Here is a link to a current build log:

The machine is about the same size you are planning for. Maybe he is ready to help you out, and maybe you can take a trip to him and have a look... Even if he is not in Cambridge, in your case I think it is worth to take a trip even if it might need a night in a hotel or B&B. He can definitely give you an idea about a realistic budget.

Thank you A_Camera for taking the time to send me an in depth reply, it really is appreciated. I'm quickly believing I am out of my depth. Drowning in my innocence. I was quite confident to begin with, but that as now evaporated.

Having spent many hours watching videos, reading builds, searching the Internet. I am now totally lost, confused and despondent.

Back to the drawing board.

Thank you once again

Clarification, all my 3D Printers have the option of printing from GCODE but I use them connected directly to a laptop or Desktop PC and can make changes on the fly. I have never used the SD card approach. The software I use if Simplify3d or Repetier Host.

There is no need to spend more hours watching videos. Here on this forum 99% of the builds are exemplary plus the guys earlier have pointed you to all the details.

Just to resume:
nema23 3nm motors on all axis driven by AM822 at 70VDc
1610 ball screws on all axis, 1605 on the Z, pulleys HDT5 15mm wide 20t from motor to ball screw
2.2kw spindle is the typical compromise between power money and ability to cope with tasks
20 size square rails Hiwin or chinese copy, don't use open builds or v rollers or skate rollers or other crap.
buy all hardware from BST Automation Aliexpress or other reputable seller.
Either use the recommended aluminum profile or make a structure from 80x80x3 or 100x100x3 box section.

Just read the builds in forum, all is there detailed and with pictures. i don't know what is with all to imagine that they are engineers and design every single machine from scratch. Just copy a well known and successful build and spend your time using the machine, instead of designing it. if you are into welding use my first build as inspiration and there are free plans in Sketchup. If you are into aluminum even better, many good builds.

You will need proper motion controller, not 3d printing solutions. Ethernet is what people use nowadays, not USB. CSMIO and Mach3, offline DDCSV1, UCCNC controller and software and so on.

Also you will need a seriously big enclosure, Power supply ets.

Once you start the build thread people will help you there so all will progress fast. But at the end of the day you will need to read some build logs,. Without that it will be too long to explain all. And dont read logs from the Zone as you will get too much useless information in your head.
