PerfectFit v1.2.0

PerfectFit 1.2.0

A community-driven release — everything in it started as feedback from confuzled on the community Discord. Full notes: docs/RELEASE_NOTES_1.2.0.md in the repository.

Highlights

• Back up your slicer profiles BEFORE calibrating: a first-run prompt, a per-project prompt before any profile edits are suggested, and an on-demand button in Settings — all checksummed and restorable file-by-file from Settings → Slicer profile backups.
• New step — Flow Ratio Re-check (after Pressure Advance): PA changes what you judged in the flow test; the re-check confirms or corrects the saved ratio with one fine plate.
• New step — Shrinkage / Dimensional Accuracy: ap.engineering's free Printables calibration plate (spreadsheet scale-error entry or direct measurements), Vector3D's paid CaliFlower MK2, or any large measured object. Results flow into reports, cards, and generated profiles (filament_shrink).
• Honest drying advice: "fresh from a sealed bag" no longer counts as dry — PETG/TPU/PCTG often arrive wet from the factory; the checklist and material warnings now say so, with drying temperatures.
• Bambu Studio Develop Mode described accurately: the Preferences checkbox really is labeled "Develop Mode", and the calibration tests live under the title-bar Calibration button next to the Redo arrow (like all Orca-based slicers). All Bambu menu paths corrected.
• Each test names the profile to modify, with detected-preset suggestions when creating a project (desktop app).

Existing projects gain the two new steps as "not started" — progress and scores are preserved; both steps are skippable.

Downloads

• Windows: NSIS installer (.exe).
• macOS: universal Apple Silicon + Intel disk image (.dmg).
• Linux: Debian package (.deb) plus portable AppImage (.AppImage).

PerfectFit v1.1.5

PerfectFit 1.1.5

Patch release for the experimental Slicer Profile Installer. 1.1.4 fixed the
wizard so it recommends stock baselines — and thereby exposed the next bug:
profiles cloned from a stock preset were installed correctly but never
appeared in a signed-in Bambu Studio. Diagnosed by structurally comparing a
PerfectFit-installed preset against presets Bambu Studio 2.7.x itself writes
into the same account folder (H2S).

Fixes

Profiles cloned from stock presets now appear in Bambu Studio

Diagnosed by surveying every preset Bambu Studio 2.7.x itself had written
into a real signed-in account folder (70+) against the invisible
PerfectFit-installed ones, and matching the invariants exactly:

1. Stock-preset plumbing removed. Clones carried type,
   instantiation, and include — keys no Bambu-written user preset has.
   include is the worst: it references template files that don't resolve
   from a user folder. All three are stripped; everything they provided
   still flows through inherits.
2. filament_extruder_variant added. Every visible preset declares this
   legend mapping per-slot values to hardware (on an H2S:
   ["Direct Drive Standard","Direct Drive High Flow"]). Variant-aware
   Bambu Studio does not show user presets without it.
3. version stamped from the vendor manifest. Every visible preset
   carries the vendor library version from system/BBL.json (zero-stripped:
   02.07.00.08 → 2.7.0.8) — a value no preset inside the library
   declares. The native scan now reads vendor manifests to supply it.
4. Concrete inherits. Clones kept the stock leaf's own inherits
   (an abstract @base preset). Bambu saves user presets inheriting the
   concrete system preset by name; clones now do the same.
5. Fresh filament_id, always. The 1.1.3 fix only fired when the base
   declared an id — stock leaves inherit theirs, so clones of stock presets
   had none. Now always assigned; validation blocks missing/colliding ids.
6. Account user_id in the .info sidecar, stamped at install time
   (local, non-account installs stay empty), matching Bambu-written presets.

If a PerfectFit - … preset you installed earlier never showed up, reinstall
this build and re-run 🧵 Create Slicer Profile; installing under the same
name replaces the invisible file.

The wizard no longer calls the H2S a dual-nozzle printer

Bambu filament presets index per-slot arrays by (tool × hotend variant). On
single-nozzle printers with interchangeable hotends (H2S, P1S, …) the two
slots are the Standard and High Flow hotends — not two nozzles. The
"Multi-tool profile" step (now "Per-tool / per-hotend values") explains both
meanings and labels the slots, so calibrated values land in the slot matching
the hotend you actually calibrated with. Pick slot 1 for the Standard hotend,
slot 2 for High Flow.

