| Mechmate uses rack and pinion. www.mechmate.com The Best way could be different things to different people. Ballscrews get very expensive at longer lengths and larger diameters. Rack and pinion can be accurate, and is much less expensive than ballscrews. Also easier to keep clean than ballscrews.
