A practical, honest guide to hobby-tier CNC routers for engineers who already own a 3D printer: chip-load math, CAM workflows in Fusion 360 and Carbide Create, workholding strategies that actually hold, cutting aluminum on a gantry machine without lying about it, dust and noise reality, the current Shapeoko/Onefinity/PrintNC/LowRider/3018 landscape, a starter tooling set, and the learning curve mapped against FDM.
