Bob Warfield - CNC Cookbook/G-Wizard Founder has passed away. 
A notice on the CNC Cookbook website indicates that they are suspending new trial offers at this time, and that they will attempt to keep existing products available “for as long as reasonably possible”.
A sad day for those who have known and interacted with Bob, and an uncertain future for those using the very helpful G-Wizard Calculator and other CNC Cookbook products.
That is such a huge loss. That site has taught me a ton over the years. Wish I could have met him just to shake his hand and say thanks.
That happened to the Arduinoclub guy in Germany a year ago with 50 years. His was the first board I used. Stuff like that really hurts even though you don’t know the people personally. 
Communities benefit so much from these kinds of contributors, and are lessened when they are lost.
