xTool RA3 World's First Smart MagSwap Rotary for xTool P3

Quick verdict

Based on published specs and editorial comparison, the RA3 MagSwap rotary is an accessory rather than a standalone engraver, designed to extend xTool P3, F2 Ultra, F1 Ultra, and F2 machines onto curved items like rings, tumblers, and ornaments. Its 360-degree LiDAR mapping alignment targets makers who need repeatable, accurate engraving on cylindrical and irregular surfaces. Consider it the workflow add-on that unlocks round-object work for compatible hosts, per its listing.
