Printer: Centauri Carbon (CC1) running Cosmos firmware (Kalico fork: OpenCentauri/kalico)
Goal: Manually run the equivalent of FULL_CALIBRATION with checkpoints, capturing state before and after each phase to identify exactly where (and why) calibration fails.
Trigger a USB-tethered camera for Cosmos timelapses instead of using the printer's built-in camera. Rendering is offloaded to a Linux desktop so the printer's R528 SoC doesn't have to do video encoding.
The printer fires a small HTTP call per layer to a Flask shim running on a Linux desktop. The shim calls gphoto2 to capture from the camera and saves the JPEG locally. At print end, ffmpeg renders the frames into an MP4.
