11 Before starting a printing process

Before you start printing, a few things need to be checked.

• The print area is located on the print bed.
• The Print bed is empty.
  Make sure that there is nothing on the print area (e.g. another printed object).
• The print bed is clean.
  If the printing surface is dirty (dust, grease, etc.), the extruded material will not adhere to the surface. Check that the surface is clean. Further information can be found in section 14.1.
• Enough filament
  Open the filament chamber and make sure that there is enough filament on the spool.
• Clean nozzle
  Material may stick to the nozzle of the print head from previous use. If this is the case, remove it with tweezers or the cleaning tool. Further information can be found in section 14.2
