Fix workflow

  1. Confirm the symptom: thin lines, weak infill, gaps, or missing material.
  2. Record material, nozzle size, layer height, print temperature, bed temperature, and slicer profile.
  3. Apply one safe change at a time so the result is measurable.
  4. Run a small test print before sending a long model.
  5. Save the working profile once the issue improves.
