I tried multi-color 3D printing with Elegoo's AMS-like CANVAS module - here's how it went

A hands-on review of the Elegoo Centauri Carbon 2 paired with the CANVAS multi-color module. The CANVAS system uses four PTFE tubes to feed up to four filaments into a single-nozzle printer, producing quality multi-color prints. Key advantages include a price point over $120 cheaper than Bambu's P1S Combo. Downsides include significant filament waste from purging during color swaps, a four-filament limit (vs. Bambu AMS's 16), and uncovered spool holders. Control options include a touchscreen, the Elegoo Slicer app, and unofficial Home Assistant integration via LAN-only mode. Overall considered a solid budget-friendly option for multi-color 3D printing newcomers and enthusiasts.