Unchanged

Everything from 1.1.4 stands: the startup-hang fix (stale service worker),
recursive stock-preset scanning, inherited-metadata resolution, and the
stock-only baseline recommendations.

PerfectFit v1.1.4

PerfectFit 1.1.4

Patch release for the experimental Slicer Profile Installer. 1.1.3 promised
that baseline suggestions would be stock profiles compatible with the selected
printer, but on real Bambu Studio installs the fix was starved of data and the
wizard still fell back to user presets (reported with a Bambu Lab H2S). 1.1.4
fixes the three underlying defects, verified against a real Bambu Studio 2.7.x
install with an H2S.

Fixes

App no longer hangs on "Loading PerfectFit…" after an update

Updating (or uninstalling and reinstalling) could leave the app stuck on the
static loading screen. Cause: the PWA service worker was also registered
inside the Tauri desktop webview and cached index.html cache-first. After
an update it kept serving the previous version's HTML, which references a
hashed JS bundle that no longer exists — so the app never started. WebView2
profile data survives uninstall, which is why reinstalling didn't help.

Fixed in three layers: the desktop app no longer registers a service worker
(and unregisters any left behind by older versions); on Windows it removes
stale service-worker and HTTP-cache directories from the WebView2 profile at
startup, before the webview loads, which repairs installs already stuck; and
the service worker used by real web/PWA deployments is now network-first for
HTML so it can never pin an old shell again. Calibration data (IndexedDB /
localStorage) is not touched by any of this.

Stock baselines are now found and correctly matched

Three related defects, all diagnosed on a live install:

1. The system-library scan was not recursive. Bambu Studio keeps some
   vendor presets in subdirectories (e.g.
   system/BBL/filament/{P1P, Polymaker, SUNLU}/ — 150 presets on the dev
   machine), and the native scan only read the top-level folder. System scans
   now recurse (depth-limited).
2. Printer-specific stock leaves could not be material-matched. Presets
   like Bambu ABS @BBL H2S declare compatible_printers but inherit
   filament_type/filament_vendor from abstract parents, so the scanner saw
   them with no material: they scored below user presets and "qualified" for
   every material. The scanner now resolves inherited metadata through the
   system inheritance chain. The same resolution fills compatible_printers
   for user delta presets, which previously looked compatible with every
   printer and polluted fallback suggestions.
3. Recommendations now require an affirmative material match. Presets
   whose material remains unknown are no longer recommendable; they stay
   available under Advanced selection.

The scan is no longer silent when it fails

Wizard step 2 now shows a scan summary
(Scanned N preset(s): X stock · Y user · …) with an explicit warning when
zero stock presets arrive from the scan. If stock baselines are ever missing
again, the wizard says so instead of quietly suggesting user presets.

Changes

• The feature is now called "Create Slicer Profile" everywhere — the
  project-page button, the wizard page title, and the re-run button on the
  generated-profiles card all use the same name, matching the release notes
  and documentation (previously three different labels; see
  #10).
• Create Slicer Profile is reachable from the dashboard. Project cards
  show a 🧵 Create Slicer Profile button as soon as the project has at least
  one calibrated value — no need to open the project first.

Notes for existing users

• Reinstall this build, then re-run 🧵 Create Slicer Profile (dashboard
  card or project page). With a Bambu printer selected, step 2 should now
  recommend stock Bambu <material> @BBL <printer> (or Generic) baselines and
  show the scan-summary line.
• The 1.1.3 guidance for removing a cloud-stuck preset from a signed-in Bambu
  account still applies; see docs/RELEASE_NOTES_1.1.3.md.

Unchanged

Everything else from 1.1.0/1.1.3 stands: slicer detection, clone-and-patch
generation, validation, export, backup/restore, and verified direct install
for Orca Slicer, Bambu Studio, Snapmaker Orca, ElegooSlicer, and Flash Studio
on Windows.

PerfectFit v1.1.3

Changelog
1.1.4 - Unreleased

Small discoverability release prompted by #10: the 1.1.3 notes told users to "re-run Create Slicer Profile", but the feature went by three different names in the app and had no entry point on the dashboard, so it couldn't be found by that name.

