From d4ad41d850069ad9d7c51a9b425c3f6606292457 Mon Sep 17 00:00:00 2001 From: maziggy Date: Sat, 27 Jun 2026 09:18:57 +0200 Subject: [PATCH 1/2] fix(hms): action buttons actually reach the printer (#1830) Three distinct bugs combined into one user-facing failure: clicking Stop / Problem-solved-and-resume / Ignore-and-resume returned 200 OK but the printer didn't act, modal stayed up, print stayed paused. Verified by injecting candidate command shapes on device//request against a live H2D paused on a wrong-plate HMS (print_error=0x05008051). (1) hms_resume / hms_stop dispatched the "err"-bearing shape that BambuStudio doesn't actually send; Bambu firmware silently rejects it. Both now send the plain shape ({"print":{"command":"","param":"", "sequence_id":"0"}}). PAUSE -> FAILED in 1.7s for stop, PAUSE -> RUNNING in <2s for resume. (2) IGNORE_RESUME mapped to idle_ignore, which is BambuStudio's "dismiss a warning" command and only works for non-pause warnings. hms_ignore now branches on state.state == "PAUSE": paused -> plain resume; not-paused -> idle_ignore with the full-length err. (3) 64-bit hms[]-array faults were truncated to a non-matching err. short_code in _parse_status discarded 32 of the 64 identifier bits, so the firmware didn't match it to the active fault. HMSError.full_code now carries the canonical hex identifier (16 chars for hms[] faults, 8 chars for print_error faults). Catalog lookup tries 16-char first, falls back to 8-char. HmsActionBody.print_error pattern relaxed to ^[0-9A-Fa-f]{8}([0-9A-Fa-f]{8})?$. (4) execute_hms_action returned publish-success as success, masking every silent-rejection bug above as 200 OK. Route now snapshots (state.state, len(state.hms_errors)) before dispatch, awaits HMS_ACTION_ACK_WAIT_SECONDS (default 2.5s, module-level so tests override), and returns 502 with "Printer did not acknowledge HMS action within 2.5s" if state didn't move. --- CHANGELOG.md | 3 + backend/app/api/routes/printers.py | 42 +++++++- backend/app/schemas/printer.py | 15 ++- backend/app/services/bambu_mqtt.py | 69 ++++++++++--- backend/app/services/printer_manager.py | 1 + .../tests/integration/test_printers_api.py | 96 +++++++++++++++++-- .../tests/unit/services/test_bambu_mqtt.py | 77 +++++++++++++++ .../tests/unit/services/test_hms_actions.py | 75 ++++++++++++--- frontend/src/api/client.ts | 5 + frontend/src/components/HMSErrorModal.tsx | 7 +- .../{index-WvBaLL5O.js => index-CfzVLrcT.js} | 2 +- static/index.html | 2 +- 12 files changed, 355 insertions(+), 39 deletions(-) rename static/assets/{index-WvBaLL5O.js => index-CfzVLrcT.js} (98%) diff --git a/CHANGELOG.md b/CHANGELOG.md index 56443a5e4..d35fd4507 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -4,6 +4,9 @@ All notable changes to Bambuddy will be documented in this file. ## [0.2.5b1] - Unreleased +### Fixed +- **HMS Action buttons now reach the printer (#1830, H2D/H2C wrong-plate verification)** — The HMS Actions feature shipped in #1743 looked correct at the publish layer but the firmware silently dropped the commands at the printer, so clicking "Stop printing", "Problem solved and resume", or "Ignore and resume" did nothing visible on the live H2D — the modal kept reappearing, the print stayed paused, and the route still returned `200 OK`. Three independent bugs combined into one user-facing failure. **(1) Wrong command shape for resume / stop.** `hms_resume()` and `hms_stop()` sent the documented-but-not-actually-used `{"err": , "param": "reserve", "job_id": , ...