Why is laser engraving blurry, doubled, offset, or unexpectedly faint?

Short answer
If the machine is grinding, has crashed or lost its position, or anything else about it looks, sounds or smells wrong, stop it and call qualified service without trying to make it happen again. Otherwise, confirm the artwork and import settings first: correct dimensions and resolution, no duplicate objects, intended engraving mode, and no unintended scaling. Then use only manual-approved checks for material flatness, focus, secure stock placement, accessible optic cleanliness, and whether the machine reports a normal exhaust, cooling, and motion state. Then re-run a small known reference file on approved stock with your documented settings.
Start with the file, then the checks your manual allows, then a small known test. If the test also fails, more changes to artwork and power will not help; hand it to qualified service with a photo and error history. Conceptual routing only, not a photo of any defect.
If the reference also fails, stop changing artwork and power settings. A reference that also comes out doubled, offset or faint is a machine problem for qualified service, not something to diagnose yourself. Do not reach into moving equipment, tighten internal components, or remove covers; record a photo and error history for qualified service.
