Support blocks are missing

As with most other reviews, I've read that the bearings are pretty rough. The pillows I was sent were also missing. Decently straight and therefore not a very good rating.

Pros
  • 4 pcs. Shaft support SK8, 4 pcs. Bearings SCS8UU
Cons
  • Only available in white

Who needs screws?! Right?

Amazing they made the holes and got them to me quickly. But I don't see anywhere that they mark the size of the thread. not a big problem for sliders, but this lead screw block will be hard to come by. I think it's worth what you spend. and it's only temporary for the project.

Pros
  • 2pcs 200mm linear shaft guide
Cons
  • Long delivery

Much better quality than I expected

Linear bearings run smoothly and are driven by a stepper motor. The screw has four threads, so it turns pretty fast. I use a NEMA 17 stepper motor to drive it and at 200 steps per revolution it moves the "table" that I attached by 1/25 millimeters with each step. The only thing that could be used in this set is a couple of cross bars that all the pieces could be attached to. You can also use eight more M4 x0.7 screws.

Pros
  • Lead screw 8mm (200mm)
Cons
  • Not sure
