Found thuis on the net. Might be of interest for others to.

Thanks, Guido--VERY interesting video. A lot of what we do, in this community, involves linear translation And this was a soup-to-nuts discussion of an interesting, inexpensive, and seemingly powerful platform.

I found this video well worth its 20 minutes plus. Am very tempted to order some of their products, even if I don't immediately need them, to educate myself on this type of DIY linear translation.

Great find!

I wonder how accurate the system is. But it is used to make 3D printers so i gues it should be usable.

Here is an overview of things build with this system.

And here a simple stack system.

This platform seems optimized more for speed than resolution. Only one drive screw is currently offered; it provides 8mm of translation per turn. Compare this with a Cognisys stackshot, which provides 1.6mm of translation per turn.

So it would seem a poor contender for stacking movement. However, it might do nicely for rough positioning of a microscope focus block. There might be too much "play" for this, but it would be hard to determine without a specimen in hand.
