Why this matters

Check source pixel dimensions, final mm size and chosen line interval together before adjusting contrast or sharpening.

Image engraving is a chain of source quality, physical size, line interval, processing mode, material response and laser setup — no single slider fixes every image.

How to think about it

Define the result you actually need, then confirm the active machine profile, units and operating mode before changing parameters.

Practical workflow

  1. Define the result you actually need, then confirm the active machine profile, units and operating mode before changing parameters.
  2. Change one meaningful variable at a time and use Preview/Frame or offline analysis before running a real job.
  3. If the issue repeats, keep evidence: Console output, a G-code sample, the exact settings used and material context. Evidence makes troubleshooting reproducible.
