Introduction

Klipper, an open-source 3D printer firmware, can be a game-changer for your Creality Ender 3 S1. Recognized by enthusiasts and experts alike, this firmware enables superior print speeds and enhanced precision. Originally discussed by the 3D Print Beginner, this guide aims to help you navigate the installation process seamlessly.

What is Klipper?

Klipper is open-source firmware that works in conjunction with a Raspberry Pi and your printer’s mainboard. Unlike traditional firmware that runs exclusively on the printer’s hardware, Klipper uses the processing power of a Raspberry Pi to handle computational tasks. This setup allows for higher speeds and improved control of the printing process, combining the strengths of both pieces of hardware.

Why Install Klipper?

Installing Klipper on your printer offers several advantages. First and foremost, you’ll experience faster printing speeds compared to the stock firmware. Additionally, Klipper allows remote control of your 3D printer via Wi-Fi and a web interface. With advanced features like Pressure Advance and Input Shaper, you can achieve better print quality and reduced ghosting.

Prerequisites

Before we proceed, ensure you have the following items:

Raspberry Pi: Any version will work, but newer models are more efficient.
MainsailOS or FluiddPi: These are user-friendly software options for managing your printer through a web interface.
Creality Ender 3 S1: Ensure it’s the stock version so the steps align perfectly.
Quality Power Supply: The Raspberry Pi requires a stable power source.
Type C Cable: Required to connect the Ender 3 S1 to the Raspberry Pi.

Before You Begin

Installing Klipper isn’t a casual weekend project; it requires some experience with 3D printers and general hardware. This guide will walk you through every step, but please read through the entire guide before starting to familiarize yourself with the risks and tasks involved. Also, keep in mind that the stock touchscreen on the Ender 3 S1 will be disabled after this procedure. For better ease-of-use, it’s recommended to get a BIQU PI TFT50 touchscreen and KlipperScreen.

Software Installation

To start, you’ll need to install either MainsailOS or FluiddPi, which are popular choices for a web interface to control your Klipper setup. Both options are straightforward to install on your Raspberry Pi.

Download MainsailOS or FluiddPi:
- Visit the official websites to download the image file for MainsailOS or FluiddPi.
Flash the Image:
- Use a tool like Balena Etcher to write the image to your microSD card.
Initial Setup:
- Insert the microSD card into your Raspberry Pi.
- Connect your Raspberry Pi to your network via Ethernet or Wi-Fi.
Access Web Interface:
- Once connected, you can access the control interface via your web browser by entering the local IP address of your Raspberry Pi.
Install Klipper Using KIAUH:
- KIAUH (Klipper Installation And Update Helper) simplifies the installation and management of Klipper. Follow the instructions provided on the KIAUH GitHub page to install it.

Firmware Preparation and Installation

Building and flashing the Klipper firmware onto your printer involves a series of specific steps.

Access Raspberry Pi via SSH:
- Software like Putty can be used for this. Ensure you have the IP address of your Raspberry Pi.
Building Klipper:
- Once connected, follow the command-line prompts to build the Klipper firmware. You’ll need to specify configurations like your CPU type—typically STM32F401 or STM32F103 for the Ender 3 S1.
- The resulting firmware file will be saved on your Raspberry Pi.
Flash Firmware:
- Copy the compiled firmware file to an SD card.
- Insert the SD card into the Ender 3 S1 and reboot the printer to flash the new Klipper firmware.

Connecting Klipper

After successfully flashing the firmware, you’ll need to configure Klipper to communicate effectively with your 3D printer.

Copy Configuration File:
- Move or copy the Klipper configuration file to the appropriate directory on Mainsail.
Web Interface Setup:
- Access the Mainsail or Fluidd web interface to complete setting up the connection between Klipper and your printer.
- Follow the on-screen prompts to enter your printer’s specific settings and calibrations.
Calibration:
- Perform initial calibrations to ensure your printer is correctly tuned. This includes setting steps/mm for your motor, home offsets, and extruder steps/mm.

Calibration Step	Description
X, Y, Z Steps/mm	Ensure each axis moves accurately.
Extruder Steps/mm	Calibrate filament extrusion amounts.
Home Offsets	Set accurate home positions.

Reverting to Stock Firmware

If for any reason you want to switch back to the original firmware, the steps are straightforward.

Download Stock Firmware:
- Get the latest stock firmware from the Creality website.
Flash Stock Firmware:
- As with the Klipper firmware, copy the stock firmware file to an SD card and insert it into the Ender 3 S1.
- Reboot the printer to reset to stock firmware.

Extras

With your Klipper setup, you can now access additional resources to optimize your 3D printing experience.

Tuned IdeaMaker Profile:
- A specially tuned IdeaMaker profile for Klipper on the Ender 3 S1 is available. This profile enhances print quality and efficiency.
Community Support:
- Engage with the 3DPrintBeginner community if you run into any issues or have questions. Sharing experiences and solutions can be incredibly beneficial.
