I've just started setting up jobs and coding on a 95 Bridgeport Torq Cut 22 after 12+ years running pretty typical mills with typical controls. After pulling my hair out learning all the little quirks and rules I must follow on the DX-32 I've pretty much got the hang of this thing, I have a couple of questions, though.

1st of all how the heck do I delete a program off of the hard drive. It looks to have many hundred programs on if from the previous owner and it still says it has 509,000,000 bytes of remaining space left, can this be? How many meg does that equate to? I thought these machines only had 256 KB of space?

2nd question refers to actual programming. I was making some soft jaws and wanted to drop inside a drilled hole with an end mill and interpolate some counterbores and no matter how many J's I added to the G3 interpolation it would only go around 2 times, what's up with this and how do I make it go around more than twice. I'm sure it's just some little rule I'm not following but I can't seem to figure it out. Here's an example of the code I wrote, and as you can see the endmill should go around the inside of the hole 3 times:
