🔩 Reliabot Hardened Linear Chrome Plating Review

I need to replace 2 Y axis rods on my Prusa i3 mk2s. Out of the box, these wands are smoother than the ones Prusa uses. Upon closer inspection, I noticed that when these bars are placed on a perfectly flat surface, they flex slightly, although not by much. The default stems that Prusa uses were 99.9% straight. In general these new rods work well.

Just a little thing. At the ends of the core bed, the cutter has increased the diameter a bit, since it just fits freely in the accessory, it's easy to grind off a tiny bit of that edge. The body is hardened and chrome plated - it's a strong material but there's no problem on the grinding wheel. This is good stock and will make it easier to assemble a lot of small machines since there are so many accessories available.

I tested several rods with a dial indicator to check straightness. I use a digital HF dial gauge on a magnetic stand. The key to getting consistent results is a pusher that moves across the rod so that a slight xy position error doesn't affect the dial indicator reading. I use a piece of glass as it provides a perfectly flat rod surface. Good standard bars usually have an out-of-roundness < 0.05 mm. Unfortunately one of my boxes was damaged in transit but one of the poles was not damaged. It
