# 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 unzip
```

## 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` and add the UDS. 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 -a /tmp/klippy_uds"
```
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
```
Note that the above configuration can differ! Make sure you determine your local IP and replace the IP from the example configuration above with the one from your own network.

Restart Moonraker (`sudo service moonraker 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 files with:

```
sudo touch /etc/nginx/sites-available/mainsail
sudo touch /etc/nginx/conf.d/upstreams.conf
sudo touch /etc/nginx/conf.d/common_vars.conf
```

Each file can be filled with the following content:

`sudo nano /etc/nginx/conf.d/upstreams.conf`
```
# /etc/nginx/conf.d/upstreams.conf

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;
}
```

`sudo nano /etc/nginx/conf.d/common_vars.conf`

```
# /etc/nginx/conf.d/common_vars.conf

map $http_upgrade $connection_upgrade {
    default upgrade;
    '' close;
}
```

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

```
# /etc/nginx/sites-available/mainsail

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;

    #disable this section on smaller hardware like a pi zero
    gzip on;
    gzip_vary on;
    gzip_proxied any;
    gzip_proxied expired no-cache no-store private auth;
    gzip_comp_level 4;
    gzip_buffers 16 8k;
    gzip_http_version 1.1;
    gzip_types text/plain text/css text/xml text/javascript application/x-javascript application/json application/xml;

    #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/v0.2.6/mainsail-beta-0.2.6.zip && unzip mainsail.zip && rm mainsail.zip
```
Now it should be possible to open the interface: `http://<printer-ip>/`.

### Important macros
if you want to get the full experience with mainsail and klipper virtual_sdcard print,
you should use these macros, or use them as templates for your own.

[Link to the macros doc](macros.md)

### 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.
