Community Firmware V4.2-R5 — CC2 Control 1.1.31

CC2 Control gains print history, auto-refill controls and timelapse selection in the print popup. Camera streaming starts on request and releases the viewer when it closes or hands over to another CC2 page.

Changes

• Print history, timelapse generation and deletion of selected history records. Deleting history records does not delete G-code files.
• Timelapse selection in the print popup, including calibrated print starts.
• Auto-refill controls and machine error/status reporting.
• Persistent UDS queries, Quick Action light-state feedback and heater-action guards.
• Camera ownership across CC2 pages and windows, integrated from PR #71.
• Automatic printer serial discovery using the saved LAN credentials.
• LF shell scripts and explicit executable permissions in the prepared firmware component.

Downloads

• CC2-Control-1.1.31-R5-Multiplatform-Update.zip: CC2 application updater for Windows, Linux and macOS. Includes backup/restore scripts and the matching source snapshot.
• CC2_V4_2_STOCK_20261004_135126_9cead4b7.zip.sig: complete stock-signed firmware with CC2 Control integrated.
• CC2-Builder-V4.2-R5-CC2-Control-1.1.31.zip: matching builder and prepared component. Private signing keys, AES key, original firmware and SquashFS executables remain external inputs.
• CC2-Control-1.1.31-R5-Source.zip: CC2 application sources.
• SHA256SUMS_V4_2_R5_RELEASE.txt: checksums for the release assets.

Installation

Use the application updater to update CC2 alone, or the signed firmware to update the integrated image. Extract the updater ZIP before running the launcher. The startup delay remains 60 seconds after the vendor printer process appears; the installer waits up to 240 seconds for application readiness.

Windows SSH host-key recovery remains explicit: use -ResetHostKey only for an expected key change, and verify the new fingerprint before accepting it. Existing LAN credentials are preserved; an initial installation still needs valid LAN credentials.

Validation and provenance

Repository commit: d630ac4a37ec9a7d1644deef87e796e903b5b29a (merged PR #69, incorporating PRs #67 and #71).

The integrated application was tested on a printer by the maintainer. Component host tests, ARM compilation and builder integration checks passed. The uploaded firmware passed independent SHA256, stock RSA signature, OTA manifest/SWU linkage, RootFS content, launcher LF/755 and init-link checks. The exact newly packaged firmware image has not yet undergone a fresh on-printer installation test.

Acknowledgements

A huge thank you to DamiBFryta, our dedicated beta tester, for consistently helping us with ideas, testing and debugging. Your feedback and commitment have been invaluable in improving CC2 Control and the community firmware.

Thank you to @beanbo for printer sub-states, refusal reporting, Canvas auto-refill and print history in PR #67, and camera ownership across CC2 pages in PR #71. Thank you to @Surfoo for the UI rewrite and continuing UI contributions on which this release builds.

Vendor components retain their original provenance and notices.

CC2 Control 1.1.31fix — Missing Features & Improvements

A small standalone update for existing Community Firmware installations. Saved LAN credentials, material presets and UI preferences are preserved. Internal service version remains 1.1.31; the full firmware release remains V4.2-R5.

Fixes and improvements

• Restore 3D bed-mesh visibility and keep its framing stable during rotation.
• Bound automatic Canvas discovery across MQTT reconnects, expose diagnostics and retain explicit Sync.
• Identify G-code tools by colour and material during Canvas print setup.
• Fix intermittent browser uploads and report existing-file refusals without misleading network errors.
• Show the newest 128 G-code files, indicate hidden older files, and place the upload card above the list (PR78/PR80).
• Windows launcher includes -ResetHostKey %* for explicit SSH host-key recovery and argument forwarding. Verify the new fingerprint before accepting it.

The thumbnail-priority experiment was discarded and is not included.

Installation and validation

Extract the updater ZIP and run Install-Windows.cmd on Windows, or sh install-cc2-control.sh <printer-ip> on Linux/macOS, while the printer is Idle. This updates CC2 Control without reflashing firmware.

Gino confirmed the PR80 test installer works on the real printer. The final package contains the exact same ARM executable and compiled UI. All release PR82 CI checks passed: host tests and ARM build, sanitizers, UI build and firmware-builder tests. Installer and browser upload/delete/duplicate checks also passed. Checksums and detailed validation notes are attached.

Thank you

First, special thanks to Surfoo for the splendid complete interface redesign and continued localization, themes and release-consistency work.

