- Only apply aggressive optimizations to short horizontal moves within
cutter diameter. The safe model STL does not accurately reflect stock
state, so using it for determining long distance move safe heights is
not safe. There would be a high chance of hitting the stock at rapid
speeds.
Thankfully, the vast majority of step-overs tend to be short, so are
still optimized.
- For short moves, only allow completely lift-free transitions when
there is (almost) no Z change, and the min safe travel height does not
rise above the same level.
Otherwise, lift to the max of end points and min safe travel height
first, then move horizontally. A future optimization would be to
directly use the drop scan for transition path generation.
