The LDO Orbiter V1.5 Dual Drive Direct Extruder as seen on Thingiverse. Designed by Dr. Lorincz Rober in cooperation with LDO. 

Features:

  • Compatible with flexible filament
  • Reduced stringing compared with bowden extruder
  • LDO HT motor, which is rated for 180℃ and allows for faster acceleration and direction change
  • Only ~150g weight, resulting in increased print speeds without sacrificing quality.
  • Glass fiber reinforced nylon injection molding parts instead of printed parts for housing, more robust/durable
  • DuPont Delrin injection molded gear, longer lifespan
  • Hardened steel dual drive gear provides bigger feeding force for filament
  • Recommend stepper current 0.35A RMS, don't exceed 0.5A