Thanks to beanbo for File Manager improvements, printer sub-states, refusal reporting, Canvas auto-refill, history, camera ownership and Russian translation. Thanks to Skcycos for Simplified Chinese and Surfoo for French and JSON localization.

A huge thank you to our beta tester DamiBFryta, who keeps helping with ideas, debugging and real-printer feedback. Thanks to everyone testing and reporting issues.

Community Firmware V4.2 — CC2 Control 1.1.30

Community Firmware V4.2 — CC2 Control 1.1.30

Community Firmware V4.2 integrates the stable CC2 Control 1.1.30 release.

Important

After installation, wait for the printer services to finish initializing before opening CC2 Control. An additional reboot or power cycle is no longer required: CC2 Control realigns its local MQTT, Canvas and snapshot services automatically after the LAN access code is registered.

Highlights

• unified Bed Levelling workflow with Side A / Side B saved meshes;
• adaptive G-code probing and automatic full-bed calibration when the selected side has no saved mesh;
• four-screw corrections in microns with guarded reference optimization;
• Canvas material and spool selection integrated into print preparation;
• global Emergency Stop and operational Quick Actions;
• persistent English/Italian language and dark/light themes;
• G-code/3MF file manager, multi-selection, bulk delete/copy, thumbnails and OrcaSlicer upload/print support;
• filenames containing spaces and UTF-8 characters;
• live job data, object statistics, total layers, elapsed and remaining time;
• protected console, homing and printer-state safety guards;
• Panda compatibility service on port 7125.

Final 1.1.30 fixes

• rejects implausible G-code temperature metadata instead of displaying values such as 6211 °C;
• restores fast preview behavior by displaying the thumbnail before the full metadata scan;
• caches metadata by storage, path, size and modification time;
• removes remaining example/demo file information from live views;
• automatically realigns CC2 Control after first-run LAN-code registration, without restarting the printer.

CC2 Control 1.1.31 — Orca Canvas Sync and LAN Code Revalidation

CC2 Control 1.1.31 — Orca Canvas Sync and LAN Code Revalidation

CC2 Control 1.1.31 is a standalone update for existing Centauri Carbon 2 Community Firmware installations.

No full firmware reflash is required.

What’s new

OrcaSlicer Canvas filament synchronization

Added optional compatibility for OrcaSlicer when using the Moonraker printer agent.

CC2 Control now exposes the read-only endpoints expected by OrcaSlicer:

• GET /server/info
• GET /server/database/item?namespace=lane_data

Canvas tray data is mapped into Orca-compatible filament lanes, including:

• slot / tray ID
• material type
• filament colour
• maximum nozzle temperature

The existing Octo/Klipper workflow, Device tab, upload flow and Canvas print-selection popup remain unchanged.

Thanks to @efiten for the original proposal, investigation and printer-side validation.

LAN access-code revalidation

The printer LAN access code can now be replaced directly from:

Settings → Connection

Enter the new code and select:

Change / Revalidate

CC2 Control writes the replacement configuration atomically and restarts only its own service.

The printer itself is not rebooted or power-cycled, and the normal printer services remain untouched.

The documented SSH recovery procedures are still available as fallback options if configuration access is lost.

Installation

If you already run an earlier Community Firmware release, use:

CC2-Control-1.1.31-Multiplatform-Update.zip

The updater replaces only CC2 Control and preserves persistent configuration, material presets and interface preferences.

Supported updater platforms:

• Windows
• Linux
• macOS

Included files

• CC2-Control-1.1.31-Multiplatform-Update.zip
• CC2-Control-1.1.31-Multiplatform-Update.zip.sha256.txt
• CC2-Control-1.1.31-Source-and-Multiplatform-Builder-R1.zip

Verification

SHA256 for the standalone updater:

13a7badebcfb63c734c444cc45c638d2eb62d0291daadf45a1b86a8277a756ec

Always verify downloaded files before installation.

Compatibility

• Community Firmware V4.2
• existing Community Firmware installations using CC2 Control
• OrcaSlicer standard Octo/Klipper workflow
• optional OrcaSlicer Moonraker-agent filament synchronization
• ELEGOO Canvas 4-slot material system
• Panda / Moonraker-like compatibility bridge remains unchanged

Notes

This release updates CC2 Control only.

Community Firmware V4.2 itself remains unchanged.

The next full firmware release can include CC2 Control 1.1.31 directly.

Community Firmware V4.1 — CC2 Control 1.1.25

Community Firmware V4.1 is focused on the full integration and stabilization of CC2 Control 1.1.25 for the ELEGOO Centauri Carbon 2.

Important

After the firmware installation has completed and the printer has booted normally, reboot the printer once more.

This post-install reboot is required so CC2 Control, Canvas state, MQTT registration and the background compatibility services initialize against a settled printer runtime.

V4.1 was validated with complete firmware installation cycles on physical Centauri Carbon 2 hardware. The R8 integration fix was additionally validated from a fully clean /opt/usr state.

R8 clean-install fix

R8 fixes the first-run error Connection failed: Cannot save configuration that could occur on a completely clean installation. CC2 Control now waits for the persistent UDISK filesystem to be mounted on /opt/usr before creating its configuration directory and seeding material presets. Existing LAN codes, preferences and presets remain preserved during upgrades.

CC2 Control remains version 1.1.25; R8 is a firmware-integration revision.

Highlights

• CC2 Control 1.1.25 integrated into the firmware
• CC2 Control available in browser and in the OrcaSlicer Device tab
• Live camera, temperatures, fans, current job and service health
• G-code file manager with USB/internal storage and thumbnails
• Canvas four-slot management and material presets
• Canvas spool-selection popup before multicolour prints
• Bed Mesh 2D/3D and isolated four-screw load-cell tramming
• Object Exclusion support
• Protected expert console with homing and motion guards
• Panda / Moonraker-like compatibility on TCP 7125
• API v1 capability/discovery endpoint
• Original elegoo_printer kept unchanged

CC2 Control 1.1.26 — Multiplatform Hotfix for Firmware V4.1

CC2 Control 1.1.26 — Multiplatform Hotfix for Firmware V4.1

CC2 Control 1.1.26 is a targeted dashboard and workflow hotfix for printers already running Community Firmware V4.1.

This update affects CC2 Control only.

No firmware reflash is required.

The package is multiplatform and can be installed from:

• Windows 10 / 11
• Linux
• macOS

using standard SSH/SCP tools.

---

What’s fixed in 1.1.26

Dashboard and graphics

• multiple dashboard layout issues corrected
• improved visual consistency across controls and status panels
• clearer presentation of live values
• cleaner Bed Mesh presentation
• improved overall workflow and readability

Temperature controls

• nozzle and bed temperature changes are now applied atomically
• Control page live readings are better aligned with printer telemetry
• temperature workflows are more consistent between UI state and printer state

G-code file handling

• filenames containing spaces are now handled correctly
• UTF-8 G-code filenames are supported
• multi-selection added to the file manager
• bulk deletion is performed sequentially
• copy operations between internal storage and USB are streamed instead of being fully buffered in memory
• demo/example file handling no longer interferes when no real file is selected

Print workflow

• Side A / Side B selection is available where applicable
• print-source handling is clearer
• file-selection behaviour has been improved

Bed Mesh

• saved default and default1 meshes are recognized correctly
• Side A, Side B, active and adaptive mesh states are handled separately
• saved, adaptive and full-bed mesh workflows are presented more clearly
• Bed Mesh graphics and UI have been cleaned up

Persistent settings

The updater preserves existing:

• LAN code / CC2 Control configuration
• UI preferences
• material presets

Safer update process

Before replacing the current installation, the updater creates a backup.

After installation it verifies CC2 Control through:

http://127.0.0.1:8081/api/health

The service must report:

"version":"1.1.26"

If the health check fails, the installer automatically restores the previous CC2 Control installation and restarts the service.

Installation

The computer and printer must be connected to the same local network.

You will need:

• the printer IP address
• the printer root password

Default root password:

MTY4ODE2

If you previously changed the root password, use your own password instead.

The password may be requested more than once during installation because the package first copies the update to the printer and then starts the remote installation.

Windows 10 / 11

Extract the ZIP, open PowerShell in the extracted folder and run:

Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass -Force
.\Install-CC2-Control-1.1.26.ps1

You can also specify the printer IP directly:

.\Install-CC2-Control-1.1.26.ps1 -PrinterIp 192.168.1.103

Replace 192.168.1.103 with the actual printer IP.

On the first SSH connection, type:

yes

when asked to trust the host key.

Then enter the root password:

MTY4ODE2

The password is not displayed while typing. This is normal.

If Windows reports that ssh or scp cannot be found, enable the Windows OpenSSH Client optional feature.

Linux / macOS

Extract the ZIP, open a terminal in the extracted folder and run:

chmod +x install-cc2-control-1.1.26.sh
./install-cc2-control-1.1.26.sh

Or specify the printer IP directly:

./install-cc2-control-1.1.26.sh 192.168.1.103

Accept the SSH host key with:

yes

and enter the root password when requested.

---

Verify the update

Open:

http://PRINTER-IP:8081

CC2 Control should report version:

1.1.26

You can also verify through SSH:

wget -qO- http://127.0.0.1:8081/api/health

---

Compatibility

• Printer: ELEGOO Centauri Carbon 2
• Required firmware: Community Firmware V4.1
• Previous integrated CC2 Control: 1.1.25
• New CC2 Control: 1.1.26
• Full firmware reflash: not required

Important

This archive is not a printer firmware image.

Do not copy it to the printer USB drive expecting the ELEGOO firmware updater to install it.
Extract it on your Windows, Linux or macOS computer and run the included installer.

Centauri Carbon 2 Community Firmware v3.9

Centauri Carbon 2 Community Firmware v3.9

This release integrates CC2 Control 1.1.17, a lightweight local control
platform that runs directly on the ELEGOO Centauri Carbon 2 and is available at
http://PRINTER-IP:8081.

Supported printer: ELEGOO Centauri Carbon 2 only
Required base: official firmware 02.01.00.00
This is an independent community project and is not affiliated with or
supported by ELEGOO.

Highlights

• Klipper/Fluidd-inspired local dashboard with live printer telemetry.
• Live camera, temperature history, job status, motion, heater, fan, light,
  speed and flow controls.
• Protected Klipper console and guided PID, input-shaper and bed-mesh actions.
• 11×11 Bed Mesh heatmap and interactive 3D surface with real X/Y/Z references
  and adjustable Z exaggeration.
• Native ELEGOO Canvas detection through MQTT method 2005.
• Four live Canvas slots with colour, material, temperature range, load,
  unload and material editing controls.
• Persistent built-in and user-defined material preheat presets.
• Internal and USB G-code library with protected print submission.
• Canvas spool-mapping dialog for single- and multicolour G-code files.
• Reliable USB printing: files from the USB root or nested folders are safely
  imported into internal storage before the validated local start request.
• First-run browser configurator; no manual configuration-file editing is
  required for a clean installation.
• Automatic startup through procd with delayed printer/MQTT/Canvas discovery.
• Very small runtime footprint: approximately 560 KiB RSS in validation.

CC2 Control 1.1.17 maintenance update

• Fixes the protected console remaining busy after long resonance and bed-mesh
  calibrations filled the previous 64 KiB output buffer.
• Expands retained console output to 256 KiB.
• Detects completion directly from the printer stream, including JSON markers
  divided between separate reads.
• Releases a saturated calibration stream safely after ten seconds without new
  reports; the printer operation itself is never cancelled.
• Includes a Windows one-click SSH hotfix installer for users already running
  Firmware V3.9, without requiring a complete firmware reinstall.

Existing v3.8 features retained

• Root SSH access.
• Extended GUI Z-offset range.
• Dual Trust v2: official ELEGOO and community-signed update support.
• Local HTTP/upload service in LAN-only and WAN/cloud modes.
• Upload while printing when supported by the client.
• MQTT LAN/WAN coexistence and OrcaSlicer WAN telemetry.
• Local webcam access in WAN/cloud mode while Matrix remains operational.

ELEGOO-Web v4.4.0

ELEGOO-Web v4.4.0 is the stable bilingual release of the portable Windows controller for the ELEGOO Centauri Carbon 2 local web interface.

New in v4.4.0

• Complete Italian and English localization of the desktop interface.
• Immediate language switching without restarting the application.
• Localized buttons, labels, status messages, printer discovery results, network errors, QR messages and configuration warnings.
• The selected language is saved in config.json and is also used by the printer Web UI.
• Automatic serial-number, hostname and model detection introduced in v4.3.0 is retained.
• Manual serial-number entry remains available as a fallback.

Requirements

• Windows 10/11 x64 with .NET Framework 4.8.
• PC and printer reachable on the same local network.
• TCP port 8888 available on the PC.

Extract the complete ZIP and run ElegooWeb.exe. No Python, WSL, PowerShell, administrator privileges or compilation are required for normal use.

Do not distribute config.json: it contains the printer Access Code in plain text.
