How tight should extruder be?

Your printer extruder should be tight enough where the filament doesn’t have too much or too little pressure– you need to find a middle ground. The best way to do this is to do test prints. It’s best to adjust the tightness based on the printer’s filament type.

How do you tighten a filament extruder?

  1. Unload any filament.
  2. Locate the extruder spring set screw on the extruder that needs adjustment.
  3. Use the 2 mm hex wrench that came with your MakerBot Replicator 2X to tighten the set screw completely.
  4. Turn the set screw ½ turn counter-clockwise.
  5. Test the tension on the spring.

How do I know if my extruder is too close to bed?

If your nozzle is too close to the bed, it will plow through the filament, causing a rough, uneven surface. You could have thin patches where the plastic is being pushed into the bed surface.

Is my nozzle too close or too far?

Most printers recommend that the nozzle is at least 0.06 to 0.2 mm (0.002 to 0.007 inch) away from the printing bed. You can check your machine’s software settings to determine if the distance is too far or too close. Many machines display this information as (0, 0, 0) or X, Y, Z coordinates.

Why is my 3D printer scraping the bed?

The best way to fix your nozzle hitting your prints or bed is to slightly raise your Z-endstop on the side of your 3D printer. This is what tells your 3D printer to stop moving down so much. You can also use a Z adjustment in your slicer settings to account for a higher bed surface.
