Re: CNC macro rail

You can buy complete linear rail assemblies including the stepper motor for probably little more than the cost of the components. Here's an inexpensive one that uses a trapezoidal screw and brass nut. This supplier has a number of types and lengths including ball screw driven units for not much more. Have a look in Store Categories on the left of the page:
