Practical guide
How to diagnose first-layer problems
A repeatable first-layer test that changes one variable at a time instead of guessing.
Follow in sequence
Step-by-step guide
- 1
Clean the build surface using the method approved for that plate.
- 2
Confirm the slicer has the correct nozzle, plate and filament profile.
- 3
Inspect the nozzle and plate for debris that can affect probing.
- 4
Run the printer's leveling and nozzle calibration routines.
- 5
Print a single-layer test pattern that covers the center and corners.
- 6
Read the line shape: round separated lines are too high, heavily ridged lines are too low.
- 7
Change only one relevant setting, then repeat the same test.
Tools and preparation
Dish soap where plate-compatible, lint-free towel, calibration model and slicer profile notes.
- Do not compensate for a dirty plate by forcing the nozzle lower.
- Avoid touching the print surface after cleaning.
Common questions
Is this safe for a beginner?
Yes. Start with the non-invasive checks and stop if the guide identifies a safety or warranty boundary.
How long should the checks take?
The typical diagnostic window is 20-35 minutes, although drying time, updates and intermittent faults can take longer.
What should I record before contacting support?
Record the exact device model, software or firmware version, the full message shown, when the problem began and which steps changed the behavior.
