Ender 3 Pro 3D printer in late 2020 – Build and first prints

Ender 3 Pro review 2020

Karl here. How does the Ender 3 Pro 3D printer stand up in late 2020? The short answer is pretty well. With just a few minor gripes it is a solid printer. According to All3dp the Ender 3 Pro came out in September 2018. Over 2 years ago. It is the successor to the most popular 3D printer: the Ender 3. I usually don’t do any research so I won’t be influenced by other reviewers but I did in this case so I could see what the differences are between the Ender 3 and Pro versions. It has been upgraded to a Meanwell power supply. Better mainboard layout. Wider extrusion for the bed to ride on, which should make the bed more stable. If you have done any research on 3D printers I would say it is impossible not to have heard about the Ender 3. With its low price, […]

Open Source ESP32 3D Printer Board Supports Marlin 2.0 Firmware

ESP32 3D Printer Controller Board

Espressif ESP32 processor was initially designed for cost-sensitive IoT projects thanks to its built-in WiFi & Bluetooth connectivity and low price, but the WiSoC’s fairly powerful two Xtensa cores found other uses such as face detection and audio applications among others. But a few people are now collaborating to bring ESP32 to the world of 3D printers with an open source hardware RepRap 3D printer controller board that has beta support in Marlin 2.0 RC1 firmware. There’s no commercially available ESP32 3D printer controller board right now, so only prototypes from the community are available. There are mainly two version of the boards: R1 and R2 designed by Simon Jouet, and at least one member – Felixstorm – made his own R2 board from the MIT licensed KiCad based design. R2 is a better design leveraging ESP32’s I2S interface to have more output pins and improve stepping. Felixstorm connected the […]

Creality CR-10 3D Printer Review – Part 2: Tips & Tricks, Octoprint, and Craftware

Hey Karl again with part 2 of my 3D printing experience with the CR-10, after the first part describing CR-10 3D printer setup and first prints. The intent is to share my experiences with the CR-10 with the perspective from a noob. I have to say if you are hard heading like I am, and do a lot of research but don’t fully listen to what you are reading, you are going to waste a lot of filament and time. I spent a couple hours a day for weeks with trial and error and watching the printer and how it works adjusting about a billion settings and testing. I am hoping this will help any current or future CR-10 owner speed up the learning curve. Measuring Filament Diameter The single biggest thing to improve my print quality I found was measuring the filament. I read about this several times but […]

Creality CR-10 3D Printer Review – Part 1: Unboxing, Setup, and First Prints

Today we are going to take a first look at the Creality CR-10 3D printer. This is a multipart series with the first part being unboxing and initial setup. I have no experience with 3D printing, and when I found out I would be doing this review I was ecstatic. It took a while to get shipped because of the wild popularity at Gearbest. I believe supply has caught up with demand. While waiting I read as much as I could about 3D printing. and I am glad I did. Creality CR-10 3D Printer Specifications 300 x 300 x 400mm build volume Nozzle diameter: 0.4mm Memory card offline print: SD card Prints up to 80mm/s (but slower is better) File format: G-code, JPG, OBJ, STL (I have only done g-code) 1.75mm Software – Cura; octoprint compatible CR-10 3D Printer Unboxing and Setup I had the CR-10 assembled and printing in […]
