# Installation
This document provides a guide on how to install Moonraker & Mainsail on a Raspberry
Pi running Raspian/Rasperry Pi OS. Other SBCs and/or linux distributions
may work, however they may need a custom install script.

**Please don't use a octopi image!!!**

## Installing operation system image
It's recommend to use a clean Raspberry Pi OS 32-bit Lite (previosly called Raspbian)
image. You can download it [here](https://downloads.raspberrypi.org/raspios_lite_armhf_latest).

More information about the installtion of Raspberry Pi OS are
[here](https://www.raspberrypi.org/documentation/installation/installing-images/).

**If you have finished the installation and connected via ssh, you can continue.**

## Install Requirements
```
sudo apt update && sudo apt upgrade
sudo apt install git dfu-util
```

## Install Klipper
In this step, we install klipper.
```
cd ~
git clone https://github.com/KevinOConnor/klipper
cd ~/klipper
./scripts/install-octopi.sh
```

After you install Klipper with its dependencies you have to change the location
of the `printer.cfg`. This is definied in the `/etc/default/klipper` file. To edit
this file type:
```
sudo nano /etc/default/klipper
```
and then change:
```
KLIPPY_ARGS="/home/pi/klipper/klippy/klippy.py /home/pi/printer.cfg -l /tmp/klippy.log"
```
to:
```
KLIPPY_ARGS="/home/pi/klipper/klippy/klippy.py /home/pi/klipper_config/printer.cfg -l /tmp/klippy.log"
```
Save the file with `CTRL+O` and close the editor with `CTRL+X`.

At least you have to create the config and the virtual_sdcard directory with:
```
mkdir ~/klipper_config
mkdir ~/sdcard
```
and copy your `printer.cfg` in the `~/klipper_config` directory and restart klipper with
`sudo service klipper restart`. Please check the `klippy.log`, if Klipper starts
correctly and then continue the guide.

and check if you have following lines in your `printer.cfg`:
```
[virtual_sdcard]
path: ~/sdcard

[pause_resume]
[display_status]
```

## Install Moonraker (API)
You can now install the Moonraker application:
```
cd ~
git clone https://github.com/Arksine/moonraker.git
```

Finally, run Moonraker's install script:
```
cd ~/moonraker/scripts
./install-moonraker.sh
```

When the script completes it should start both Moonraker and Klipper. In
`klippy.log` you should find the following entry:\
`Moonraker: server connection detected`

### Configure Moonraker
A basic configuration that authorizes clients on a range
from 192.168.1.1 - 192.168.1.254 is as follows.

Create the configfile with `nano ~/moonraker.conf` and add the following lines:
```
[server]
host: 0.0.0.0
config_path: ~/klipper_config

[authorization]
enabled: true
trusted_clients:
    192.168.1.0/24
```

Restart Moonraker (sudo service mooonraker restart) and open the url `http://<printer-ip>:7125/printer/info` in your browser.

If you see a content like this
```
{"result": {"hostname": "voron250", "error_detected": false, "version": "v0.8.0-643-g528f9f25", "is_ready": true, "message": "Printer is ready", "cpu": "4 core ARMv7 Processor rev 4 (v7l)"}}
```

your API is working!

## Install Mainsail (webinterface)

### Install webserver & reverse proxy (nginx)
nginx is important to mount all components on port 80 and host the static files from Mainsail.
To install nginx you only need to execute:

```
sudo apt install nginx
```

now we create the config file with:

```
sudo nano /etc/nginx/sites-available/mainsail
```

and fill it with the following content:
```
map $http_upgrade $connection_upgrade {
    default upgrade;
    '' close;
}

upstream apiserver {
    #edit your api port here
    ip_hash;
    server 127.0.0.1:7125;
}

upstream mjpgstreamer {
    #edit your webcam port here
    ip_hash;
    server 127.0.0.1:8081;
}

server {
    listen 80 default_server;
    listen [::]:80 default_server;

    access_log /var/log/nginx/mainsail-access.log;
    error_log /var/log/nginx/mainsail-error.log;

    #web_path from mainsail static files
    root /home/pi/mainsail;

    index index.html;
    server_name _;

    #max upload size for gcodes
    client_max_body_size 200M;

    location / {
        try_files $uri $uri/ /index.html;
    }

    location /printer {
        proxy_pass http://apiserver/printer;
        proxy_set_header Host $http_host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Scheme $scheme;
    }

    location /api {
        proxy_pass http://apiserver/api;
        proxy_set_header Host $http_host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Scheme $scheme;
    }

    location /access {
        proxy_pass http://apiserver/access;
        proxy_set_header Host $http_host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Scheme $scheme;
    }

    location /websocket {
        proxy_pass http://apiserver/websocket;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection $connection_upgrade;
        proxy_set_header Host $http_host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_read_timeout 86400;
    }

    location /machine {
        proxy_pass http://apiserver/machine;
        proxy_set_header Host $http_host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Scheme $scheme;
    }

    location /server {
        proxy_pass http://apiserver/server;
        proxy_set_header Host $http_host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Scheme $scheme;
    }

    location /webcam/ {
        proxy_pass http://mjpgstreamer/;
    }
}
```

Create directory for static files and active nginx config:
```
mkdir ~/mainsail
sudo rm /etc/nginx/sites-enabled/default
sudo ln -s /etc/nginx/sites-available/mainsail /etc/nginx/sites-enabled/
sudo service nginx restart
```

Now you can check again the API if it works with the reverse proxy.
Open the url `http://<printer-ip>/printer/info` in your browser. if you see a content like this:
```
{"result": {"hostname": "voron250", "error_detected": false, "version": "v0.8.0-479-gd586fb06", "is_ready": true, "message": "Printer is ready", "cpu": "4 core ARMv7 Processor rev 4 (v7l)"}}
```

Now we can install Mainsail (static httpdocs).

### Install httpdocs
Now you can download the current mainsail static data
```
cd ~/mainsail
wget -q -O mainsail.zip https://github.com/meteyou/mainsail/releases/download/v0.1.3/mainsail-beta-0.1.3.zip && unzip mainsail.zip && rm mainsail.zip
```
Now it should be possible to open the interface: `http://<printer-ip>/`.

### Change the Hostname (optional)
to use the hostname instate of the ip, you can install the avahi-daemon:
```
sudo apt install avahi-daemon 
```

and you can config your hostname:
```
sudo raspi-config
```
in 2 Network Options > N1 Hostname you can edit your hostname of your raspberry pi.
After a reboot you can use `http://<hostname>.local/` to open the webinterface.
