I am going to build my own CNC router. I will only be cutting wood. I figured I would pass this by some others who know better than I do just to see if there are any glaring issues or unreputable sites in my list. Anything major I might be missing?

Linear motion, X & Y axis:
2x set of 2 linear rails and 1 ball screw w/ mounts. (2000mm)

1x ball screw w/ mounts
https://www.amazon.com/Joomen-Machin...st_bbp_dp&th=1

This gives me a total of 4 linear rails and 3 ball screws. One rail will be unused, but they don't sell them in singles. I would use a screw and rail for both sides of the X axis, then a screw and rail for the Y.



Z axis:
1x Ball screw w/ mounts (200mm)

2x Linear rail (200mm)

Table:
40 series extruded aluminum to build the table from the ground up.

Should I go with the 80mm ones though?

40 series 45 degree angle 160mm supports

Joining plates also.

Router:
2.2 KW router, inverter, clamp

I have seen spindles without inverters. Do I really need one? I've also seen people slap a DeWalt in and go. Trying to cut costs if possible. I'll only be cutting wood.
I also saw one setup where it was hooked up to a transformer, but another setup where it looked like they just hooked into the wall.
This part of my project I understand the least about.



Stepper motor + driver kit: (566oz, Nema 24, encoder, 5A motor, 55mA driver)
4x https://www.omc-stepperonline.com/cl...nd-driver.html

Power supplies, 36V (36 recommended in motor specs), 6A (taking a guess here!):
4x https://www.amazon.com/Utini-Power-S...c&sr=1-29&th=1

I haven't gotten around to the smaller brackets and such that most things would be attached to, but that will be easy.

Thank you!
