The bit was a 1/2" 90 degree vbit.
The machine did work the first time but there were a few kinks to work out to make it more precise. I did ask a few questions on a CNC forum and got some very good help. The router travel is more or less figured by the software. A person could change the travel if he wanted to spend the time, but I had just as soon have the CNC make a few extra trips. Quicker for me.
Here is a video of the CNC cutting out a few knobs to use on handmade jigs -

Also is a couple of pictures of the 5 point and 8 point knobs after they were removed from the blank. Just takes a couple of licks with sandpaper, some paint and add some tee-nuts and they are as good as the ones you buy. There is just so much stuff a fellow can do with one of these machines. They are excellent for making patterns.
