Trying to make a homemade positioning system for CNC and if it goes well might try my hand at 3D printing at a later time. However, need some insight from some more experienced people on some choices. My goal is to do wood and thin aluminum with this.
I have 3 questions but any extra insight is welcome.

1/4 - 20 Right Hand Acme Lead Screws & Nuts for Power Transmission - Roton Products, Inc.
K so I've been looking for linear screws and think this site online has the best deal I can find. Decided on 1/4" - 20 screw because it was cheaper then the 3/16" - 20 and has similar efficiency but can handle considerably larger loads.
Can someone give me some insight on how to pick my nut/flange setup? Plastic good or not worth it? I don't mind investing in brass nut/steel-flange but at $55 a piece They come out to nearly the same prices as my NEMA 23 425 oz-in motor a piece so that has me hesitant to buy at the moment because that doesn't seem right.

Any place someone would recommend to get a linear rail system and what type would you all recommend? I'm shooting for a size of 2'x2'x1' and 3-axis, but think the ultimate size is determined by the price of the rail system.

Not really a linear question but any recommendations for a router to use? i'm familiar with the electronics end, but the mechanical end is pretty new to me.
