. PandaZhu supports up to eight motor drivers, up to three heaters, up to three thermistors, one external LCD display, and on the software-side, the board is compatible with Marlin 2.0 as well as ESP3D WebUI. PandaZhu board’s specifications: Wireless module – ESP32-WROOM-32 based on Espressif ESP32 dual-core Xtensa processor @ 240MHz with 520 KB SRAM, plus 4MB flash Connectivity – 802.11b/g/n up to 150 Mbps, Bluetooth 4.2 3D printer peripherals Up to 8x motor drivers Up to 3x heaters Up to 3x thermistors with 30°C to 250°C range, BLTouch auto-leveling sensor with a […]

Teensy 4.1 Cortex-M7 Board Gets Marlin Firmware and OpenPnP Breakout Board

Teensy 4.0 and Teensy 4.1 are some of the most powerful microcontroller-class boards you’ll find on the market thanks to NXP i.MX RT1062 Arm Cortex-M7 crossover processor clocked at up to 600 MHz, and there won’t break the bank are PJRC sells those for $20 and up on their own store or Amazon. If you’re into 3D printers, CNC, or pick-and-place machines, you’ll be glad to learn Teensy 4.1 board is the first Arm Cortex-M7 board to support Marlin 2.0 firmware, and a person nicknamed CrazzyFrenchDud is developing PeeNaPle breakout board for Teensy 4.1 to work with OpenPnP open-source software. The initial commit to Marlin firmware was made on September 10 for both Teensy 4.0 and 4.1 boards, but the title was changed to Teensy 4.1 only since Teensy 4.0 is not supported at this time, and may not be suitable for many 3D printers due to a lack of […]

Marlin 2.0 Open Source 3D Printer Firmware Finally Released

Back in June, we wrote about Marlin 2.0 firmware supporting ESP32 3D printer board, but at the time the firmware was still in RC1 (Release Candidate) phase. I was informed Marlin 2.0 firmware had been in beta for several years now, but the good news is that Marlin 2.0.0 open-source 3D printer firmware has now been officially released. Some of Marlin 2.0.0 new features include: 32-bit support with several boards including Arduino DUE (SAM3X8E), Adafruit Grand Central (SAM5D), Smoothie / SBASE / EZBoard based on NXP LPC176x, SKR Mini powered by STM32, as well as ESP32 boards Some improvements were made to some AVR boards including Melzi (ATmega 1280), RAMPS (ATmega 2560), and RAMBo / miniRAMBo / Einsy RAMBo boards PlatformIO build environments for supported boards VSCode “Auto Build Marlin” extension for one-click build Power-Loss Recovery for SD print jobs Magnetic Parking Extruder support Magnetic Switching Toolhead and Toolchanger support […]

TH3D EZBoard Lite Board Upgrades Ender and Creality CR-10 3D Printers

The basic setup of Creality 3D’s very popular Ender and CR-10 series 3D printers now have a drop-in board upgrade that is poised to rival printers that cost many times more than the Creality models. The original board only utilizes the ATmega2560 microcontroller, the A4988 stepper motor drives, with those cheap Chinese capacitors. The board runs Marlin 1.x open source firmware. This setup is very close to the Arduino Mega 2560 and the RepRap RAMPS 1.4 board which are some of the most common and simplest board combinations in the world. The upgrade from TH3D, is the EZBoard Lite, makes some very important changes to the overall board ability, scalability and functionality. The physical process of upgrade is simple and easy. The outcome is an increase in speed and functionality that is comparable to 3D printers costing 5 to 10 times as much. Features Easy Drop-In Installation No Soldering No […]
