Heads up: This setup has a technical step

You'll need to use something called "SSH" to run a few commands.

We know — we wish we could skip this part too. But your device doesn't give us a simpler option. The good news: it's just copying and pasting. If you can follow instructions, you can do this.

Why is SSH needed?

Your printer manufacturer doesn't provide a simpler way for platforms like SimplyPrint to connect. SSH is how we work around that limitation to give you the features you need.

What will you do with SSH?

You'll run a few commands that we provide - mostly just copy and paste. No coding required.

New to SSH? No problem!

SSH: What is it and how to use it

We'll give you the exact commands to run.

Use at your own risk: This script has been tested on many printers and installs a separate Moonraker instance alongside your existing setup - it does not modify your Klipper configuration or firmware. However, any modification to your printer's software carries some risk. We cannot guarantee compatibility with every printer or configuration, and we are not responsible for any issues that may arise. If something goes wrong, you can typically remove the installed files and restart your printer to revert to its original state.

1. Find your printer's IP address

You need to know your printer's IP address to connect to it.

Find the IP address
  • The IP address usually shows on your printer's screen or in its network settings
  • Can't find it? Check your router settings for connected devices
  • Or use a network scanner tool like Angry IP Scanner

2. Connect via SSH

SSH lets you run commands on your printer's built-in computer.

Yes, this is the annoying technical part. We're sorry — we've tried everything to avoid it, but your device simply doesn't give us another option.

But here's the thing: it's easier than it looks. You're just going to copy-paste a few commands. That's it. Pick your computer type below and follow the steps — we'll walk you through every click.

Important: The IP address must be just the numbers (e.g., 192.168.1.42). Do not include http://, slashes, or port numbers.
Windows 10 / 11
  1. Press Win + X and select "Terminal" or "PowerShell"
  2. Type the SSH command (replace the placeholders):
    ssh username@ip-address
    Example: ssh [email protected]
  3. If asked "Are you sure you want to continue connecting?", type yes and press Enter
  4. Enter the password when prompted
    The password won't show as you type — that's normal! Just type it and press Enter.
macOS
  1. Press Cmd + Space to open Spotlight, type "Terminal", and press Enter
  2. Type the SSH command (replace the placeholders):
    ssh username@ip-address
    Example: ssh [email protected]
  3. If asked "Are you sure you want to continue connecting?", type yes and press Enter
  4. Enter the password when prompted
    The password won't show as you type — that's normal! Just type it and press Enter.
Linux
  1. Open Terminal (usually Ctrl + Alt + T, or find it in your applications menu)
  2. Type the SSH command (replace the placeholders):
    ssh username@ip-address
    Example: ssh [email protected]
  3. If asked "Are you sure you want to continue connecting?", type yes and press Enter
  4. Enter the password when prompted
    The password won't show as you type — that's normal! Just type it and press Enter.
Chromebook
First-time setup: You need to enable Linux on your Chromebook (one-time only).
  1. Enable Linux (skip if already done):
    • Open Settings
    • Go to Advanced → Developers
    • Turn on "Linux development environment"
    • Follow the setup wizard (takes a few minutes)
  2. Open the "Terminal" app from your app launcher
  3. Type the SSH command (replace the placeholders):
    ssh username@ip-address
    Example: ssh [email protected]
  4. If asked "Are you sure you want to continue connecting?", type yes and press Enter
  5. Enter the password when prompted
    The password won't show as you type — that's normal! Just type it and press Enter.
Common issues
  • "Connection refused" — Make sure you're on the same network and the IP address is correct.
  • "Permission denied" — Double-check your username and password.
  • "Host key verification failed" — The device was reset or reinstalled. Remove the old key with: ssh-keygen -R <ip-address>
Using a tablet or phone?

While there are SSH apps available for Android and iOS, we recommend using a computer for SSH connections. A proper keyboard and screen make typing commands much easier.

Once your terminal is open, connect to your printer: 

ssh mks@YOUR_IP_ADDRESS

Replace YOUR_IP_ADDRESS with your printer's IP address, e.g. ssh [email protected]

When prompted for a password, type makerbase and press Enter. The password won't show as you type - that's normal.

3. Fix date if you encounter SSL errors 

sudo date -s '2026-04-10'

Copy-paste the command above - it already contains today's date. You may be prompted for a password - use makerbase.

4. Install SimplyPrint

Now we'll download and run the installer script.

The script requires bash, git, and Python 3.7+ on the printer. These are pre-installed on virtually all Klipper printers.

Step 1: Download the installer script: 

wget -O moonraker-sp.sh https://download.simplyprint.io/klipper/moonraker-sp.sh && chmod +x moonraker-sp.sh

Step 2: Run the installer: 

./moonraker-sp.sh --install

You may be prompted for a password - use makerbase.

5. Get your setup code

Once the script finishes, it will display your printer's setup code.

Use this code to link your printer in the SimplyPrint panel, or check if your printer shows up automatically under Pending Printers.

What does this script do? It installs a separate, up-to-date Moonraker instance with the SimplyPrint component alongside your existing printer setup. Your existing Klipper configuration and web interface (Mainsail/Fluidd) are not modified. The new Moonraker instance runs on a different port and only handles the SimplyPrint connection.
