Flsun V400: Why I Bought One?

Flsun recently released a new delta printer called V400, and it got me interested. Flsun claims it can print at speeds of 400mm/s in the stock configuration. It took me a lot of tuning to reach that speed on my Voron 2.4, and I know it’s a pretty high target. I decided to order one and I’m going to share my reasons (full review will come when I receive the printer).

Voron on 48V: How Fast Can It Go?

Recently, it has become a lot easier to run your Voron on 48V: the latest controller boards support voltages up to 60V and high voltage stepper drivers like TMC5160 are readily available. Does it mean the future of 3D printing is in 48V systems? Should you use 48V in your next build? I will push my 24V printer to find its limit and then test how much faster it can go on 48V.

Klipper on Orange Pi Zero 2

If you want to use Klipper firmware on your 3D printer, you typically add a single board computer (SBC) like Raspberry Pi. Raspberry Pi is great, and it used to be affordable, but nowadays, due to chip shortage and supply chain issues, its price has skyrocketed, and even if you’re willing to pay it, they are out of stock most of the time. I got my hands on an alternative board called Orange Pi Zero 2, and I’m going to test how it compares to Raspberry Pi Zero 2 and Raspberry Pi 4.

Trianglelab CHC or Rapido?

Rapido is one of the best high flow hot-ends, but it comes with a premium price tag. Trianglelab recently announced CHC series hot-ends that feature a similar ceramic heater (and similar performance?) at 1/3 of the price. I will compare both hot-ends and tell you how they stack up.

Why I prefer Klipper over Marlin?

When it comes to 3D printers, there are three firmware options you can run: Klipper, Marlin, or RepRap firmware. Most printers are shipped with a customized version of Marlin configured for the specific hardware and manufacturer’s branding. If you decide to modify the printer, you will likely have to flash the firmware. Let’s look at their differences and why I prefer Klipper over the others.

Which controller board to choose for your Voron?

Voron 2.4 and Voron Trident are advanced 3D printers running more stepper motors than a basic 3D printer. You used to need two controller boards to run these printers, but recently multiple affordable 8 stepper boards were released. I tested and compared BIGTREETECH Octopus, Manta M8P, FYSETC Spider, Makerbase MKS Monster 8 and Mellow Super 8.

Updated in Septemper 2023 to include the latest generation of boards with integrated Klipper host.

TinyXL: Compact 3D Printer Concept

I was looking to build a smaller printer, and I liked Tiny-M’s overall size and design, but I also had some ideas for improvements. I wanted it to be more space-efficient, and I started tinkering in the CAD. When PrusaXL was revealed, I thought the open front was very practical and decided to use the same approach in my design. That’s how the concept of TinyXL was born: based on Tiny-M and inspired by PrusaXL.


Choosing a 36mm extruder motor

NEMA14 36mm round steppers are becoming increasingly popular extruder stepper motors due to their small weight and high torque. I have tested LDO-36STH17-1004AHG, LDO-36STH20-1004AHG, and Moons’ 36mm 20mm steppers, and I will share my thoughts on them.

Tips For Building A Voron

Voron 3D printers are great but building one can be challenging. The assembly manual is a great resource, and there are plenty of YouTube guides you can watch. I will share some of my own tips to help you with the build.

Phaetus Rapido: What's New?

Phaetus recently announced Rapido hotend and it packs some of the advantages of E3D Revo in a more traditional package. Let’s break down the new features and compare it to other hotends.
