Im new, am a 3D designer. Need a New cnc machine and need advice and guidance

[FlyHighRC]

So what would I need? I wouldnt mind designing my own design and sticking up some renders on here for you guys to approve..If I build it I could then upload the files for anyone else to have a crack if the design works :) I suppose if its a homebuild then I could Increase its work area right?

The things I know Ill need

1)Steppers motors
2)Stepper wire
3)Link stuff
4)Controller
5)Stepper Drivers(Any all in one driver boards?)
6)Linear mechanisms? Any recommendations for for round bar or square rails?
7)Some sort of router..again any suggestions?
8)sacrifical bed, i see this this is most often MDF

Have I missed anything?

Where can I buy extrusion? And any dimensions online? Would really help with putting this all into Solidworks :)

Thanks again guys

regarding screws and rail most of us use chia in the link he does the rail and ball screws,there are others but he was the only one ive come across that will machine the screws to length as well as end machineing to your specs to cater for pulleys should you use them.

profile rail would be nice but even used you might be pushing it on your budget.
