Community Firmware V4.0
Firmware V4.0 integrates CC2 Control 1.1.22, a lightweight on-printer web dashboard available at http://PRINTER-IP:8081.
V4.0 adds four-screw load-cell bed tramming, protected object exclusion for labelled multi-part prints, a temporary expert G-code terminal unlock, and a minimal read-only Moonraker-compatible bridge for BTT Panda Breath on TCP port 7125. It also corrects the Bed Mesh X orientation and keeps screw-measurement output isolated from the stored 11×11 mesh.
The release retains live telemetry and camera, temperature history, protected controls, custom material presets, ELEGOO Canvas support, 2D/3D Bed Mesh visualisation, and printing from internal memory or USB folders.
Hardware validation and testing contribution: Barry Green.
For the project's technical background, architecture discoveries and implementation record, see CC2 Research & Technical Findings.
