FAQ - Frequently Asked Questions

What is Spoolytracker?

Spoolytracker is a comprehensive filament management platform for 3D printing. It allows you to track your stock to the gram, analyze GCode files to estimate costs and consumption, and manage your printing projects from start to finish.

Is the service free?

Yes, Spoolytracker offers a generous free plan that allows you to manage up to 30 spools with analytics included. For heavy users or professionals, Pro and Enterprise plans offer more spools, more projects, and priority GCode scan queues.

How does NFC tracking (TigerTags) work?

You can attach NFC chips (called TigerTags) to your spools. Using our mobile app, you simply scan the spool to instantly identify it, see its remaining stock, and deduct consumption after a print.

Which printers are compatible?

Spoolytracker is compatible with all FDM 3D printers. You can upload your GCode (Cura, PrusaSlicer, OrcaSlicer, etc.) for automatic analysis, or enter your consumption manually.

How do I connect OrcaSlicer to Spoolytracker?

1

Generate a key

Settings > Integrations, then create an OrcaSlicer key.

2

Download the script

Available from Settings > Downloads.

3

Paste the command

In OrcaSlicer: Prepare > Process > Others.

Example command

python "C:\path\to\spooly_orca.py" --api-url https://app.spoolytracker.com --api-key sk_orca_xxx --commit

Without --commit, the script only analyzes the G-code. With --commit, it also records consumption on the suggested spool.

How do I connect Home Assistant to SpoolyTracker?

The Home Assistant integration connects SpoolyTracker with an API key, then lets your automations record filament consumption automatically.

1

Add the HACS repo

HACS > menu > Custom repositories, add the SpoolyTracker repo, category Integration.

2

Install SpoolyTracker

Install the integration from HACS, then restart Home Assistant.

3

Add the integration

Settings > Devices & services > Add integration > SpoolyTracker.

Recommended configuration

Choose Cloud for the official https://api.spoolytracker.com service.
Choose Other for a self-hosted instance, entering the base URL without /public-api/v1.
Generate a SpoolyTracker key with filaments:read, stock:read, consumption:read, consumption:write and analytics:read scopes.

Service example

action: spoolytracker.log_consumption
data:
  printer_name: "Workshop"
  grams_used: 42
  ams_unit: 1
  ams_slot: 0

The integration can identify the spool by spool_id, AMS mapping, active spool select or metadata. If the spool is ambiguous, it refuses to log silently and emits a resolution event.

Is my data secure?

Absolutely. Your data is hosted on secure servers in Europe. We use industry-standard encryption to protect your personal information and production data.

Can I use Spoolytracker without an internet connection?

The web app requires a connection. However, the mobile app allows you to view some information, and we are working on an offline mode for NFC scans in the workshop.

How does the AI assistant help me?

Spool AI is a real copilot for your workshop. It understands plain-language questions and acts on your data (always asking for confirmation before writing anything):

Natural-language inventory — "Which red filament is the fullest?", "How much PETG do I have left?"
Run-out forecasting — estimates when you'll run out and builds a restock list sorted by urgency.
Project feasibility — "Do I have enough material for this part?" with a per-spool breakdown.
Consumption logging — the AI offers to deduct used weight from the right spool, changing nothing until you confirm.
Calibration assistant — describe your test print (temperature tower, flow, VFA…) and the AI computes the right settings, then applies them straight to your filament.

Available free for everyday questions, and in Pro for advanced actions and the calibration assistant.

What are the calibration editors / calculators for?

SpoolyTracker ships calibration calculators right inside each spool (web and mobile). Run a test print, read the result, and the calculator turns it into ready-to-use settings:

Max volumetric flow — from the flow test, so you stop under-extruding at high speed.
Flow ratio — for walls with accurate dimensions.
Max speed by temperature (VFA) — spot the notch where it breaks down; the calculator derives the maximum speed and adds a conditional temperature rule (max speed + temperature) to your filament.
Pressure advance, retraction, temperature tower…

A dedicated button opens the calculators from any inventory row, with a reminder of the spool being calibrated. Once confirmed, the value is written to the filament (with confirmation if it replaces an existing setting) and flows into your exported profiles.

How do I import a filament config into Bambu Studio or OrcaSlicer?

Every spool can be exported as a JSON filament profile that imports straight into OrcaSlicer and Bambu Studio — temperatures, flow, speeds, retraction and conditional rules included.

1

Export from SpoolyTracker

In the inventory, use the "Export profile" button (JSON icon) on the spool.

2

Import into the slicer

Filament tab > import icon, pick the .json file.

3

Print

The profile shows up in your filament list, ready to go.

The profile is generated in the format Orca/Bambu expect (type: filament, compatible with every printer) for an error-free import. Calibrate once in SpoolyTracker, reuse everywhere.
