Marlin 2.0 Open Source 3D Printer Firmware Finally Released

Marlin 2.0 Firmware Release

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 Gradient Mixing and Gradient Virtual Tools Automatic power supply control …

Pantahub Enables Seamless, Remote Linux Firmware Updates Over-the-Air

Pantahub

Let’s say you’re running Raspbian on your Raspberry Pi 4 board, but would like to check out the latest Ubuntu 19.10 for the board. What would you normally have to do? After downloading the firmware and turning off your Raspberry Pi 4, you’d normally need physical access to your Raspberry Pi 4 to remove the MicroSD card, insert it into your computer and start balenaEtcher or other utility to flash the image. Once it’s done remove the MicroSD card from your PC and insert it back into the Raspberry Pi SBC, before booting it up. That’s fine for experimentation, but time-consuming if you had to do this for multiple boards that may be placed in various locations. That’s where Pantacor’s PantaHub, PantaVisor, and PVR utility come in. Pantahub is a web dashboard used for registration, to monitor your devices, and documentation, Pantavisor is an Alpine Linux based  device init system that turns all the runtime into a set of container …

Olimex OSHW Allwinner S3 IP Camera Board in the Works – Feedback & Suggestions Welcomed

OSHW IP Camera Board

Allwinner S3 Arm Cortex-A7 processor is designed for dual-camera systems and embeds 128MB RAM. It looks to be an evolution of the older Allwinner V3s chip that came with 64MB RAM and is software-compatible with the older camera SoC. We reported about the new processor and an Allwinner S3 development board last year, but Olimex has started working on an open-source hardware IP camera board based on the processor and is asking for feedback from customers and the community at large. Preliminary specifications: SoC – Allwinner S3 Cortex-A7 @ 1.2GHz with 128MB DDR3 RAM at 1333 MHz Storage -MicroSD card slot, configuration EEPROM, optional NAND/eMMC/SPI Flash on socket Camera I/F MIPI camera connector with RPi pinout Parallel CSI camera connector Display – LCD connector for LCD-OLinuXino 4.3″ to 15.6″ displays Audio – Audio in and out via 3.5mm audio jacks Connectivity Fast Ethernet with PoE option WiFi / BT module with RTL8723BS Expansion – UEXT connector Misc – Buttons Power Supply …
