Poor results when laser etching plastic
I'm getting really ugly results trying to laser etch various plastics, whereas MDF and cardboard get good results.
Some samples - including a plastic jawbone adapter and a generic plastic enclosure:
Here are some images I'm using:
I've tried adjusting the pixel and power settings to prevent the burn marks but that usually removes any lighter parts of the image.
Anyone else getting better results, or having similar problems?
Is this a good question?
