Hello

Are the mgn guide rail, bars in 3030, 2020, ball screws on aliexpress worth it?
The prices are interesting on this site but quality levels?

I have had good experience from AliExpress supplier such as RDC: https://www.aliexpress.com/store/group/ ... .512538442
They need to be cleaned and relubed (ensuring the right number of balls are inside of them)

My current HevORT runs RDC rails on Z but original Hiwins on X and Y

This is a really good idea to use original hiwin on XY and the generic mgn on z.
The precision is more important on xy.

I just visited this thread to ask whether it was better to get Z or XY rails in the "value" models....Z is the obvious answer, because those things are long, but I saw that video in the Facebook group of someone's longer rails bent out of usefulness. Wondering whether the shorter underbed Z rails are worth getting Chinese because they're so tiny.

the linear rails I bought arrived. Apparently everything is ok. The smaller ones came clean and well lubricated, while the 550 had a bit of dirt. I bought in this store:

when I test I give feedback.

I don't find 385 or 485 mgn12H for 315 or 415 x axis.
Cutting this linear guide is not easy?
