The Moment: automatic filament tracking and cost logging for PrusaLink printers
Hi all,
I received my CORE One L in May, a big step up from the Ender 3 V3 SE I was running via OctoPrint. I wanted to stay in the PrusaLink/PrusaConnect ecosystem rather than route everything through OctoPrint again, but PrusaConnect does not track filament consumption, does not log a print's cost in material and electricity, and its history only surfaces the last completed state; there is no searchable log across sessions. I missed all of that, so I forked FilaBridge and extended it into a tool that fills the gap for me. 81 prints in, I thought I would share in case it can help others.
The Moment sits alongside your PrusaLink printer and Spoolman. When a print finishes it:
- deducts the filament used from the right spool in Spoolman automatically, and if you forget to change it beforehand, allows retroactive spool reassignment.
- logs the print with a cost breakdown: filament, preheat electricity, print electricity, maintenance, and depreciation — with per-printer overrides if your printers draw different wattages
- saves the G-code thumbnail from the file into the history entry (PrusaSlicer and OrcaSlicer both embed them by default)
- Nothing to touch manually once a spool is assigned.
Confirmed on CORE One L. OctoPrint printers are also supported. Bambu MQTT support is in the codebase but has never been tested on real hardware.
Deploy if you have Docker (see the first-run guide):
curl -O https://raw.githubusercontent.com/ThetaSigmaLabs/the-moment/main/docker-compose.yml curl -O https://raw.githubusercontent.com/ThetaSigmaLabs/the-moment/main/.env.example && cp .env.example .env # edit .env to set your port and Spoolman URL if needed docker compose up -d
Spoolman is bundled in the compose file; you get both services together.
