Sliced files previewed through a vendored copy of PrettyGCode in an
iframe. It drew each move as a screen-space line -- a line has no
thickness in the scene, so it cannot occlude the layer behind it, which
is why prints came out stringy and shimmered where layers crossed. Being
a separate app in a frame, it could be neither themed nor translated, and
carried its own machinery for detecting a proxy refusing the embed.
Now built on libvgcode, the renderer OrcaSlicer draws its own preview
with, vendored from three-slicer (AGPL, same as us). It takes the THREE
namespace as an argument and imports nothing, so it runs on our 0.181
rather than the 0.160 its package pins.
The parser is ours; upstream renders its own kernel's output and ships no
G-code parser at all. Two things it has to get right, both found by
checking a real plate rather than assuming:
- BambuStudio does not use the OrcaSlicer/PrusaSlicer annotations. It
writes "; FEATURE:", "; LINE_WIDTH:", "; CHANGE_LAYER" and
"; Z_HEIGHT:", not ";TYPE:", ";WIDTH:" and ";LAYER_CHANGE". Reading
only the latter showed a 52-layer print as 23,165 layers in one colour,
because with no layer marker recognised every travel Z-hop split a
layer and every segment took the fallback feature.
- It emits a tenth of its moves as G2/G3 arcs -- 706 extruding ones in a
single plate. Ignoring them punched holes through curved walls and tree
supports. Arcs with no X/Y are the helical travel lift and lay down
nothing, so they interpolate as travels.
Four colour modes: filament (default, from the AMS slots the file was
sliced with), feature, layer height, line width. Speed, fan and
temperature are deliberately absent -- upstream derives those from
settings rather than the toolpath, and guesses dressed as measurements
are worse than an honest omission. The parser now carries the data to do
them properly later.
Legend entries are switches. Hiding removes the records before the mesh
is built rather than recolouring them: the shader packs colour into a
single float with no alpha, so there is no transparent to set, and
removal is the useful behaviour anyway -- a hidden support stops
occluding what it covered.
The scene is built once and only the toolpath rebuilds. Doing otherwise
constructed a new WebGLRenderer on every render, because the buildVolume
default is an object literal and so a fresh identity each time; browsers
cap live WebGL contexts and drop the oldest, which blanked the canvas
after a few interactions.
utils/framing.ts goes with the iframe, along with six now-orphaned
strings in all 13 locales. src/lib/vendor is excluded from eslint --
acting on findings in vendored code makes it impossible to re-copy on the
next upstream release.
Reshapes the embedded PrettyGCode viewer (landed in #963) into a focused
archive-preview tool, matching Bambuddy's data model instead of the
OctoPrint-style "connected-printer + library file picker" flow it shipped
with. Reached only from the Archives page 3D-preview button; URL
/gcode-viewer?archive=<id>[&plate=<N>].
Backend:
- /archives/{id}/gcode accepts ?plate=N and resolves the filename by
parsing the suffix as int, so zero-padded names like plate_01.gcode
are found when the plates endpoint reports index 1.
- /archives/{id}/plates gains top-level has_gcode: bool. Source-only
3MFs (PNG/JSON fallback path) surface the flag so the frontend can
skip the picker instead of sending the user into a dead viewer.
- printer_state_to_dict injects name + model into every WS snapshot so
consumers render proper labels on the initial tick without racing a
separate /printers fetch.
- /gcode-viewer (no trailing slash) dropped from the backend so reloads
fall through to the SPA catch-all and keep the layout shell; only
/gcode-viewer/ (trailing slash) and /gcode-viewer/<path> remain for
the iframe + static assets.
Frontend:
- PlatePickerModal shown only for multi-plate archives with sliced
gcode, grid layout with thumbnails matching the Re-print modal.
- Source-only archives show a noGcode toast instead of the empty
viewer.
