Material Test Generator & Marerial Library - LightBurn Pro 2.0205

[LElers (Lars Elers)]

Hi All, we have been using our Gweike Cloud 50w for a year in our sign shop with mixed results. We are now trying to set the laser up properly. We are used plotters & wide format printers but everything seem upside down & back to front in the laser world. It took us 6 months to work out, when we hit the space bar to wake up the PC, LB sent the last job to the laser again….
Which test do I use first?

1. In LB Laser Tools are listed, top down\ Focus Test, Interval Test, Material Test
2. LB Documentation lists the order as, Material Test, Focus Test, Interval Test..

Material Library,

We got our fill as 00 Black, our cut line is 02 Red, but I can not add these together under one heading in the library under, 0.8mm Black, is it possible?

In the Cut Settings Editor window, I can add a layer & change it to Cut & change the speed / power, but I can’t change to the colour of our cut line to Red.

Making the line black didn’t work, sent the text as fill, but the laser also cut the outside of letters…

Thanks for you help, Lars

If everything is reversed, you should check if your machine setup is correct and matches your physical home position before you can test anything.

Good that you’ve figured it out, even though I think half a year is a long time for that

@LElers

After your machine is set up correctly, I will start with laser beam alignment. Without that and the right focus, serious work is not possible.

Get familiar with your machine and LightBurn, use “absolute coordinates” if possible and do a material test for all the materials you want to work with. Do not rely on preconfigured material libraries or purchased lists, the machines run differently, even if they are the same machines.

The first line is as it should be, many use red layer as cutting layer. You can give your layers names it makes it easier to navigate around and you can make their properties as default for the selected layer.

The second line you need to explain a little more, I am confused about the 0.8mm you mention in this context

@LElers

In the Cut Settings Editor window, I can add a layer & change it to Cut & change the speed / power, but I can’t change to the colour of our cut line to Red.

It works the other way around, you select the item you want to cut, assign it to the appropriate layer and then change the parameters. You save the projects with the parameters you have used for the current layer (if this function is selected) and it will be the same when you open the file again.

If you have selected fill and the selected item is cut out after fill, then it is probably a sublayer or an extra layer that is the cause of it. And that is as it should be, both tasks are completed one after the other.

If that is not what you are experiencing or thinking, please post a small example file here, that is usually the easiest.

Nb. Sublayers (Multilayers) behave differently, here both layers are the same color “on the same layer”, but with 2 or more different parameters. This makes it a bit complicated but has its advantages

It isn’t clear if you resolved this or not. Ensure these are enabled and that should solve the problem.

I would do the focus test first. You need to have your focus point set properly for the interval test or material test to give accurate results. The Interval test should be next because having the proper line spacing affects the results of the material test.

@LElers

I can not add these together under one heading in the library

No, the material library holds the settings for one layer only in each item.

@LElers

I can’t change to the colour of our cut line to Red.

This article explains layer colors and how to change them.

Need more / better explenation of this, perhaps with screenshots (no phone pics please)
