LightBurn Demo 15 – Speed Comparison: LightBurn vs RDWorks

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 tutorials, hints and tips as well as the occasional speed comparisons between it and RDWorks. This session shows the differences in speed: let’s bring it on LightBurn vs RDWorks!

My thanks to the team at Lightburn for allowing me to embed their videos.

0:01something we get asked a lot is why

0:05light burn why should I pay for software

0:07when software came with my laser what

0:10makes light burn different or better

0:12than for example Rd works that comes

0:14with Rueda controllers we get asked this

0:18a fair bit the broad answer is that

0:22light burn is a responsive development

0:24team we’re by no means perfect and we’ll

0:28never claim to be however we do try very

0:31hard to listen to and respond to

0:32concerns of our users produce new

0:35features that people want and and we

0:39focus a lot on things that improve the

0:42overall user experience and so I what I

0:46mean by that is anything that gets in

0:50your way while you are trying to use the

0:52software are the kinds of things that we

0:54want to address and fix so had an

0:57interesting example recently we had a

1:00user send us a file that he said was

1:03causing light burn to freeze so this is

1:06that file this is a vector traced

1:11tree-stump

1:12converted from a bitmap into vectors

1:15when the user ran this file he said it

1:18was freezing up when he tried to send

1:20the job to his controller I have a

1:24fairly beefy gaming system that I use

1:26for development so when I run this file

1:29on the currently deployed version of

1:32life were in the shipping version 9.0 7

1:34and it takes about one minute 31 seconds

1:37sorry pardon me it takes 3 minutes and

1:3910 seconds to process this file 3

1:42minutes and 10 seconds for it to

1:44generate from the moment that I click

1:46the preview button until it shows the

1:49preview so I can see why the user

1:52thought that it had frozen the timing

1:55bar that pops up for the progress bar

1:57was fairly non-responsive so I took a

2:00look at the content of this file and

Transcript for Speed Comparison: LightBurn vs RDWorks (Cont…)

2:02what it was doing where the work was

2:04going or where the time was being spent

2:06and it’s fairly heavy

2:09I’m going to set this 2.1 interval so

2:14the biggest thing causing the slowdown

2:17in this file is this this single line

2:20runs all the way around the outside of

2:23this shape and in order to path plan

2:27this or to do raster scanning of this

2:29shape the software has to figure out

2:32what is inside and what is outside

2:34shapes so as an example if you have the

2:38letter O the software needs to scan the

2:43inside and outside curve of this in

2:46order to produce a solid filled letter O

2:48it needs to do them at the same time the

2:51only way that it can figure out to do

2:53that is if it knows what is inside what

2:57it has to know that this inner circle is

3:01inside that outer circle so that it can

3:03scan them together if you had more than

3:05one for example this one is inside this

3:09one this one is inside this one you

3:12might have one larger shape surrounding

3:14the whole thing and so on and so the

3:16software needs to go through the content

3:19of your file and figure out what is

3:21contained within what so that it can

3:24plan the job accordingly this is also

3:26used when you are cutting when you say

3:29cut inner shapes first the software has

3:32to know what is an inside shape what is

3:34an outside shape to plan the cutting

3:37path accordingly so if we set all of

3:40this back to the original single color

3:43and I hit go we’re going to time this so

3:48you can watch how long this takes now

3:50I’m timing this in real-time I’m going

3:51to hit the preview button and a little

3:53stopwatch that I’ve got here go this is

3:58going to be in the next version of light

Transcript for Speed Comparison: LightBurn vs RDWorks (Cont…)

