I'm about to CNC a "CNC ready" bench mill. I'm seriously considering getting the Flashcut 3 axis Servo kit. I've come up with a list of pro's and cons and would greatly appreciate comments.
Pros for the Flashcut CNC Servo
1) USB interface rather than a parallel port. The USB interface may be much more reliable and available.
2) Separate function generator so Windows multitasking may not be a problem.
3) Servo motors that may have advantages over steppers.
4) Complete kit available so there should be no compatability issues
Cons
1) Expensive (but not out of budget)
2) Forced to use Flashcut software (this might not be a disadvantage if it is reliable and supported)
