Diagonal Lines in an Engraving? Repeat by Position and File
Repeat the unchanged project on a second identified sample and second bed position before deciding that diagonal lines are material, file, or machine related.
Start with the decision, not a setting
A July 2026 user reported rough cast-acrylic engraving with unexpected diagonal lines and was advised to repeat by position and material.
The useful method here is reproduction matrix crossing retained project file, second bed position, second stock piece, scan direction, and unchanged parameters before escalation.
Record the comparison that can change the answer
| Cell | Stock | Position | Interpretation |
|---|---|---|---|
| A1 | Sample A | Position 1 | Original condition |
| A2 | Sample A | Position 2 | Position-following check |
| B1 | Sample B | Position 1 | Stock-following check |
| B2 | Sample B | Position 2 | Confirms interaction or non-repeat |
Follow the evidence in sequence
- Identify substrate and any film before output; reject unknown or PVC/vinyl/halogenated film.
- Preserve the unchanged file, scan direction, and values.
- Run the four safe cells on supplier-confirmed eligible samples.
- Escalate only the repeated pattern with photos and sample IDs.
TYVOK X1S Pro facts for same retained project file
A large X1S Pro work area makes position comparisons possible, but four cells cannot guarantee a diagnosis; see the current TYVOK X1S Pro configuration.
The four-cell artifact test excludes PVC, vinyl, halogenated, or unidentified films and stops at abnormal fumes, residue, flame, or heat damage.

- Separate material lot from machine zone
Buyer questions about same retained project file
Does one repeat diagnose hardware?
No. One repeat only changes the evidence; it cannot diagnose hardware with certainty.
Can unknown protective film stay on?
Do not laser unknown film or plastic. Identify it and remove it only when the supplier instructs; refuse PVC, vinyl, halogenated, or unknown film.
When should support receive the file?
Send the preserved project, software version, four-cell map, photos, and redacted video when the symptom repeats.
