ripper is the most versatile hobby CNC ever developed. The 3-Axis CNC was not designed for a specific application – ripper fusions the needs required for fast shape-cutting in wood/PVC and the strength and stiffness required for milling in aluminum and copper. It brings the precision down to fractions of the human hair – and can be build using simple tools! And all that at a cost which puts commercial available CNCs in this price-segment back to the kindergarten.
