Before You Start: Root Access

Your Creality HI 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. You can usually factory reset to undo everything.

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.

Set up SimplyPrint on the Creality HI

In this guide we will go through:

  1. Find your HI'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 HI's IP address

  1. On the touchscreen navigate to "Settings" → "Network".
HI homescreen with Settings button HI Settings → Network button
  1. Note down the HI'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".
HI homescreen with Settings button HI Settings → Root account information
  1. Read the disclaimer and wait 30 seconds before checking "I have read and understood the risks of root login" and then pressing "Ok".

  1. Note down the generated root password.

3. Enable SimplyPrint in Fluidd (via SSH)

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.

  1. Open a terminal or SSH client on your computer.
  2. Connect to the HI using the IP address and root password you noted: 
ssh root@[IP_ADDRESS]

For example; ssh [email protected]

  1. When prompted for a password, enter the password you noted (the password won't show up while typing - don't worry; that's normal).
  2. Once connected, run the command below to enable SimplyPrint and restart "Moonraker", which is the firmware's built-in API that includes SimplyPrint: 
python3 -c "import urllib.request;print(urllib.request.urlopen('https://download.simplyprint.io/creality/hi/hi-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. Access your web interface

  1. Open a web browser on your computer.
  2. Using the IP address you noted, navigate to http://[IP_ADDRESS]:4408 to access the Fluidd panel hosted by your HI.

And that's it! Your Creality HI is now running Klipper with SimplyPrint enabled.

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)
