Yesterday I tried modifying a compact lifting frame I built a while back, and the moment I attempted to add smoother vertical travel, the entire mechanism revealed limitations I didn’t expect. The guide rails moved unevenly, and the manual lever kept sticking at random points, making the adjustment process oddly unpredictable. Since I’m rebuilding the core section anyway, I figured it might be time to incorporate a motion component that offers controlled travel without the constant need for recalibration, but I’m unsure what type of device provides that kind of consistency.
