Troubleshooting

*These are my personal experiences, your experience may vary.*

PLA

  • Symptom: Extruder stops extruding, motor is still turning
    • The Filament Drive Gear can strip the filament if the force to extrude it to great. This can be cause by a range of factors:
      • Temperature is too low
      • Nozzle is on the bed (too much back pressure)
      • Nozzle is plugged
      • The feed rate is too fast OR too slow
  • Symptom: Extruder stepper motor makes knocking noise
    • The set screw is too tight and is stalling stepper motor
