I’m currently working on glass engraving (wine glasses and glass trophies) using a CO₂ laser with LightBurn.
I’ve seen a lot of recommendations about working with bitmap images (JPG/PNG) and using Image Mode → Stucki, since it seems to produce a cleaner, more refined result compared to vector engraving.
From your experience, I wanted to ask: Have you tried this approach, and are there better engraving methods for glass?
What do you consider the best methods for engraving glass in LightBurn?
I’d also really appreciate any recommendations for line interval (DPI), power, and speed that work well specifically for wine glasses or glass awards.
Impossible. You need to fine the best settings for YOUR setup. Laser, power, type of glass etc. Not a single setting of any other user will give you the best results. They can give an idea where to start from, but that’s all. Lasering is about testing.
Same as above. The best method is the one that best fits YOUR requirements. I might have some settings that I love but would consider them not great. Or the other way around. The best approach is the one that matches your expectations most.
You did not say which laser you are using, but 100w is a lot of power and you may have difficulty setting the power low enough to keep from fracturing the glass.
I actually already have some solid settings that work well, but what I’m really looking for is how to improve the engraving and get finer, cleaner finishes.
I have spent many hours and countless pieces of glass trying to get good results wth my 100 watt. I finally gave up. There were always small shards coming off, or it just didn’t engrave. I couldn’t achieve a result I would be willing to charge for. If you do get excellent results, please share your findings with the rest of us.