}` shape that BambuStudio never produces. Bambu firmware rejects this silently — verified by injecting candidate shapes on `device//request` against a live H2D paused on a wrong-plate HMS: the `err`-bearing shape held PAUSE → PAUSE for the full window, the plain `{"print":{"command":"stop","param":"","sequence_id":"0"}}` transitioned PAUSE → FAILED in 1.7s, the same plain `resume` transitioned PAUSE → RUNNING in <2s. Fix: both helpers send the plain shape now, no `err`, no `job_id`, no `param:"reserve"`. **(2) `IGNORE_RESUME` mapped to the wrong command for paused prints.** The original mapping dispatched `idle_ignore` for both `IGNORE_RESUME` and `NO_REMINDER_NEXT_TIME`. `idle_ignore` is BambuStudio's "dismiss this warning" command and only works for non-pause warnings — verified against the H2D, idle_ignore on a paused print is silently rejected regardless of `err`. `hms_ignore()` now branches on `self.state.gcode_state == "PAUSE"`: paused → dispatch plain `resume` (which is what the button actually means on a paused print), running/idle → keep `idle_ignore` with the `type=0/1` persistence flag. `DONT_REMIND_NEXT_TIME` on PAUSE degrades to resume too — the "don't remind" flag can't ride along on a resume but the user's clicked-action intent (continue printing) is honoured. **(3) 64-bit `hms[]`-array faults truncated to a non-matching `err` (#1830 §(1)).** The hms[] parser at line 2740 built the short code as `f"{(attr >> 16) & 0xFFFF:04X}_{code & 0xFFFF:04X}"`, discarding 32 of the 64 bits of the fault identifier. For codes whose full form is e.g. `0C00_0300_0002_000C`, the truncated `0C00000C` doesn't match what the firmware compares against in `idle_ignore`. New `HMSError.full_code` field carries the canonical hex identifier — 16 chars `f"{attr:08X}{code:08X}"` for hms[]-sourced faults, 8 chars `f"{print_error:08X}"` for print_error-sourced faults (which are already 32-bit). Catalog lookup tries the 16-char form first and falls back to the 8-char short code so existing entries keep matching. Frontend echoes `error.full_code` back as `HmsActionBody.print_error` instead of recomputing the short code; the schema's pattern relaxes to `^[0-9A-Fa-f]{8}([0-9A-Fa-f]{8})?$` to accept both lengths. **(4) Masking failure — publish-success returned as printer-ack (#1830 §(3)).** `execute_hms_action` returned True the moment the publish succeeded, so any of the three bugs above produced `200 OK` while the printer ignored the command and the modal kept popping. The `/hms/execute-action` route now snapshots `(gcode_state, print_error, hms_errors count)` before dispatch, awaits `HMS_ACTION_ACK_WAIT_SECONDS` (default 2.5s, module-level so tests override), and returns `502 "Printer did not acknowledge HMS action within 2.5s"` if none of those moved. Every accepted HMS action mutates at least one of the three, so this is a clean signal. **Empirical verification.** A test harness on `device/0948BB540200427/request` confirmed each shape against the live H2D: a print sent with deliberately-wrong build plate raises `print_error=0x05008051` ("Detected build plate is not the same as the Gcode file"), the printer enters `gcode_state=PAUSE`, and the new command shapes transition out correctly. The current Bambuddy code (before this fix) failed to act on every button. **Tests.** `test_hms_actions.py` shape assertions rewritten — `test_resume_is_plain_no_err_no_job_id`, `test_stop_is_plain_no_err_no_job_id`, `test_ignore_resume_dispatches_resume_when_print_paused`, `test_ignore_resume_uses_idle_ignore_when_not_paused`, `test_dont_remind_dispatches_resume_when_paused`, `test_dont_remind_uses_idle_ignore_type_one_when_not_paused`, `test_idle_ignore_accepts_16_char_full_code`. New `TestHMSFullCode` class in `test_bambu_mqtt.py` pins the parser contract — `test_hms_array_path_populates_16_char_full_code`, `test_print_error_path_populates_8_char_full_code`, `test_hms_array_catalog_lookup_tries_16_char_first`, `test_hms_array_catalog_falls_back_to_8_char`. New