Reddit scan:1) I bought some Linear BB on amazon with good reviews, but there were only 6 reviews. I'm pretty sure they're junk and I should send them back, but want to double check how well other people's linear bearings work. If you have "great" ball bearings, if you put them on a rod, at what angle do they slide down under their own weight? I feel like that if you hold the rod at like 45 degrees, they should roll down. The ones I bought, some of them don't even roll down when the rod is perpendicular to the ground (90 degrees).2) All my experience is in Cura with machines in a Makerspace. Is there a software package out there that lets me manually rotate motors so that I can test how well they're working? http://ift.tt/2rHWuQs by Towson Makerspace
