Release notes

What changed in each version of OpenTag Station, newest first.

1.0.1-beta.6

Pre-release for testers. One new setting. Not run on a WT32 by the author; see "Needs a station".

Display - The screen can be turned upside down. Browser: Settings → Display → Screen orientation, Normal or Upside down (turned 180°). The touchscreen, including touch, turns at once and keeps the orientation after a restart. Settings key device.display_rotation, 0 or 180; GET /api/v1/config reports it and PATCH /api/v1/config accepts it under device. Any other value is refused. Older saved settings without the key mean 0.

Needs a station - Set the orientation to upside down in the browser and check that the screen turns without a restart, that touches land where they are shown (tap each of the five pages), that the setting survives a reboot, and that Normal turns it back.

1.0.1-beta.5

Pre-release for testers. First step of the tag-support roadmap (#93): the reader now also looks for ISO 14443A (NFC-A) tags and names them. Nothing is read from them yet. Not run on a WT32 by the author; see "Needs a station" below.

NFC - NTAG, MIFARE and other NFC-A tags are found and named. Each poll cycle still asks for NFC-V (ISO 15693) tags first, exactly as before. Only when that finds nothing, and no NFC-V tag is being tracked, does the same cycle also run an ISO 14443A detection (REQA and anticollision). So an OpenPrintTag is found and lost on the same polls as in 1.0.1-beta.4; the only added cost is one short NFC-A request on cycles with no NFC-V tag. - An NFC-A tag is reported with its NFCID1, SAK and ATQA and a kind derived from the SAK (NXP AN10833): type2 (NTAG, MIFARE Ultralight), mifare_classic, type4 or other. Nothing on the tag is read, it is not looked up in Spoolman, and the automatic weigh does not start for it. - Touchscreen: Home shows "TAG FOUND" / "Tag type not supported yet" with the kind; the Tag page shows the kind and the ID; the NFC READER setup step says "Tag found. Its type is not supported yet." Browser: the Dashboard shows "Tag type not supported yet" / "Not supported yet", Manage tag names the kind, and "Multiple NFC-A tags detected" when there are several. - API: GET /api/v1/nfc gains technology (nfcv, nfca or null) and, for an NFC-A tag, the state unsupported_technology, lifecycle UNSUPPORTED_TYPE, the NFCID1 as uid and an nfca object (nfcid1, length, sak, atqa, kind, description). inventory.technology now names the technology of the tag on the reader. - The serial diagnostic line adds technology= and, for an NFC-A tag, its NFCID1, SAK, ATQA and kind. - The production NFC check (tools/check_production_nfc.py) permits exactly three NFC-A RFAL calls (mode switch, technology detection, collision resolution) in the I2C driver only, and the ELF check now also fails if a Type 2 read or write, ISO-DEP or NFC-DEP routine is linked.

Needs a station - Detection and removal timing of an OpenPrintTag before and after this change, and the detection of an NTAG and a MIFARE Classic tag, have not been measured by the author. The acceptance steps are in the pull request for this release and in issue #93.

1.0.1-beta.4

Pre-release for testers. The Community catalog is gone, and the leftovers from the 1.1 cleanup list that needed screenshots or a station are done. Nothing in this list has been run on a WT32 yet; see "Needs a station" below.

Removed - The Community filament catalog is deleted (#86). It was disabled since 1.0.0-rc.9 and never part of a release. Gone with it: the catalog service, its download and gzip decoder, the writer's import actions (community_*, import_preview, import), the browser's "Find in Community" source and Settings card, the touchscreen's Community choice, the OPENTAG_ENABLE_COMMUNITY switch, the native-community test environment and the 2.4 MB community/community.pack. The writer now rejects those actions as unknown. The factory image still erases the filesystem (its part is now called factory-littlefs.bin and must be empty), and a factory reset also deletes /community.pack, /community.new and /community.old that a station flashed before 1.0.0-rc.9 may still hold. - POST /api/v1/nfc/read is removed. It always answered 503: the reader reads a tag when it is placed. Use GET /api/v1/nfc. - Test-only settings code (export_json, import_json, clear_spool_identity_mapping) is removed together with its tests.

