I finally had time, and (Nitto) awesome double-sided tape to run the G-code for the BLTuner pcb I had written about earlier.

Excellent results! And I was being a total chicken$hit with the feed rate, I could have run it easily at 4 inches per minute.

There were actually two toolpaths: the first was the actual pad isolation and the second was cutting the small board out. I did the first with the 3mm V-bit sold by Zen Toolworks and the profile cut-out with a 1/8 ballnose.
