Has anyone ever heard this sound before?
It seems like it’s only on x pos moves. And worse (like above) at low speeds. I do hear what may be ‘grinding’ and some subtle squeaking at normal speeds. If I rest my fingers gently on the sliders as it moves it feels rough. Remember when I built this thing some of the teeny bearings dropped out of the linear bearings. Time to replace them?
I noticed when I was releveling the bed after soldering that sliding the x back and forth was not a smooth, free feeling motion.
