The software is not correctly calculating the engraving path on this PNG, not sure what is wrong with it. I’m going to try thicker lines.
(The error is at the top where it cuts off part of the pacman)
You are about 5 versions behind. Update to the latest (0.8.07) and try that again - if you still have the issue, let me know, but I suspect this is something that’s been long fixed.
Yes, email me the PNG file and the LBRN file so I can have a look. Developer at LightBurnSoftware dot com.
