The acceleration was at 20, now at 80. I use Quantum and the path smoothing feature. Jerk is set to 200"/s^3 with a 2% adaptive. I've long since forgotten why I chose those values

I reran the circuit (this time with a V-Bit). It's no faster than the video, but jogging is improved. Again, I suspect there just isn't enough room to go full speed.
Now for a math question (before I go to Google to help): I really like the quality of the ball nose cut on this copper. Can some one tell me the trig equation to find the diameter of the bit at a specified depth of .003"?
Thanks,
Jay
