Not exactly! on linear lead screws

I bought these for my 3D printer. The details looked great. Very easy. However, I had severe Z streaks. After checking the rest of the machine, I mounted a travel indicator on the Z axis and mapped the lead screws. The step turned out to be correct, but each round the move was wrong. Basically, the advance is too small for the first half of the revolution and too large for the second half. Looks like the lead screw is bent on the lathe that made these lead screws. I replaced the Hictop leadscrews. They work great.

Pros

diameter 8mm

Cons

wrinkled packaging
