I don't see anything wrong with combining wood with a 3m screw driven nut. The nut is a proven design running in EMS machines for years.

What's wrong with 16mm screws?
We will have to agree to disagree regards a wooden CNC machine.!!

Regards the 16mm screw then it's too flimsy over 3mtr and thou it it doesn't rotate it will still vibrate at higher feeds. Now you probably don't believe me because your thinking well it's under tension how can it.? But let me assure you that it will vibrate because even the 25mm screws I fit and put under heavy tension still vibrate at high feeds when the machine approaches the ends of travel and changes direction quickly. A 16mm screw will twang like a skipping rope.!!
