I finally bit the bullet and attended the Tormach Sprutcam and CNC workshop. 4 days. It was money and time well spent for me. I am a novice machinist and have had my PCNC 1100 for a little over a year now. I probably picked up enough in offline discussion alone to more than pay for the class and the travel. Getting to use a PCNC with a tool changer (sweet!!) spoiled me though. Sometimes not knowing what you are missing is a good thing.