Touchscreen - The Home WEIGH button only weighs. It no longer turns into CALIBRATE or WRITE TAG. It is disabled until the scale is calibrated, and the weight line then says "Scale not calibrated"; calibration lives on the Weigh page, writing a blank tag under Manage tag. - The tag review shows the writer's other warnings: an interrupted write that this write completes, optional data not set in Spoolman ("Optional data not set: gtin, manufactured date and 2 more"), and any other note the writer adds. Fields that will not be written were already listed. - Choosing a spool on the "Which spool is this?" page now shows "Linked to spool #N" under the tag until Spoolman confirms the link. A refused choice says the station is busy. - If the settings storage cannot be read, the Home screen says so and tells you to reinstall the firmware with the USB installer; the browser shows the same message from /health.

Robustness - Tag writes and weight saves are refused while a restart is pending (a reboot, factory reset, firmware update or the health check of new firmware). This covers the automatic weight save after a weigh. Only the catalog search stays available. The answer is "The station is restarting, resetting or checking new firmware. Try again after it has restarted." - A reset marker with an unreadable filesystem no longer reboots in a loop. The station stays up with storage failing closed and reports the problem instead of restarting into the same recovery. - Skipping a recovery names the tag. discard_recovery now needs the tag's UID and is refused for another tag ("This recovery belongs to tag ..."). The browser's clear dialog ends in "Recovery skipped" with a Done button. - wifi.auto_reconnect: false now opens the setup network after the first failed connection. Before, the station stopped trying but never opened it, because the failure count it waits for could not be reached.

Docs - The toolhead profile fields nozzle_material and maximum_temperature_c are stored for a future compatibility check and have no visible effect yet.

Needs a station - Everything above is covered by host tests and CI only. In particular: the refusal while a restart is pending, the behaviour with an unreadable filesystem, the setup network with auto_reconnect: false, and the Home button and tag review wording on the real screen.

1.0.1-beta.3

Pre-release for testers. Reliability fixes for rare cases; nothing changes in normal use.

  • Settings survive a power cut during recovery. If the main settings file was damaged and the station restored them from its backup, saving the restored copy replaced the only good backup first. A power cut at that moment lost the settings. Recovery now writes the main file and leaves the backup alone.
  • Clearing a tag works when Spoolman holds the spool's UUID in capitals. The tag carries the UUID in lower case, so the station refused to unlink with "Owner instance UUID changed". UUIDs are compared without regard to case. A genuinely different UUID is still refused.
  • A zero empty-spool weight on the spool no longer hides the filament's or vendor's weight. The tag now gets the first weight above 0 (spool, then filament, then vendor). A 0 is written only when nothing is above 0, as before.
  • A wrong value in Spoolman now names the field. A weight, density or name that is negative or the wrong type used to report "does not fit this tag". It now says which Spoolman field to correct. "Does not fit this tag" remains for real lack of space.
  • A flaky NFC reader no longer floods the browser. Each NFC bus error triggered a refresh. The count is still in the NFC data; it just no longer pushes updates.

Not in this release: refusing writes and weight saves while a restart is pending (needs a station to test), and the screenshot-related items from the 1.1 cleanup list.

1.0.1-beta.2

Pre-release for testers. Internal cleanup; nothing changes for a user.

  • Removed code that only the tests used: the first-generation tag writer, the SPI bring-up for the NFC chip, the shared-I2C diagnostic, an unused tag-presence state machine, the runtime task table and the event queue. Their tests went with them. The code that reads and writes tags on a station is unchanged.
  • The tag-protocol check (check_production_nfc.py) now fails if any of the removed files comes back.
  • Removed two unused fields (boot_started_ms_, the Wi-Fi scan list in the diagnostics snapshot).
  • Documented that the reader driver has no host test.

1.0.1-beta.1

Pre-release for testers. The station no longer assumes a printer.

Printers are optional - Without a FilaBridge address the station does tags, weighing and Spoolman only. The touchscreen hides the Assign tab and button, and the Home screen keeps just Weigh, Manage tag and Settings. - First-run setup skips the Printer step when no FilaBridge address is set, and counts its steps to match ("Step 5 of 7" instead of "Step 5 of 8"). The FilaBridge step is marked optional. - Nothing changes for a station that already uses FilaBridge.

Known limits - The touchscreen has room for five toolheads. A printer that reports more (for example a Core One with INDX, up to eight) can be assigned from the browser only. - The browser interface still shows its printer sections when FilaBridge is not configured.

1.0.0

The first release. Everything below is in it.

