Troubleshooting

Diagnosing first-layer adhesion failure, heat creep, under-extrusion, and resin delamination.

Check a repeatable ringing test, model-specific mechanics and the actual firmware shaping feature before tuning motion.

Use the exact printer and resin instructions to separate setup, profile and contamination issues before changing exposure.

Inspect the feed path, profile and model-specific hotend checks before making speculative electrical or mechanical adjustments.

Check material condition and supported temperature, retraction and travel settings with a small repeatable PETG test.

Use a repeatable overhang test and supported material settings to compare cooling, speed, layer time and geometry changes.

Measure repeated bands, inspect the machine using its maintenance instructions and verify one justified repair at a time.
