robotic arm vs creating a cnc mill

[ineedwater]

New to all of this. but thought of asking you all if it's a good idea to use a robot arm by putting a router on it or just create a CNC mill?
Any limitations in using this? tnx in advance

What are your priorities for this? If you care more about precision and being stable, then a CNC mill is better. But my opinion is that robotic arm is more versatile. So... up to you. Just my two cents.
