Re: CNC Router vs 3D Printer

Frankly I suggest the 3D printer if that's what you want.
Just be prepared it will be obsolete before you blink.

However I have the following concerns about your spreadsheet:

1. What does the first choice use for the stepper controller / driver?
The Gecko is an excellent product I would recommend it.
It is already in the second choice you present.

2. Do the electronics kits include the power supplies?
If not budget for that as well.

Both of these kits (the first I have actually assembled before for someone) are ACME screw kits.
They have power loss in the screws and no provision to gear them (direct shaft coupled).
Their rapids are listed unloaded. In short you won't move anywhere near that fast while doing any operation.
These are more targeted for engraving on aluminum and working softer materials like wood.
You could work on aluminum with this but very slowly.
Neither system includes the coolant you might want for working aluminum.
You could retrofit this into a 3D printer but the Z axis depth might be a limit to consider.

Neither system includes any kind of dust collection or enclosure.
