6445 and power/speed test can't run

Don’t know what you mean here. Can you clarify or a photo?

You cut settings are set to line mode,

cut-lines

This is a similar gradient

If you watch the preview, you can see it’s only doing the outline of the boxes as they are set to ‘line’ in the cut parameters.

It’s not giving you a gradient. I’ve changed your file, try this. Then we’ll work on why it’s stopping…

Try reading these docs on the cut/layers from Lightburn.

You may wish to upgrade to the latest version of Lightburn. The current libraries are suffixed with .lbrn2

Good luck :slight_smile:
