Overlapping edges get cut twice or does Krabzcam auto deduplicate that part of path?

Here is my job cut path… If my triangles share an edge; I’m guessing it will cut the shared edge twice unless I remove that side of one of the triangles? Thanks for your ideas

yes, most CAM programs do a poor job of eliminating duplicate lines.

hmm, you may want to try the gcode cleaner script that’s been posted here, I
think it’s supposed to remove duplicate lines.

f my triangles share an edge

You must include the diameter of the tool in your calculations; if you are going to make an external cut, you can leave the triangles separated by the same distance as the diameter of the drill bit.

Thank you for the reminder on that.

I know Fusion 360 has the ability to select which edges to be cut. But fusion also requires full 3D model in order to select the edges.

I think I sorted out how to do this. Basically need to make all the triangles all one path… so I traced over all the triangles using the pen tool in inkscape > saved as svg and pulled into Krabz and used the Engrave setting.
