AI repository intelligence
FR-AI / ANALYSISWhy it is worth attention
Offers a complete, transparent workflow with coach/expert modes, confidence scores, and no backend – all data stays in the browser.
Who it is for
- 3D printing enthusiasts who want precise filament profiles
- Users of Orca Slicer or Bambu Studio
- Makers who prefer step-by-step guidance without external resources
Use cases
- Calibrating a new filament for optimal print quality
- Creating a standardized profile for a specific printer-filament combination
- Rapidly setting up multiple spools with consistent settings
Strengths
- Guided workflow with coach mode and adaptive troubleshooting
- Fully transparent calculations showing inputs, formulas, and rounding
- Privacy-first: no account, no backend, all data locally stored
- Includes printer database with auto-filled specs for many models
Considerations
- No direct slicer preset file export (manual entry required)
- QR code links to hosted instance, does not embed data
- Photos are stored but not automatically analyzed
README quick start
PerfectFit — Filament Calibration Wizard
Create a perfectly calibrated filament profile for Orca Slicer or Bambu Studio in one guided workflow. No tutorials, no guesswork, no spreadsheets.
A local-first web app that walks you step by step through calibrating a filament profile for Orca Slicer (default) or Bambu Studio — temperature, flow ratio (two passes), pressure advance, retraction, max volumetric speed, and a final verification print — without tutorials, wikis, or guesswork.
- Coach Mode: plain-language guidance, good/bad examples, "I'm not sure" decision helpers, confidence checks, adaptive troubleshooting.
- Expert Mode: condensed flow — ranges, formulas, destinations.
- No black boxes: every calculation shows inputs, formula, substitution, and rounding.
- Signature features: calibration timeline, confidence score, smart retest recommendations, printable one-page calibration card with QR, printable full report, JSON backup/restore.
- Privacy: no account, no backend, no analytics/telemetry. Everything (photos included) stays in your browser's local storage. External model links open third-party sites.
Requirements
- Node.js 18+ (for development/build only — the built app is static files)
Install & run (development)
npm install
npm run dev # http://localhost:5173
Tests
npm test # vitest: formulas, ranges, numbering, margins, import/export, migration, validation
A human-workflow checklist lives in docs/MANUAL_TEST_CHECKLIST.md.
Production build
npm run build # typechecks, then bundles to dist/
npm run preview # serve the production bundle locally
dist/ is fully static and uses relative paths — it works from any folder or subpath.
Updating the Printer Database
The Add Printer screen lets users pick from a database of known printers, which auto-fills the machine specs (temperature limits, extruder type, build volume, supported nozzle sizes, chamber, firmware…). That database is generated from a human-editable spreadsheet and committed as JSON, so no build tooling or Excel is needed at runtime.
Source of truth: Printer_Database/Printer_Database.xlsx
→ worksheet Printer Specifications.
Runtime data: [src/data/printers.json](s
Description
A tool to calibrate filaments in both Orca Slicer and Bambu Studios. For beginners to experts.
