Inconsistant engraving

I’m frustrated because I’ve been working on a project in acrylic, and can’t get a the Glowforge to consistently engrave at a reasonable depth. Sometimes, I’ll program the design to repeat three times, and that’ll do the trick, but at other times, even that won’t work, and I only get the laser to very lightly engrave the surface,–so lightly that the design is almost unrecognizable.
What am I doing wrong? HEEEELLLLLLPP!

You’ll want to double check your setting each time to make sure you didn’t drop to 1 power for some reason. If that’s not the issue, how are your optics? Have the lenses been cleaned?

Yea—not the power,-but I’ll check the lenses and report back

Finally figured it out—DUH!! The speed was way too high!
