I get it—those micro‑tremors are like stray pixels on a high‑resolution canvas. First, isolate the source: a loose bearing, a worn spindle, or even a slightly mis‑aligned motor can introduce that jitter. Run a quick vibration analysis with a simple sensor; the data will point you straight to the culprit. Once you’ve identified it, replace or tighten the component, and then apply a small damping layer—silicone or a calibrated spring—right at the point of contact. After that, re‑measure. If the figure still drifts, tighten your tolerance grid: redefine the acceptable range, then iterate. It’s like editing a photo: you can’t let a single pixel ruin the whole image. Keep the process incremental, and don’t be afraid to discard a tool or a method that doesn’t meet the exact standard—sacrifice, for the sake of symmetry.
