Why is my printer not extruding correctly?

  • The print bed is too close to the print head during the first printed layer. Calibrate the height by following the print bed calibration (see Manual 3D printer Mike 2Chapter 8).
  • The printer has run out of filament.
  • The filament has become entangled in the filament chamber. Check the filament in the filament chamber.
  • The filament is stuck in the print head. Use the filament change procedure (see Manual 3D printer Mike 2chapter 7) to remove the filament, cut off a piece of it and reinsert it.
  • The print head is clogged and the print head needs to be cleaned. Carry out a cleaning process (see section 2).
  • The printed part has a rough surface with small bubbles. This can happen if the filament is damp because the filament chamber is OFF or it has been stored in an uncontrolled environment.
    • Check whether the filament chamber is connected.
    • Replace the filament with a filament that has been stored in a dry and warm environment.
    • Leave the wet filament in the (heated) filament chamber for at least one day without printing to dry it.
