Step completion
- 1Document the failure and confirm that it matches this guide: Axes are not perpendicular, dimensions differ by direction, or gantry travel twists.Not completed
- 2Return extreme overrides to a known printer, nozzle, material, and slicer profile so the diagnosis starts from a stable baseline.Not completed
- 3Check loose frame fasteners. Place the printer on a stable surface.Not completed
- 4Check assembly not squared. Measure diagonals.Not completed
- 5Inspect uneven feet or table. Loosen and square methodically.Not completed
- 6Rule out gantry alignment error. Recalibrate after mechanical correction.Not completed
- 7Change only the single setting or hardware condition supported by the evidence, then run a small test that reproduces the original failure.Not completed
- 8Compare the test against the target condition, record the successful value, and save it in a printer/material profile before repeating the full print.Not completed
Observations and winning values
No notes recorded.
Verification test
- Model
- Small representative test print
- Setup
- Use the same printer, material, slicer and key settings as the failed model.
- Pass
- The original symptom is absent and the target feature is repeatable.
- If unchanged
- The symptom remains in the same location or stage.
