But the brass one is now about 75% done, so I can probably test it yet tonight. I did find what I hope was the last carving bug about half an hour back, I'm watching the backplot, trying to figure out why I seem to have a small nick in one edge of the slot, and noticed that the descent point was no longer being wrapped up by the subsequent 4 moves to carve the slot. It turns out that apparently there is a negative limit to the math, and when the angle, which started at 360 & counts down, wasn't being reset at the top of the next loop start, and somewhere around -7200 degrees the math was failing. Fixed that, restarted it at the interrupted depth and it has already cleaned up the edge of the slot in about 2 passes. About 9 to go at .00099 DOC.

The other problem is that on the paper it was about 1/3rd the size it was on screen. But I have high hopes I can make this one work, its sure looking better than anything I've carved before, I have about a dozen disks laying around that just weren't done well enough now.
