Path Sorting Issues

[dubstar-04]

I am looking for some ideas to help make this op work:

I would like to cut from the outside in and from the top down, one z height at a time.
Once one z height is complete I would like the tool to start again at the next z height from the same start point (as set).

These are the path params that I have been using and whatever I try I cannot get the correct tool path. It either cuts from the inside (slotting) or plunges at double depth.

obj.PathParams = "{'orientation': 1, 'direction': 3, 'sort_mode': 3, 'feedrate': 0.0, 'feedrate_v': 0.0, 'verbose': True, 'resume_height': 74.5, 'retraction': 76.5, 'return_end': True, 'preamble': False, 'start': FreeCAD.Vector (-112.5, -22.5, 76.5)}"

The sort mode doesn't seem to have any affect. I have tried None, 2D5, 3D and Greedy.

Like that?

Like that?

Thanks for the reply. The path isn't quite what I was after because the second stepdown in done 'inboard' causing slotting.

Thanks,

Do you have an idea for my problem:

I am continuing to experience issues with the path sorting.

I have a commit https://github.com/dubstar-04/FreeCAD/c ... df4d47c06c to expose the cut direction to force the direction for facing and pocket operation's, the problem i am experiencing is that I can't get the paths to sort by z height (see attached gif)

I am using the 2D5 sorting method with the expectation that the paths are sorted by z height. The description for 2D5:


"'2D5' explode shapes into wires, and groups the shapes by its plane. The 'start' position"
"chooses the first plane to start. The algorithm will then sort within the plane and then"
"move on to the next nearest plane."

Is there something I am missing?