Changed
The profile feature is now called "Create Slicer Profile" everywhere. The project-page button (previously "Create slicer profile"), the wizard page title (previously "Create and Install Filament Profile"), and the re-run button on the generated-profiles card (previously "Open profile wizard", now "Re-run Create Slicer Profile") all use the same name, matching the release notes and documentation.
Create Slicer Profile is now reachable from the dashboard. Project cards show a 🧵 Create Slicer Profile button as soon as the project has at least one calibrated value — no need to open the project first.
Clarified the 1.1.3 "Notes for existing users" in the changelog and release notes: the profile is regenerated in PerfectFit (project page → 🧵 Create Slicer Profile), not via Bambu Studio's "Create New" dialog, which does not know about PerfectFit calibration data.
1.1.3 - 2026-07-20

Patch release fixing two profile-installer bugs found while using the 1.1.0 build with Bambu Studio. See docs/RELEASE_NOTES_1.1.3.md.

Fixed
Installed Bambu profiles now appear in the slicer. In 1.1.0 a profile installed for a signed-in Bambu account was written correctly but never showed up in the filament list. Cause: when signed in, Bambu Studio dedupes filament presets by filament_id, so a clone that kept its parent's filament_id was hidden behind the cloud-synced parent it was cloned from. Confirmed directly in Bambu Studio 2.7.x — a copy with a fresh filament_id appears immediately; the colliding one never does. Fix: generated presets now get a fresh unique filament_id, and the .info base_id chains to the stock/system ancestor instead of a parent user preset's cloud id.
Baseline suggestions are now stock profiles compatible with the selected printer. In 1.1.0 the "select a base profile" step suggested the user's own custom presets (some flagged as incompatible with the printer). It now recommends only stock (system) profiles — brand-name or generic — for the calibrated material that are compatible with the selected printer. User and incompatible-printer presets remain available under Advanced selection.
Notes for existing users
Reinstall this build for the fixes to take effect (the fix applies to newly generated profiles).
A profile installed by 1.1.0 into a signed-in Bambu account is stuck in Bambu's cloud with the colliding id; editing local files won't unhide it. Remove it in Bambu Studio: select the preset, open it for editing (the edit/pencil icon opens the Filament settings dialog), and click the small 'X' (delete) icon in the upper-right of that edit dialog — this removes it from your cloud sync. Then regenerate the profile in PerfectFit (not Bambu Studio): open your calibration project from the PerfectFit dashboard and click 🧵 Create Slicer Profile on the project page, then follow the wizard through to install/export. Your calibration data is preserved in PerfectFit, so no re-calibration is needed.

PerfectFit v1.1.0

PerfectFit 1.1.0

PerfectFit 1.1.0 adds Linux desktop packages alongside the existing Windows and macOS release assets, and rolls up the slicer profile installer work, Bambu Studio Developer mode calibration guidance, documentation improvements, and project-health updates completed since 1.0.0.

Downloads

• Windows: NSIS installer (.exe).
• macOS: universal Apple Silicon + Intel disk image (.dmg).
• Linux: Debian package (.deb) plus portable AppImage (.AppImage) for broad distro coverage.

Highlights since 1.0.0

• Added experimental slicer profile generation and direct install workflows for Orca Slicer, Bambu Studio, Snapmaker Orca, ElegooSlicer, and Flash Studio Desktop. ***These are experimental and I've been having mixed results.
• Added transactional backups, restore support, diff previews, profile compatibility scoring, and validation so generated profiles only patch values backed by completed calibration steps.
• Verified Windows direct-install flows against real slicer account directories for Orca Slicer and Bambu Studio, including Bambu dual-nozzle array preservation.
• Updated Bambu Studio coached wizard pages to recommend Developer mode as the best way to access manual calibration tests while a Bambu printer remains selected.
• Documented Bambu Developer mode availability for Temperature, Flow Rate coarse/fine (no YOLO), Pressure Advance / Flow Dynamics, Retraction, Max Flow Rate, and VFA.
• Added Linux release packaging via .deb and AppImage artifacts.
• Added issue templates, contribution guidance, security policy, code of conduct, pull request template, and expanded automated coverage.

Known limitations

• Linux native slicer profile detection/install behavior is not yet claimed as verified; Linux packages are provided so users can run the desktop app and use browser-equivalent/export workflows while native Linux slicer integration is validated.
• macOS native slicer path detection remains documented but not fully real-machine verified.
• Cloud-synchronized Orca/Bambu account directories may later sync, duplicate, re-id, or remove local preset files; PerfectFit surfaces this caveat and keeps backups for installed profiles.
• VFA is mentioned where Bambu Developer mode exposes it, but PerfectFit does not currently have a dedicated VFA scoring step.
