Hello, here is my new machine

[hanermo2]

As the others said..
buy nothing more for now.

Try it, learn, the sw and jargon and endless stuff related take lots of hours.
It is much better to learn with a cheap kit machine.

Because you see Your errors faster, and ..
broken (tool) bits cost 2-5£ vs 500€ - 2500 € (machine bits), each.

This is like most common sw ...
none of it is logical, rational, well thought out.
Lots of it works "wrong",
sometimes it has errors, like engaging the reverse gear on the hw, because You put on the radio.

But it IS repeatable, simple, and productive, and very efficient.

After You learn to make "widgets" You yourself will know perfectly well;
- what you need to change,
- why, and
- can then look at how much £ for Your needs/situation

Your goals re:easy materials and easy work, are the easiest there are.

So You are 99% ahead of 99% of people who often want to machine 3d steel pieces of 1m volumetric work area/cube, often in 5 axis.

I was one of those, in 2002.
100k€ current-value-kit later, commercial industrial cnc training and work later, 17.000+ work hours later, I have a scratch built VMC nearing completion again, version 5, and a 3 axis 1 micron resolution CNC lathe refit, version 3, running sans pretties (tin aka guards, boxes for IO at lathe, energy track cables,..).
15 years, mostly full-time...

Your starter machine is an excellent option.
You learn with it, cheap, and once You can make something, anything, with it, YOU will be evaluate better what YOU want or need to do.
There are no wrong or right answers.

I know and have met customers / hobbyists from all extremes.
ANYONE can make stuff of EXTREME value on very poor machinery.
Handmade firearms or watches are 2 extremes.

Clockmakers/watchmakers and model-engine builders are 2 common examples.

But 99% cannot make money at it, unless You are at some extreme of skill/sport/brand/capacity most do not have.

A small cheap CNC cannot be profitable, ever, because the cash/investment grows by pwr2/pwr3 vs machine system total cost.

So a e.g. 1000£ CNC machine system CAN technically, of course, make parts for widgets YOU invent/control/sell to Your captive market for a profit, yes.
But YOU can get the same parts made for 50-80% less cost, from your friendly local CNC machine shop, using 70k€ machines.
Who wont know, care, or want to know, what You do, make, sell, or what the parts are for.

My point:
Your competition is NOT what your machines cost/produce/how good they are.
Your competition IS, really, can I get these built cheaper myself or elsewhere.

Mostly, almost no-one can make a rational argument for making parts ..
for testing, prototypes, learning, absolutely.
Or for controlling customer info/data like plaques/serial numbers/engraving/trophys/etc.