integration cases in `test_printers_api.py` — `test_execute_hms_action_no_printer_ack_returns_502`, `test_execute_hms_action_accepts_16_char_full_code`. The malformed-input test now covers 9- and 15-char rejections (the relaxed pattern accepts 8 OR 16, nothing in between). `pytest -n 30 backend/tests/unit/services/test_hms_actions.py backend/tests/unit/services/test_bambu_mqtt.py backend/tests/unit/services/test_printer_manager.py backend/tests/integration/test_printers_api.py` green (509 + 181). `ruff check` clean. Frontend `npm run build` clean. **Scope.** No DB migration. No new permission. No new i18n key — the frontend toast on action failure already uses the existing `hmsErrors.actionFailed` string, which now gets the more accurate "Printer did not acknowledge" message instead of "Failed to send action". The `HMSError.full_code` field defaults to `""` so old in-memory state surviving a backend upgrade (without an MQTT reconnect) degrades to the existing 8-char short code via the frontend's `||` fallback. + ### Added - **Sponsor-prompt thresholds lowered to fire for typical new installs** — The in-app sponsor toast in `useSponsorPrompt` was calibrated for power users: the lowest print milestone was `100`, the lowest archive milestone was `50`, the lowest filament-cost milestone was `100`. A check of recent Matomo data showed the toast firing very rarely (`?from=app-toast-prints-100` = 4 visits, `?from=app-toast-archives-50` = 3 visits in a 7-day window) — most installs simply never reach those bars, especially with the install base ~doubling since March. Calibration widened: `PRINT_MILESTONES` now `(10, 25, 100, 500, 1000, 2500, 5000)`, `ARCHIVE_MILESTONES` now `(5, 10, 50, 250, 1000)`, `COST_MILESTONES` now `(25, 50, 100, 500, 1000)`. The existing priority order (anniversary → prints → archives → cost → version-update) and 14-day cross-family cooldown are unchanged, so a user still sees at most one toast per fortnight. The "fire highest unseen milestone" logic in `_check_prints` / `_check_archives` / `_check_cost` is unchanged — a user already at 200 prints still gets `prints-100` first (they crossed it earlier in the timeline). The existing toast copy uses `{count}` / `{total}` interpolation in all 11 locales — no new i18n keys needed; "You've completed 10 prints with Bambuddy" reads as fluently as the 100 variant. **Tests.** `test_failed_prints_dont_count` and `test_fires_when_cost_sum_crosses_100` rebalanced (5 completed prints instead of 50; 5 prints × 21 cost-each instead of 30 × 3.5) so they still test "below the lowest threshold" semantics with the new lower bars. New `test_fires_at_lowest_threshold` pins `prints-10` as the new minimum trigger. `pytest -n 30 backend/tests/unit/test_sponsor_prompt_service.py backend/tests/integration/test_sponsor_prompt_api.py` green (25/25). `ruff check` clean. **Scope.** No DB migration. No new permission. No frontend change. The change is opt-in by virtue of the existing toast cooldown — installs that already saw a recent toast see no behaviour change; installs that never crossed the old 100-print bar become eligible the first time they pass 10 prints (subject to the 14-day cooldown after any other family fires first). diff --git a/backend/app/api/routes/printers.py b/backend/app/api/routes/printers.py index 5a7053f4d..646bd94d6 100644 --- a/backend/app/api/routes/printers.py +++ b/backend/app/api/routes/printers.py @@ -63,6 +63,11 @@ from backend.app.utils.http import build_content_disposition logger = logging.getLogger(__name__) router = APIRouter(prefix="/printers", tags=["printers"]) +# Seconds the /hms/execute-action route waits for a printer status push +# confirming the command landed before reporting 502 to the UI.
