The top slide as uploaded uses LM6UU bearings it appears. I was able to export the STL from the SCAD file but had to also make changes to the code to fix some issues with Repetier complaining about the mesh. Basically the cutout for the rails had a problem. I've sent the code change to PacManFan in hopes he can correct those two issues... but until fixed just know that you'll need to likely do the same to get good results from a print.
Like you had mentioned, it is really determined by the thread of the rod and maximum speed of the motors. I've had my 5/16 20tpi threaded rod up to 200 mm/s pretty reliably, your results may vary.
Looks great. How fast linerar motion can this handle? How long does it take to go a full travel length at maximum safe speed? Looks like 8 or so inches travel distance in the picture there. Can it do a A to Z travel in 1/2 a second? 1/4? Or more like every 2?
I assume this can be adjusted based on the threaded rod.
Thanks, looks great.

- Small section of rubber tubing to go over the threaded rod.
- 608 skate bearing
- 5 mm x 25mm long bolts + nuts
- 1/4 threaded rod + matching nuts
- 8mm or 5/16 rails,
- 4x lm8uu linear bearings
- anything else I forgot to mention...
Assembly should be fairly straightforward, The only tricky part I encountered was aligning the threaded rod through the nut on the underside of the slider. Make sure the indentation of the nut on the bottom section of the slider can fit the nut properly. I used a dremel-like tool to clean mine up so everything aligned properly.
