Spoolman is a self-hosted web service designed to help you efficiently manage your 3D printer filament spools and monitor their usage. It acts as a centralized database that seamlessly integrates with popular 3D printing software like OctoPrint and Klipper/Moonraker. When connected, it automatically updates spool weights as printing progresses, giving you real-time insights into filament usage.
I just discovered Spoolman the other day by pure accident. Read about it quickly in a comment on some social media platform and instantly had to look it up. It looks pretty sweet. In the past I have never really needed much organization for my filament. I only had a few rolls of a few colors and did not print very heavily. Since getting the Elegoo Neptune 4 Max I have dumped rolls into the printer. I now find myself with a bunch of half used rolls of filament and if I want to use them I have to eyeball how much is left. Yes my spools have meter and gram indicators but that’s still a rough guess. Spoolman takes the guesswork out of it all.
If you have a printer running Klipper you can probably install and use Spoolman. If you have a printer like an Elegoo Neptune 4 with Klipper – you can’t. Elegoo did something to the firmware that makes it so you cannot update with the current versions out there. Nor can you update the boards OS without breaking things I have read. Moonraker needs to be updated to use Spoolman. There is a procedure I have found for updating Moonraker on the Neptune but I HAVE NOT TRIED IT. I posted it over here on my other post but I will reference it here also. This was my push to install OpenNept4une.
This is my guide/what I did to get Spoolman on my Neptune 4 Max with OpenNept4une.
