Z-axis for 3Drag/K8200 My solution: zero wobbling, zero backslash, 4 options

A new follower nut support reduces wobbling and backslash.
Here the design for a better z-axis kinematic using stainless steel threaded rods or trapezoidal threaded rods, single or double motor.
Theoretical analysis, comparison of performance, parametric scad files, step by step guide, for a complete solution tailored according to the needs.
