Quick diagnosis
Reduce the squashed lip at the bottom of prints by tuning first-layer height, bed temperature, flow, and horizontal expansion.
Most likely causes
- A mechanical change, slicer setting, or material condition is making the printer behave differently than the profile expects.
- The problem is often made worse when multiple settings are changed at once.
- Moisture, worn parts, loose hardware, and old profiles can create symptoms that look similar.
Step-by-step fix
- Raise Z-offset slightly if the first layer is over-squished.
- Lower bed temperature after the first layers if material allows.
- Use elephant-foot compensation in the slicer.
- Check that the model has a small chamfer if it is a functional part.
Before you buy parts
Save your current slicer profile, test with a small repeatable model, and change only one variable at a time. Many 3D printing problems can be fixed with cleaning, calibration, or profile tuning before replacing hardware.
