ELEGOO Centauri Carbon Review – An affordable CoreXY 3D printer suitable for beginners

ELEGOO Centauri Carbon CoreXY 3D printer review

CNXSoft: When ELEGOO offered us the Centauri Carbon CoreXY for review, Kajornsak was already busy with the review of the Saturn 4 Ultra 16K resin 3D printer, and I was busy (and still is) with other reviews. However, after learning it was suitable for beginners, I asked Kuljira, a high school student learning IT, whether she was interested in reviewing a 3D printer. She accepted and ELEGOO sent a sample for review. I did not provide much support apart from links to my review of the Creality Ender-3 S1 Pro 2-in-1 3D printer (in English) and Kajornsak’s review of the Twotrees SK1 CoreXY 3D printer (in Thai). Apart from that, I did not provide any support except once I told her she might need to add support after a print with spaghetti, and Suthinee helped her take pictures and handle writing a review in WordPress. The review below is a […]

ELEGOO Saturn 4 Ultra 16K Review – A resin 3D printer tested with CHITUBOX slicer and ChituManager software

ELEGOO Saturn 4 Ultra 16K 3D Printer Review Mercury 3.0 Plus

ELEGOO sent us the Saturn 4 Ultra 16K Resin 3D printer for review. As its name implies, the 3D printer features a 10-inch LCD with a resolution of up to 16K (14112×7936 pixels) to print sharper and more detailed workpieces. The printer also offers WiFi and Ethernet connectivity, and an automatic print base detection and leveling system to increase accuracy and reduce errors while printing. We were also provided with the ELEGOO Mercury Plus 3.0 wash and cure station for the review. It is designed to be easy to use, supports both water and alcohol washing, and is equipped with a 405nm UV light to increase strength and reduce the stickiness of the workpiece. Unboxing and Key features of the ELEGOO Saturn 4 Ultra 16K resin 3D printer Smart Tank Heating System The ELEGOO Saturn 4 Ultra 16K resin 3D printer features a “smart tank heating system” that enables high-quality […]

Roboreactor – A Web-based platform to design Raspberry Pi or Jetson-based robots from electronics to code and 3D files

Roboreactor Web based interface to design robots

Roboreactor is a web-based platform enabling engineers to build robotic and automation systems based on Raspberry Pi, NVIDIA Jetson, or other SBCs from a web browser including parts selection, code generation through visual programming, and generating URDF models from Onshape software. You can also create your robot with LLM if you wish. The first step is to create a project with your robot specifications and download and install the Genflow Mini image to your Raspberry Pi or NVIDIA Jetson SBC. Alternatively, you can install Gemini Mini middleware with a script on other SBCs, but we’re told the process takes up to 10 hours… At this point, you should be able to access data from sensors and other peripherals connected to your board, and you can also start working on the Python code using visual programming through the Roboreactor node generator without having to write code or understand low-level algorithms. Another […]

STM32H7-powered open-source hardware 3D printer mainboard supports up to 6 stepper drivers

SmartPrintCoreH7x Open Source 3D Printer Mainboard

Designed by Boltz R&D, the SmartPrintCoreH7x 3D printer mainboard is an open-source mainboard built around an STM32H7 microcontroller and designed to work with 3D printers from Creality, Anet, and Voron. It supports up to 6 stepper drivers (5 standard drivers plus 1 dedicated driver) and can be expanded further using the “SmartPrintCore Extravaganza” module for additional stepper drivers. Key features of this motherboard include a jumper-less setup, automatic power source switching, and support for both 12V and 24V power supplies. It uses high-efficiency TI buck converters to provide power for multiple fan and servo ports, and there is a dedicated power supply for peripherals, SBCs, and Wi-Fi modules. The board is equipped with a variety of connectors, including Molex, Ultra-Fit, Mini-Lock, and JST-GH for power, motors, and peripherals. SmartPrintCoreH7x specifications: MCU – STMicro STM32H723 Arm Cortex-M7 32-bit core @ 550 MHz with 1MB Flash, 564 KB RAM, FPU, DSP, Ethernet, USB […]

OpenFlexture Microscope is an open-source, 3D-printed microscope based on Raspberry Pi 4 SBC and Camera Module v2

The OpenFlexture Microscope is a DIY, open-source, 3D-printed microscope built around the Raspberry Pi 4, a Raspberry Pi Camera Module v2, and a choice of optics or various qualities up to lab-grade optics. It can be motorized using low-cost geared stepper motors and can achieve a resolution of up to around 100 nanometers I found out about the OpenFlexture Microscope in one of the sessions at the upcoming FOSDEM 2025 event whose description partially reads: The OpenFlexure Microscope is an open-source laboratory-grade digital robotic microscope. As a robotic microscope, it is able to automatically scan microscope slides creating, enormous multi-gigapixel digital representations of samples. The microscope is already undergoing evaluation for malaria and cancer diagnosis in Tanzania, Rwanda, and the Philippines. As an open project, our key goal is to support local manufacturing of microscopes in low-resource settings. [..] high-quality consistent documentation has enabled thousands of microscopes to be built […]