Identify and weigh - Place a spool with an OpenPrintTag on the station and it reads the tag and finds the spool in Spoolman. Spoolman stays the record of what you own. If Spoolman was unreachable, the station looks the spool up again by itself when Spoolman is back. - Weigh measures the spool. Update Spoolman saves the remaining weight. Nothing is saved until you ask; saving automatically after each Weigh is a setting and is off by default. - Scale support for the NAU7802 amplifier with a YZC-133 load cell (5 kg by default, 2 kg selectable), with tare and calibration.

Tags - Write a blank NXP ICODE SLIX2 tag from a spool in Spoolman, update a tag after the spool changed, or move a tag to another spool. You can pick an existing spool or create one from a filament, on the touchscreen or in the browser. - The station checks every block after writing it and reads the whole tag again at the end. If a write or clear is interrupted, it offers to finish it the next time that tag is on the reader, or to skip it if the tag is lost. - Clear / Reuse erases a tag and removes its link in Spoolman. The spool stays in Spoolman. - Writing is one confirmation: pick the spool, check what will be written, Write tag. The station asks again only when the tag belongs to another spool or holds other data. The preview lists anything that does not fit on the tag (a long name or material, several colours). - Reading and writing show their progress, and the spool's colour is shown on the result. - With Spoolman 0.27 or later the station also uses Spoolman's own tag list: writing a tag links it to the spool there, clearing removes it, and a tag Spoolman links to a spool is recognised even if it holds no OpenPrintTag data. The two Spoolman extra fields are then optional. Each tag placed on the station is reported to Spoolman, so a Spoolman page paired with the station jumps to the spool.

Printer - Assign the spool on the station to a toolhead (T1–T5) through FilaBridge. The station asks before it replaces a loaded spool or changes a printer that is printing, and checks afterwards that FilaBridge accepted the change.

Station - A touchscreen with Home, Weigh, Assign, Tag and Settings views, and a web page with Dashboard, Inventory, Printer and Settings. Firmware updates, settings export and factory reset are in the browser only. - First-time Wi-Fi setup on the touchscreen, or through an open setup network OpenTag-Setup-XXXX and a browser. A setup network you start yourself closes after 10 minutes; on a station with an access token, the token is still needed over it. - An optional access token for the web page, and settings export and import that never include passwords or tokens. - Firmware updates from the browser keep your settings. After an update the station checks itself for 30 seconds and returns to the previous firmware if something is wrong. - A USB installer for new stations and recovery at https://76cb.github.io/OpenTag-Station/. It erases settings and calibration.

Good to know - The station works on your local network over plain HTTP. Do not expose it to the internet. - Firmware files are not signed. Only install files from https://github.com/76cb/OpenTag-Station/releases. - Supported hardware is the WT32-SC01 Plus with an ST25R3916B NFC reader. Only NXP ICODE SLIX2 tags can be written. - Saving weights needs Spoolman 0.26 or 0.27. Assigning toolheads needs FilaBridge 1.2.1 or 1.2.2. - The Community filament catalog is not part of this release.

The manual is at https://76cb.github.io/OpenTag-Station-Docs/.

Each release has these files: opentag-station-<version>-application.bin (update from the browser), opentag-station-factory.bin (USB installer image), manifest.json, build-metadata.json and SHA256SUMS.

The release candidates below were development builds made for testing before 1.0.0.

1.0.0-rc.23

The fixes for 1.0 found when the open issues were re-checked (#84). This candidate also contains rc.22 (touchscreen button colours), which was not published separately.

Safety - The setup network you start from the browser now closes by itself after 10 minutes, and Stop setup network closes it at once. The touchscreen Settings line shows "closes in N min". It can't be stopped while it is the only way to reach a station that has no working Wi-Fi. - Tagging many spools in a row from the browser no longer ends in "Idempotency ledger is full": browsing and searching the spool list no longer use up request slots, and slots of finished requests are reused.

Finding the spool - A tagged spool is looked up in Spoolman as soon as it is placed. Before, the lookup waited for a steady weight, so an uncalibrated scale (or one waiting for a tare) meant tags were never identified. - If Spoolman or Wi-Fi was down when the spool was placed, the station looks the spool up again by itself when Spoolman is back (up to three times, spaced further apart each time). You no longer need to lift and replace the spool. If Spoolman answers but the lookup fails, both interfaces say "The Spoolman lookup failed: …" and still let you link the tag by hand. - While Spoolman is unreachable or the lookup is running, the touchscreen Manage tag page and the browser dashboard say so ("Spoolman is not reachable…", "Looking up this spool in Spoolman…") instead of calling the tag "not linked".

