Try my laser nesting software

A few issues to report:

  • If I use mm units and ‘add rectangle’ of 1010mm, it gets added as 6451.66451.6mm. This scales linearly, it’s not just that one size.
  • Speaking of scaling, when I import an SVG from Inkscape, it comes in 25% larger than the original dimensions. Once back in Inkscape I can easily correct for this growth, but it seems odd. The same thing happens with both ‘Inkscape SVG’ and ‘plain SVG’ formats.
  • I have a few pieces that I want to cut together to have continuous wood grain. I pass these pairs through Deepnest, bring them back into Inkscape, scale them back because of the above issue, and they look fine. When I import the entire set of parts into Deepnest, it treats the pre-deepnested parts as only one half of the pair.

Still a great program, though. It does some really impressive nesting on my fairly right-angled parts.

macOS 10.12.2, Inkscape 0.91, Deepnest 1.0.0

Great!! Waiting for the next update.

here’s the update:

osx >= 10.9: http://deepnest.io/Deepnest-1.0.1-mac.zip
windows >= 7: http://deepnest.io/Deepnest-1.0.1-win.zip
linux (any distro): http://deepnest.io/Deepnest-1.0.1-linux.zip

changes:

  • speed improvements and better thread handling. You should see an average speed increase of 3x~10x
  • added import for DXF and Corel CDR files, and export for DXF files. Note that this is done by sending your file to a central server, so if you’re concerned about that pre-convert to svg.
  • various bugfixes
  • now supports holes in sheets

I installed 1.0.1, and my first two problems have gone away. Pre-nest screen still looks wonky for my full set of parts, but I can’t get any output at all so I don’t know what the nesting output might look like.

Scale set to mm, other settings untouched:

Test parts are pretty minimal:

No output even 10 minutes on:

Here’s a minimal test case: simple_test.zip (1.9 KB)

I don’t see any log files or anything else useful to report.

hm… that’s weird, it’s working on my side. could you try clicking the reset all link in the config page?

here’s a link to a debug build. The background window will pop up (don’t close it), and the console should display any errors that occur during nesting.

Does this help?

applied a hotfix to 1.0.1, try downloading it again if you’re on mac. There was a dependency issue on the mac build that doesn’t manifest in the dev environment…

It runs on my Mac now, and my scale-related problems are gone.

But I still have problems with certain ‘simple’ shapes. I’ll write up some stuff later, but if you want to get the gist of it: create two rectangles in Inkscape, process them in Deepnest, export as SVG, then import that SVG into Deepnest again.

I’m pretty sure the fact that it isn’t a simple polygon gives Deepnest fits, i.e. the cutline between what was the original two boxes causes problems. More details later, unless you indicate it’s unnecessary.

I haven’t considered that use case, but I think I’ll have a feature in the next release that will solve this issue.

happy Christmas and merry Holidays!
