# Setting Up Your Creality K2 SE ## About Your Printer Great news! Your **Creality K2 SE** is a "smart" printer that already runs Klipper firmware. This makes setup much easier. **What this means:** Your printer already has built-in networking and runs Klipper (advanced firmware). It has a web interface (usually "Mainsail" or "Fluidd") that SimplyPrint can connect to directly. We can install the SimplyPrint companion software directly **on** the printer itself. **No extra hardware needed!** You just need to enable SimplyPrint in your printer's web interface. **What you'll need:** - Your printer connected to your WiFi network - Access to the printer's web interface (usually at `http://your-printer-ip`) - A SimplyPrint account Let's get started with the setup! --- ## K2 Series Setup Guide ### Step 1: Readying K2 ## Before You Start: Root Access **This printer requires enabling "root access" to connect to SimplyPrint.** Don't let the technical name worry you — this is usually as simple as navigating to a setting on your printer's screen and checking a box. You'll also use "SSH" to run a few commands. **What is root access?** Think of it like unlocking "administrator mode" on your printer. It gives you (and SimplyPrint) the ability to add features and make changes that the standard interface doesn't allow. **Why do I need it?** Your printer manufacturer has locked down certain features. By enabling root access, you're giving yourself permission to use your printer to its full potential. **Is this "hacking" or "jailbreaking"?** Not really! In most cases, the manufacturer has provided this option themselves — it's just tucked away in the settings. You're using a feature they built in. **What does SimplyPrint actually do?** We simply enable our component in the printer's existing software — we don't install packages or make invasive changes. The process is minimal, and you can usually factory reset your printer to undo everything if needed. **A note about warranty** Some manufacturers mention that enabling root access may affect your warranty. The risk is low — we haven't had a single known case of a SimplyPrint user being denied warranty service because of this. But it's your call. **We'll show you exactly where to find this setting and what commands to run.** ### You'll Also Use SSH This setup requires SSH — a way to send text commands to your printer from your computer. We know it sounds technical, and we wish we could avoid it, but unfortunately the printer's design leaves us no other option. The good news: it's simpler than it sounds. You'll just copy and paste a few commands we provide — no coding required. **New to SSH?** No problem! We have a beginner-friendly guide: [SSH: What is it and how to use it](https://help.simplyprint.io/en/article/ssh-what-is-it-and-how-to-use-it-1pb1aq0/) ### Set up SimplyPrint on the Creality K2 In this guide we will go through: 1. Find your K2's IP address 2. Enable root access and get the password 3. Enable SimplyPrint in Fluidd (via SSH) 4. Access your web interface --- ### 1. Find your K2's IP address 1. On the touchscreen navigate to **"Settings"** → **"Network"**. 2. Note down the K2's IP address shown under your network name/SSID. --- ### 2. Enable root access 1. On the touchscreen navigate to **"Settings"** and scroll down to select **"Root account information"**. 2. Read the disclaimer, check **"I have read and understood the risks of Root login"** and wait 30 seconds before pressing **"Ok"**. 3. Note down the generated root password. --- ### 3. Enable SimplyPrint in Fluidd (via SSH) 1. Open a terminal or SSH client on your computer. 2. Connect to the K2 using the IP address and root password you noted: ```bash ssh root@[IP_ADDRESS] ``` 3. When prompted for a password, enter the password you noted _(the password won't show up while typing - don't worry; that's normal)_. 4. Once connected, run the command below to enable SimplyPrint and restart "Moonraker", which is the firmware's built-in API that includes SimplyPrint: ```bash python3 -c "import urllib.request;print(urllib.request.urlopen('https://download.simplyprint.io/creality/k2/k2-setup.sh').read().decode())" | sh ``` **What does this script do?** This script locates the `moonraker.conf` file that your printer uses, which can either be in `/usr/data/moonraker` or `/data/moonraker`. It then adds the SimplyPrint configuration (`[simplyprint]`) to the file and restarts Moonraker. --- ### 4. Add your printer to SimplyPrint Now everything should be ready! The printer should be connected to SimplyPrint! Open up the SimplyPrint web dashboard on a computer or phone **on the same network** as your K2, where it should show up as a pending printer in the "Add printer" flow. --- ##### **Not showing up inside SimplyPrint?** Find the printer setup code in the printer's local web interface. 1. Open a web browser on your computer or phone. 2. Using the IP address you noted, navigate to `http://[IP_ADDRESS]:4408` to access the Fluidd panel hosted by your K2. 3. Find the "Notification" bell icon in the top right corner and click it 4. Here you should see a **"SimplyPrint Setup Request"** with a 4-character setup code; use this If it doesn't work for you, try going through the guide again **very carefully**. Missed steps is the most common reason for printers not showing up. --- ##### **Known limitations** Due to limitations in Creality's firmware, the following features are not available: - Estimated time remaining for prints - Layer progress (current layer number) ### 4. Access your web interface 1. Open a web browser on your computer or phone. 2. Using the IP address you noted, navigate to `http://[IP_ADDRESS]:4408` to access the Fluidd panel hosted by your K2. --- And that's it! Your Creality K2 is now running Klipper with SimplyPrint enabled. --- ## Frequently Asked Questions ### Which K2 model do I have? All K2 variants (K2, K2 Plus, K2 Pro, Combo versions) use the same setup process. Don't worry about the specific model. ### Where do I find my printer's IP address? On the K2 screen, go to Settings > Network. The IP address is displayed there.
