Metroplex er en Monster Kossel[1] 3D printer, designet og bygget av Jon C, som donerte den til Bitraf.

Den er fortsatt under bygging, ikke klar for bruk ennå.

Undersider: bygging, testing,

Bruk

Om printeren

  • type: Kossel (delta)
  • build volume (diameter x height): 400 mm x 370 mm
  • nozzle: 0.4 mm
  • Hostnavn: metroplex-print.local

Extruder

Extruderen er laget av Dan Cook. Designet er ikke frigitt ennå.

Disassembly

To get access to the inside of the extruder, take out the 3 set screws that are around the base of the effector, pull the hotend assembly down, and you'll have clear access from the bottom for the gear slots.

Remove the bearings, and you can remove the hobbed wheel and the drive gear.
