Overkill CNC Router Upgrade Part 5 - Chatter free Z-Axis Design

My DIY CNC router build continues with the Z-axis assembly. I explain the design considerations and the pros and cons of moving rails vs. moving blocks designs for Z-axes and the impact on overall rigidity. Furthermore, I show the complete assembly and a few tips and tricks for ball screw assembly. This is part 5 of a series, documenting the build of my latest design of a DIY woodworking router.
