Y-axis noises

Hello,

my y-axis makes terrible noises, but why? All bearings have been renewed.

Any ideas?

Best regards,

Dont know ,my X axis bearing makes simular noise but not as loud as that ,more rubbery. I oil it a lot but doesnt seem to make any diference. I have already changed it once ,but it still does it. Dont know why either.

My Y axis makes a similar noise. I think belt tension has something to do with it as the noise has definitely got worse since I tensioned the belt.

Does the noise go away if you loosen the clamps that secure the bearings to the bed support? It could be that the clamps are trying to rotate the bearings out of alignment.

Hmm possible, but I cannot imagine. I recently changed back to LM12UU just before recording. Therefore the bearings were printed so the noise would have been changed if I am not wrong.

Maybe the belt tension is too high that would fit to jsv555 and Darathy who managed somehow to do this on the x-axis.

I had this and couldn't get rid of it for ages, swapped bearings etc. In the end I tracked it down to a misalignment of the belt. I hadn't tightened the screw on the back of the motor enough and it had worked it's way loose. This meant the motor was pulling forward throwing the belt very slightly out of true. I tightened it up and the noise went away. I now have a redesigned motor mount that has a front brace eliminating the need for the difficult to get at rear screw. [www.thingiverse.com]
