Tools for assembly

2 Assemble the print head

  • Place aluminum plate onto hex nozzle grooves, then place onto extruder body.
  • Place extruder mount on the top of hex nozzle.
  • Using the the M3 allen, screw 2 M4x20's with washers into the 2 M4 nuts held by your finger on the extruder mount(leave these to M4 screws loose for now).
  • Face hex nozzle forward, tighten M4 screws, check that filament feeds through body and into hex nozzle without catching(you may need to push the aluminum plate to the right while tightening the M4's, so that the filament does not catch).
  • Verify gears don't rub on extruder body.
Required parts
Place aluminum plate with hex onto extruder body
Extruder mount fits onto hex
Hold the M4 nuts as you screw in M4 SHCS screws
Align the extruder mount to hex nozzle hole
Verify that gears don't rub on exturder body

3 Attach fans

  • Using the 2.5mm allen, screw in 4x M3x12 SHCS (Note fan orientation).
  • Align hex nozzle wires under fan duct, then screw in 2x M3x12 SHCS with washers to the extruder body.
  • Using the 1.5mm allen, screw one M2x6 mini blower on.
  • Ensure mini blower is aligned with hex heat sink.