Writing tags - The preview lists anything that will not be written to the tag: a name, vendor, material or article number that is too long, a material type the tag can't store (such as "PLA Matte" or "PLA+"), or several colours. Browser: "Not written to the tag:"; touchscreen: "Not written: …". Before, these were left out without a word. - A single tag-reader error no longer blocks every write and erase until a restart. A write fails only if the reader reports an error during that write: "The tag reader reported an error during this step. Try again." - Spool lists with large entries no longer fail a whole page: the station fetches fewer rows at a time, and both interfaces page correctly through shorter pages. - Tag actions are named after what they do. "Assign" is only used for printer toolheads: WRITE TAG / Write tag for a blank tag, USE FOR ANOTHER SPOOL for a linked tag, Write tag for a spool in the browser.

Scale and weighing - Tare is refused when the platform is not empty: "The platform is not empty (reads X g). Remove everything, then tare. If it is empty, tare again within 15 seconds." A second tare within 15 seconds is accepted, for the case where the zero itself has moved. - After a power glitch to the scale, the station reconnects to it by itself instead of needing a restart. - Weigh can't be started while a weight is still being saved to Spoolman; the button reads "Saving to Spoolman…" and a refused weigh says why. - The touchscreen Weigh page only shows a result for the spool that is on the station. After a swap it no longer offers to save the previous spool's weight. - Tare and calibration results, including failures, stay on the touchscreen until your next tap.

Touchscreen - Main actions are mint, erasing is red and other choices are grey on every screen (rc.22), including the setup guide, About and the toolhead question. - Setup: Next waits for the save and stays on the step with the reason if it failed. The printer list shows the printer that is saved. - The brightness set in Settings is kept after a restart, and display settings saved in the browser apply at once. About no longer has its own brightness slider. - About ten messages that described the software's internals are rewritten in plain words, and common errors on the tag failure page are explained.

1.0.0-rc.22

Touchscreen button colours - The main action on each touchscreen screen is now drawn in the product's mint colour: WRITE TAG, ASSIGN TAG, CONTINUE, WEIGH on TAG READY, CHOOSE EXISTING SPOOL, FINISH WRITING and the like. Erasing stays red. BACK, DONE and other secondary choices stay grey. Before, every tag button except the red ones was grey. - The setup guide, About this station and the toolhead confirmation no longer use LVGL's default blue. In setup, Next/Finish, Save and (until the scale is calibrated) CALIBRATE NOW are mint; Back, Home and Scan are grey. In the toolhead question, Assign is mint, and Replace or Assign anyway (during an active print) is red.

1.0.0-rc.21

Writing and erasing tags: fewer steps, one reminder - Touchscreen: tapping a spool in MY SPOOLS reads the tag and opens the review page straight away; "Use this spool?" is gone. After CREATE SPOOL the review page opens by itself. - Touchscreen: "Move this tag?" is now the review page itself, not an extra page before it. It also appears when the station's preview finds that the tag belongs to another spool, and a tag that holds another spool's data shows "This tag holds another spool's data. Writing replaces it." Before, the touchscreen showed the generic text in those cases. - Browser: Continue reads the tag at once and shows the preview; the separate Review step and its Preview tag click are gone. The steps are Select → Preview → Write → Done; an Edit step appears only while editing. Write tag asks no further question for an ordinary write; the extra question (and a red button) remains when the tag belongs to another spool, holds other data, or has an interrupted write. "Create this physical spool in Spoolman?" is gone. - "Keep the tag on the reader." appears once, and only while the tag is read, written, checked or erased. While only Spoolman is updated the browser now says "The tag is written. Saving the link in Spoolman…" (or "The tag is erased. Removing the link in Spoolman…"); before, it still asked to keep the tag on the reader. - After a finished clear in the browser, Done closes the dialog instead of reopening Manage tag.

