I like my supported rail it's lovely and smooth but it's no Hiwin.
Thats what i am talking. Its cheap, its not Hiwin but hey, its supported bearing. Thats what i call the real "budget solution". It will work much better than any V and skate bearings. And i have such small machine /V with skate bearing/ from the time when there were no cheap Chinese bearings or machines. And i am telling you this is one of the things in life that have frustrated me most. I dont wish that to anybody. It will go in the museum of Bad engineering
