    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.

    Reading the manual for my new i3 Prusa MK3.  It says we should grease the linear bearings every couple months. Could take it apart but instead I just greased the rods and moved it around.  Silenced a similar rattle I was getting a few days ago.  Now the noise on my printer is coming from the fan.

    That’s easy enough to try.

    Lol.  I have used so many printers for so many years. I never knew until this last week.  I feel kinda like “well duh”.

    It’s strange that it’s only in one direction.