4:01burn so we found a bunch of places where

4:05some work was being done that we could

4:07reuse and some things that we could do

4:12that we’re a little bit more clever and

4:13so that took 18 seconds

4:18to do that from start to finish that is

4:23considerably better than the three

4:25minutes that it used to take you’ll also

4:28notice that I mean in general light

4:30burns user interface is quite responsive

4:33this file just this one line on the

4:37outside contains over 30,000 nodes and

4:40they are quite heavy they’re all splines

4:43so they have to be subdivided and you

4:46know drawn as smooth curves and so on so

4:49it’s it’s a fairly heavy piece of

4:51geometry that’s being processed so to do

4:54all of this in 18 seconds is a fairly

4:58significant feat I’m not going to show

5:00you our D works trying to do this

5:02because it takes too long but I have

5:05another file that is similar that I’ve

5:07prepped for this and this is a piece of

5:11a Florida map and it has a very similar

5:14problem in that it has this one outline

5:19if I highlight it in red here you can

5:21see it this one shape is one single

5:24continuous line that’s quite complex and

5:27runs all the way down here doubles back

5:30over on itself goes up and around and so

5:32on the software has to figure out that

5:37all of these small shapes are inside

5:41that outer line this red line and doing

5:46that takes a reasonable amount of time

5:48in fact running exactly this file in our

5:52D works takes about five minutes and 20

5:56seconds to process this using these

5:58settings so and by these settings I mean

Transcript for Speed Comparison: LightBurn vs RDWorks (Cont…)

6:010.1 millimeter interval set to fill

6:04nothing special in the overall planning

6:07or optimization options and because

6:09we’re doing a fill there’s no real path

6:11planning involved here it’s just a

6:13straight fill so in light burn I’m going

6:16to run this again and I’m going to time

6:18this one as well so here we go

6:30so that took about seven and a half

6:32seconds now you can run this same file

6:38if you could find it in our D works I

6:41promise you that it takes the time that

6:43I say it does our t-works took five

6:46minutes and twenty seconds to process

6:47this file now the previous release of

6:50Leiper and the 907 release took one

6:52minute and 31 seconds to process this

6:55file which is better than our t-works

6:57but certainly not as good as what we’ve

7:00gotten what we’ve gotten it down to so

7:02the new version of light burn will run

7:05this in about seven and a half seconds

7:07significantly better I’ll show a couple

7:10of other small demos you’ve probably

7:13seen this file before we’ve used this in

7:17a couple of video demonstrations before

7:19so I’m going to show you this one in

7:22light burn so watch that’s how long it

7:26took to scan path plan do all of the

7:29inside-outside sorting and produce the

7:32preview simulate the preview and draw

7:34the final picture and so that all

7:36happened in this amount of time right

7:39there if I go to our D works and import

7:44that same file just opening the file

7:48takes you know a little bit of time

7:51you’ll notice that navigating if I click

7:53and drag the view navigating this file

7:56is not very fast if i zoom out or zoom

7:58in

Transcript for Speed Comparison: LightBurn vs RDWorks (Cont…)

8:00once you’re zoomed in things move a

8:02little bit quicker but if you’re looking

8:04at the file overall if you’re looking at

8:06the full file it goes about this fast

8:08compare that to the view in light burn

8:11things move much faster and much more

8:13fluidly if we go back here I’ve got this

8:17set to scan set to 0.1 millimeter

8:22interval I’m going to click the preview

8:24button and time this

8:33so that took about five and a half

8:36seconds and if we drag this out just a

8:41little bit you’ll notice even painting

8:44the preview takes a reasonable amount of

8:47time you know it’s not terrible but it’s

8:50not instant and you can actually watch

8:53it painting and if I drag the view and

8:56move it around you know as soon as I let

8:58go it finishes its repaint now this gets

9:00better as you zoom in closer you can see

9:02things move a little quicker and that’s

9:04good but five seconds five and a half

9:07seconds for it to plan the job so when I

9:11click preview it takes this long and

9:14that’s how long it takes for the preview

9:17to come up if I go and do the exact same

9:19thing with the same file in the same

9:21settings in light burn it takes that

9:24long and moving and navigating and

9:26zooming is this fast so when people ask

9:31me why light burn what makes it better

9:34and is it worth money and so on the

9:37simple answer that I have is that light

9:40burn is responsive and it’s fast and

9:42ultimately your time and my time is

9:45worth money if it takes you 30 seconds a

9:49minute 5 minutes 10 minutes for you to

9:53compute a job to send to the laser

9:55before the laser even starts working

9:57that’s time that you’re wasting that you

Transcript for Speed Comparison: LightBurn vs RDWorks (Cont…)

10:00could be more productive and so that’s

10:03one among many reasons why we think you

10:06should consider labor thanks for

10:08watching
