Improvements and features over previous versions of Orbiter:

  • Shorter hardened drive gears 11mm vs 15mm manufactured by Bondtech
  • Weight reduced to ~135 grams
  • Smaller more compact dimensions (11.6% shorter)
  • New motor design offers ~40% increase in extrusion force in real printing conditions and much improved acceleration performance
  • Flipped drive gears – filament path closer to the extruder center for a more balanced design and perfect fit on delta printers as well
  • Stainless steel filament exit guide with 0.2-0.3mm clearance to drive gears for best TPU printing experience and extreme wear resistance when using abrasive filaments.
  • High temperature resistant housings, GPA12
  • Machined PEEK secondary drive gear sleeve
  • Tension mechanism with grab screw design
  • Mounting screws in line with filament exit path – improving housing stiffness and easier mounting
  • Perfectly aligned filament path
  • New smaller and more stylish PTFE tube input coupler
  • Motor position rotated by additional 10 degrees for easier maintenance and assembly
  • Extremely low backlash ~0.06mm
  • Filament sensor add on with auto load and unload button add on feature
  • And many more small changes to improve mechanical accuracy and design look

Basic Configuration

  • Steps: 690 steps/mm @ 16 micro-stepping
  • Max. instantaneous speed change (jerk): 600mm/min(RRF), 10mm/s (Marlin) (recommended 300/5)
  • Pressure advance: 0.02~0.03s – to be calibrated
  • Retraction: 1~1.5mm – to be calibrated
  • Retraction speed: 120mm/s, reduce it to 30mm/s when printing TPU
  • Motor current: 1.2A Peak or 0.85A RMS (LDO-36STH20-1004AHG)
  • Max. acceleration: 8000 mm/s2 *
  • Normal motor operating temperature: 65-75°C
  • Drive motor with stealth chop disabled!

* The extruder itself without filament can handle acceleration up to 25000mm/s2. Adding weight of the filament it drags along its recommended to have acceleration limit set not above 8000mm/s2. To reduce clicking noise of the extruder (due to fast direction change) you may limit acceleration to 3000mm/s2
