Not 100% sure this is the right forum for this but here it goes. I am looking to build a relatively decent cnc mill/router for materials like 7075 aluminum and hardwoods. I chose this as my final project in my robotics course(and probably bit off more than I can chew)so it must be completed by early-mid January. Can anybody possibly give some parts lists that I can look at to see if I'm missing anything? This is what I have so far(I will simplify it just so it isn't too tedious to look through)

3x ball screw(Sfu 1204)(end bearings and supports, nuts, and couplers as well)

3x Nema23 stepper motors (2.8A)(not sure if these would be powerful enough for milling something like 7075 Al)

6x limit switches

1x Arduino Uno(one of the requirements was that it uses an arduino or a raspberry pi)

1x Gshield stepper driver

+ various structural pieces that will make up the body of the machine

Anything else that I'm missing?
