So this is probably a non-issue from an inexperienced laser operator, but is this much dust normal for acrylic engravings?
Also the engrave looks really stippled instead of smooth, but again not sure if this is normal or not.
For issue completeness, I am engraving Inventables green mirrored acrylic at the proofgrade HD base settings of 300 speed, 450 lpi, but changed the power from 16 down to 10 for a shallower engrave.
A bit of elbow grease and a toothbrush gets rid of most of it, but some at the bottom edge it gets really caked on there. The 2 was in the bottom left of the bed, and for some reason my iPad took the pic upside down.
