I know there are various issues to troubleshoot when cuts don’t go all the way through (clean the lens, check for warping, etc.). I fine this consistently happens with hard materials like draftboard and plywood.
Anyway, I’m going to suggest adding an option to ‘add extra power’ or bump up a proofgrade setting. Something that adds a little power, slows it down, or adds another fast pass. So we don’t have to click over to manual and tinker with that. “Proofgrade Cut +”
