Hi, im trying to make some planks to cut with laser with OpenNest and I’ve been having problems with the component : Region Slits . At the moment of taking a look to the surface created by Region Slits (from OpenNest) i can see that some of the pieces have been cutted in half, separeted or not been cutted at all . After trying differents curves, polylines, transformations and also the native Region Slits i havent been able to solve this error.
I’ll be very thankful if someone is able to help me.
