LightBurn Tutorial 20 – Virtual Array

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. In this LightBurn Tutorial Session, we learn all about the Virtual Array feature. My thanks to the team at Lightburn for allowing me to embed their videos.

Contents

Virtual Arrays are new to LightBurn 1.0. This video explains the feature, and shows you how to use them.

This video is the last of the LightBurn Software Series. Why not try out one of our other video series such as:

The Lightblade Learning Lab is a series of videos that Russ did for Thinklaser Limited based on using the Lightblade 4060 Laser Cutting and Engraving Machine. The Lightblade 4060 has a 400 x 600mm bed size and was supplied with a 60W EFR laser tube.

The Tangerine Tiger Series where Russ has purchased a new 500 x 300mm, 50W laser machine from eBay with a view to modifying and upgrading it. In fact, he rips out the glass laser tube and high voltage power supply and replaces them with an RF laser source and PSU from Cloudray. Find out how the expensive RF laser source compares to a glass CO2 laser tube and prepare to get your hands dirty!

The Fiber Laser Series is all about Russ’s adventures and investigations with a 30 watt fibre laser, loaned to him by Dean at Lotus Laser Systems. If you are looking to engrave metal, without the fuss of using coatings such as Thermark, Cermark or Molybdenum Disulphide spray, then this is the series for you.

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

0:05you may be familiar with the grid array

0:07functionality built into lightburn it

0:10allows you to select any shape or shapes

0:12and uniformly distribute them in a grid

0:15along the x and y axis like the grid you

0:18see here

0:19the other shapes created with this grid

0:20however are distinct copies of the

0:23original and are in no way linked to the

0:25original shape

0:26you can scale

0:28rotate or move the original shape and

0:31the copies will not change in any way

0:33but what if you wanted the array to

0:34always be synced with the originally

0:36selected shapes

0:37that’s where the new virtual grid array

0:39option comes in

0:41we can select this shape

0:42go to a range

0:44grid array and then create the same

0:46three by three grid that we saw before

0:49but as you’ll see now the other shapes

0:51on the grid render differently with a

0:53dashed pattern this is to denote that

0:55there are virtual objects synced to the

0:57originally selected shapes

0:59if i unchecked the new create virtual

1:02grid option you will see that it goes

1:04back to looking like what you’re used to

1:06but for now we’ll keep that option

1:08checked

1:09then click ok

1:11unlike before i can now scale

1:14rotate

1:16and move the original shape and all the

1:18others in the grid remain synced to it

1:21and of course even though these shapes

1:23are virtual they will still output to

1:25the laser as normal

1:26as you can see in the preview

1:30even better i can change this array

1:32after the fact

1:33for example we’ll create an ellipse

1:35object

1:37select it

1:38select the square on the array

1:41right click and choose add to array

1:45now the shape is included in the array

1:47as if it had always been there

1:49as you would expect i can move the shape

1:51around independently of all the other

1:53shapes in the array

1:55and the entire grid remains in sync

1:57conversely you can select and right

Transcript for LightBurn Tutorial Virtual Array (Cont…)

2:00click any shape already on an array and

2:02choose the remove from array option in

2:05order to exclude it from the grid

2:08you can also select and right click any

2:10shape that is in an array and choose the

2:13edit array option

2:15this will bring up the original grid

2:16array dialog and let you change all the

2:18parameters you had access to when

2:20creating it in the first place

2:22for example i can change the spacing

2:24here

2:26and even change the number of columns

2:30there’s also a duplicate array option

2:33right here

2:34that will copy the array and all of its

2:36associated shapes this is provided

2:38because virtual arrays cannot be

2:40selected directly only the shapes can be

2:43otherwise there’d be no way to make a

2:44copy of the virtual array

2:49last but not least

2:51is the flatten array option which will

2:53convert all of the virtual shapes to

2:55regular shapes making the array just

2:57like the old style non-virtual array

3:00alternatively using flatten array you

3:02can also go to edit array and uncheck

3:06create virtual array

3:07which will also convert it back into a

3:09normal non-virtual array

3:12now virtual arrays work with all design

3:13shapes and objects built into lightburn

3:15not just those shown in this quick demo

3:17and will always output to your laser as

3:19if they were standard non-virtual

3:21objects we hope this will become a great

3:22new tool in your workflow thanks for

3:24watching
