There’s little to no torsional play in the bed of my printer since fitting the Vesconite Hilube bushings and I cannot see any deficiencies or print problems in my parts. They’re as good or better than what I was getting before. Square parts are square and surface finish is very good. My ears are also very happy! I was printing in power mode the other day and it was only the actual motors themselves (and fans) that were audible. If I ever run into Z axis issues, I now know what I’m going to buy to replace those bearings.
