Pocket at edge of stock

I have a pocket that goes to edge of stock. How do I get a toolpath for that (it seems this confuses the toolpath generator).

I just tested and a 6 inch square on a 6 inch square piece of stock works fine, and I’ve never noticed that there’s a problem with any feature aligned at the edge of the stock — most likely it’s a problem with the geometry. Likely candidates:

  • unclosed path — close it
  • overlapping geometry — don’t select overlapping geometry when generating toolpaths
  • incorrect path direction — use a Boolean operation to fix this

Thanks - it was overlapping geometry by such a small amount it was not visible even at moderate zoom.
