Planning on a build: how to select a good driver+motor combo?

**Noplace** · 17-01-2015

thanks for the info! offtopic question if you dont mind, I've been looking at ball screws, found some at automation4less.com which looks like a decent site but the prices for the screws and its parts is kinda steep, I did find on ebay also from chinese sellers, question is does it matter which one I pick in quality or are the chinese good enough ?

The sellers listed here seem to be the most popular, I think the Chinese stuff is fine, many people here use it.

yes, it matters i believe. Like Eddy says- Linearmotion bearing, solar jean . I buy from BST automation /aliexpress/ - Fred. He has all, from drivers to ball screws, same price as Chai and overall very good experience. Good at fixing mistakes also. The machining is 0.01mm spot on.