Reading progress - The full read before a write or clear reports its progress (160 block reads, both passes). Touchscreen and browser show a progress bar; the background read shows a spinner with "Reading tag" / "Hold the spool still." - Two tags on the reader now show "Two tags on the reader. Remove one." on the touchscreen and "Tag not read" in the browser, instead of "Reading tag…" that never ends. - Progress messages from the station are plain: "Reading tag", "Checking tag", "Writing tag", "Erasing tag", "Verifying tag".

Spool colour - The touchscreen review and TAG READY pages show a ring in the spool's colour; the browser preview and result show a spool picture in that colour. - Home on both interfaces uses the Spoolman spool's colour when the tag itself has none. The spool API now includes primary_color.

Setup and About - The setup network OpenTag-Setup-XXXX is open; there is no password to read off the screen. When it comes back on a station that already has Wi-Fi saved, a station with an access token still requires the token over it. - The first setup page no longer shows "Configuration schema 3". It says "Tap Next to start", or, on a station that is set up, that you can review a step or go Home. - About this station is one scrolling column in a larger font, one value per line, in the sections Network, Scale and screen, System and Memory.

Scale - Every tare, including the zero step of a calibration, first re-runs the scale converter's own offset calibration, so the zero matches the converter's current temperature. If that tare then does not finish, weighing asks for a new tare instead of using a zero that no longer fits. - Both calibration screens advise calibrating after the station has been on for about 15 minutes. Troubleshooting explains warm-up drift and load-cell creep.

Releases - Every version merged to main is published automatically as a GitHub release (a pre-release for candidates) with the update file, and the USB installer is built from that same release.

1.0.0-rc.20

Spoolman 0.27 tag support - Writing a tag now also links it to the spool in Spoolman's own tag list (Spoolman 0.27 or later). Moving a tag removes it from the previous spool first, and clearing a tag removes it. These steps are part of saving the link in Spoolman, so the existing retry and recovery prompts cover them. - The station finds the spool through Spoolman's tag list first. A tag Spoolman links to a spool is recognised even if it holds no OpenPrintTag data, for example a blank tag you linked in Spoolman yourself: Home shows its spool, and Weigh and Assign work. - Tag IDs are matched in both byte orders, because some phones report them reversed. - On Spoolman 0.27 or later the two extra fields are optional. When they exist the station still fills them; when they don't, it uses Spoolman's tag list only and no longer warns about them. - Each tag placed on the station is reported to Spoolman, so a Spoolman page paired with the station (Spoolman: Settings > Tag Scanning) jumps to its spool. - A tag that Spoolman links to a filament, or to two spools, is refused before anything is written.

Fixes - Saving weights works with every Spoolman 0.26 and 0.27 release, not only 0.26.1. - After start-up or a Spoolman outage the station learns Spoolman's version again right away. Before, weight saving could stay off for up to five minutes. - A tag at the edge of the reader's range no longer flickers: one missed check is tolerated, and a read that fails part-way is retried after half a second instead of showing an error and waiting five seconds.

1.0.0-rc.19

  • The USB installer page now names the real update file, opentag-station-<version>-application.bin, instead of "firmware.bin".
  • Removed touchscreen code that could never run or show: button positions that were always overwritten, an auto-update button on the Weigh page that was created hidden and never shown (the one in Settings is unchanged), and a gauge update for a widget that only exists on Home. The source checks that required this dead text now check the live code instead.

1.0.0-rc.18

Refactoring. No behaviour change.

  • Touchscreen code is easier to read: the tag-flow model is formatted one statement per line, the per-page parts of the main refresh routine are separate functions, repeated colours have names, and declarations nothing used are gone.

1.0.0-rc.17

Refactoring. No behaviour change.

  • Web request helpers (idempotency-key check, SHA-256 decoding, lower-casing) have one definition instead of two or three copies.
  • The tag-writer snapshot limits have names instead of repeated numbers.
  • The update start-up checks shared by the update worker and the application have one definition.
  • The station no longer builds a full diagnostic snapshot for every web request, or re-evaluates start-up health fifty times a second, when the result is not used.

1.0.0-rc.16

Clean-up. No behaviour change.

  • Removed code that no build compiled (an unused ESP32 RFAL platform adapter) and functions and constants nothing called.
  • The sanitizer test environment now runs every native suite, not four of them.
  • CI no longer runs twice for each pull-request commit and caches PlatformIO packages. A branch without an open pull request is no longer built until one is opened.

1.0.0-rc.15

Browser fixes; no new features.

