DIY CNC milling machine parts checklist

hello there
After 4years working on CNC milling machine I decided to make one of my own for some extra cash
past few months I've spent in researching and finding out what I really want
it came down to 1500x1500x500mm (1200x1200x250mm working area)
I'll be working hardwood, plastics, and maybe some aluminium from time to time

about design
for X axis, I'll be using linear guide rail 20mm with 2010 ballsrews on each side
for Y axis, 2x linear guide rail 20mm with 2010 ballsrew
and for Z axis, linear guide rail 20mm with 1605 ballsrew
Frame will be welded steel and gantry 90x180mm extruded aluminium profile
Z axis will be mounted on 150x500x20mm aluminium plate

I think that covers up what I want, here's the list I came up with

4x 4Nm closed loop steppers KIT with drivers and power suplly from stepperonline
Motors link

3kW air cooled spindle from rattm-motor with VFD (it's cheaper then 2,2kw)
SPINDLE
VFD

inductive switches and emergeny switch (still have to find which one)

I was plannig to use MESA 7i96 STEP DIR I/O daughtercard
correct if I got something wrong
for that card I need separate 5V power supply ?
card power

I've seen lots of projects where ppl use buch of other stuff in their system (noise filters, fuses etc)
Do I really need those, or can I just connect everything according to schematics ?

I'm sure I missed something, so before I go on shopping spree, I'd be grateful if you can point me and correct before I buy something wrong or something that I dont need
thanks in advance

here's a rough idea of what I'd like to make
Cheers, Goran

I think that you probably should expect to need a line filter for the VFD, but they do not add much to the cost.

DIN rail breakers are neater than fuses, and are a one-time cost. They can be had in very small sizes: uk.rs-online.com/web/c/fuses-sockets-cir...&sort-order=asc&pn=1

Pricing seems random.

thanks for advice
gotta look up for that too then
anything else I'm missing ?

Equipment wire, ferrules for the wires. Connectors (I like Neutrik SpeakON for steppers, rated 20A)

yea of course
what about mesa cards, is MESA 7i96 STEP DIR I/O daughtercard alone enough ?

Get the 7i76E if possible.
