Quick diagnosis
Reduce blobs from over-extrusion by checking flow, pressure advance, seam settings, and nozzle temperature.
Likely causes
- Flow too high
- Pressure not tuned
- Temperature too high
- Seam placed on visible surface
Step-by-step fix
- Calibrate flow.
- Tune pressure advance if available.
- Lower temperature in small steps.
- Move seam to a less visible edge.
What to check before changing more settings
Only change one variable at a time. Save your current slicer profile before testing, use a small repeatable test print, and compare the result before moving to the next adjustment.
