Dimension consistency test round

thingiverse

I created this test to investigate why my prints no longer reach exact heights. I started by printing a standard test cube, then designed a series of nested pyramids to pinpoint where the issue begins. Upon examining each pyramid's first layer, I noticed that it is slightly lower than the subsequent layers. Further inspection revealed that at this critical point, the leadscrew on my z-axis becomes increasingly difficult to turn, indicating exactly where the inconsistency arises.
