Material Test Generator Preview all black

No matter how many ways I modify the settings in the generator the preview always shows all fill squares as solid black. In other words, the 10% power box is exactly the same as the 100% power box. Why?

First, in the preview, try zooming in to see if can discern any lines. Second- maybe your settings are way off for speed and power.

The preview is showing where the laser will fire. I think this is normal when you use fill.

Yep. Tried that. I can zoom and see each individual line of the fill, but theyā€™re all the same color across all squares.

That is your laser beam, it canā€™t change color itā€™s on or offā€¦ You wonā€™t see variations in gray or tones.

Hereā€™s a test file I built from scratch where the preview shows the different shades. Thatā€™s what I expected the generator to do for me.

Have you tried any of the on-line sites that build theseā€¦

I havenā€™t used the generator myself, but I know when I do a ā€˜grayscaleā€™ itā€™s basically black same on the Ruida control panel. I understand it just puts a dot where the machine would and it canā€™t know the materialā€¦

Iā€™d have to see how you did your routineā€¦ wouldnā€™t surprise me if I goofedā€¦

Do you mind posting it? I like to lookā€¦

Well Iā€™m brand new to LIghtBurn and to lasers in general. Only had mine for a couple weeks. So what is it youā€™d like to see? Not sure what you mean by ā€œroutineā€. :slight_smile:

I get what you are asking- in Lightburn that is called ā€œshade according to power.ā€ So I guess they donā€™t show that in the preview!

Iā€™m not sure how you setup your generator or routine to get that outputā€¦ Sorry should have been more clear.

If I highlight your question and click on ā€˜quoteā€™

Drop the .lbrn2 file on the reply window, so I can load it and examine itā€¦ You can also use the download-icon-lightburn in the tool bar.

Donā€™t sweat the newness, weā€™ve all been there.

Take care
