v1.1.0-OpenKE

Headline: the buzzer now makes real sound — pitched beeps and songs (zero-CPU, print-safe) — plus a soft touchscreen click. Also fixes the H.264 camera breaking when the printer's IP changes.

Added

• Buzzer beeps & songs (hardware PWM) — the onboard piezo plays real pitches via hardware PWM (zero CPU, safe to use mid-print).
  • M300 S<freq> P<ms> — the standard slicer beep, now with real pitch and duration.
  • PLAY_TUNE SONG=<name> — play songs from an editable songs.conf (ships with mario / zelda / starwars + success / error jingles; add your own RTTTL tunes; the file is preserved across reinstalls). PLAY_TUNE RTTTL=<string> plays a one-off.
  • BEEP — a quick confirmation chirp.
• Soft touchscreen click — optional, phone-style tap feedback (Settings → Touch Beep, default off); far quieter and lower than the stock beep.
• Link to a 3D-printable screen mount (Thingiverse #6617266).

Changed

• M300 is now a real hardware-PWM tone (its S/P parameters finally matter) instead of a fixed-pitch buzz.
• Change history now lives here on the Releases page (in-repo release notes removed).

Fixed

• H.264 camera survives IP changes — the Nebula (go2rtc) webcam auto-refreshes its Moonraker URL to the current IP on every boot, so a DHCP/IP change no longer requires re-running the installer.
• Uninstall now removes songs.conf.
• Docs: clarified the wrong-sensor-labels fix (re-run the installer); new Beeps & Songs wiki page; updated camera/upgrade pages.

---

Upgrading from v1.0.0 or earlier: update the screen via Settings → Update Guppy, then re-run the installer once to pick up the new M300/PLAY_TUNE macros + songs.conf (the on-screen updater swaps the binary but not the Klipper config). See the Upgrading and Beeps & Songs wiki pages.

v1.0.0-OpenKE

First stable 1.0 release of OpenKE. The touch UI, the vendored print-quality mods, and a
self-contained one-shot installer now come together as a single package — and, from this release on,
every version is documented here. (Content-identical to the short-lived v0.6.0-OpenKE tag, which this
release supersedes.)

Added

• On-screen: stoppable filament Load (stops cleanly instead of running forever); an Invert Y
  homing-jog toggle (bed-slinger feel); auto-cooldown of the hotend after a manual
  extrude/retract/load/unload; a Spoolman "Use this filament?" confirmation before a manual load; and
  a regrouped Tune tab + rebalanced Settings panel.
• Guided on-screen input shaper — calibrates X/Y one axis at a time with an
  accelerometer-placement confirmation before each axis (correct for the bed-slinger: toolhead for X, bed
  for Y), locks Calibrate/Save while a run is in progress, shows progress and recommendation
  toasts, presents the frequency-response graph + a readable console side-by-side, and has a watchdog
  so a hung run can't spin forever.
• Hardware H.264 camera stream (go2rtc) — a low-bandwidth WebRTC/RTSP feed for the Creality Nebula,
  alongside the stock MJPEG.
• Vendored Klipper mods under k1/k1_mods/klipper_mods/ (ship in the release tarball): KAMP
  (adaptive mesh + purge, pre-edited for the KE), Axis Twist Compensation (Klipper v0.12.0 module +
  idempotent probe.py patcher), and TMC Autotune (evgarthub K1 fork). Each carries its upstream
  LICENSE/NOTICE; see docs/VENDORING.md. No more cloning other repos by hand.
• Installer "optional features" prompt with install-all / skip-all / choose-each — set up any
  combination of: KAMP, Axis Twist, TMC Autotune, Skew Correction, the Creality Nebula camera
  (persistent image tuning + H.264 stream, as one option), and the Pause/Resume layer-shift fix
  (y_park 222→220). Config installs via the GuppyScreen/*.cfg include mechanism; only the Axis-Twist
  probe.py patch and the layer-shift gcode_macro.cfg edit touch existing files, and both are backed
  up first and guarded (skipped if not applicable).
• Self-contained Nebula camera persist macros (nebula_camera.cfg) — re-applies image settings on
  every boot so they survive reboots, with or without the Helper Script's CAM_* macros.
• Vendored Creality macros (GPL-3.0, from the Creality Helper Script) as their own installer option:
  M600 filament change, Save Z-Offset (native z-offset persistence — no longer delegated to the
  Helper Script), useful macros (backup/restore, PID, bed-level, warmup), and Exclude Object
  (+ enable_object_processing in moonraker.conf). Each .cfg installs only if its sections don't
  already exist (section-conflict guard), so it never causes a duplicate-section crash.
• Real, split wiki — User vs Developer sections, plain "reddit-style" guides, including new
  Perfect prints — start here and Calibration, explained (recalibrate-vs-reset, hardware-change
  matrix) pages. Publishing mechanism documented in Publishing this wiki.
• This CHANGELOG.md.

