"Saved us 6 hours on an SVM fault last Tuesday. The flowchart walked our apprentice through a fault I would have taken a day to diagnose. Worth every penny."

"The Siemens 840D module can't come soon enough. What's there for Fanuc is exceptional. Called David once at 11pm about an Alpha PSM fault — he picked up."