- ArchivesPage navigate path swapped to /gcode-viewer?archive=<id> with
no trailing slash; GCodeViewerPage iframe forwards
window.location.search so the archive reference survives both the
initial navigate and a full-page reload.
- Viewer iframe's auth path: fetch intercept injects Bearer; a 401
redirects to / so the SPA handles login.
Viewer adapter:
- Stripped the printer selector, WebSocket subscription, library file
picker, tryAutoLoadPrintingFile, BAMBU_BED_SIZES, and updatePrinter-
Selector. The viewer no longer observes live printer state.
- Bed size derived from /archives/{id}/capabilities.build_volume
(extracted from the 3MF's printable_area/printable_height), so H2D,
H-family, and any future printer render on the correct bed without
a hardcoded map.
- loadArchiveById accepts a plate param; fetch intercept rewrites
__bambuddy_archive_<id>[_plate<N>] to /archives/<id>/gcode[?plate=N].
Nav + locale cleanup:
- Sidebar "GCode Viewer" nav entry removed (viewer is archive-scoped
now, not a destination page).
- 32 orphaned gcodeViewer locale keys deleted across all 8 locales.
- platePicker.{title, hint, plateLabel, objectCount, noGcode} keys
added in all 8 locales.
ArchivesPage: the now-unreachable ModelViewerModal render paths + its
showViewer state removed. ModelViewerModal itself stays — File Manager
still uses it for library file previews (plate picker + .3mf 3D model).
pre-commit:
- gcode_viewer/ excluded from trailing-whitespace + end-of-file-fixer
so vendored third-party JS libs don't drift away from upstream.
Incidental sweeps picked up by pre-commit and kept (unrelated but
benign):
- NotificationsPage.tsx: single trailing-whitespace line removed.
- spoolbuddy/scripts/pn5180_diag.py: dead `import gpiod` dropped —
the pn5180 driver module imported at line 27 does its own
`import gpiod` and `gpiod.Chip()` calls, so the diag script's
top-level import was never referenced.
Tests:
- 6 new cases in test_gcode_viewer.py for the backend plate / has_gcode
behaviour (plate=N resolution, zero-padded filenames, missing-plate
404, no-plate fallback, plate=0 rejection, has_gcode true/false).
- 3 new cases in test_printer_manager.py for name/model WS injection.
- PlatePickerModal.test.tsx — 6 frontend cases covering render,
plate-name composition, onSelect payload, backdrop close, and
thumbnail fallback.
The log sanitizer only used regex patterns, missing arbitrary user-chosen
strings (printer names, usernames). Tasmota smart plug credentials were
logged verbatim in URLs by httpx.
- Make _sanitize_log_content() database-aware: query Printer names/serials,
User usernames, and Bambu Cloud email for exact-string replacement
(longest-first, skip <3 chars to prevent over-redaction)
- Fix serial regex leaking first 3 chars (remove capture group partial
redaction), add case-insensitive flag
- Move Tasmota credentials from URL-embedded (http://user:pass@host) to
httpx auth= parameter so they never appear in logs
- Add URL credentials regex as defense-in-depth for user:pass@ in logs
- Add 'username' and 'path' to settings sensitive_keys filter (catches
smtp_username, slicer_binary_path in support-info.json)
Add frontend-typecheck (tsc --noEmit) and frontend-lint (eslint .)
hooks to .pre-commit-config.yaml. Both hooks only trigger when
frontend/src/**/*.{ts,tsx} files are staged.
- Add "Recalculate Costs" button to Dashboard that updates all archive
costs using current filament prices (Issue #120)
- Track reprints and add cost to existing archive total on completion,
so statistics accurately reflect total filament expenditure
Closes#120
prints (not just completed), matching get_printer_total_hours behavior
- Add option to keep or delete archives when deleting a printer
- Custom maintenance types no longer auto-assign to all printers
- Add UI to manually assign/remove custom maintenance types per printer
- Add backend endpoints for assigning types to printers and removing items
- Exclude static/assets from large file pre-commit check
