I like to write sometimes with an actual pen and paper. The other day I made a typo and, completely on instinct, my left hand made the Ctrl+Z movement… 
Hello,
The only solution here is the “Offset Fill” function. Offset Fill is faster and does not use line-by-line mode.

Offset Fill has its own issues and may not produce acceptable results due to artifacts. There is also a dramatic difference in the burn between using Constant Power and not using it.
Thank You all for your thoughts and support!!.. There are times that I get so frustrated wtih LightBurn that I want to change but this Forum and the folks here always get me back on track..
I’ve worked with computers for half a century. One of the things I learned was when you get frustrated you make mistakes.
It’s best to go out and sit on your couch with a cup of joe. Even if you’re not thinking about it, it’s continually processed in your brain, similar to a background task. Usually if you sit on it long enough it’ll come to you.
If it doesn’t come to fruition, then just ask here. It’s nice to have a Forum like this to ask for help, make use of it.
In cuts/layers click drop down and look for offset fill. Then adjust the spacing, lines per inch or mm to vari the results.
