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 squeaking again and on further investigation, I had the gear on the Y axis a hair too close to the motor, so it would intermittently rub. Moved it about 1mm and now no problems.

started again, so I took everything apart, got some white lithium grease and packed all the bearings using www.thingiverse.com/thing:1974253I did have to use a tap & die set to rethread the tube and the greaser, but it worked well. Now 3 days later with no more squeak. Lesson learned, even though the manual says no need to lube them yet, grease the bearings right away. |