Changed

• Rebrand GuppyKE → OpenKE across the README and wiki (the touch UI is now framed as one part of a
  perfect-prints toolkit). Git repo name unchanged, so existing installs/updaters keep working.
• guppy_cmd.cfg now ships [guppy_config_helper], so the on-screen TMC Autotune Save works without
  a manual edit.
• Mod/install wiki pages rewritten: the installer does the setup; manual steps kept as an advanced
  section on each page.

Fixed

• Filament-runout Cancel dialog — now shows "Cancelling print…", disables its buttons, and stays up
  with feedback until the print actually stops (the runout sensor could otherwise re-fire and re-pop it).
• Input shaper — fixed a crash after each axis (a result toast read the wrong JSON key); the console
  shaper list now lists shapers in the same order as the graph legend (Klipper's INPUT_SHAPERS
  order) instead of alphabetically; ASCII-only toast text so it renders cleanly in the compact font; and
  a much longer calibration watchdog (the KE's numpy analysis is genuinely slow, ~3 min/axis).

Safety

• A fresh timestamped printer.cfg backup on every installer run; probe.py backed up before the
  Axis-Twist patch. Re-running the installer does not rewrite saved calibration values.
• Fully reversible uninstall — installer.sh uninstall restores the Creality display/app stack from
  backup and renames Monitor/display-server back automatically (guarded), so both install choices
  revert cleanly on the next reboot.
• Duplicate-section guards: the installer detects an existing [axis_twist_compensation],
  [skew_correction], KAMP, M600, Save-Z-Offset, or Exclude-Object setup and leaves it alone instead of
  adding a conflicting copy. The check looks only at actively-loaded config files (printer.cfg + its
  [include] globs, nested) and only at uncommented section headers — so it correctly ignores the
  KE's commented-out stock sections (e.g. #[filament_switch_sensor ...]) and the *.bak/printer-*.cfg
  backups in the config dir. Verified against a live KE under its BusyBox.

v0.5.5-GuppyKE

Changed

• WiFi power-save toggle renamed "Low Latency" and expanded into a full bundle — it now disables WiFi
  power-save, turns off background roam-scans, and stops Bluetooth (the BCM4343 shares one antenna for
  WiFi/BT, and the coexistence caused latency spikes).

Added

• TMC Autotune user guide — explains the greyed-out Save button, documents all four tuning goals,
  and notes the Sensorless Threshold is hidden on the KE.

Fixed

• WiFi "Low Latency" hint left-aligned and shrunk (montserrat 14→12) so it clears the Back button.
• Broken Skew documentation link; completed the README documentation index.

v0.5.0-GuppyKE

Added

• Skew Correction panel in the Tune tab, plus a printable skew-calibration frame.
• 0.001 mm Z-offset baby-step option.
• First end-user wiki pages + README refresh.

Fixed

• TMC Metrics crash on TMC2208 drivers (no CoolStep/StallGuard) — guarded; the CoolStep +/- adjusters
  are now hidden on drivers that don't have them.

