[QUOTE="Timber_MG, post: 36640, member: 18"] Thank you for taking the time explaining these concepts so well ludo. The ACME/ trapezoidal thread (almost the same thing, one is cut at 29 the other at 30 degree angles and imperial/metric) has a higher drive efficiency and requires less power to do the moving than a standard thread (meaning you can get faster motion for the same drive power. It doesn't have so high an efficiency that it back drives though (like a ball screw or a rack and pinion where you can move the motor shaft by exerting a force like from a weight). Trapezoidal threaded rod is a fair bit more expensive though (in the states hardware stores carry it for a faction of the price here) [/QUOTE]
