Lightburn Demo 04 – Arc Recovery (it’s really fast!)

The Lightburn Software Series

The Lightburn Software is probably the best generic laser cutting software available (I use it for almost all of my laser work). This series has LightBurn tutorials, hints and tips as well as the occasional speed comparisons between it and RDWorks. My thanks to the team at Lightburn for allowing me to embed their videos. In this video We take a look at LightBurn Arc Recovery.

An older demo video showing the arc-recovery on import for DXF files. This is largely made unnecessary by the interactive arc fitting tool, but having as an import shortcut makes it quicker to use.

0:00 I thought this would make interesting

0:03 tests it’s a file that was submitted by

0:06 one of the beta testers and if you look

0:07 at this it is just the same logo copied

0:10 over and over and over again

0:12 if you ungroup it and look at the points

0:16 in it there are a lot of points

0:20 apparently this was exported from

0:22 Inkscape originally as a DXF something

0:25 like that so it used to be actual proper

0:30 curves but that information has been

0:33 lost when it was exported Inkscape and a

0:35 lot of other programs when they’re

0:36 exporting DXF convert to teeny teeny

0:39 little lines because they don’t like

0:40 dealing with Autodesk’s spline format so

0:45 I thought it would be interesting to see

0:46 how well my Arc fit the new code that I

0:49 have would deal with stuff like this so

0:52 I set it up so if I hold down the

0:54 control key when I’m importing a file

0:56 it runs the arc fit now notice when I

0:58 import this when I just drop it in takes

1:01 about that long that’s pretty quick

1:03 there’s a lot of information here but

1:05 it’s really not that bad as files go

1:07 however I’m gonna do the same thing now

1:10 with the arc fitter enabled so I’m

1:12 holding down the control key when I let

1:14 this go takes about that long again now

1:19 however if you look at the file if i

1:21 ungroup this and look at the points

1:23 there is a lot less crap in here so all

1:26 of these been properly recovered there’s

1:28 a few extra splines in here but

1:31 realistically this is about as clean as

1:34 you’re gonna get so I rather happy with

1:37 the performance this is working better

1:39 than I actually expected it would and I

1:42 thought it was a nice result
