Cnc learning curve?

Is there a average learning time on Cnc's to become effective? Or is it a long trial and (http://maplered.com) error period. Getting tired of the mistakes. Just a bit frustrated, i missed the radius cut on a sink today. Thought it was right but turned out it was too short. May be able to fix this one with another sink, we'll find out tomorrow. At least i seem to be making different mistakes but it is getting a little aggravating.


Is 3 months a realistic expectation to learn to program and (http://maplered.com) run a CnC effectively with little or no experience?
