Lightburn cutting outer border twice?

Hello,

I have been using Lightburn with no issues until today. Not sure if the latest update has something to do with my issue?? For some reason Lightburn is cutting my outer border twice. My design has 6 holes and a box around them. It’s supposed to cut the holes first then cut the box around the holes and be done. But for some reason it cuts the box again?? The pass count for the whole diagram is set to 1. I have looked all through the setting in Lightburn and don’t see any specific box checked or tab that would make Lightburn do this. I copied my design opened a new page and pasted it and it still does the same thing and cuts the outer box twice in the preview. Anything I’m doing wrong?? Or need to look at??

Thanks

Without seeing the design I’ll assume that the outer border has either 2 sets of overlapping or very closely aligned lines.

Take a very close look or try to delete the outer border.

Yeah I zoomed into my border line and there is just 1 line. I opened other designs and they work correctly. So I’m guessing something got messed up when going from Fusion 360 to Lightburn on that one design.

Thanks

Can you upload the .lbrn file or a subset with just the offending piece? Curious what would be causing that.

Do you have your layer set correctly for one pass?

Double click the layer and look for the dialog box to enter how many passes that layer will perform. I can’t remember where it is on the window off the top of my head.

Something to check if you haven’t already, click to select edge that is double cutting (Do not use selecting box), put on different layer, turn that layer off. If you still see the border you have a duplicate.

Here is the file. I made a new file from Fusion and it worked but not sure why this one is doing the outer line twice.

Thanks for the help.

There is an overlapping outer wall. I’ve clicked and moved away in this screenshot:
