    Original Prusa MK3S squeaking loudly

    I have a very loud intermittent squeak in my Prusa MK3S. It's hard to tell if it's from x or y axis, but what did I assemble incorrectly? Do I have a bad bearing, is a belt too tight?

    I put a bit of the grease that came with the machine onto the rods, moved the axes to spread it, and the noise is gone. Should not have listened to the manual when it said not to lube the bearings. Otherwise am really enjoying this printer.

    it started again, and on further investigation it turned out that I had mounted the gear on the Y axis just a hair to close to the motor, so it was intermittently rubbing
