I guess you have informed yourself about what the CAM system can provide?
In any case one should always do that before buying such a system...
Have you not processed any parts from your production line when the system was demonstrated to you?
I find it a lot more important what impressions you received about the software.
Everybody has different priorities and perceptions.
Did you take part in a training course??
3 weeks is not a very long time to say much about a system..
