If your 3D printer's thread puller jerks or doesn't spin properly, follow these steps to fix the problem:

STEP 1: CHECK THE LEVELING OF THE PRINT BED

  • If the nozzle is too close to the flat, the molten filament may have difficulty flowing properly, causing a blockage in the thread puller's feeding system. Perform a manual leveling of the print bed and clean the toothed gear to remove any dust residue that may hinder proper operation.

STEP 2: CHECK THE PRINT SETTINGS

  • LAYER HEIGHT: Make sure the layer height is set correctly. If it is too high, the material may have difficulty being extruded. The maximum allowable height is half the diameter of the nozzle used for printing.
  • TEMPERATURE: Check that the temperature is set correctly for the material you are printing. If it is too low, the filament may have difficulty being extruded.
  • PRINT SPEED: Check the print speed and make sure it is within the recommended parameters. If the print is too fast, it may cause problems for the thread puller to extrude the material properly.

NOTE: It is advisable to always start with the basic print profiles available in the downloads section https://www.3dwasp.com/download/ of our website, as these profiles are optimized for the specific material and printer.

STEP 3: CHECK EXTRUDER CLEANLINESS

  • Make sure that the nozzle is well cleaned and that the material is extruded evenly. If necessary, clean the extruder (see chapter "Extruder cleaning")
