Looking for a Lichtenberg pattern too to carve on Carvewright

Looking for a Lichtenberg pattern too to carve on Carvewright so I can fill with epoxy resin

Does this work? Lightning simulator by BadNormals.

I'm sorry to trouble you, but I had a stroke and am trying to relearn this system.
I downloaded your pin pattern but could not get it to appear on my board.
The pattern appeared, nut I could not make any size adjustments, etc.
I continued to get a "Retry. User not authorized" message".
Can you help me understand what to do?
Thanks, Don

Unfortunately, ptn files can not be modified unless you made them yourself but they should be re-sizeable. So not sure what is happening there.

Try importing this image file (first one): File > Import > Import Image File>. This should be modifiable.
