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

• 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.
