Yes. Increment all Z's. I was hoping there was a way to do that as a chunk which I think would be a rather advanced maneuver and I'm still familiarizing myself with some pretty basic stuff.
As rookie with little experience just blasting away at this I'm not surprised someone with good understanding finds my attempts scary.
Another approach might be implementing tool offsets however I don't think I can call a new "tool" each pass to advance the cutter. Also it appears that I'm limited to 99 tools and this will require about 250 passes at 0.001 per pass.
Maybe a work offset? However they seem more like a use it once per part thing.
There are other many arc patterns to "drop into" this solution when I get it worked out. This is why I'd like to use the vars to somewhat automate the tool advance.
I fixed that incremental move that caused you to break out the
faces. :-)
As far as looking at one line at a time... I'm improving. I just don't see the moves well when I look at the code yet.