  • After a lost response, the same action (Weigh, Tare, the same search) is no longer blocked until the page is reloaded. The browser checks the earlier request and lets you repeat it once it has finished, or after 10 minutes if it cannot tell. The message now says what to do.
  • The Clear / Reuse button keeps one label instead of switching between two wordings.
  • Removed unused fallbacks for fields the station never sends.

1.0.0-rc.14

Touchscreen tag flow fixes; no new features.

  • The recovery prompt for an unfinished write or clear stays available after DONE, after leaving the Tag page and after a failed retry. In rc.10/rc.11 it disappeared until restart.
  • A tag reading error no longer replaces the recovery instructions.
  • Taking one tag off the reader and placing a different one starts the tag screen fresh; the previous tag's choices no longer carry over.
  • A progress screen started from the browser always offers BACK TO HOME, except while the tag is being written or linked. Edits made in the browser no longer move the touchscreen.
  • A mistake in the new-spool weights keeps the form and its values. Paging back after a failed page no longer opens later lists on the wrong row.
  • "Taking longer than usual" is timed per step, so linking after a long write is not reported as late.
  • The weigh button reads WEIGH until there is a measurement (it always read WEIGH AGAIN).
  • Printer override dialogs no longer show "TT1".
  • Weight updates no longer stay blocked until restart after a single NFC bus error.
  • Fixed an out-of-bounds read in the diagnostic trace of the update status request.

1.0.0-rc.13

Fixes to configuration, update start-up, scale and backends; no new features.

Updates (OTA) - An update record that could never move on (for example the new image was selected but the bootloader fell back to the old one) is now ended at start-up, so a new update can be uploaded. Before, upload, cancel and restart were all refused until a USB reflash. - A healthy new image is no longer rolled back when power was cut between selecting it and recording that selection. - Firmware older than the stored configuration no longer runs on defaults and then overwrites that configuration; it leaves it untouched, refuses to save, and lets the update roll back.

Configuration - The two Spoolman field keys must differ and use only a–z, 0–9 and _ (Spoolman's own rule). Backend access tokens may not contain control characters. Stored values that break these rules are repaired when the station starts. - Tagging more than 64 spools no longer fails at the last step of a verified write; the local list of confirmed links drops its oldest entry (Spoolman remains the record). - An unusable calibration left by very old firmware no longer blocks start-up.

Scale and weight - Calibration is refused when no reference weight is detected, instead of saving a meaningless factor; the message says so. - Changing scale hardware settings during a measurement ends that measurement with a message instead of blocking the scale until restart. - A Spoolman empty-spool weight of 0 no longer overrides a real value from the filament, vendor or tag.

Backends and Wi-Fi - One lost Spoolman version request no longer turns weight saving off for minutes; a failed Spoolman read check stays visible. - When a printer mapping was sent but could not be read back, the message says so and the printer list stays current. - Wi-Fi failure reasons now match the driver's codes: a handshake mismatch is reported as a password/security problem, "too many clients" as a router refusal.

1.0.0-rc.12

Tag writer and spool identity fixes; no new features.

  • Clearing a tag, retrying an unlink and retrying a link now check that the two Spool extra fields exist in Spoolman before looking up the owner. Without them Spoolman ignores the lookup filter, and the station could remove the identity of an unrelated spool or loop on "Multiple NFC UID owners".
  • A write or clear that is refused before it starts (for example the tag was lifted after confirming) no longer leaves a recovery record. In rc.10/rc.11 it blocked other tags, and after a refused clear even browsing spools.
  • A clear interrupted before the Spoolman settings were changed now shows the recovery prompt with the reason, so Skip recovery is reachable. It used to lock the writer in a failed state.
  • Recovery prompts no longer carry the previous preview's data.
  • A locally remembered tag-to-spool link is treated as a conflict when Spoolman now links that spool to a different tag, so the wrong spool cannot receive weight updates.
  • The same tag is recognised when Spoolman stores its UID in lower case or with separators; it is no longer rewritten with a new identity.
  • A spool list page that is too large to show fails with "This page is too large to show; narrow the search." instead of an endless "retry".

1.0.0-rc.11

  • Wi-Fi: when joining the network fails, the station now says why instead of always "Wi-Fi connection timed out": password rejected, network not found (2.4 GHz only), signal too weak, or refused by the router. The reason comes from the Wi-Fi driver and is shown on the touchscreen setup screen and in the browser, and logged with the network's signal strength from the last scan.

1.0.0-rc.10

Safety and usability fixes. No new subsystems.

Safety - WT32 printer assignment: the dialog's first button is now Cancel and only an explicit Assign/Replace confirms. In rc.9 the Back button performed the assignment. - OTA: the firmware now keeps a new image pending until OpenTag's 30 s health check (Arduino's early auto-confirm is disabled), so a failing update rolls back. A station left in reboot_pending by rc.9 now normalizes to confirmed instead of refusing every later update. - Spool identity: a vendor/material or product-barcode match is only a suggestion and must be chosen or linked before weights or assignments can target it. Lookups by extra.<key> are refused, with the field name to create, when the Spool extra fields do not exist (Spoolman silently ignores unknown filters). - Reboot, factory reset and OTA restart are refused while a tag or Spoolman operation is running. - The setup access point is WPA2-protected; its per-boot password is shown only on the touchscreen.

Tag recovery - A write or clear that fails while the station is running returns to its recovery prompt instead of a dead-end "Tag needs attention". - Writing a different tag no longer overwrites another tag's unfinished-write record. - Link/unlink failures show the reason. Skip recovery (touchscreen) / Skip linking / Skip cleanup (browser) stop a recovery that can't be finished. Factory reset clears unfinished tag operations.

Spoolman and weighing - Search falls back to the vendor name when no filament name matches, on the WT32 and in the browser. - A remaining weight above the spool's initial weight is refused before any change; missing initial weight and untested-version cases have specific messages. The Spoolman spool's empty weight now takes priority over the copy on the tag. - WT32 spool creation no longer defaults the empty-spool weight to 0 g: it uses the filament or vendor value, or asks for it. - Settings → Integrations warns about missing identity fields and untested Spoolman versions.

Touchscreen and browser - Weigh: WEIGH → WEIGH AGAIN, UPDATE SPOOLMAN highlighted when a weight can be saved, two-line status that says what will be saved or why it can't. - Setup: real NFC reader status (rc.9 always said "NFC disabled by wiring guard"), Next saves typed values, printer chosen from FilaBridge's list, CALIBRATE NOW returns to setup. - Tag: erase/skip actions are red, no "0 / 0 blocks" for Spoolman-only work, "1.75 mm" diameter, duplicate LINK/REASSIGN removed, paging back lands on the previous rows, no-change writes disabled, a way back from Spoolman requests that stall. - Settings → Wi-Fi & services on the touchscreen; larger About/Advanced buttons; toolheads show which spool is loaded. - Plain-language OTA wording and a link to the release files.

Release - Release candidates can be tagged v1.0.0-rc.N and are published as GitHub pre-releases with the OTA application image. The installer is rebuilt from release tags only. - The disabled Community catalog is no longer published on Pages or in releases (it also made the release file check fail).

1.0.0-rc.9

Community import/search is disabled for 1.0 after physical ESP32-S3 testing demonstrated a miniz inflater-state memory overwrite. The implementation is retained for redesign in 1.1.

  • My Spools and My Filaments remain available on WT32 and in the optional browser. Production rejects Community API/import actions and installs no catalog callbacks; no startup download, verify, inflate, or catalog access runs.
  • Failed browser NFC preview retains the reviewed physical spool. Retry Read uses the same spool and mode; Back to Review preserves values; Back to Select reloads the current source and clears stale rows. Busy state ends on completion or failure.
  • Update Existing Station uses application-only A/B OTA, preserving LittleFS configuration, NVS, scale calibration and service/printer settings. Factory Install / Recovery explicitly erases configuration and calibration. Disabled Community is not seeded into factory LittleFS.
  • Community is postponed, not fixed.

1.0.0-rc.2

  • Standalone WT32 selection from My Spools, My Filaments, or Community; physical spool creation, import/reuse, exact writer review, and reassignment without a prior clear.
  • Shared tag lifecycle: compatible blanks offer Assign; successful cleanup offers immediate reuse. Existing remote ownership and NFC safety fences remain mandatory.
  • Full-screen text, numeric, URL and password input with 44 px keys, explicit acceptance, cancel, and repeat backspace. Bounded inventory pages and streaming gzip Community search.
  • Explicit production version changes enforced in PR CI.
