Symptoms
Filament does not stick or is over-squished.
Causes
- Incorrect Z-offset
- Print bed not properly levelled
- Wrong temperature
Solutions
- Level the print bed carefully
- Adjust Z-offset
- Print the first layer slower
- Clean the bed
Systematic Troubleshooting – Step-by-Step Approach
- Analyse the symptoms precisely – When does the problem occur?
- Change only one setting at a time – Otherwise the cause is hard to trace.
- Print a temperature tower or retraction test – For targeted optimisation.
- Maintain mechanics regularly – Check belts, screws and guides.
- Consider filament quality – Moisture is a frequently underestimated cause.
Conclusion
Most 3D printing problems can be traced back to a few core causes: temperature, adhesion, mechanics or material. Those who proceed systematically and document their print parameters can quickly identify and permanently fix issues. With some experience, troubleshooting becomes routine rather than frustration.
