* Fix: Disable redundant toolchange retraction for Elegoo Centauri Carbon Sets `retract_length_toolchange` to 0 in the Elegoo Centauri Carbon (ECC) machine profile. This resolves an issue where a massive filament blob would form on the prime tower immediately after resuming a manual filament change (M600). The blob was caused by a conflict between OrcaSlicer's default toolchange logic and Elegoo's hardcoded firmware behavior: - Elegoo's firmware (specifically the `cmd_PAUSE` and `cmd_RESUME` sequences) completely takes over pressure management during an M600. It performs its own initial 2mm retraction, a 120mm purge, and a silicone brush wipe, returning the print head to the prime tower perfectly primed. - Previously, Slicer was unaware of the firmware's priming and would issue a redundant 2mm un-retract (`G1 E2`) upon resume. Forcing 2mm of filament out of an already-full nozzle created the blob. By disabling the toolchange retraction (`0`), Slicer correctly hands off filament pressure management during an M600 entirely to the Elegoo firmware, preventing double-retractions and eliminating the blob. * fix errors after merging main --------- Co-authored-by: SoftFever <softfeverever@gmail.com>
