  • Commit spools usage to Spoolman
• Spools filtering
• Check spools before starting a print
  • Ask the user if the selected spool is correct
  • Warn when no spool is selected
  • Warn when selected spool does not have enough material
  • Warn on tools mismatach (multi-tool setups)
• Advanced spools verification
  • Configurable "safety buffer" (Bowden setups)
  • Warn when wrong spool material has been selected (PrusaSlicer / OrcaSlicer gcodes)

Setup

Install via the bundled Plugin Manager or manually using this URL:

https://github.com/mdziekon/octoprint-spoolman/archive/master.zip

After installing the plugin, you have to set it up, by:

• Providing your Spoolman's instance address.
  • This should be either hostname or IP address (whatever works in your network) followed by the port (eg. 7912). Ideally, you should use secure connection (HTTPS) to connect your Octoprint with Spoolman.
  • Remember, your Spoolman's instance has to be reachable in your local network, otherwise the plugin won't work.
  • For reference, see Screenshots - Spoolman's setup

Spoolman's setup

Development

You can use docker compose to start a development server, consisting of a test OctoPrint & Spoolman instances.

Note: the following steps have been tested on Linux-based OS. For Windows or MacOS - your mileage may vary.

Start the development server

docker compose up

Setup

On initial spin-up, you'll need to manually change permissions of the Spoolman directory:

# While in root directory of the project...
sudo chown 1000:1000 ./docker-data/spoolman

On first setup, you should configure your test Octoprint & Spoolman instances.

For Octoprint, there's currently no backup & restore method (problems with dockerized Octoprint not allowing to restore from backup), so you'll have to configure your instance manually (once).

For Spoolman, there's currently no backup & restore method, so you'll have to create spools manually.

Development

You can use docker compose to start a development server, consisting of a test OctoPrint & Spoolman instances.

docker compose up

App locations

• Octoprint should be available at localhost:7180.
• Spoolman (outside of Docker) should be available at localhost:7181.
• Spoolman (inside Docker) should be available at http://spoolman:8000.
  • This is the value you should paste into Spoolman plugin's settings in Octoprint.
• Data used by Docker containers is stored in docker-data folder.

Protips

• After applying any changes to the plugin's code, restart the Octoprint server so that it picks up your changes.
• You can place Octoprint's code in octoprint_Spoolman/octoprint directory.
  • This helps with some autocompletions, mostly in places where we're using Octoprint's shared APIs.
  • Don't worry about polluting git repo - this folder has been added to .gitignore already.

Distributing

Zip folder method (manual)

zip -r octoprint-spoolman.zip octoprint-spoolman -x "**/.git/*" "**/docker-data/*" "**/octoprint_Spoolman/octoprint/**" "**/__pycache__/*"
