Hallo
I am going to build my very first cnc router table.
I was looking for ball screws and linear rails. My table dimensions will be around 1000 x 1200mm.
I found linearmotionbearing2008 (chai) on ebay which offers really cheap prices - but i dont know if they are good
I´ve already read the tread here in the zone about his screws, and all reviewd that these screw arent the best but very good.
I got price from him for one 1250mm ballscrew (endmachined) with nut (16mm) and 5mm Pitch. Total with nuthousing and bearing blocks is 140 USD
the ballscrew itself is 54usd
I asked him about the accracy from the ball srew - he answerd that they are Precision rolled, class 7 accuracy; JIS (0.050/300mm) (0.002"/12") that means that i have only 0,2mm accuracy on 1200mm total lenth
So know i am not sure if that would be a good deal.
Is March3 able to correct that devation from the screw?
Hope you can help me
