The old ZMap code that allowed the cut-and-lift is not compatible with the new roughing system and has been removed from the project. On the positive side, roughing should be much more accurate and smooth now.

The old standard cut, lift, return, repeat method? :) Any chance of having a parallel roughing option that does do climb or conventional? The old standard cut, lift, return, repeat method? :)

It would be interesting to look at this when I get the machine time estimation code done. There are some extra retracts in the contour code that will have to be fixed. Gerry- Good catch. I'll have to gray-out the direction when using parallel paths. Contour will give better tearout conrtol for wood machining.

How does climb or conventional fit in there? Looks like both? When cutting wood, the back and forth can result in a lot of tearout, so direction is important.

What's the pathlength of the parallel vs. offset roughing? As neat as the offset path looks, there are a whole lot of retracts involved--it looks like the parallel keeps the cutter down in the material more consistently. If I were to make a small UI suggestion, it would be to make "Roughing Style" offset/parallel radio buttons like the "Mill Direction" climb/conventional. And if I'm not mistaken, I think the former name was "Conformal Roughing"--in any case, I'll quietly give up my career ambition of algorithm naming... I like "3D roughing". :) Randy Robert, that’s looking fantastic! What’s the pathlength of the parallel vs. offset roughing?
