I was wondering if anyone engraveda silicone bib and what setting they used. I have a creality falcon a1 10W
Depends a lot on the color. I have tried some silicone wristbands, you can do something like start at 6000mm/s 20% power and not move anything after the engraving is done, just check if the effect is good. If not let it run again slower or with a bit more power or just for another pass.
