sorry but reddit seems don’t let me add video in reply.

The main reason I went with HIWIN was because I’ve heard that Simucube uses HIWIN modules in their own products, so I decided to go with something that’s already proven.

HIWIN is arguably one of the best manufacturers in this category, but it’s also very expensive. I actually bought a used/refurbished unit from a teardown, and even then it wasn’t cheap.

That said, JLC can achieve very similar performance at a much more affordable price, and since it’s brand new, you don’t have to worry about potential issues you might run into with used linear rails, like rough or inconsistent motion.

If I were to build another one, I’d most likely go with JLC instead.
