Clean the extruder gear

Filament dust compacts in the extruder gear teeth and causes under-extrusion. Brush it out before prints start looking patchy.

You'll need

  • Brass brush
  • Hex key
  • Tweezers
  1. Unload filament

    From the AMS or the toolhead — make sure nothing is in the path.

  2. Open the side cover of the toolhead

    Two screws on the side panel. The drive gear is the small toothed wheel inside.

  3. Brush out the teeth

    Brass brush, gentle strokes. Tweezers for stubborn flakes. Don't blow into it — moisture is the enemy.

    Why this matters
    If you see shiny metal teeth again, you got it. If it still looks fuzzy, keep brushing.
  4. Close everything up

    Re-seat the panel, screw it back, and reload filament.
