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. In this step by step guide I will show you how to install Spoolman on your UGREEN NAS using Docker & Portainer.

💡Note: This guide works perfectly with the latest Spoolman v0.22.1 release.

🟢Please Support My work by Making a Donation. Almost 99,9% of the people that install something using my guides forget to support my work, or just ignore STEP 1. I’ve been very honest about this aspect of my work since the beginning: I don’t run any ADS, I don’t require subscriptions, paid or otherwise, I don’t collect IPs, emails, and I don’t have any referral links from Amazon or other merchants. I also don’t have any POP-UPs or COOKIES. I have repeatedly been told over the years how much I have contributed to the community. It’s something I love doing and have been honest about my passion since the beginning. But I also Need The Community to Support me Back to be able to continue doing this work.

• STEP 10

The installation process can take up to a few seconds/minutes. It will depend on your Internet speed connection. Now open your browser and type in http://ugreen-ip-address:7912 Follow the instructions in the image below.
