Well, one good point for the bearings is that you use bearing grease, which is much better than oil. But linear bearings are louder than brass. The question was mainly: Does it really improve the prints quality or anything else?
@SusisStrolch Too tight in general
@Dr_Vegetable I meant, I stopped after mounting one, wondering if I should do the other 2 as well. The brasses are broken in so they feel really adjusted. Of course, they won’t ever stop making the oil turn to black, it’s totally normal. But the bearings sound louder to me. I’m just wondering you know, I guess I could just try. But I want to reprint the sledges first so I’ll try in a while, first re printing on the other printer
@shelxle Had exactly the same happening on the first printer. Since then I have kitchen paper folded around the shafts bases, no more leakages
