Controlled quality review
CO2 Engraving Defect Checks
Use the observed symptom to select software and record checks, then capture one controlled test and its result. The chart proposes diagnostic checks; it does not claim a universal cause or setting correction.
Content reviewed 2026-11-02. Verify the applicability of each source before using a value in a quote.
Input to record
Symptom, retained artwork and settings, material batch, machine/lens, focus record, one test variable and the acceptance requirement.
Output to carry forward
A reproducible before/after test record with a hold, repeat-test or shop-review decision. Service issues go to the machine’s qualified support procedure.
Test sequence
- Hold the affected job and preserve the original artwork, material identity and settings.
- Filter the symptom table and complete the documented checks before selecting one variable.
- Use an approved coupon, fixed comparison conditions and the same quality requirement. Record raw outcomes, not just a preferred setting.
- Repeat the test or obtain shop approval only within the recorded scope. Unexpected machine behavior, unknown material or unresolved safety issues require stopping and escalation.
Diagnostic test record
Enter your own records. These fields stay in this page until you copy or download them; refreshing clears the draft. Status is a manual shop decision and does not certify a setting.

Sources and scope
Content reviewed 2026-11-02. A documentation reference supports the stated method or data only; it does not approve settings on another machine.
- LightBurn 2.1 Fill Mode
Defines line interval and fill behavior. The area/interval/feed model on this page is an explicit ideal-motion approximation, not LightBurn’s Preview time calculation.
- LightBurn 2.1 Focus Test
Applies to a motorized Z axis controllable through LightBurn. Explains reference positions, Steps + 1 test lines, the Z increment, and inspecting the thinnest line. No universal offset is specified.
- LightBurn 2.1 Material Library
Documents material/operation organization, Assign versus Link, library management, and separate libraries for multiple lasers. The browser worksheet here is a shop record, not a .clb importer or a preset source.
- LightBurn 2.1 Material Test
Documents the two tested grid parameters, fixed base settings, explicit speed units, and preset export. No source settings are supplied by these pages.

| Observed symptom | Checks | Controlled test | Stop / escalate | Method source | Applicability | Confidence | Reviewed |
|---|---|---|---|---|---|---|---|
| Wide or blurred engraved lines | Confirm lens identity, surface height and Z reference against the recorded focus test. | On an approved material coupon, repeat the documented Focus Test within the machine procedure; inspect and record line width. | Unsupported Z control, missing lens procedure or unresolved optics condition: stop and obtain machine support. | LightBurn 2.1 Focus Test | Focus-test method only; does not diagnose all optical or motion faults | Documented focus interpretation; cause must be tested | 2026-11-02 |
| Visible gaps between fill lines | Check the recorded line interval, selected fill area and focus; compare with the approved material test. | Keep material, focus, feed and power fixed while testing one interval change; record appearance and actual elapsed time. | Missing approved material identity or unsafe behavior: stop the test rather than increasing power. | LightBurn 2.1 Fill Mode; Material Test | Uniform fill method; no recommended line interval | Documented parameter meaning; no guaranteed defect fix | 2026-11-02 |
| Uneven fill edges | Check overscan selection and Preview, scan grouping, feed units and recorded settings before changing the artwork. | Compare one documented fill option at a time on the same approved coupon and record edge appearance and time. | Motion/calibration error or collision concern: use qualified machine service; do not compensate with a generic setting. | LightBurn 2.1 Fill Mode | Software fill behavior; hardware faults not diagnosed | Source-supported checks; shop trial required | 2026-11-02 |
| Repeat job differs from prior result | Compare material batch, device/library, actual layer settings and Assign versus Link behavior. | Reproduce the retained test coupon using a captured settings revision; compare the new result against the retained acceptance requirement. | Missing prior record or changed material/coating: hold repeat release and create a new material test. | LightBurn 2.1 Material Library; Material Test | Record comparison; does not assume settings transfer across machines | Documented library behavior; production cause unconfirmed | 2026-11-02 |
Reference workflow
- Match the job, material, machine head, and quality requirement to a row.
- Confirm the source, review date, and confidence before copying the value into a quote worksheet.
- Use a measured result or current OEM record when the row is marked as required or unverified.
