Let me start by saying that I would not want to hazard a guess as to what motor/size/power would work in any particular application – there are too many variables.
IF you are talking about the router from my plans, I’m comfortable to say ‘no’. Personally, I believe NEMA 17 are good for low torque applications like 3D printers or laser cutters.
For applications (like milling) that need power/torque, I would (and I did) err on the side of too much power. You will sacrifice speed and acceleration the larger the motor, but you will at least have torque!
