Quick Fix Workflow

  1. Check seam placement and whether zits align with layer starts.
  2. Tune pressure advance/linear advance if supported.
  3. Reduce temperature if plastic is oozing.
  4. Tune retraction, wipe, and coasting where appropriate.
  5. Inspect G-code for excessive short moves or model mesh artifacts.

Tune one change at a time. Save the known-good profile before experimenting with speed, supports, pressure advance, or material overrides.

FAQ

Are blobs always a retraction problem?

No. Seams, pressure advance, temperature, wet filament, mesh errors, and power-loss recovery features can contribute.

Should I use AI Doctor for this issue?

Yes, especially when the symptoms overlap. AI Doctor is useful when stringing, blobs, poor first layer, heat, material, and slicer profile issues happen together.
