# Setting Up Your FLSUN T1 Max

## About Your Printer

Great news! Your **FLSUN T1 Max** 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!

## T1 / S1 / V400 Series Setup Guide

### Step 1: Get your printer ready

## Before You Start: SSH

**This setup involves connecting to your printer using SSH.**

SSH is a way to communicate with your printer from your computer using text commands. You'll see a simple text window where you type (or paste) commands.

**What will you do with SSH?**
You'll run a few commands that we provide — mostly just copy and paste. SSH lets us configure settings on your printer that aren't accessible through its touchscreen.

**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/)

**We'll give you the exact commands to run.**
Some FLSUN T1 and S1 printers ship with outdated SSL certificates, which may prevent SimplyPrint from connecting properly. To fix this, you just need to run a quick command on your printer via SSH.

---

#### Connect to your printer via SSH

1. Find your printer's IP address (usually shown on the printer's screen).
2. Open a terminal:
- **Windows** → Command Prompt
- **Mac** → Terminal
3. Enter the following command, replacing
`[ip-address]` with your printer's IP:

```bash
ssh pi@[ip-address]
```

Example:

```bash
ssh pi@192.168.1.25
```

4. When prompted for a password, enter:

```
1
```

*(yes, the password is just "1" by default)*

*(it won't show as you type, just press ENTER)*

#### Run the certificate update fix

Once connected to your printer, paste this one-liner and press ENTER:

```bash
wget -qO- https://download.simplyprint.io/flsun/flsun-ssl.sh | sudo bash
```

This is a small script made by us to update the certificates to allow your printer to connect to our servers.

---

#### Verify success

If no errors are shown when running the command, the update worked.

Continue to the next step to enable SimplyPrint inside of your printer's web panel (Mainsail/Fluidd).
### Step 2: Enable SimplyPrint

Your printer runs Klipper firmware with a web interface (Mainsail or Fluidd). Here's how to connect it to SimplyPrint.

#### Find Your Printer's IP Address

You need to access your printer's web interface using its IP address (looks like `192.168.1.XXX`).

**How to find it:**
- **Printer's touchscreen:** Check Settings → Network or WiFi section (location varies by printer)
- **Router admin page:** Look for connected devices and find your printer's name
- **Network scanner app:** Use an app like "Fing" on your phone to scan your network
- **mDNS hostname:** Some printers respond to hostnames like `http://mainsail.local` or `http://fluidd.local`

Once you have the IP, type it in any web browser: `http://192.168.1.XXX`

You'll see your printer's web interface - either **Mainsail** (dark theme, sidebar on left) or **Fluidd** (lighter theme, gear icon for settings).

**Note:** Some printers run their interface on a specific port (e.g., `http://192.168.1.XXX:4408`). If the default doesn't work, check your printer's documentation.

#### Add `[simplyprint]` to Your Configuration

**If you use Mainsail:**

1. Click **Machine** in the left sidebar
2. Under **Config Files**, click `moonraker.conf`
   - NOTE: If you have a custom config file or one called `moonraker.generated.config`, edit that instead
3. Add this to the bottom of the file (with an empty line above):

```

[simplyprint]
```

4. Click **Save & Restart**

**If you use Fluidd:**

1. Click the **gear icon** (Configuration)
2. Under **Configuration Files**, click `moonraker.conf`
   - NOTE: If you have a custom config file or one called `moonraker.generated.config`, edit that instead
3. Add this to the bottom of the file (with an empty line above):

```

[simplyprint]
```

4. Click **Save & Restart**

#### Link Your Printer to SimplyPrint

After saving and restarting, your printer should appear automatically in SimplyPrint!

1. Go to [SimplyPrint.io](https://simplyprint.io) and log in
2. Click **Add Printer**
3. Check **Pending Printers** - your printer will likely appear there automatically
4. Click to add it and you're done! 🎉

**If your printer doesn't appear in Pending Printers:**

This can happen if you're not on the same network as your printer (different outgoing IP). In this case, use the setup code:

1. In your printer's web interface, click the **bell icon** (🔔) in the top bar
2. Find the "SimplyPrint Setup Request" notification
3. Copy the setup code and paste it in SimplyPrint under **Add Printer**

**Still having trouble?** See our troubleshooting guide: [Printer in setup isn't detected / can't find setup code](https://help.simplyprint.io/en/article/printer-in-setup-isnt-detected-cant-find-setup-code-3jyftm/). This also helps if you can't find Mainsail/Fluidd or the web interface isn't working.
