Just have a question about cutting 1/8th inch clear cast acrylic . I was cutting out some 5"x5" snowflakes and the edges seamed to get charred or wicked. After vector cutting I washed them and tried to clean up the edges by wiping them down but you can still see that there is burn marks here and there. Is this normal ? or do I have to adjust my settings.
I have a VL 200 30W
The vector settings I used were 100p and 0.4 S and 1000 ppi.

When I cut .125" cast acrylic I remove the mask from the top surface and leave it on the bottom. Also air assist and a vector cutting grid makes for better edge quality.Originally Posted by kyna cass

That looks like way too much power. Standard setting for 30W is 65P 0.5S 1000PPI, but that's for 0.2" acrylic. For 1/8" (which is probably really 0.11" or something like that), I'd start at 50P 0.7S and adjust the speed up/down until it just barely cuts through consistently. (Or stay with 100P and bump the speed up to 1.0-1.5.)

Yoga class makes me feel like a total stud, mostly because I'm about as flexible as a 2x4.
"Design"? Possibly. "Intelligent"? Sure doesn't look like it from this angle.

Power and PPI values map ok between different brand/model lasers of the same power, but not speed since the max speeds may not match.