Changed

• Dropped the bundled skew-calibration g-code — slice your own square instead.

v0.4.0-GuppyKE

Added

• Guided Axis Twist Compensation calibration wizard in the Tune tab.
• WiFi power-save toggle for lower latency — re-applied on every reconnect / network switch, and a
  boot-race fix so it survives a reboot.
• Documentation: KAMP + Axis Twist Compensation first-layer guide (wiki + README link).

Fixed

• "Now printing" overlay jitter — steadied and made into a single tap target.

v0.3.0-GuppyKE

Added

• Power Settings (renamed) with a Power-Loss Recovery section.

Fixed

• OTA in-app updater now points at the coreflake1 fork, ignores nightly, and filters release assets
  correctly.
• Bed-mesh table + 3D rendering made robust for KAMP adaptive and dense meshes.

Changed

• CI actions bumped to Node 24 majors; dropped the orphaned lv_drivers build-time patch.

v0.2.0-GuppyKE

First GuppyKE-branded release — the big on-screen feature wave.

Added

• Live Z-offset baby-stepping panel (0.005 / 0.01 mm steps, guarded when not homed).
• Firmware Retraction live-tuning panel.
• Console redesigned as a drill-down command browser.
• Macros redesigned — favorites, collapsible rows, button navigation.
• Notifications split into toasts, modals, and a print-done screen; on-screen toasts for Klipper events.
• Fans — friendly names, read-only fans (heater_fan / output-pin fans), correct editable/read-only split.
• Exclude Object — tap-to-exclude bed map during a print.
• Spoolman filament confirmation at print start.
• Print-status overlay reworked — bigger, preview-led, with a "Paused" chip; Homing/Extrude allowed while
  paused; the mesh is viewable (not mutable) during a print.
• Extruder heats all filament actions to the selected temp, with clearer feedback.
• Mainsail-matched ETA (averages file / filament / slicer estimates).

Changed

• EMA-smoothed resistive ns2009 touch input for smoother scrolling.
• Thread-safe State::get_data, tighter LVGL cadence, evdev tracking-id press fix.
• CI: lv_drivers now fetched from the coreflake1 fork (no build-time patch).

v0.1.2-ke-fixes

Added

• Print-status: filename label, dynamic ETA, auto-dismiss when done.
• Extruder: non-blocking heat, auto-extrude on reaching target temp, busy spinner.
• KUtils::notify_toast transient feedback and a gcode_script response-callback overload (groundwork
  for later guided flows).

Changed

• CI builds only the Ender-3 V3 KE release asset; added a self-hosted cross-toolchain Docker image.
• Busy spinners normalized to 80×80.
• User-focused README rewrite + in-repo wiki.
• Reverted the v0.1.1 "LED on home / Fine Tune in Tune tab" change.

v0.1.1-ke-gui-fixes

Added

• 480×272 small-screen layout + a global font pass for the KE.
• Bed-mesh panel redesign — table by default, 3D fullscreen.
• Panels gated behind print state (LED ↔ Fine Tune swap).

Fixed

• Display sleep on the Ingenic X2000 DSI — disable fbdev_blank on sleep (the panel was otherwise
  unrecoverable) and invalidate the screen on wake (fixes the white screen after sleep).
• display_rotate=2 default for the KE's upside-down screen mount.
• Reduced LV_FONT_DEFAULT to montserrat_12 on small screens.

Changed

• Installer: uninstall mode, printer.cfg backup before modify, silent-include fix, and guards for
  files the KE doesn't ship.

v0.1.0 - KE Advanced 3D Bed Mesh

Initial release of the KE fork, based on ballaswag/guppyscreen.

Added

• Advanced 3D bed-mesh visualization with interactive controls.
• Chamber temp on the print screen, default extruder temps, and a WiFi "forget network" button.
• Installer / release scripts adapted for the coreflake1 fork; documented the full fork lineage.
