New to CNC's, recommendation for 2D wood cutting was created by Karks13

Hello, I am new to this forum as I am starting a woodworking craft that is taking off and I need help with a CNC recommendation. I cut (Thickness) 3/4" pine designs with a max width of 18”/length 25". I have done some research regarding CNC's but not sure if they are suitable for cutting ¾” pine designs. Can you please look at the 3 machine below and let me know if one is better cutting out my designs, or suggestions? I will mostly use this for CNC 2D Cutting. Any suggestions/recommendations would be great! I would like to keep my budget round 3k. See my attached pictures.
I also need to weigh out software and what would be best for my 2D cuts.

CNC's I am looking at:

I might not be the right person to answer this but the short answer would be neither.
Personally i would not consider any of those as "hobby", plastic wheels, direct driven belt or rack, etc, or in other words, the same thing is buying a 3D printer and mounting a spindle on.
They all probably work, very, very slow, with very soft wood, and wont last.
The best and cheapest (although still out of your range) would be to find an old industrial machine and retrofit it, not sure where you are, but here for 7 to 12K will get you an very nice machine that will make those parts by the hundreds per day.
I did say i am not the right person ...

Firstly, looking at your samples, none of the CNCs shown can make them, as they all have sharp internal corners that can not be made with a rotating tool.

I would avoid anything that uses an off-the-shelf router as a spindle too, they are _very_ noisy.

They all seem to use some form of GRBL (3D printer) controller, so are not compatible with LinuxCNC.

You might actually be better off with a laser, and cutting the parts in several layers then gluing in stacks. (I don't see a $3k laser cutting 3/4 material)

Welcome to the LinuxCNC forum, I spoke to you on the patriot wood working forum.

I see now you have a lot more items to make, I was thinking about making patterns and using a pattern bit but that thought went out the window.

Do you think you could build your own router table with 8020 material?

Only an idea. All those routers seem, I don't know, "thin" (english is not my first language), I'm building one with several different aluminum profiles, sheets, etc. But mine is for a router, for your designs I think a laser will do OK.
I also went not long ago to a local laser cnc cutter for a "very accurate" fret slots cutting template (for guitars) and was very displeased with the results, maybe the machine was not well tuned, I don't know, It went directly to the chimney pile.
However you must do trial and error with thick wood, the laser is literally burning the wood.
I attach a work in progress of my design just for fun.
