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 3D printer manual MikeChapter 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 3D printer manual Mikechapter 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.
