Mainsail for Klipper - A Detailed Overview

Klipper firmware has changed the game in 3D printing. It doesn’t work inside the printer’s microcontroller like marlin firmware but uses a separate more powerful computer, like a Raspberry Pi or other SBC, for better performance. This means better prints, quicker speeds, and easier ways to tweak your printer. But, setting up Klipper can be tough since it uses text files and commands for configuration and edit the settings and may require high technical knowledge.

That’s where Mainsail and other web interfaces comes in. Mainsail is a user-friendly interface that makes it easier to use Klipper’s advanced features in easy and direct way through a web browser.

Here’s what makes Mainsail so handy:

Keep an Eye on Your Printer 

Watch your printer do its thing and check on important stuff like temperature, how much filament you’re using, where everything’s moving, and how far along your print is. It’s all shown in real-time with neat charts and info.

Easy Printer Commands 

Forget about typing in tricky commands. Mainsail lets you control your printer from your web browser. You can start, stop, or cancel your prints with a click. Change the heat settings with a slide or type in numbers if you need to be super exact. You can even move your printer around right from the screen, which is great for getting things just right.

Sort Out Your Files 

Keep all your printing files in order with Mainsail. Upload your Gcode files, put them in folders to stay organized, and look back at your print history to see how long things took, how much filament you used, and when you printed them.

Watch Your Prints Live 

Connect a camera to Mainsail and you can watch your prints live. This way, you can keep an eye on things from anywhere and catch any problems early.

Make Printing Easier with Macros 

Set up custom macros to make controlling your printer easier. They can do the boring stuff for you, like leveling the bed, changing filament, or setting up your extruder, so you don’t have to write long commands and forgot the G-code commands.

Tweak Your Printer Settings 

With Mainsail, you can dive into Klipper and change your printer’s settings and configuration to make it work just how you like. Plus, you can keep Klipper and Mainsail updated with the latest cool features and fixes.

Add More with Plugins 

Make Mainsail even better with plugins and added components. There’s a bunch you can add, like ones for making timelapses of your prints.

Now that you know what Mainsail is and its significance for your Klipper setup, let’s walk through the steps to get it installed.

Getting start with mainsail

There are four primary methods for installing Mainsail:

MainsailOS (Recommended): This pre-built operating system is specifically designed for Klipper and Mainsail, offering a streamlined installation process. MainsailOS is a prebuilt image for single board computers that already includes Mainsail, Moonraker and Klipper.

Manual Installation: For users who prefer a more hands-on approach, manual installation offers greater control over the setup process. However, this method requires a deeper understanding of the underlying components.

Docker-Based Installation: For users familiar with Docker, this method allows running Mainsail in an isolated container environment. While offering advantages in terms of isolation and portability, it requires a working knowledge of Docker concepts.

KIAUH - Klipper Installation

KIAUH stands for "Klipper Installation And Update Helper" and is a tool that helps you install or upgrade Klipper, Moonraker, Mainsail, and other extensions.

Detailed instructions for each installation method can be found in the official Mainsail documentation, ensuring a smooth setup process regardless of your chosen approach.
