What are Mainsail, Fluidd, and OctoPrint?​

Mainsail, Fluidd, and OctoPrint are web interfaces for 3D printers that let you monitor and control your printer remotely. These software provide an easy way to interact with your printers and give you access to various features that enhance the remote user experience of 3D printing.

Fluidd and Mainsail OS are explicitly developed to run with Klipper firmware on your 3D printers. These software act as a communication bridge between you and your 3D printer and give you a way to monitor, control, and interact with your 3D printer wirelessly.

In contrast, Octoprint is developed as a generic 3D printer control software that gives you wireless access to your 3D printers. It can run on various firmware, including Klipper, and is developed specifically for remote 3D printing. Like Mainsail and Fluidd, Octoprint, too, runs in a web browser interface and has several plugins that extend the software’s usability.

All three of these software are free to download and completely open-source, contributing to their fast development and suite of excellent features. This article will explain all three software in detail and learn their differences and similarities.

Let’s get started.

Klipper has recently caught many eyeballs with its fantastic features and utility for 3D printing. It's a firmware that runs off a Raspberry Pi board and lets you execute high-speed 3D printing and extract the most out of your 3D printer. It has improved motion planning and precise stepper motor control and delivers excellent print quality with a slight tuning.

You can find several ways of setting up Klipper for any 3D printer. But, in this guide, we'll understand the entire process of installing Klipper on an Ender 3 3D printer using the Mainsail OS and Raspberry Pi imager. Together, Klipper and Ender 3 are one of the most popular combos, and once you grasp the idea, it's easy to emulate it for other 3D printers.

Without any further adieu, let's get started, Klipping.

What is Klipper?​

Klipper is a free and open-source 3D printer firmware that runs using your printer's controller board and an external processing unit, usually a Raspberry Pi board. It's maintained by Kevin O Connor on GitHub but has contributions from several other developers. The first version was released in 2016, and the Klipper firmware has evolved considerably over the years.

It utilizes the extra processing power of the Pi to compute, execute and run your 3D printer at faster speeds with higher precision. Voron 3D printers are famous for their fast print speeds and printing quality, and these printers use a customized version of the Klipper firmware to run at speeds above 200 mm/s with minimal loss in print quality.

Its open-source nature and strong community have significantly contributed to its list of features, and the current Klipper firmware offers far more than fast print speeds.

Why should you install Klipper on your 3D printer?​

The Raspberry Pi's extra computing power helps Klipper compute, execute and deliver precise stepper motor motion. It finely calculates and controls the movement of your stepper motor, ensuring a smooth printing process.

Its 'Smooth pressure advance' feature predicts the filament pressure in the nozzle and reduces the filament flow when the nozzle reaches the end of an edge or line. This function reduces filament oozing and minimizes the stringing effects at high print speeds.

Klipper readily works with Octoprint, supports multiple controllers on a single 3D printer, and is widely available for all 3D printers. It can transform an old and slow 3D printer into a fast machine that can easily put up with the latest high-end 3D printers.

Now that we have an overview of Klipper and its features let's dive into setting it up with the Mainsail OS for an Ender 3 3D printer.

Every electronic device is made up of three parts: hardware, software, and firmware. While the first two are more well-known, it is the firmware that connects the hardware to the software. Klipper is one such 3D printer firmware setup that uses Raspberry Pi to work alongside your 3D printer's mainboard. Klipper firmware is relatively new, and we intend to explain what it is and why you need it.

What is Klipper 3D printer firmware?​

We're sure you've heard of the Marlin firmware. This is the most popular and widely used 3D printer firmware. In fact, your 3D printer or printers must be running on a Marlin firmware. We are certain of it. And why not? It was one of the first and most widely used firmware that delivered consistent results.

But did you know there are several alternatives to Marlin? Yes, there are, and the Klipper 3D printer firmware is one such option that is becoming increasingly popular due to the benefits it provides.

Klipper is an open-source 3D printer firmware developed by Kevin O'Connor, the original author and current maintainer of Klipper. It allows interaction between your 3D printer hardware, such as motors and sensors, and software, such as slicers, in order to understand the gcode commands used to 3D print an object.

It differs from traditional 3D printer firmware, which runs on a single mainboard. Klipper is designed to work with a 3D printer mainboard and a single-board computer, such as a Raspberry Pi to eliminate the issues of low computing power. Klipper works in tandem with the Raspberry Pi and uses the extra computing power to assist the mainboard in processing commands, allowing you to print more quickly and precisely.

We know you all enjoy timelapse videos in which everything appears to run fast. With reference to OctoPrint, a timelapse video would refer to the videos where the product appears to grow out of thin air. It is almost surreal, which is what makes it all the more appealing. You may know how to create a timelapse, also called Octolapse, but do you know the best camera for an Octolapse? Well, choosing a camera itself is complicated, let alone the best one.

Well, we have decided to list down a few good ones to help you choose the best camera for Octolapse.

What is Octolapse?​

Let me introduce myself first. I’m Mitch, a team member of Obico and I’m in this world for 25 years now. I live in Belgium and I like longboarding, riding with my motorcycle and hanging out with my friends. I’m also interested in formula one, MotoGP, DnD and 3D printing. I am very into technology to make my life easier. You could call me a geek although my friends prefer the word nerd because I’m also a big superhero fan. The word nerd isn’t as offensively used anymore then back in the days anyway so I’m cool with that.
