This machine is awesome. It looks like a very strong start for a full aluminum build. All the ball screws are there. I also don’t see the metal bearing rod. Are those behind the wooden plates?

I believe, if you look closely, he is using linear rails.

Yes, I’m using linear rails, but I don’t know what’s best. I was wondering back and forth if I should go for the metal bearing rod or these linear rails. Anybody knows what’s best to use? I guess it depends on the quality anyway, and these are quite cheap ones bought on Aliexpress. They even seem to be missing some balls. But they work… (In fact the bottom (y-axis) uses rails for drawers and that works pretty well also. Very cheap.)
