Keep track of your inventory of 3D-printer filament spools.

Keep track of your inventory of 3D-printer filament spools.

Spoolman is a web service that helps you keep track of your filament spools and how they are being used.

It acts as a database, where other printer software such as Octoprint and Moonraker can interact with to have a centralized place for spool information. For example, if used together with Moonraker, your spool weight will automatically be reduced as your print is progressing.

It exposes a HTTP API which services can interact with. See the OpenAPI description for more information.

Client

Spoolman includes a web-client that lets you directly manipulate all the data. It also has a few additional nice features such as label printing.

Integration status

Spoolman is still relatively new, so support isn't widespread yet, but it's being actively integrated to multiple different projects.

• ✔️ Moonraker - See the Moonraker Documentation
  • ✔️ Fluidd
  • ✔️ KlipperScreen
  • ✖️ Mainsail
• ✖️ Octoprint - A plugin is in progress: OctoPrint-Spoolman

Installation

Spoolman can interact with any of the following databases: SQLite, PostgreSQL, MySQL, MariaDB, CockroachDB. By default, SQLite is used which is a simple no-install database solution that saves to a single .db file located in the server's user directory.

Using Docker

The easiest way to run Spoolman is using Docker. Docker is a platform for developing, shipping, and running applications in containers. Containers are lightweight, portable, and self-contained environments that can run on any machine with Docker installed.

To install Docker on your machine, follow the instructions for your operating system on the Docker website. Docker also includes the docker-compose tool which lets you configure the container deployment in a simple yaml file, without having to remember all the command line options.

Here is a sample docker-compose config to get you started. Copy-paste it into a file called docker-compose.yml and run docker-compose up -d to start it. If you want to use the SQLite database as in this sample, you must first create a folder called data in the same directory as the docker-compose.yml, then you should run chown 1000:1000 data on it in order to give it the correct permissions for the user inside the docker container.

version: '3.8'
services:
  spoolman:
    image: ghcr.io/donkie/spoolman:latest
    restart: unless-stopped
    volumes:
      - ./data:/home/app/.local/share/spoolman
    ports:
      - "7912:8000"
    environment:
      - TZ=Europe/Stockholm # Optional, defaults to UTC

Once you have it up and running, you can access the web UI by browsing to http://your.ip:7912.

If a new version of Spoolman has been released, you can update to it by first browsing to the directory where you have the docker-compose.yml file and then running docker-compose pull && docker-compose up -d.

If you want to connect with an external database instead, specify the SPOOLMAN_DB_* environment variables from the table below.

Variable	Description
SPOOLMAN_DB_TYPE	Type of database, any of: postgres, mysql, sqlite, cockroachdb
SPOOLMAN_DB_HOST	Database hostname
SPOOLMAN_DB_PORT	Database port
SPOOLMAN_DB_NAME	Database name
SPOOLMAN_DB_USERNAME	Database username
SPOOLMAN_DB_PASSWORD_FILE	Path of file which contains the database password. Can be used instead of SPOOLMAN_DB_PASSWORD if desired.
SPOOLMAN_DB_PASSWORD	Database password
SPOOLMAN_DB_QUERY	Query parameters for the database connection, e.g. set to unix_socket=/path/to/mysql.sock to connect using a MySQL socket.
SPOOLMAN_LOGGING_LEVEL	Logging level, any of: CRITICAL, ERROR, WARNING, INFO, DEBUG, defaults to INFO.
SPOOLMAN_AUTOMATIC_BACKUP	Automatic nightly DB backups for SQLite databases. Enabled by default, set to FALSE to disable.

Development

Client

To test out changes to the web client, the best way is to run it in development mode.

Prerequisities:

• NodeJS 16 or above installed, along with NPM. Running node --version should print a correct version.
• A running Spoolman server, with the following two environment variables added in the docker-compose.yml:

    environment:
      - FORWARDED_ALLOW_IPS=*
      - SPOOLMAN_DEBUG_MODE=TRUE

Instructions:

1. Open a terminal and CD to the client subdirectory
2. Run npm install. If it doesn't succeed, you probably have an incorrect node version. Spoolman is only tested on NodeJS 16.
3. Run echo "VITE_APIURL=http://192.168.0.123:7901/api/v1" > .env, where the ip:port is the address of the running Spoolman server. This should create a .env file in the client directory. If you don't already have one running on your network, you can start one up using the docker-compose.yml showed above.
4. Run npm run dev. The terminal will print a "Local: xxxx" URL, open that in your browser and the web client should show up. Your existing spools etc in your Spoolman database should be loaded in.
5. Any edits in .ts/.tsx files will be automatically reloaded in your browser. If you make any change to .json files you will need to F5 in your browser.
